P BY DATE: July 5, 1990 (City Council Meeting 7-25-90) SUBJECT: Consideration of a Requirement to Install LOW — Water Consumption Fixtures and Devices in all New Construction (Public Hearing) At the May 2, 1990 City Council Meeting, staff was directed to prepare a modification to the Building Code that would require low -flow fixtures in new construction. summary Ventura County has problems with groundwater overdraft, seawater intrusion, drought, and increasing demands on limited water supplies. Efficient use of limited water supplies is needed. One type of water waste that can be eliminated with minimal cost and impact on life-styles is the water consumed by inefficient plumbing fixtures and devices. To eliminate this waste, it is proposed that the Plumbing Code be amended to require water -efficient plumbing fixtures in new construction. Since the provisions of the proposed ordinance will constitute a change or modification of the requirements of the Municipal Code, the City Council will have to adopt the necessary findings that this action is reasonable in light of local conditions. Background Since 1983, the California Uniform Plumbing Code has required 3.5 gallon per flush (gpf) water closets in new construction. Even more efficient water closets, designed to use only 1.6 gpf, have been successfully marketed. Their use has already been mandated in many jurisdictions, both within California and throughout the nation, due to their effectiveness in 799 Moorpark Avenue Moorpark, California 93021 (805) 529-6864 The Honorable City Council June 6, 1990 Page 2 reducing water usage. Governor Deukmejian recently signed Assembly Bill 2355 (co- sponsored by Assembly Member Jack O'Connell), requiring all buildings constructed after January 1, 1992, to install water closets and associated flushometer valves, if any, which use no more than 1.6 gpf, and urinals and associated flushometer valves, if any, which use no more than 1.0 gpf. Massachusetts, New York, Washington, Rhode Island, and Connecticut have implemented similar requirements. Federal legislation has been introduced to set national standards and require labels on water -using products, in much the same manner as the National Appliance Energy Conservation Act of 1987 regulates energy -using appliances. The Federal water -use standards would be the same as California's. Even before AB 2355 was passed, the County Water Conservation Management Program, Supervisor Lacey, representing the Board, and the Association of Water Agencies invited interested parties to meet to discuss the feasibility and desirability of mandatory ultra -low consumption plumbing fixtures in the County. This voluntary group, which came to be called the Plumbing Efficiency Research Group (PERG), investigated the performance of water -efficient plumbing devices (referred to herein as ultra -low consumption [ULC] plumbing devices) and the potential measures to mandate them in new construction. Building officials, plumbing contractors, water districts, sanitation districts, and others, were represented on this committee. The committee's findings supported the use of such devices. Representatives from Goleta Water District, Monterey Peninsula Water Management District, Las Virgenes Water District, and the City of Santa Monica related their successful experiences with ULC water closets at the PERG meetings. Monterey has at least 4,000 homes using ULC water closets. Goleta has at least 10,000 water closets in place and more than six years of experience with ULC water closets. The performance of these ULC fixtures - in the home, in transporting waste from the house to the main sewer line, and impacts on wastewater treatment - has been positive. The PERG committee found ULC plumbing fixtures are as reliable as conventional water closets. Because of the significant amount of water which can be saved, several cities in Ventura County are adopting requirements for ULC plumbing fixtures before the 1992 effective date of the new law. The City of Ventura was the first to do so, with an amendment to the plumbing code The Honorable City Council June 6, 1990 Page 3 effective January 1, 1990. The cities of Camarillo and Simi Valley followed with effective dates of April 25, 1990 and July 5, 1990, respectively. Ventura County's was effective July 1, 1990. These amendments set water -use standards for water closets, showerheads, and sink faucets. Similarly, Calleguas Municipal Water District passed a resolution on December 20, 1989, encouraging local governments to require the installation of ULC water closets, urinals, and showerheads in new construction within their service area. Calleguas MWD's service area covers a large area in the southeastern portion of the County, including the cities of Simi Valley, Moorpark, Thousand Oaks, Camarillo, Oxnard and surrounding unincorporated areas. The Association of Water Agencies (AWA) has taken a position supporting requirements for ULC plumbing fixtures. This recommended plumbing code amendment would apply to the installation of plumbing fixtures in all new residential, commercial, and industrial construction within the City of Moorpark. Effective August 30, 1990, all new construction would be required to be equipped with 1.6 gpf water closets and 2.5 gallon per minute (gpm) showerheads. Availability of these fixtures does not appear to be a problem. At least three wholesale and six retail plumbing stores in Ventura County stock ULC water closets, with many more stores indicating the fixtures could easily be obtained once a demand exists. Based on a 1980 study by the County Department of Water Resources, water closet flushing comprises 42% of interior water use, the largest use of water inside the home. The Department assumed that if there were 20 flushes per household per day (EPA estimate) the potential water savings for households in the unincorporated area of the County would be: 46% savings in water and wastewater 38 gal/day saved per household 13,870 gal/year saved per household If similar amendments were approved countywide, approximately 132, 444, 630 gallons, or 406 acre feet of water could be saved in the County before the State law becomes effective in 1992. This amount of water would support about 1,765 people a year in Ventura County. The second largest use of water inside the home is for bathing and showering. Ultra -low consumption showerheads use 2.5 gpm, compared to the State standard of 2.75 gpm. Many The Honorable City Council June 6, 1990 Page 4 showerheads certified at 2.5 gpm are available. The potential water savings from the use of ULC showerheads can vary considerably depending upon showering time and water pressure. Staff Recommendation It is recommended that the City Council introduce the Ordinance.
