7 have been working together to provide the best possible project/solution. There have been numerous workshops, public meetings, media coverage, etc. This project provides the key to meet the needs of the City of Dublin in the short term; provides a salt management tool in the longer term; and provides a part of managing the water resources as set forth in the LAVWMA Principles of Agreement. Steve Gittings, Water Resources Manager, City of Livermore, gave a brief overview of the RO system in the City of Livermore. The project' was initially evaluated and it was determined that the RO microfiltration unit would be less expensive than additional pipelines. The City wanted to see if a microfiltration system could be beneficial during the drought. He felt the technology has proven itself. The public relations used by the City was similar to that of San Ramon and Dublin. In 1989 the first citizens advisory committee was formed and more recently Zone 7 formed a citizens groundwater advisory committee. He also mentioned the City gives tours and public meetings to explain how the system works. In 1991 an additional export pipeline analysis was done which continued to support the position that micro filtration was less expensive than constructing additional pipelines. In 1991/1992, the City did a preliminary design of an advanced reclamation plant and prepared a negative declaration. In 1992, the recycling report supported the use of RO effluent for irrigation and groundwater injection. In 1994 the City started-micro~ltration and reverse osmosis testing and in 1994/1995 the advance water reclamation facility design was done. In 1996/1997 the contract was awarded and the project started. The City of Livermore to date has expended $7.682 million with an expected additional $1.062 million in costs. These figures do not include the operations and maintenance costs. The system has performed as predicted and the organics, metals and inorganics are far below the drinking water minimum standards. He mentioned the equipment safeguards. The system is run by a computer that has set points that will shut the system down automatically if parameters that have been predetermined are exceeded. Example: if the PH changes in the water, the units automatically shut down.. He said the water will travel approximately ten miles from the injection point and will be in the ground approximately thirty to forty years before it is extracted into the potable water source; therefore the water quality is excellent. John Stein, Livermore City Councilmember, said the City of Livermore has been reusing water on its golf course since 1966. The project that the City started for RO was a demonstration project for three reasons: 1) improving the salt balance; 2) increasing the sewer capacity of the system; and 3) providing water during periods of drought. The system has the support of DSRSD and Zone 7. He listed the criteria that were set before the injection could occur. The first requirement is that the RO plant operate successfully for six months without problems in the effluent; 2) a redundant examination of the plans for the plant be done by an outside consultant and 3) the City has the option, in the event of a failure, to turn off the plant. The City of Livermore has spent $7 million in the construction, design and operation of the RO facility. It appears to provide reusable water that meets or succeeds all the regulatory standards. It is currently being used to water the golf courses. The project is necessary to demonstrate to the public that water reuse is an important component for the State of California to meet its projected water needs. Even without future growth there is no guarantee that the State water Pleasanton City Council 3 09/08/98 Minutes
