licensed in the state of California (and Property Owners in particular cases) may perform
work on private or public sewers, requires Contractor registration, and provides for Plan
review, inspection, connection and other service charges.
3 -02 ENFORCEMENT
Subject to due process, CCCSD may impose fines, disconnect sewers, pursue other
enforcement provided in the Code and /or take legal action against any person or persons
who violate provisions of the CCCSD Code. If work subject to CCCSD's jurisdiction,
whether performed under a CCCSD permit or without permit, is determined to be deficient
under these Specifications, CCCSD may:
A. Correct deficiencies itself or by others at the Contractor or Owner's expense.
B. Reject the work and disconnect the work from the CCCSD system at the Contractor
or Owner's expense.
C. Revoke or suspend permits or a Contractor's CCCSD registration for a period of
time.
3 -03 REGULATION OF PRIVATE SEWAGE DISPOSAL SYSTEMS
The design, construction, and maintenance of private sewage disposal systems including
septic tanks and leach fields, and methods of sewage disposal other than CCCSD's public
sewer system are governed by the statutes, ordinances, rules, and regulations of Contra
Costa County and the State of California.
3 -04 ANNEXATION
Only properties within the boundaries of CCCSD may receive sewer service through
CCCSD public sewer facilities excepting only those properties that have current "out -of-
agency service agreements" approved by the Contra Costa Local Agency Formation
Commission.
3 -05 BASIC SEWER SERVICE POLICY
Each property with a separate assessor's parcel number shall have a public sewer
extended to it, unless the property is the last lot that can reasonably be served from a
public sewer with a private side sewer installed within a recorded, appurtenant easement
Section 3 - Code Provisions and Policies Page 29
across the property adjacent to the public sewer. Public sewers are maintained by
CCCSD. Private sewers, i.e., the sewer pipeline from the building to the public sewer,
including the connection tap or wye at the public sewer, are owned and maintained by the
Property Owner.
3 -06 THE LINE SIZE AND SERVICE POLICY
The minimum nominal size of any new public gravity sewer shall be eight (8) inches in
diameter.
Private Side Sewers shall be four (4) inches in diameter for single - family residences.
Other side sewers shall be six (6) inches in diameter or larger. Side Sewers shall be
connected to public sewers six (6), eight (8), ten (10) and twelve (12) inches in diameter at
manholes or by installation of approved taps, wyes or sanitary tees. Side Sewer
connections to public sewers over twelve (12) inches in diameter shall only be made at
manholes unless a specific written Special Approval for installation for installation of a tap
is obtained from CCCSD. Joint use of a Side Sewer to serve more than one property will
not be permitted. All Side Sewers shall be equipped with an approved Overflow Protection
Device.
3 -07 PAYMENT OF FEES AND CHARGES
Plan review and inspection fees, if required, must be paid before any sewer work is
started. Annexation charges and other connection fees must be paid prior to the time of
the connection of buildings to the sanitary sewer system.
3 -08 REIMBURSEMENT PROGRAM
The Reimbursement Program provisions of the Code require that sewers be installed to
provide for logical extension of service that avoids relocation or duplication of facilities. In
the event a line may provide service to a property other than that owned by the installer,
the proportional value of such service shall be determined and collected by CCCSD for the
installer.
A. Reimbursement Procedure
No later than six (6) months after CCCSD's acceptance of a public main
sewer extension proposed for reimbursement, the installer shall:
Pay the reimbursement account set -up fee;
Submit all of the following:
A complete reimbursement account application;
Copies of any agreements regarding the sharing of the costs
that exist between the installer and any other party or parties;
Section 3 - Code Provisions and Policies Page 30
- Contracts, cancelled checks and receipts documenting the total
sewer construction costs; and
- A cost breakdown of pipelines, special structures, CCCSD fees
and charges, engineering and right -of -way acquisition costs.
Failure to submit all of the required documentation within six (6)
months from the date of final acceptance of the sewer work will result
in the job being ineligible for the Reimbursement Program.
2. CCCSD staff will review the application and documentation submitted by the
installer and determines the amount of allowable costs and the initial
Reimbursement Fee (per Residential Unit Equivalent).
3. The CCCSD Board will conduct a public hearing to consider and establish
the initial Reimbursement Fee.
4. The Reimbursement Fee will be adjusted for the effect of inflation and
depreciation whenever a Reimbursement Fee is collected.

