SUBMITTED BY
ISSUE: Two vehicles were authorized in the 1982-1983 Equipment Budget for the CSO
Department, staff work has been completed, and we hereby recommend to the Board that
the purchases be approved.
BACKGROUND: Formal public bidding started August 6, 1982 with bid opening on August 26,
1982. Nine bids were received.
A commercial and technical evaluation was conducted by Purchasing and CSODepartment.
This joint evaluation showed that the following bidders meet all District criteria and
are under the approved dollar limitation of the Equipment Budget.
OSun Valley Ford was lowest responsible bidder for the 10,000 lb. GVW cab
and chassis at $8,968.66.
OAvery Green Motors was lowest responsible bidder for the 24,000 lb. GVW, diesel,
cab and chassis at $22,940.47.
These vehicles will have dump bodies installed on them. The 10,000 lb. GVW cab and
chassis will be fitted with the Districts existing dump body, which will be reconditioned
then mounted. The 24,000 lb. GVW cab and chassis wi.ll require a new dump body since the
old bed is beyond reconditioning. The new dump body is estimated to cost less than $5,000
installed.
It is our intention to separately bid the new dump body to assure the best equ,ipment
and competitive prices are obtained.
RECOMMENDATION: Award purchase orders to Sun Valley Ford for the 10,000 lb. GVW cab and
chassis at $8,968.66 and to Avery Green Motors for the 24,000 lb. cab and chassis at
$22,940.47.

ISSUE: On Sept. 29, 1982 sealed bids for District Project No. 3644
were received and opened. The Board of Directors must award a
contract or reject proposals within 30 days of the opening of sealed
bids.
BACKGROUND: On April 15, 1982 the Board of Directors authorized funds
for design of storm damage repairs to the collection system. Erosion
of a steeply sloping hillside during winter storms caused a portion of
our 6-inch sewer main near Leland Drive, Lafayette to be displaced.
CSO Department has taken all emergency measures required to keep the
system in operation.
Plans and specifications for the project (DP 3644: 1981-1982 Storm
Damage Repair to EX (6"-XI552) Leland Drive. Lafayette) were completed
and advertisements inviting submission of sealed bids were placed on
September 7 & 14, 1982.
Six bids ranging from $11,599.00 to $28,262.00 were received (see
attached tabulation). The apparent low bidder is: Overmiller, Inc.,
dba Roto-Rooter Service/B&J Sewer Contractors of Walnut Creek,
California. The Engineer's estimate for the work was $12,000.00. A
Post-Bid/Pre-Construction cost estimate is attached. $17,200.00 is
needed to complete the project including contract construction,
construction management, incidentals and contingencies. Federal
Emergency Management Agency (FEMA) grant funds will be available to
reduce the Net Project Cost to the District. An estimate of this
funding is noted in the cost estimate referred to above.
RECOMMENDATION: Award the contract for construction of District
Project No. 3644 to Overmiller, Inc., dba Roto-Rooter Service/B&J
Sewer Construction per their bid received on Sept. 29, 1982 and
authorize $17,200 in sewer construction funds for contract construction,
construction management, incidentals and contingencies.

