CITY OF COLTON INTEROFFICE MEMORANDUM TO: COUNCIL MEMBER SENNETT APPROVAL: THOMAS K. CLARKS, T RIM WATER & WASTEWATER DIRECTOR FROM: MIKE MEDINA, WATER UTILITIES COORDINATOR SUBJECT: REPORT ON WATER PRESSURE PROBLEM IN RECHE CANYON DATE: FEBRUARY 3, 1997 BACKGROUND: _ Per the 1985 Water Master Plan, the Wild Canyon Reservoir was constructed in 1987 to accommodate the various elevations throughout Reche Canyon Zone 11 with fire Protection and Water storage. Due to the elevation of the Wild Canyon Reservoir (1509'), the, pressureincreased in the Reche Canyon Zone 11 water system. At that time, the then Water Utilities Manager decided that the City would provide the existing, effected residents with pressure regulators. All residences constructed after 1987 were thereby required, by the City, to have pressure regulators installed by the developer, after the water meter on private property. This requirement was made per the Uniform Plumbing Code (Attachment "A") and Resolution #3805 Customer Service Policy (Attachment "B"). DISCUSSION/ANALYSIS: Several of the Reche Canyon Zone 11 residents felt that the water pressure was still too high. Therefore, Council Member Bennett requested the Water Division to investigate the problem. At the request of the Water Utilities Manager, the City Engineer conducted a water pressure study of the Reche Canyon Water Zone 11 in early 1994. On April 4, 1994, they provided an analysis to the Director of Public Works and the Water Utilities Manager, which was reviewed and then forwarded to Council Member Bennett (attachment "C") The analysis provided two alternatives. At the time the report was submitted, staff initiated Alternative No. 1. The alternatives were as follows: Alternative No 1: City will provide residents having high water pressure problems with a list of vendors that provide a more superior type of pressure regulator for a fee. Alternative No. 2: The City would install pressure regulators on water mains. This alter- native is expensive and would require a modification of the Water Master Plan to reflect new pressure zones. The 1991 Water Master Pian is currently being updated.-,
