THE CITY OF <br />Chapter 3 — <br />System Description PL£ASANTON <br />3.3.4 Emergency Interties <br />The City currently has two existing pipeline interties with DSRSD and one pipeline intertie with the City of <br />Livermore for rapid emergency response. These interties are strictly for emergency conditions, such as a <br />major pipeline break, supply contamination, or interruption of deliveries due to earthquake, flood, or <br />other disaster. <br />3.3.5 Recycled Water Facilities <br />In June 2015, construction began on the City's Recycled Water Project (RW Project), which included the <br />construction of approximately 51,500 lineal feet (LF) of new recycled water pipeline, ranging in diameter <br />from 6 inches to 20 inches, and repurposing approximately 22,400 LF of existing potable pipeline into the <br />recycled water system. The RW Project was funded through a Clean Water State Revolving Fund Program <br />loan and Proposition 1 Program Grant Agreement with the SWRCB, with the goal of largely replacing <br />existing potable irrigation demands along the distribution system with recycled water; thereby reducing <br />potable water demands. <br />Construction of the RW Project was substantially completed by September 2016. Currently, the City has <br />connected 92 out of 98 projected sites (144 out of 161 metered connections). <br />3.4 SERVICE AREA CLIMATE <br />The City's climate is characteristically Mediterranean, with hot, dry summers and cool, moist winters. This <br />section discusses historical climate in City's water service area and potential effects of climate change. <br />3.4.1 Historical Climate <br />The historical climate characteristics affecting water management in the City's water service area, <br />including average evapotranspiration (ET.), rainfall, and temperature, are shown in Table 3-1.
