BACKGROUND The City's Sewer Enterprise has been operating and maintaining a wastewater (sewer) collection and pumping system in Pleasanton since the 1920's. The City sewer system currently serves approximately 69,500 residents, representing approximately 19,150 utility accounts or approximately 28,300 dwelling unit equivalents (DUES) as of June 30, 2006. The City's sewer facilities are planned, engineered, operated and maintained through the City's Public Works Department. The Department is responsible for operating and maintaining over 270 miles of sewer pipelines, ranging in size from 6 to 33 inches in diameter, and 10 sewage pump stations that transport the City's sewage to the Dublin San Ramon Services District (DSRSD) wastewater treatment plant. Over half of the flow conveyed to the DSRSD wastewater treatment plant requires pumping. The City contracts with DSRSD to treat its wastewater. Wastewater emanating from the City and DSRSD's sewer service areas is treated at the regional wastewater treatment facilities located in the northwest portion of the City Qust south of the intersection of Johnson and Stoneridge Drives). Following the treatment processes, the secondarily treated wastewater is pumped to the Livermore Amador Valley Water Management Agency's (LAVWMA) facilities where it is pumped westerly to a facility near the San Francisco Bay for disposal. LAVWMA is a joint power authority between the cities of Pleasanton and Livermore, and DSRSD. In addition to the daily operation and maintenance of the City's local sewer collection system, the City's Public Works Department also plans for and develops an ongoing program of replacement and improvements to the local sewer system through the City's Capital Improvement Program. Over the past four years, the City has expended approximately $2.6 million for pipeline replacements, pump station improvements, and other projects, and has projected spending between $4 million and $8 million on required sewer system improvements over the next four years. Previous Rate Studies An outside utility management/rate consultant has prepared the City's local sewer rate studies for many years. These local sewer rate analyses have generally been performed in conjunction and concurrently with the regional and local rate studies performed for DSRSD. The City's current Request for Proposals (RFP) to perform the local sewer rate analysis and model preparation will be the first such study conducted independently from those performed in the past as part of the combined regional/local sewer rate studies. Current Local Sewer Rate Structure The local sewer rate is structured to pay for the City's local sewer system, planning, engineering, operations, maintenance, and the renewal and replacement of the collection and pumping systems and related assets. The local sewer rate also pays for the Sewer Enterprise's portion of expenses on a pro rata basis for work by the City's Page 2 of 4