SECTION 4
DESIGN STANDARDS
4 -01 DESIGN CRITERIA
A. General
When the estimated average base wastewater flow for the job exceeds
45,000 GPD, or additional flow carrying capacity may be required for existing or
future connections upstream of the job, the Job Engineer shall provide a capacity
study report when plans are submitted for preliminary review. The capacity study
report shall include a table that presents the proposed pipe diameter, slope, length,
Manning's roughness coefficient, full pipe capacity, design capacity (see 4.01.C.
below) and the percentage of design capacity utilized for each proposed sewer
reach. The percentage of design capacity utilized shall be calculated by dividing
the design flow by the design capacity and multiplying by one hundred (100).
B. Design Flow
Design Flow = (Average base wastewater flow times Peaking Factor) plus
(groundwater infiltration factor times acres).
NOTE: Peaking Factor - The peaking factor for the above equation shall be
obtained from Figure 4 -1. Figure 4 -1 was derived from the maximum peak flows
observed (based on 15- minute flow readings) during a two -week dry period in late
January and early February 1985.
Average Base Wastewater - The average base wastewater unit flow factors are
presented in the following table:
AVERAGE BASE WASTEWATER UNIT FLOW FACTORS
Land Use Category

Schools, Churches, etc. )
feet
Groundwater Infiltration (GWI) - The GWI rate for use in the above "Design Flow"
equation shall be 170 gpd /acre, unless CCCSD provides the Job Engineer with an
area - specific rate. This rate is an average for summertime GWI following wet
weather seasons with higher- than - average rainfall in sewers constructed in CCCSD
after 1985.
Section 4 - Design Standards Page 32
C. Design Criteria - Gravity sewers within CCCSD shall be designed in accordance
with the following design criteria.
Design Capacity - Main and trunk sewers shall be designated on the
following basis: (See Figure 4 -1 following)

Section 4 - Design Standards Page 34
a. For sewers eight (8) and ten (10) inches in diameter, design capacity
shall be based on pipes flowing two - thirds full (d /D < or = 0.67).
b. For sewers twelve (12) inches and larger in diameter, design capacity
shall be based on pipes flowing full without surcharging (d /D < or =
1.0).
2. Velocity and Slope - The minimum acceptable slope for sewer pipe is based
upon a velocity of three (3) feet per second for main sewers and a velocity of
two (2) feet per second for trunk sewers, both when flowing full. The
minimum and maximum design flows for each pipe size at the minimum
acceptable slope is provided in Section 4- 02.A.4. However, CCCSD, at its
sole discretion, may allow a lesser slope and /or a larger pipe size on a case -
by -case basis where the elevation of the existing system constrains the
available elevation drop. When the slope of the sewer exceeds twenty
percent (20 %), ductile iron pipe conforming to the requirements of Section
15.15061 of these Specifications shall be used.
3. Pipe Diameter - Diameter of gravity sewers shall be determined by
Manning's pipe friction formula, using a roughness coefficient, "n," of 0.013
or the pipe manufacturer's recommendation, whichever is greater.
4. Pipe Cover and Clearance - Minimum pipe covers and clearance, as
specified in Section 4 -02.C, shall be maintained in the design of sanitary
sewers. If certain conditions exist which make it impractical to meet the
minimum cover and clearance requirements, the conditions and locations
shall be specifically noted on the sewer profile on the Plans. Special
Approval is required for each location where pipe cover or clearances are
proposed to be less than the minimums specified. Special pipe, bedding,
and /or backfill shall be as directed by CCCSD.
D. Individual Lot Pumping Systems will be allowed only in cases where no feasible
gravity sewering alternative exists. If a sewage pumping system is proposed, the
Contractor shall comply with the requirements of Section 15.13100 of these
Specifications.
4 -02 HILLSIDE AND CREEK AREA
A. The Job Engineer shall submit a geotechnical report prepared by a registered
Geotechnical Engineer or a Civil Engineer practicing in Geotechnical Engineering
whenever:
Sewers are proposed to be installed in easement locations where the
existing or proposed cross -slope grade exceeds twenty -five percent (25 %).
2. Sewers are proposed to be installed within twenty -five (25) feet of the top of
a creek bank or fifty (50) feet of the centerline (flowline) of a creek.
Section 4 - Design Standards Page 35
3. Sewers are proposed to be installed in historical slide locations or within the
area of influence of a potentially unstable hillside.
B. The geotechnical report shall address the following:
Geological setting, general soils and bedrock conditions along the proposed
sewer alignment, and recommended setbacks from slides and creeks.
2. Slope instability or other geotechnical hazards in the vicinity of the proposed
sewer alignment.
3. Potential groundwater issues.
4. The effect of trenching and sewer installation on slope stability
5. Recommended requirements for trenching, bedding, backfill, or special
supports that may be recommended.
6. Erosion potential of soils around sewer near water courses.