AUTHORIZE GENERAL MANAGER-CHIEF ENGINEER TO EXECUT
A CONTRACT FOR A PRIVATE BRANCH EXCHANGE TELEPHONE
SYSTEM AND AUTHORIZE FUNDS NOT TO EXCEED 49 500
SUBMITTED BY
Paul Morsen, Administrative Dept. Manager
ISSUE: A telecommunication system is required for the District's new Headquarters Office
Bui Iding. A contract must be executed with the selected supplier of the Private Branch
Exchange (PBX) system in sufficient time to assure installation of an operational system
coincident with building occupancy.
Authorize Contract
Execution and Funds.
BACKGROUND: Staff members of the Engineering and Administrative Departments began
preparation of the specifications for the PBX system and the Request For Proposal in early
1981. Because of the rapid pace of technological advancements in telecommunications, a
number of potential suppliers were contacted during the initial requirements definition phase
of the project to insure that all relevant technical issues would be addressed in the Request
For Proposal. Funds were authorized by the Board of Directors in November 1981 for a
comprehensive review of telecommunication requirements and preparation of the final
system specifications.
As a result of the review, a system design was determined in consideration of the following
criteria:
o
o
o
o
To obtain a system with advanced technological design to maximize future
flexibility.
To minimize maintenance expenses and problems.
To minimize the number of telephone stations.
To provide Plant Operations and Collection System Operations Departments with
expense reduction features of the new system.
To maximize the use of existing telephone instruments.
To provide expansion capability to meet future telephone requirements.
To evaluate all optional features of the system on the basis of cost effectiveness
only.
To provide for emergency communications and operational requirements of the
Plant Operations Department.
o
o
o
o
( A Schematic of the Proposed System is attached on the following page)
The continuing telecommunications requirements of the Collection System Operations (CSO)
Department in the Walnut Creek Office subsequent to occupancy of the new Headquarters
Office Building were considered in the system design. The Board of Directors has previously
been advised that the Walnut Creek Office is intended to undergo interior restructuring to
meet long-standing space requirements of the CSO Department and to convert excess office
space for leasing. The District's presently leased Walnut Creek Office PBX system, which
will be acquired by exercise of a lease purchase option in late 1982, will be modified to serve
the requirements of the CSO Department and the leaseable office space. The CSO

Department portion of the system will be connected to the PBX system in the Headquarters
Office Building to realize expense reduction features of the new system.
The new PBX system will have a small increase in the number of telephone stations as
compared to the present system (138 vs 132). The new system wi II include features for
expense reduction in long distance and East Bay/San Francisco exchange calls. Accountabil-
ity for toll calls by originator will be provided for cost accounting and control. The system
requirements provide for maximum telephone reception and message distribution efficiency.
Service and maintenance commitment and responsiveness, as well as proximity of service
personnel and facilities, were considered to be of paramount import; accordingly, response
time and personnel experience and training requirements were included in the specifications.
Requests For Proposals were distributed to seventeen prospective suppliers on July 23, 1982.
Eleven proposals were received. The proposals were reviewed by two members of the
selection committee to determine compliance with the technical and contractual requirement
contained in the Request For Proposal. During the review, six proposals were found not in
compliance with minimum requirements.
The five proposals selected for further consideration were distributed to each committee
member for independent review. In addition to technical criteria, the following additional
comparative measures were evaluated: purchase price; lease price and terms; price of
options; maintenance expenses; service response time; location of service personnel; remote
diagnostic capability and training of District personnel.
The results of the committee members' evaluations were reviewed by the committee as a
whole. Suppliers were contacted by telephone to obtain proposal clarification. A number of
PBX systems were visited by committee members to observe proposed and other systems in
operation. Customer references of each supplier were contacted. The evaluation of the
committee is summarized in the Analysis section which follows.
ANAL YSIS: The PBX system proposed by each of the five suppliers were evaluated based on
technical requirements specified by the District. Each supplier was determined to meet the
minimum requirements of the specifications, with technical exceptions being acceptable and
not detrimental to the functional operation of the system. The suppliers were ranked, based
on the technical requirements, in descending order as follows:
I) Pacific Telephone & Telegraph Company
2) Northern Telecom, Inc.
3) Star Datacom, Inc.
4) Mall Telecommunications
5) Harris Digital Telephone Systems
Pacific Telephone and Telegraph Company, Star Datacom, Inc. and Harris Digital Telephone
Systems were completely responsive to the District's requested contractual terms and
conditions; Northern Telecom, Inc. and Mall Telecommunications deviated from the requested
provisions in a number of respects.
Attachment I summarizes certain salient features of the system proposed by each supplier.

