COLETTE CURTIS-BROWN
SUBJECT: JUNE 28, 2004 FINANCE COMMITTEE QUESTIONS
Eight inquires were made at the last Board Finance Committee meeting that required
subsequent staff research. The questions and answers are provided below:
1. Page 6, 150641 Danaher Power Solutions 3Year Maint. Contract (Mario/Parke)
What type of maintenance contract and what for?
The contract is for preventive maintenance for the Cyberex UPS (Uninterrupted Power
Source), which is used to keep critical plant equipment up and running in case of power
failure. Danaher is a sole source. They are the only authorized service agents and are
also the manufacturer of the equipment. The contract is for three years at a cost of
$9,870. There are cost savings by purchasing amulti-year contract. The cost for one
year is $3,500, so the three-year savings is $630. The coverage under the contract
calls for one preventive maintenance visit per year and all travel expenses are included
in the contract cost. Coverage under the contract also provides for unlimited access
(24 hours/day, 7 days/week) to factory-trained representatives, a 10% discount on
spare parts and a 33% discount on hourly service rates (the rates we would pay on a
time and materials basis without a service contract). We also have priority scheduling
for remedial and emergency work.

Please obtain the product sheet listing chemical composition.
The product information requested is attached to this memo.
3. Page 7, 150662 J.T. Thorpe & Son, Inc. Furnace Repair (Mario)
What was the furnace repair?
This was furnace refractory brick maintenance and repair. It is the annual maintenance
performed on the furnace due to normal wear and tear.
4. Page 8, 150672 National Elevator Co. Elevator Repair (Parke)
HABudgeffludget and Fin Comm Responses 6 28 04.DOC
What routine maintenance is performed and when is it scheduled? How many
elevators are at the District and does the same company perform routine and
corrective maintenance on all of them?
The maintenance is performed monthly. We have four elevators and two dumbwaiters
(Administrative passenger, Administrative dumbwaiter, Solids Building freight, Solids
Building passenger, Machine Shop freight, and POD dumbwaiter). National Elevator Co.
inspects all of our elevators. The technician first rides in the elevator to check for leveling
or ride problems. The technician gets underneath and on top of the elevator to perform
their inspection. The equipment room is also inspected and maintained. Roller guides are
checked, equipment is lubricated as needed, oil levels are checked, motor and generators
are inspected, the brakes and brake shoes are checked, door operators, drive belts, chain
drives, and all safety items are checked and inspected.
5. Page 9, 150687 Polydyne, Inc. Chem/Clarifloc (Mario)
What is this material used for, what does it do? Routine? How much is used in a
year's time?
Polydyne is the supplier of polymer (flocculent) used in the centrifuge sludge
dewatering process. It is a very critical chemical required to ensure proper operation of
the centrifuges and consistent operation of the multiple hearth furnace. Polymer is a
high molecular weight, high molecular charge, long-chained organic compound which
causes the sludge to flocculate and dewater effectively. The amount of use varies with
the condition of the sludge and its use can greatly increase during plant upsets.
Fortunately the plant operation is reasonably stable and thus the use of polymer has
been relatively consistent. We use about two million pounds per year at a cost of
$0.08/Ib or around $175,000 /year. We also use polymer in the filter plant to improve
the filtration process but it is a different product supplied by a different manufacturer.
We periodically test different polymers at both sites to ensure that we are achieving the
lowest cost of operation.
6. Page 18 150766 Water Environment Research Membership (Mario)
What do we get from our membership, value? Are we taking full advantage of
our membership?
Please see the memo and attachment from Jim Kelly, Director of Operations.
7. Page 20, 26794 Dell Marketing Proj/PH Rel Int Ph5 (Parke)
What did we buy for the project from Dell?
We purchased a fast new computer and twin flat panel monitors to replace a very old
computer with a small CRT monitor used by Kelly Weir in the Survey Field Office. Kelly
does most of our raw data processing and needs the additional power to work effectively.
A graphics card and twin flat panel monitors were purchased for use in the HOB Survey
Office. Posting related digital documents and maps side-by-side while doing legal analyses

is more efficient and less prone to error than shuffling through piles of paper. We are using
the new equipment in connection with a redesign of Pleasant Hili Relief Interceptor 5 as
well as deed and easement work for the project. Of course, the monitors will also be used
for other tasks, but the computer equipment was purchased by the project so that
complex work could be done quickly during construction.
8. Page 22, 25812 Crossroads Right of Way Projects (Parke)
What was done and why?
In January 2803 staff reviewed RFP's and interviewed right of way consultants to assist in
appraising and acquiring right of way for District Projects. Crossroads RAN Inc. was one of
five firms selected to provide right of way services to the District. Some of the projects the
firm has worked on are the Lafayette Renovation Project, Walnut Creek Renovation
Project, Pleasant Hill Road East Project, North Main Street Walnut Creek Project, South
orinda Phase II Project, Vessing Road Project, and others. The tasks included researching
existing easement rights, acquiring new easements, and assisting staff in researching title
issues pertaining to District owned property.

FROM: JIM KELLY
SUBJECT: FINANCE C MITTEE QUESTION REGARDING THE WATER
ENVIRONMENT RESEARCH FOUNDATION
The (Nater Environment Research Foundation (WERF) is a not-for-profit 50'l(c)(3)p
organization that funds and manages water quality research for subscribers such as
Central San through a diverse public-private partnership between municipal utilities,
,
corporations, academia, industry, and the federal government.
WERF has a research portfolio valued at nearly$50 million with more than 200
completed and ongoing research projects. It serves as the research arm for more than
250 subscribers at a time when the water quality communityis under pressure to reduce
spending. Local municipal wastewater and storm water agencies in 40 states,
representing some 70 percent of the sewered U.S. population and several agencies in
other countries, support WERF through their annual subscription fees.
U.S. and global industry, major wastewater equipment manufacturers, vendors
operators, and consulting firms arealso subscribers. More than 375 organizations in 42
„ 9
states and several countries participate as contractors, sub-contractors, and test sites or
contributors to research projects. This coverage ensures that subscriber priorities are
addressed, that local implementation is inherent in all what WERF does, and that the
recognized subject matter experts are used to work on the most critical waterualitY
problems.
q
WERF maintains an unbiased and competitive contractor selectionrocess stringent
p g
quality control measures, and a nationally recognized technical peer review process. As
.
a result, its research is a trusted resource that is used widely for regulatory, water
quality, science policy, and management decisions. WERF typically Y funds near! $7
million in new projects each year.
With the support of subscribers, funding from the federal government, and partnerships
with other organizations (both in the United States and
abroad), WERF generates
timely, relevant research at a fraction of what it would cost individual subscribers to
conduct the same research. WERF maximizes the investment made b each subscriber

that result in an additional 33 percent research program funding. Central San has
directly benefited through several WERF projects, such as the ultraviolet (UV)
disinfection and furnace emissions research efforts that enable us to have good design
g
information for our UV system and to continue to have appropriate emission regulations
for our furnaces. For your information and use, I have attached the most recent WERF
publication, which highlights some of WERF's current research efforts. Please call me if
you need any further information.