for other utilities that were used for reference during design;
• Two (2) copies of the plat and legal description for each right -of -way required by
Section 8;
• One (1) print of the subdivision or parcel map, including title or certificate sheet;
• One (1) completed Annexation Request and Petition, for each property to be
served by the job that has not been previously annexed to CCCSD;
• When applicable, a completed Individual Lot Pumping System Application for
each lot to be served by pumped service;
For sewer main extensions to be constructed in existing streets, the following shall also
be completed prior to preliminary design review:
• An underground facility locating company and /or Underground Services Alert
(USA) shall be contacted to obtain field marking of existing facilities prior to
potholing;
Section 6 — Plan Review Page 56
• A properly licensed Contractor shall be engaged to pothole and expose potential
conflicts with existing improvements where determination of actual physical
location is needed for adequate design and clearance references, and the
results of the potholing shall be noted on the Plans.
Upon its first receipt of Plans, CCCSD may perform a field verification to confirm that all
underground facilities have been marked and that the Plans reflect the field marking. If
facilities have not been marked or the Plans do not reflect the field markings, CCCSD
will return the Plans to the Job Engineer without review.
At the conclusion of each preliminary design review, one (1) set of Plans will be
returned to the Job Engineer. CCCSD comments and required revisions will be noted
on the Plans. Once the Plans meet CCCSD's standards, the Job Engineer will be
notified that final construction Plans may be submitted.
6 -04 ADDITIONAL REQUIRED DOCUMENTATION
A. Right -of -way Submittals
For all public sewer installations on private property, an Irrevocable Offer of
Dedication (IOD) for a sanitary sewer easement is required (see Section 8).
Legal descriptions and plats for the easements prepared by the Job Engineer), a
copy of the current deed for the underlying property, and complete traverse,
closure and area calculations shall be submitted prior to the second preliminary
design review. One (1) copy of each legal description and plat marked with
CCCSD comments and required revisions will be returned to the Job Engineer.
Final, wet stamped, original documents shall be included with the final

be filed showing all referenced points.
Copies of filed Corner Records or a letter from the Land Surveyor stating that no
monuments of record were found in the construction area shall be submitted to CCCSD
prior to the issuance of a CCCSD construction permit.
If survey monuments are disturbed or destroyed without having first been referenced,
the Contractor shall engage a Land Surveyor to reset the monuments and file a Corner
Record or Record of Survey as required by law.
Monuments shall be replaced in accordance with the standards of the agency (city or
county) having jurisdiction.
6 -08 COMMENCEMENT OF WORK
No construction work shall commence on a Job until CCCSD has favorably reviewed
the plans, received other required documents and cut sheets, received all applicable
payments and affixed its signed stamp indicating that construction may proceed on the
cover sheet of each set of final construction plans and issued a permit to the Contractor
for the Job.
When any change(s) to job plans are proposed after completion of CCCSD's final
review, or are required due to field conditions being different from those indicated in the
final construction plans, (including, but not limited to, changes of pipe type, class,
grade, cover, quantities or any other details that may affect the sanitary sewer
installation), the work subject to change will be suspended until the change(s) have
received favorable review by CCCSD through the above described process.
If construction is proposed to be done in sections or phases, submittal and approval of
the final construction plans for the entire job shall be as outlined above. A 1" = 100'
scale system map shall be submitted to CCCSD for its approval showing the schedule
Section 6 — Plan Review Page 60
of the phased construction. Prior to the construction of each section or phase, the Job
Engineer or Contractor shall submit four (4) additional prints of the job cover sheet with
the portion of work to be constructed under the particular section or phase "highlighted"
on the 1 " =100' scale sewer system map, cut sheets for the particular section or phase
and applicable CCCSD plan review fees.
The CCCSD permit for construction may be suspended or revoked by CCCSD at any
time if it is determined that any portion of the Plans, cut sheets, and /or construction
work fails to meet all CCCSD requirements. The CCCSD permit for construction will
expire if actual field construction does not commence within three (3) months of the