Pacific Telephone and Telegraph Company is prohibited under its present tariffs to offer its
telecommunication systems on anything but a leased basis. The other four suppliers proposed
their systems on a purchase or lease purchase option. Attachment II summarizes the
purchase costs, monthly lease expense, monthly maintenance expense, cumulative lease costs,
and their discounted values, for each supplier.
In order that the lease purchase costs of the proposed systems be comparative, monthly
maintenance expenses beginning in the second year are required to be added to other
supplier's lease purchase costs, as maintenance services are included in the lease costs of
Pacific Telephone.
The results of the cost comparison summarized on Attachment II are presented below:

The cumulative lease and maintenance expenses over the lease term, and the discounted
values to restate such expenses in current dollars, as well as the purchase cost and purchase
cost plus the discounted value of cumulative maintenance expenses are indicated for each
supplier. While Pacific Telephone does not presently sell its systems, changes in its
marketing policies may occur in 1983 as a result of the American Telephone & Telegraph
Company divestiture agreement.
Pacific Telephone's present policy of leaving its system exclusively and its higher cumulative
lease and maintenance expenses compelled evaluation of the leasing' or purchasing alterna-
tives. It was the committee's conclusion that superiority in equipment characteristics and
maintenance support and training, as well as the avoidance of technological obsolescence in a
rapidly changing environment, were critical considerations.
CONCLUSIONS: No other item of equipment to be acquired for the Headquarters Office
Building will have as critical a long-term importance in the effective conduct of the
District's business as wi II the PBX system. The PBX system wi II be used during each work
day by virtually every staff member for internal communication and contact with business
associates and the public. Because of its pervasive impact on District operations, the
selection committee considered it essential that a supplier of a telecommunication system
which would provide a reasonably long-range and stable relationship be selected. Accord-
ingly, the system proposed by Pacific Telephone and Telegraph Company is being recom-
mended.

It is evident from the financial analysis that the Pacific Telephone system is not the least
costly in terms of apparent cost, although every effort has been made to minimize system
cost through avoidance of unnecessary stations and features and by making maximum use of
existing equipment. The following compelling reasons, however, were the bases for the
committee's recommendation:
Future Flexibility - Because of its modular design, the system permits a variety of line
and trunk combinations and simplifies future expansion. The addition or removal of
equipment features and stations as well as incorporating new technology can be
accomplished easily. If so determined at a future date, the lease may be terminated
and the system replaced by another after one year. All other suppliers required a three
to five year minimum lease period.
Supplier Reliability - Pacific Telephone has been in operation since 1906 and it is
unlikely that any major interruption of service would occur because of bankruptcy, a
change in corporate marketing policies or other unforeseen circumstances. Should a
portion or all of the PBX system be destroyed as a result of disaster, negligence or wear
and tear, affected equipment is replaced free of charge. All specifications and
requirements under Pacific Telephone's proposal will be assumed by the successor
company established by American Telephone and Telegraph Company.
Cost Effectiveness - Expense reduction features of the system include selection of
optimal long distance modes and providing accountabi Iity and control. A customer
administration panel permits changes to the system by trained District personnel, thus
avoiding $300-$400 charges per service call usually required for other systems.
Training programs before and after cutover are provided without additional charges.
Maintenance Support - Pacific Telephone service includes preventive and remedial
maintenance for the life of the contract. The maintenance program is extensive and
includes continuous internal routine maintenance within the system, remote diagnostics,
disaster recovery, and an extensive maintenance support organization.
Training - Pacific Telephone will provide complete training before and after cutover in
the use of the system. Special in-depth training will be provided to one or more
employees designated as Communication Counselors.
For the foregoing reasons, the committee believes it to be in the District's best interests to
select Pacific Telephone to furnish the PBX system for the Headquarters Office Building.
Attachment III presents a summary of funds now required for the PBX system.
RECOMMENDATION: Authorize the General Manager-Chief Engineer to execute a contract
with Pacific Telephone and Telegraph Company for a PBX system, and authorize funds for
design and installation costs not to exceed $49,500.

