Item #9 CITY OF COLTON AGENDA REPORT For Council Meeting of October 19, 2004 TO: Honorable Mayor and City Council FROM: Jeannette Olko, Electric Utility General Manager SUBJECT: Request for approval of award of contract to Mohr Power to design and install Solar Pool Heating, Domestic Water Heating, and a new pool heater at the Colton Community Center. DATE: October 14, 2004 BACKGROUND: The Electric Utility is requesting approval to award a contract to Mohr Power to design and install a Solar Water Heating System to help reduce the nearly $27,000 annual natural gas costs to heat the Community Center Swimming Pool and water for showers and other uses. DISCUSSION/ANALYSIS: The Community Center Swimming Pool is used year round and requires water temperature of 82 degrees. A pool heater is used from October through May. The natural gas costs to heat the pool and provide hot water for other uses are nearly $27,000 annually. Staff investigated a variety of options to reduce natural gas costs for pool heating including cogeneration, ground source heat pumps, and solar water heating. Solar water heating was determined to be the most reliable, cost effective, and sustainable method for reducing natural gas consumption. An RFP was issued on August 4, 2004 and a Pre -Proposal Conference was held for all interested vendors on August 11, 2004 at the Gonzales Community Center. On September 8, 2004, two proposals were received and evaluated, and the lower cost of two proposals was selected. The contract will be to design and install a system that will use solar energy to reduce the energy costs of heating the Colton Community Swimming Pool and provide hot water for other uses in the Gonzales Community Center. The contract will also include a new high efficiency, AQMD compliant, gas pool heater that will be used to raise the water temperature in the pool to the desired temperature when weather conditions reduce solar energy for water heating. ALTERNATIVES: 1. Don't heat the swimming pool 2. Continue to pay high costs for heating the pool and also pay the cost installing a high efficiency pool heater. FINANCIAL IMPACT: Funds are available for the energy saving improvements in the Public Benefits account number 520-8000-8039-3890-0107. ENVIROMENTAL IMPACT: Solar water heating and new efficient AQMD compliant pool heater may reduce the consumption of more than 300,000 cubic feet of natural gas and, consequently reducing greenhouse gas and other air polluting emissions.