SECTION 8
PROPERTY RIGHTS FOR WASTEWATER FACILITIES
8 -01 GENERAL
Title 7 of the CCCSD Code, defines and establishes the property rights needed for
existing sewers, structures, appurtenances, and appliances. When new installations of
public trunk or main sewers are proposed, the Job Owner shall obtain, on behalf of
CCCSD, the property rights necessary for construction, alteration, replacement, repair,
maintenance and operation of the new sewers in accordance with the requirements of
this Section.
A. Width of Required Rights of Way
Easements for public sewers ten (10) inches in diameter or smaller, or where the
depth from the ground surface to the flow line (invert elevation) of the sewer is
nine (9) feet or less, shall have a minimum width of fifteen (15) feet. Easements
for sewers twelve (12) inches in diameter or larger, or where the depth is greater
than nine (9) feet shall have a minimum width of twenty (20) feet. If new sewers
will be installed across properties where existing improvements are adjacent to
the new sewers and will remain in place, the easement width may be reduced at
the sole discretion of CCCSD, but in no case, shall the width be less than ten
(10) feet.
B. Use of Sewer Easements
Except for fences and utility, storm drain and retaining wall crossings described
below, exclusive sewer easements shall be used only for purposes of
constructing, altering, replacing, repairing, maintaining, and operating sanitary
sewer pipes, appurtenances, and appliances.
Surface uses of sanitary sewer easements shall be limited to paving and general
landscaping, not including trees. The planting of trees, or construction of
permanent structures including, but not limited to, houses, garages, car ports,
outbuildings, swimming pools, fountains, ponds, parallel drainage swales,
artificial streams, retaining walls or other structures is not permitted within or over
the easement area.
Surface structures (manholes, rodding inlets, etc.) within easements shall not be
covered by earth or other material and shall remain in an exposed and
accessible condition at all times for routine and /or emergency maintenance that
may be necessary to protect adjacent properties.
Section 8 — Property Rights for Wastewater Facilities Page 65
C. Utility, Storm Drain, Retaining Walls and Fences
Utility pipes and conduits, storm drains, retaining walls and fences may only
cross CCCSD subsurface easements at angles between forty -five degrees (45
and ninety degrees (90 to the centerline of the easement, and at elevations
that will not conflict with any sanitary sewer or appurtenance. The following
improvements will not be permitted in CCCSD sanitary sewer easements without
CCCSD's explicit written Special Approval:
• Utilities, storm drains, retaining walls or fences parallel to or with crossings
at angles less than forty -five degrees (45 to the centerline of the
easement;
• Utilities, storm drains, retaining walls or fences, or any part or
appurtenance of these, within six (6) inches wall -to -wall of existing or
planned sanitary sewers or appurtenances at any point;
• Retaining walls three (3) feet or greater in height (i.e., those which require
engineered design and building permits) or having pier foundations or
spread footings greater than eighteen (18) inches wide by twelve (12)
inches thick will not be permitted without CCCSD's written Special
Approval.
D. Acceptable Documents for Property Rights Required for Public Sewers
The following documents are generally acceptable for establishing the property
rights required for installation of public sewers:
• Existing Grants of Easements to CCCSD for sewer purposes.
• Irrevocable Offers of Dedication (IOD) to CCCSD of easements for sewer
purposes.
• Easements dedicated to CCCSD for public sanitary sewer purposes on
filed subdivision maps.
• Existing private access and /or utility easements appurtenant to the
property of the Job Owner that specifically cite "sewers" or "utilities" as
uses, and where it is reasonably foreseeable that extension of the sewer
will not be necessary to serve properties beyond those properties having
appurtenant rights in the easements at some time in the future.
The following documents are generally not acceptable to establish the property
rights required for installation of public sewers:
• Nonexclusive easements for all utilities, "PUE."
Section 8 — Property Rights for Wastewater Facilities Page 66
• Private access and /or utility easements appurtenant to the property of the
Job Owner where it is reasonably foreseeable that extension of the sewer
will be necessary to serve properties beyond those properties having
appurtenant rights in the easements at some time in the future.
8 -02 IRREVOCABLE OFFERS OF DEDICATION BY SEPARATE DOCUMENT
The following procedures shall be followed when separate instruments for Irrevocable
Offers of Dedication (IOD) in favor of CCCSD are proposed to establish the property
rights required for installation of public sewers:
A. Submittals
The Job Engineer shall submit two (2) copies of a legal description and "Right -of-
way Map for Sewer" (plat) for each easement proposed no later than the time
he /she submits plans to CCCSD for second preliminary design review. After
these documents have been reviewed, one (1) copy of each, marked with
CCCSD's comments and required revisions, will be returned to the Job Engineer.
The Job Engineer shall respond to comments, make required revisions and
submit original wet - stamped and signed legal descriptions and plats no later than
the time he /she submits plans to CCCSD for final construction plan review. Once
the documents are favorably reviewed by CCCSD, it will prepare an IOD
document for each easement and send it to the Job Engineer for execution by
the Property Owners. Original properly executed and notarized IOD document
shall be returned to CCCSD for recording prior to issuance of the permit for
construction.
B. Legal Descriptions
A legal description for each proposed easement in the form shown on Figure 8 -1
shall be prepared for CCCSD review by the Job Engineer or Land Surveyor. As
a general rule, easements shall be described by a centerline, sideline, or
perimeter metes and bounds description (as appropriate). The Point of
Beginning and the terminus of the description shall each be descriptively tied to
at least two (2) found monuments of record. Complete recording or filing
information for any lot, parcel or map mentioned in the description shall be
included. If the easement follows the boundary of any particular parcel, tract or
right -of -way, the relationship of the boundary and the easement shall be fully
qualified in the description. All points where an easement crosses or contacts a
parcel or right -of -way boundary shall be fully referenced in the description.
The legal description shall be entitled "Exhibit A ", and shall include the easement
CCCSD- assigned parcel number, the Assessor's Parcel Number (APN) and
CCCSD job number in the upper right hand corner. The description shall also
make reference to the accompanying plat (Exhibit B), by which reference it shall
be made a part of the Legal Description.
Section 8 — Property Rights for Wastewater Facilities Page 67
C. Right -of -way Map for Sewer (Plat)
A Right -of -way Map for Sewer (plat) in the form shown on Figure 8 -2 shall be
prepared for CCCSD review by the Job Engineer or Surveyor for each proposed
easement on a form identical to the example shown in Figure 8 -1. The plat shall
show the entire area offered for the easement. The plat shall be entitled "Exhibit
B ", and shall be drawn so that the north arrow points toward the top of the sheet.
When necessary for clarity, a separate plat shall be prepared for each easement
parcel showing all necessary survey ties, courses, and distances along the
easement. Whenever possible, adjacent roads shall be shown to facilitate
locating the subject easement area. The CCCSD job number, easement parcel
number, and the last name of the grantor shall also appear on each right -of -way
plat
D. After acceptance of the job by CCCSD, the Board of Directors will consider
formally accepting the IOD for each sewer easement.
8 -03 IRREVOCABLE OFFERS OF DEDICATION ON SUBDIVISION MAPS
The following procedures shall be followed when property rights required for installation
of public sewer are proposed to be established by dedication of public streets or
irrevocable offer of dedication of easements in favor of CCCSD on a subdivision map.
A. Certificate Sheet Requirement on Subdivision Final Maps
The following paragraphs shall be made part of the Owner's Certificate when
easements are offered for dedication to CCCSD:
"The area marked "Sanitary Sewer Easement," or "SSE" is offered for
dedication to the Central Contra Costa Sanitary District (CCCSD) or its
successors or assigns in gross, as an exclusive subsurface easement (or