INITIATING DEPT./DIV.
Construction and Services Division
ISSUE: The property owners, Richard Todoroff, et ux, desire to maintain in place,
a carport which was erroneously constructed over a District easement.
BACKGROUND: In April of 1981, the District1s Collection System Operations Department
became aware of a damaged sewer main within the above mentioned District easement.
The damage was repaired at District expense. After negotiation between all parties
involved, it was agreed that Founders Title Company would pay the District's costs
of $3,039.05.
Staff has determined that the carport will not interfere with the operation of our
sewer. The subject agreement makes the property owner responsible for additional
maintenance costs which could result from the encroachment of the carport.
RECOMMENDATION: Approval, execute "Agreement" and authorize its recording.

ISSUE
Funds must be authorized to allow the multiple hearth furnace renovation
project to proceed. Authorization is required for the General Manager-
Chief Engineer to execute a contract for professional engineering services
with Malcolm Pirnie, Inc.
BACKGROUND
,
Two multiple hearth furnace (MHF) systems were installed at the treatment
plant to recalcine lime and to incinerate sludge prior to disposal as part
of the Stage 5A Project. Several attempts were made by the contractor to
place the MHFs in operation; however, the contractor did not achieve suc-
cessful operation prior to dismissal in 1979. The MHFs were mothballed
and the District engaged Metcalf & Eddy and Malcolm Pirnie, Inc. to provide
professional engineering services for making the MHF systems operational.
Engineering activities have included facilities planning in light of
changed discharge requirements, establishing the current condition of the
equipment, identifying required repairs/modifications, and preparing a plan
of action to place the MHFs into operation.
Since 1976, dewatered sludge from the treatment plant has been landfilled
. at Acme Fill. Disposal of unstabilized sewage sludge is in violation of
~'-'...::.> state 'law; however, the Regional Water Quality Control Board issued a
waiver~for an indefinite period to allow the treatment plant to operate
until the District can meet the stabilization requirement. Four methods
of sludge stabilization, including anaerobic digestion, composting, and'
lime stabilization, were evaluated during Facilities Planning. Inciner-
ation was identified as the least costly method of sludge stabilization
even after the treatment plant is converted to a conventional secondary
process.
Work by both Metcalf & Eddy and Malcolm Pirnie has shown that while
construction of the MHF systems is essentially complete, both repairs and
modifications are required prior to long term operation. Furthermore,
testing is required to demonstrate whether or not the existing air pol-
lution control equipment can meet the current regulations.

The possible wor~t case cost estimate for all four phases is $4,600,000
as detailed in Attachment A. A better estimate of the total project cost
will be available upon the conclusion of Phases I and II. The Board is
being asked to authorize $1,875,000 for Phases I and II at this time.
Funding for Phases I and II is anticipated from the following sources:
Stage 5A Settlement
Stage 5A Project Completion Grant
$ 400,000
255,000
$1,220,000
$1,875,000
CCCSD
To ta 1
The benefits associated with the proposed project include a reduction in
the cost of sludge disposal, a reduction in the cost of steam production,
the ability to stabilize sludge prior to disposal in compliance wit~ State
law, and the effective use of $18 million worth of currently idle facilities.
The annual savings associated with using the MHF instead of landfi11ing raw
sludge is estimated to be $650,000.
Malcolm Pirnie, Inc. will provide design and field assistance during the
start-up and testing (Phase 1) and they will provide design services in
conjunction with Phase II. A contract has been negotiated with Malcolm
Pirnie at a not to exceed cost of $444,750.
This project is included in the 5~year Capital Expenditure Plan as part of
the Stage 5A Project Completion Project.
RECOMMENDATION:
Authorize $1,875,000 from sewer construction funds for Phases I and II
for the renovation of the MHF systems and authorize the General Manager-
Chief Engineer to execute a contract with Malcolm Pirnie, Inc., for
professional engineering services in conjunction with the project.
