<br />7A - ATTACHMENT NO.3 <br />Saltworks Proposal- Water Group Summary Report (22 January 2010) Page 27 <br /> <br />of Redwood Shores. SBSA is a joint powers authority of which Redwood City is a part <br />owner. The recycled water project was developed as a partnership between Redwood <br />City and SBSA. The treatment plant currently has a permitted capacity of 29 mgd <br />(average dry weather flow). The recycled water facility at the plant treats wastewater to <br />California Title 22 criteria for "unrestricted use." The treatment facility and the City's <br />distribution system operate under permits issued by the Regional Water Quality Control <br />Board (RWQCB) and the California Department of Public Health (CDPH). Based on the <br />City's 2005 UWMP, the recycled water facility has the capability to produce up to 2,000 <br />AFY. It is expected to deliver approximately 290 AFY to customers in the Redwood <br />Shores area by the end of 2009. <br /> <br />Redwood City adopted a Recycled Water Use Ordinance in July 2008. The ordinance <br />established a Recycled Water Service Area (see Figure 4, this is the area to which the <br />ordinance provisions apply), and established requirements for use of recycled water for <br />various property types. The ordinance mandates that new apartment, condominium, <br />commercial, industrial, government, and institutional projects located within the Recycled <br />Water Service Area be dual plumbed for indoor use recycled water and provide for the <br />use of recycled water for landscape irrigation. <br /> <br />3.4.2 Availability of Recycled Water Supply for Saltworks Project <br />Based on discussions with City staff, Redwood City has the capability to supply the <br />recycled water demands of the Saltworks project, which is estimated using the <br />Attachment Q methodology to be approximately 1,825 AFY at buildout of the project. <br /> <br />A 24-inch recycled water main is located in Seaport Boulevard adjacent to the Saltworks <br />site. This main will serve primarily industrial customers along Seaport Boulevard and <br />east to the Port of Redwood City and the Pacific Shores development. City staff has <br />indicated that this main has adequate capacity to serve recycled water to the Saltworks <br />site. The Saltworks project would need to install a recycled water distribution system, <br />including pumping and operational storage (tank[s]). As shown in Figure 4, the majority <br />of the Saltworks site is currently not within the Recycled Water Service Area. The <br />Recycled Water Use Ordinance anticipates that the Service Area map will be amended <br />from time to time to accommodate new customers. Such an amendment (which is <br />accomplished by resolution of the City Council) would be required for the City to serve <br />recycled water to the Saltworks site. <br /> <br />The DMB Supply Report identifies the potential to develop an on-site recycled water <br />treatment and distribution system for the Saltworks project if City recycled water supplies <br />are not adequate. If such a system were developed, ownership and operation of the <br />system would need to be addressed. <br /> <br />3.4.3 Conclusions Regarding Recycled Water Supply <br />The anticipated uses of recycled water at the Saltworks project (e.g., toilet flushing, <br />cooling, and landscape irrigation) are all permitted uses under Title 22 and the City's <br />Recycled Water Use Ordinance. Administrative actions such as approval of an <br />Engineer's Report and amendment of the City's permits from the RWQCB and CDPH <br />would be necessary but are not considered impediments to serving recycled water to the <br />project. <br /> <br />20 <br />