SECTION 11
CONTROL OF THE WORK
11 -01 AUTHORITY OF THE CCCSD INSPECTOR
The Inspector shall decide all questions that arise in the field regarding the quality or
acceptability of materials and /or equipment, completed work and /or the interpretation of the
plans and /or these Specifications. The Inspector's decision shall be final.
The Inspector may suspend a Contractor's work under a CCCSD permit, completely or
in part, for such periods as he /she may deem necessary, due to unsuitable weather,
such other conditions as he /she considers unfavorable for the suitable prosecution of
the work, or due to the failure on the part of the Contractor to carry out directions given,
or to perform any provision of the permit. The Contractor shall immediately comply with
the Inspector's order to suspend the work. The work may be resumed when conditions
are suitable and the Contractor is willing and able to properly resume work, as
determined by the Inspector.
In the event that a suspension of work is ordered as provided above, the Contractor
shall do all work necessary to provide for safe, smooth and unobstructed passage for
public traffic through the construction zone during the period of the suspension of work,
or at the end of each work day.
No decisions rendered, nor directions given by the Inspector shall relieve the
Contractor, the Job Owner or the owner's surety of their obligations or responsibilities to
diligently prosecute the job, or establish any contingent liability on the part of CCCSD.
Should the Contractor fail to act promptly or diligently in the prosecution of work done
under a CCCSD permit, or should the urgency of a particular situation require that
repairs or replacement be made before the Contractor can be notified or can respond to
notification, CCCSD may make or cause the necessary repairs or replacements to be
made or perform the necessary work, and the Contractor shall be charged and shall
pay to CCCSD the cost of such work plus the current CCCSD overhead rate to
compensate CCCSD for administration of work. (CCCSD Code Chapter 5.10)
11 -02 PLANS
No changes shall be made in any plan or drawing after it has received favorable "Final
Review for Construction" by CCCSD, except with CCCSD's written concurrence.
The Contractor shall keep copies of the CCCSD- stamped final plans for the project,
these Specifications and all other governing agency specifications incidental to the work
at the jobsite during prosecution of the work, and shall make the copies available to the
Inspector upon request. The Plans, these Specifications and required supplementary
documents are considered requirements of the work, and the Contractor shall
familiarize itself and fully comply with as such requirements.
Section 11 — Control of the Work Page 88
Submittal of shop drawings and /or other information not included in the Plans is
required under various subsections of Section 15 of these Specifications. These
submittals may include, but are not limited to schedules, fabrication detail drawings,
certifications that materials comply with the specification, evidence of worker's special
qualifications, and information regarding proposed alternate materials, methods and /or
equipment. The Contractor shall provide the required submittals, and receive favorable
review prior to commencing work involving these workers, materials, methods or
equipment.
Review of the Contractor's submittals by CCCSD shall not relieve the Contractor of its
responsibility for the accuracy of dimensions and details or for completion of permitted
work in compliance with these Specifications.
11 -03 CONFORMITY WITH THE PLANS AND ALLOWABLE DEVIATIONS
Finished surfaces shall conform to the lines, grades, cross - sections, and dimensions
shown on the Plans. Only deviations from the Plans and working drawings as may be
required by the constraints of construction and approved in advance by CCCSD will be
allowed.
CCCSD reserves the right to order such alterations, deviations, additions to, or
deletions from the Plans and Specifications covered by any permit or agreement, as it
may determine during the progress of the work to be necessary and advisable for the
proper completion or subsequent operation of the improvements being constructed.
11 -04 COORDINATION OF PLANS AND SPECIFICATIONS
These Specifications, the Plans, and all required supplementary documents are each
an essential part of the permit or agreement, and a requirement cited in one is as
binding as though cited in all. Each component document is intended to be coordinated
with the others, and to describe and provide for properly completed improvements.
The requirements of these Specifications shall govern over citations on the Plans,
unless deviation from the Specifications is specifically authorized by CCCSD in writing.
The permit for work under signed Plans stamped "Final Review for Construction" shall
expire three (3) months from the date affixed on the stamp, unless work has begun
within that period.
11 -05 INTERPRETATION OF PLANS AND SPECIFICATIONS
The Contractor shall request clarification, additional information or direction from
CCCSD if it believes that the work to be done is not sufficiently clear, detailed or
explained in the Plans and /or these Specifications. Upon receipt of such a request,
CCCSD will render a determination as expediently as is practical, and the determination
made shall be final.
Section 11 — Control of the Work Page 89
In the event of a discrepancy between the graphical representation and the words or
figures written on a drawing, the words and figures shall be taken as correct.
In the event that a Property Owner, Developer, Job Engineer, Contractor or other
person fails to comply with these Specifications, the CCCSD Code, or a specific
instruction of the Inspector relative to any work under a CCCSD permit or agreement,
CCCSD may suspend or revoke the permit or agreement until such differences or
deficiencies are resolved.
11 -06 SUPERINTENDENCE
The Contractor, or a representative of the Contractor who is authorized to make field
decisions, shall be present at the jobsite at all times when work is in progress. The
Inspector will communicate any needed determinations or instructions to the Contractor
or its authorized representative. Any determination or instruction given by the Inspector
that is not otherwise required by these Specifications or the CCCSD Code to be in

