SUBMITTED BY

Plant Operations/Maintenance
Issue: On October 18, 1983, sealed bids for cleaning out Alum Sludge Basin I,
located at the District's Water Pollution Control Plant, were opened. The
Board of Directors must award a contract or reject proposals within 30 days of
the opening of bids.
Background: The Central Contra Costa Sanitary District continues to treat alum
sludge generated by the Contra Costa County Water District through the use of
settling/drying basins on the Water Pollution Control Plant site pending the
resolution of the alum sludge issue. At present the second of the two alum
sludge settling/drying basins is full, dried, and requires cleaning; the other
alum sludge basin was cleaned last year and is now in use. Approximately 10,500
cubic yards of dried alum sludge will be banked in a disposal area on site.
This contract does not provide for off-site disposal of the alum sludge. Based
on last year's contract cost, the engineer1s estimate for this contract is
$60,000. A Sewer Construction Fund Account will be established for this work to
track costs and to recover costs from Contra Costa County Water District.
This project was advertised on October 9, 1983, inviting contractors to review
the project and submit sealed bids within ten days. Bids were received ranging
from $35,700 to $252,000. The apparent low bidder is Winton Jones.
Keen interest and a close geographic location allowed the contractor to bid
below the engineer's estimate.
Recommendation: Award the contract for the cleaning of Alum Sludge Basin I to
Winton Jones per their bid and authorize $41,000 in Sewer Construction Funds
for construction, contingencies, and incidentals.

The lowest Bidder is Winton Jones. They have previously performed contract
work for the District and demonstrated that they can fulfill all of the
requirements of a contract. Winton Jones' bid is below the engineer's
estimate of $60,000. Purchasing, therefore, recommends that you prepare

Dennis R. Hall
INITIATING DEPT./DIV.
Construction and Services Division
SUBMITTED BY
ISSUE: The District must pass a resolution to final ize the annexation of the
above-referenced annexation.
BACKGROUND: The property owner, Mr. Jerome Magee, made application to the Local
Agency Formation Commission for the annexation of one parcel of land designated as
District Annexation 84. The annexation was initiated with L.A.F.C. because the
property is outside the District's Sphere of Influence (SOl) boundary.
On August 10, 1983, L.A.F.C. held a hearing to consider the application. L.A.F.C.
determined that the annexation was categorically exempt from environmental review.
L.A.F.C. approved the annexation and the amendment of the District SOl to include
the annexed territory. Pursuant to Government Code Section 56261, the District
was authorized to proceed with the annexation without notice and hearing.
RECOMMENDATION: Adopt a resolution ordering the completion of District Annexation
No. 84 in compl iance with L.A.F.C. Resolution 83-14 which was passed and adopted
on August 10, 1983.

ISSUE
Funds are required for the design and construction of a relief sewer to
prevent surcharging of a 30" trunk sewer in Walnut Blvd., Walnut Creek,
during wet weather.
BACKGROUND
The 30 inch diameter trunk sewer flowing north in the old Sacramento
Northern right of way in Walnut Creek (shown on Attachment A), is
flowing full during wet weather. It parallels a 60 inch diameter trunk
sewer that is flowing partially full. The high flows in the 30 inch
diameter sewer are causing the two 18 inch diameter sewers in Walnut
Boulevard to surcharge.
The proposed project entails installing an overflow structure that
would allow the smaller trunk sewer to discharge excess flows to the
larger trunk sewer.
Design work has been completed by the Engineering Division using Sewer
Construction Funds authorized by the General Manager-Chief Engineer.
The construction work will be accomplished by Collection System Opera-
tions Department. A cost estimate is included on Attachment B.
RECOMMENDATION
Authorize $9100 from Sewer Construction Funds for the design and
construction of DSP 3914, Walnut Blvd. Relief Sewer.

A CONTRACT WITH LOWRY & ASSOCIATES FOR A PLANNING AUTHORIZE CONTRACT

INITIATING DEPT./DIV.
Engineering Division
SUBMITTED BY
John A. Larson
ISSUE: A planning study is needed at this time to identify the collection system facility needs
resulting from growth in and around the San Ramon Valley. Board of Directors' approval is
required for the General Manager-Chief Engineer to execute a contract for professional
services.
BACKGROUN): Collection system facilities planning has been accomplished by the Engineer-
ing Department in recent years by a combination of watershed planning and sewer design. The
increasing rate of growth in the southern area of the District coupled with advances in the
state-of-the-art of computer-based planning have dictated a new approach to collection system
facilities planning.
Growth within the San Ramon Valley is proceeding rapidly and a major planning effort is
required at this time to provide for the orderly design and construction of facilities necessary
to accommodate this growth. Two developments will have far reaching effects: The Bishop
Ranch Office Park and Oakcreek (Kaplan-Wiedeman). In addition, the Tassajara Valley has the
potential for additional development and the Dublin San Ramon Services District is conducting
a study which identifies the Central Contra Costa Sanitary District Wastewater Treatment
Plant as one alternative for its future sewage disposal capacity needs.
The District has performed a wet weather metering study which confirms that the San Ramon
Valley Collection System has the capacity to accommodate growth in the near term. However,
it is time to initiate a comprehensive collection system facilities plan for the San Ramon
Valley.
A planning study is proposed that will encompass the area shown on the attached map. The
study wi II have a broader scope than recent watershed studies and wi II include the following
work:
o Detailed facilities planning for Danville, Alamo, San Ramon, South Walnut Creek and
Sycamore Valley watersheds 33, 34, 35, and a portion of watershed 29 including
facilities required within five years and ultimate facilities at "build-out."
o Updated watershed fees within the study area.
o Design information for a bypass around downtown Walnut Creek to be built in
conjunction with the proposed Corps of Engineers San Ramon Creek bypass project
o Facilities requirements associated with serving portions of the Tassajara and Liver-
more/ Amador Valleys at various levels of growth, and
REVIEWED AND RECOMMENDED FOR SOARD ACTION
INITIATING DEPT ..'DIV.
A
VL
JAL
o Information for use in assessing the adequacy of the current collection system design
criteria.
The planning study approach is consistent with previous sewerage system studies conducted in
1956 and 1966 in that the watersheds with simi lor growth scenarios and/or sharing downstream
facilities are evaluated concurrently.
The proposed project team consists of District staff, the consulting firm of Lowry and
Associates, and the flow monitoring specialist, American Digital Systems. District staff would
be responsible for project management. Lowry and Associates was selected for their
experience in collection system planning. They wi II develop growth scenarios for District
review, evaluate facility requirements using the computer model, and prepare a report. Use of
the Lowry computer program for facilities planning has the following advantages:
o Flow monitoring will allow a computer model calibration that will make sewer sizing
much more accurate than was achievable in the past
o The computer program can be rented in the future to perform local capacity studies,
thus saving repetitive future work
o The District will have the opportunity to purchase the computer program for possible
in-house use for future collection system planning studies after the program's
usefullness is evaluated.
It was decided to use a consultant for the facilities planning effort because District staff time
is committed on other high priority projects and because of the availability of an "on-the-shelf"
computer program. American Digital Systems was chosen for flow monitoring because they
have developed a sewer flow monitoring system that is reliable, accurate, and relatively
inexpensive to use.
The cost of the planning study is estimated to be $48,600 as outlined in the attachment. Funds
for the planning study would come from the watershed accounts as previously authorized. The
study will take approximately four months to complete.
RECOMMEI\DATION: Authorize General Manager-Chief Engineer to execute a contract with
Lowry and Associates for a planning study in the San Ramon Valley at a cost not to exceed
$37,000.
