Ms. Ayala referred to page 6 of the staff report which indicated the Zone 7 Board <br />of Directors recommendation to the Regional Water Quality Control Board that injection <br />of recycled water would not be used until the community supports the use. <br /> <br /> Ms. Dennis asked what control Zone 7 had over the direct injection into the <br />groundwater basin? <br /> <br /> Mr. Lum said if injection was approved, DSRSD could proceed with the project <br />regardless of any Zone 7 position on the project. <br /> <br /> Mayor Tarver asked what it means to be manager of the groundwater basin. <br /> Mr. Lum believed that was open to interpretation among the agencies. <br /> <br /> Ms. Michelotti asked for clarification of the Livermore project. <br /> <br /> Mr. Lum said the Livermore project is different in scale and scope from the <br />DSRSD project in that it was to be a five year demonstration project on a smaller scale. <br />Since it is not relied upon for wet weather disposal it can be shut down or modified as <br />necessary. The DSRSD project is larger in scale and will be relied upon for year-round <br />wet weather disposal and once in operation will have to remain in continuous operation. <br />For those reasons there has been more public debate. <br /> <br /> Ms. Michelotti asked how this relates to the LAVWMA project. <br /> <br /> Mr. Lum said the Clean Water Revival Project is a near-term interim project to <br />provide wastewater capacity until the LAVWMA project is operational. The LAVWMA <br />project will provide longer-term disposal capacity. Perhaps in 20 to 25 years additional <br />wet weather capacity may be needed, and the Clean Water Revival Project could provide <br />disposal capacity at that time. It also provides additional water supply benefits. <br /> <br /> Ms. Ayala summarized that DSRSD needs the project to get rid of water more <br />than to get new supplies. <br /> <br /> Mr. Lum agreed there is a need for additional wastewater disposal capacity. The <br />water supply benefits are secondary. <br /> <br /> Ms. Ayala asked why the treated water could not be put into Alameda Creek. <br /> <br /> Mr. Lum said the Regional Water Quality Control Board has agreed to allow <br />reverse osmosis treated water in extreme wet weather events to be disposed of in the <br />Alamo Canal. The RO water is high quality water for disposal into the canal. However, <br />in the longer term basis, there are still environmental concerns to be resolved before a <br />blanket approval would be issued. <br /> <br />Pleasanton City Council 14 12/07/99 <br />Minutes <br /> <br /> <br />