Prior to being issued a CCCSD permit, the Contractor shall submit the names of its
authorized representative(s), business address and telephone number(s), as part of the
CCCSD Contractor Registration process. Delivery of correspondence or notices to this
address by hand delivery, courier service, express carrier or U.S. Mail shall be deemed
sufficient service.
11 -07 LINES AND GRADES
When the Contractor requires stakes or marks, it shall notify the Job Engineer of the
requirements in advance of starting operations that require such stakes or marks. The
Contractor shall request utility marking from U.S.A. prior to staking, and favorable
review by the Inspector of stakes in the field is required prior to the commencement of
work. If, in the judgment of the Inspector, the stakes or marks suggest that the new
work may conflict with existing improvements, the Contractor shall pothole the existing
improvements to determine whether redesign of the work is required.
Stakes and marks shall be carefully preserved by the Contractor. If any such stakes
and marks necessary to complete construction are destroyed or damaged, the
Contractor shall arrange for such stakes and marks to be replaced.
All distances and measurements will be made in a horizontal plane. Grades are given
from the top of hubs or nails or other points designated by the Job Engineer.
11 -08 EMERGENCY WORK

CCCSD permit for the work on the first CCCSD working day following any emergency
response, and shall obtain the permit prior to requesting inspection of the work.
11 -09 INSPECTION
The Inspector shall have access to the work at all times during construction, and the
Contractor shall provide proper and safe facilities for such access and for inspection.
The Inspector shall be furnished with every reasonable facility for ascertaining that the
materials and the workmanship are in accordance with the requirements and intentions
of the Plans and these Specifications. All work done and all materials furnished shall
be subject to inspection. The Contractor shall submit properly authenticated
documents or samples of materials demonstrating the Contractor's compliance with the
requirements of these Specifications at any time so requested by CCCSD.
In the event that the Inspector determines that any work completed or in- progress does
not comply with the requirements of the Plans or these Specifications, or any applicable
rules and regulations, the Inspector may order that the noncompliant work be corrected,
or removed and replaced, so as to fully comply with the requirements. If the Contractor
fails to comply with any order made under the provisions of this article within a
reasonable time, CCCSD may have the defective work corrected or removed and
replaced at the Contractor's expense.
The Contractor shall call to arrange for CCCSD inspections required by these
Specifications a minimum of one (1) business day in advance of the times such
inspections are required for the work. The Contractor's customer or the Property
Owner may choose to be present during inspections, including during required pre -

