Romero, Public Works Director . Prepared by: Lane Wilson, Parks & Buildings Manager T. Tom Harrington, Energy Coordinator-" °OO���CCC"'"' Q Subject: Swim Center Improvement CIP - project priorities, funding, and Hi-Rate Filtration System plans and specifications. C.A.O. RECOMMENDATION: 1. By motion, approve Alternative 1 for reprioritization and funding of CIP Swim Center Improvement Projects, in order to fund the Hi-Rate Filtration System in FY 1991-92 as previously directed by Council. 2 . By motion, approve plans and specifications for "Swim Center Improvement Project, Media Hi-Rate Filtration System, " City Plan No. S-24X, and authorize soliciting of bids and contract award by the CAO, if the lowest responsible bid is within the Engineer' s cost estimate. DISCUSSION Reprioritization The CIP Item for "Swim Center Improvements" includes six distinct projects that were proposed to be constructed in FY 1991-92 (Pool cover replacement, $15, 000; Alarm system replacement, $36, 000; Tot pool dressing room $28, 000; and bank stabilization $30, 000) and FY 1993-94 (High-rate sand filtration, $84, 000; and Ozonation equipment $27, 000) During review of the draft budget, Council indicated that these projects should be reprioritized to complete the filtration and ozonation projects earlier than proposed. The funds appropriated for FY 1991-92 ($109, 000) and planned for FY 1993-94 ($111, 000) did not reflect changes in priorities. In response to the comments from City Council the recommended order of priorities is: 1. Pool cover replacement project $10,948. 08 (completed) Annual savings are estimated to be $40, 000 per year in water, natural gas and chemicals 2 . High-rate sand filtration $84, 000 This project is eligible for a PG&E rebate of $6, 077 and will save $17, 000 annually on the cost of water, electricity, chemicals, filtering materials and labor. This project is ready to go to contract. 3 . Alarm system replacement $36, 000 This is an important project in terms of Swim Center Security. The current alarm system is over 10 years old and is no longer -/4-tl �,rx���{villll►,IIIP10 IIIIIII city Of San _.J1S osispo COUNCIL AGENDA REPORT Swim Center Improvement Page 2 I reliable resulting in numerous false alarms. Design of this project could be completed by the end of summer. 4 . Ozonation equipment $27, 000 With ozonation Public Health standards can be met with less chorine. This will improve the quality of water and will reduce the amount of chlorine needed at the Swim Center. Ozonation will reduce operating costs approximately $1, 200 annually. Development of plans and specifications is in the very early stages. In addition to this project there is a need to modify the Swim Center to contain a leak within the room or cabinet where the chlorine is stored. The Uniform Fire Code, 1988 edition, M.C. 15.08.010 was modified since the Swim Center was constructed. Reducing the amount of chlorine on site will reduce the size of '. the containment facility. The amount of chlorine needed on site and the scope of the containment facility will be defined along with the design on this project. A request to modify this project or to establish an additional CIP project will be submitted when the need is defined. The Fire Department concurs that this project is needed ("the sooner the better") . 5. Tot pool dressing room $28, 000 This project is proposed in order to provide separate changing areas for parents with very young children. Plans are complete ; and specifications are about complete. 6. Bank stabilization $30, 000 The banks on which the solar collectors are mounted are not protected. Although this needs to be accomplished soon, in order to assure the operation of the collectors, this is the lowest priority of the six projects. i This listing gives priority to cost avoidance, safety and security. Fundinc After the projects are reprioritized, the funding for each fiscal year must be established. Either of two alternatives would be appropriate. I Alternate 1 The simplest change would be to accept the priorities and use the existing funding. This does not fully respond to the previous instructions of Council. The Projects would be scheduled as follows: 1991-92 Pool cover $11, 000 High-rate sand filter 84, 000 design work on some. of the following projects 3 . 000 $ 98, 000 ,I i�'e►ilfillll!�Ij II1u II�U� city of San t. .3 OBISPO NNGS COUNCIL AGENDA REPORT Swim Center Improvement page 3 1993-94 Alarm system replacement $36, 000 Ozonation equipment 27 , 000 Tot pool dressing room 28, 000 Bank stabilization 30, 000 $121. 000 Three Year TOTAL $219, 000 Alternate 2 The priorities would be in the order recommended above. Funding would be accelerated by an increase of $77, 000 in FY 1992-93 . The FY 1993- 94 CIP program would be reduced by the same amount. This provides substantial public safety benefits as well as significant operating cost savings. The schedule would be as follows: 1991-92 Pool cover $111000 High-rate sand filter 84, 000 design work on some of the following projects 3 , 000 $ 98, 000 1992-93 Alarm system replacement $36, 000 Ozonation equipment 27, 000 Tot pool dressing room 28 , 000 I $ 91, 000 1993-94 Bank stabilization $ 30 , 000 Three Year TOTAL $219, 000 Filtration Proiect Both alternatives provide for the upgrade of the filtration system during the current fiscal year. The project is ready to go to bid. Replacing the diatomaceous earth filters with rapid rate sand filters j will provide higher levels of filtration at lower costs. The increased filter capacity is also required to support the ozone system which will be the second. part of the filtration and sanitization improvements. The life expectancy of the new filtration system is 20 years. Operational cost savings and a PG&E rebate are expected to repay the investment within five years. The savings include: Electricity savings of 101, 000 KWH per year. The new filters accomplish the task with fewer hours of operation. ($9, 116 annually, non-escalated 1992 dollars) A PG&E rebate of $6, 077 . 52 if the project is completed by June 1992 . Pump repairs will be reduced by $700 per year because pumps will be operated fewer hours. Annual replacement of filter elements and media will be eliminated resulting in a savings of $6, 500 annually. Cit-3 CI ty of sar.__ais OBISPO COUNCIL AGENDA REPORT Swim Center Improvement page 4 i Overtime will be reduced by $300 per year as the new filters can be cleaned while the pool is in operation. The final result will be a cleaner pool for less money. FISCAL IMPACT Reprioritization In light of the City's current financial situation, staff recommends Alternative 1 in order to stay within the funding planned in the FY 1991-93 Financial Plan. Alternative 2 would spend the $77, 000 one year earlier than projected in the Financial Plan. Total expenditures between now and the end of FY 1993-94 would be the same for either alternative. Filter Replacement Project Engineer's Cost Estimate 84, 000 without contingencies Funding in the amount of $84, 000 is included in CIP Swim Center Improvements (FY 1991-93 Financial Plan pages E-9 and E-20) . The reprioritization of the six distinct projects within this CIP provides for funding this project from the $109, 000 appropriated in FY 1991-92 .
