ADJOURNMENT 19 Recycled Paper Central Contra Costa Sanitary District July 9, 2004 TO: BOARD FINANCE COMMITTEE FROM: RANDY MUSGRAVES PA 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. 2. Page 6, 150645 Dukes Sales & Service Vapofoam Sewer Lines (Mario) 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 H:\BudgetSudget and Fin Comm Responses 6 28 04.DOC 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.

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 Y through a 3:1 leveraging of federal investment and partnerships with other organizations g S:IAdministrative\Kelly120041WERF Information.doc 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.