secured, shored and covered with trench plates so as to provide for public safety and
unobstructed safe access for vehicular and pedestrian traffic
Where the Contractor's operations are not being satisfactorily controlled or maintained
by the Contractor for safe passage of public traffic, the Inspector and /or other public
agencies having jurisdiction may order the Contractor to correct any unsafe conditions,
and the Contractor shall comply with such orders.
The failure or refusal of the Contractor to properly provide emergency or Property
Owner access, or to employ, control or maintain detours shall be sufficient cause for
suspension of the work until proper access and /or detours are provided by the
Contractor.
11 -15 CLEANLINESS OF JOBSITE

four (4) to six (6) inches below the bottom surface of the pipe, i.e., the
trench sub - grade, and a plane at a point twelve (12) inches above the top
outside surface of the pipe. The sub -zones of the pipe zone are defined as
follows:
a. "Bedding is that portion of the Pipe Zone between the bottom of the
trench or the top of required foundation material and the lowest point
on the outside surface of the pipe barrel excepting bells;
b. "Haunching" is that portion of the Pipe Zone between the top of the
Bedding and the horizontal centerline of the pipe;
C. "Shading" is that portion of the Pipe Zone between the top of the
Haunching and a horizontal plane twelve (12) inches above the
highest point on the outside surface of the pipe barrel excepting
bells.
2. Controlled Low Strength Material (CLSM) shall be provided in lieu of Type I
Bedding and Backfill Material where indicated on the plans. Contractor

levels will be achieved.
B. During spreading, each layer shall be thoroughly mixed as necessary to promote
uniformity of material in each layer. Pipe zone backfill materials shall be manually
spread around the pipe so that when compacted, the pipe zone backfill will
provide uniform bearing and side support.
C. Where the backfill material moisture content is below the optimum moisture
content, water shall be added before or during spreading until the proper moisture
content is within the range where the specified compaction can be achieved.
D. Where the backfill material moisture content is too high to permit the specified
degree of compaction, the material shall be bladed, aerated or dried and /or mixed
with dryer material until the moisture content is satisfactory.
E. Whenever selection is possible, embankment material having a sand equivalent
value of less than ten (10) shall be deposited in the lower portions of
embankments and no such material shall be placed within three (3) feet of
planned finished grade.
F. When the embankment material consists of large rocky material, or hard lumps
such as hardpan or cemented gravel which cannot be broken readily, such
material shall be well distributed throughout the embankment, and sufficient earth
Section 15.02205 - Excavation, Bedding and Backfill Page 136
or other fine material shall be placed around the large material as it is deposited
so as to fill the interstices and produce a dense compact embankment, but in no
case shall any material exceed twenty -four (24) inches in any dimension.

to the specified percentage of maximum density. Equipment that is consistently
capable of achieving the required degree of compaction shall be used and each
layer shall be compacted over its entire area while the material is at the required
moisture content. Compaction at the top of the pipe zone shall be done using a
plate compactor.
B. Flooding, ponding, or jetting shall not be used.
C. Equipment weighing more than ten thousand (10,000) pounds shall not be used
within a horizontal distance equal to the depth of the trench. Hand operated power
compaction equipment shall be used where use of heavier equipment is
impractical or restricted due to weight limitations.
D. The following compaction requirements shall be in accordance with ASTM D 1557
except for free draining materials (i.e., Coarse Bedding Material /Drain
Rock /Foundation Material), which shall be in accordance with ASTM D 4253 and

amount of wrinkling or folding prior to the sealant cooling and losing tackiness.
When asphalt emulsions are used, the emulsion shall be allowed to cure
properly, essentially with no moisture remaining prior to placing the geotextile
and overlay. Wrinkles or folds in excess of one (1) inch shall be slit and laid
flat. All transverse joints and slit folds or wrinkles shall be shingle - lapped in the
direction of the paving operation. Brooming and /or pneumatic rolling will be
required to maximize geotextile contact with pavement surface. Additional
hand - placed sealant material may be required at laps and repairs as
determined by CCCSD and /or the local jurisdiction.
Section 15.02275 — Geotextile Fabric Page 145
B. All areas with fabric placed shall be paved the same day. No traffic except
necessary construction equipment and emergency vehicles shall be allowed to
drive on the fabric. Turning of the paver and other vehicles shall be done
gradually and kept to a minimum to avoid movement and damage to the
geotextile. Abrupt starts and stops shall also be avoided. Damaged geotextile
shall be removed and replaced with the same type of geotextile, and the
overlaps shall be shingle - lapped in the direction of paving. Overlaps shall not
exceed six (6) inches.
3.6 PLACEMENT OF OVERLAY OR TRENCH PATCH
A. All areas in which fabric has been placed shall be paved during the same day.
The temperature of the hot mix shall not exceed three hundred twenty five
degrees Fahrenheit (325 °F). Sealant bleeding through the geotextile shall be
removed. Excess sealant can be removed by broadcasting hot mix or sand on
the fabric. Excess sand or hot mix should be removed before beginning the
paving operation. In the event of rainfall on the fabric prior to the placement of
the asphalt overlay, the fabric must be allowed to dry completely before asphalt
is placed. This will prevent the trapping of water (steam) under the hot asphalt
that could induce cracking.
B. Asphalt concrete pavement shall be placed over the geotextile fabric to a
minimum thickness of two and one half (2 -1/2) inches or the thickness required
by the local jurisdiction, whichever is greater in accordance with the
requirements specified in Section 15.02515 - Asphalt Concrete Pavement and

pounds per square inch (psi). After the air supply is securely turned off or
disconnected, there shall be a two (2) minute waiting period to allow
stabilization of air within the sewer line before the actual test period begins.
In no case shall the air pressure within the line be less than three and one -
half (3 -1/2) pounds per square inch at the beginning of the test period. The
allowable air pressure loss shall not exceed one (1) pound per square inch.
When testing sewers up to and including sixteen (16) inches in diameter,
refer to DWG -28 of the Standard Drawings for the length of the test period.
When testing side sewers, or portions thereof, the test period shall be four
(4) minutes and the allowable loss shall not exceed one (1) pound per
square inch. After completion of a test, the air pressure shall be released
slowly through the valve, which is incorporated in the test equipment. Air
test plugs shall not be removed until the air pressure is no longer
measurable.
C. New sewers larger than seventeen (17) inches in diameter shall be hydrostatically
tested in accordance with the following procedure:
After installation, all new trunk sewer pipelines shall be thoroughly cleaned
prior to pressure testing. A section of trunk sewer shall be prepared for
testing between two structures by plugging the inlet side of the discharge
manhole and all openings in the upstream manhole except the discharge
opening. All plugs shall be properly braced against the manhole wall to
withstand the forces of the test in order to prevent loss in the event of a
failure.
2. A section of the trunk sewer prepared as above shall be tested by filling it
with water to an elevation five (5) feet above the top of pipe at the upstream
end of the test section, or five (5) feet above the existing groundwater
elevation, whichever is greater. The water shall be introduced into the test
section at least one (1) hour in advance of the test period and refilled as
necessary prior to commencement of the test period to allow the pipe and
joint material to become saturated. The loss in water may be determined
Section 15.02730 — Pipeline Cleaning, Testing and Televising Page 196
by measuring the rate of fall of the water level, but the level shall not be
allowed to fall more than one (1) foot below the specified head during the
test period.
3. For RCP, the pressure shall be maintained for not less than four (4) hours
and the leakage rate shall not exceed two hundred (200) gallons per inch of
diameter per mile of pipe for twenty -four (24) hours (ASTM C 969 -02). For
VCP, the pressure shall be maintained for not less than one (1) hour and
the leakage rate shall not exceed two hundred (200) gallons per inch
diameter per mile for twenty -four (24) hours (ASTM C 1091 -03a). For DIP,
the pressure shall be maintained for not less than one (1) hour and the
leakage rate shall not exceed seventy (70) gallons per inch diameter per
mile of pipe of twenty -four (24) hours (AWWA C600 -54T).
D. When leakage exceeds the amount allowed by the specifications, the Contractor
shall locate the leaks, submit a repair procedure for the Inspector's review, and
make the necessary repairs.
3.5 TESTING OF MANHOLES
A. CCCSD may require hydrostatic testing for leakage after installation and prior to
backfilling. Prior to hydrostatic testing, all manholes shall be visually inspected.
All defects shall be repaired by the Contractor, with non - shrink grout, to the
satisfaction of the Inspector. All pipes entering the manhole shall be sealed at a
point outside the manhole walls so as to include testing of the pipe /manhole joints.
Safety lines shall be secured to all plugs utilized. The manhole shall be filled with
water to a level two (2) inches below the top of the frame. After a period of at
least one (1) hour to allow the water level to stabilize, the manhole shall be refilled
and the water level shall be checked. The water level shall again be checked after
a period of four (4) hours. If the water level drops by more than one (1) inch, the
leakage shall be considered excessive, and the Contractor shall make necessary
repairs and retest the manhole.
B. As an alternative to manhole hydrostatic testing, the Inspector may allow the use
of vacuum testing. A vacuum of ten (10) inches of mercury shall be drawn on the
manhole, the valve on the vacuum line of the test hood closed and the vacuum
pump shut off. The manhole shall be deemed to have passed the test if the
vacuum drop is less than one (1) inch of mercury during a one (1) minute test
period.
