However, the WTF is expected to be constructed in two 150 mgd <br />phases, for a capacity of 300 mgd, to meet the projected 2025 water demand requirements. <br />The booster pumping station structures would be designed to deliver approximately 300 mgd. <br />For the 2025 phase of the Proposed Project, the power substations would be designed to <br />accommodate power requirements of delivering approximately 300 mgd, <br /> <br />Overall construction of the 2025 phase of the <br />Proposed Project, for both Out-Valley and In- <br />Valley, is expected to last approximately 17 <br />years. Construction of the Out-Valley project <br />components would commence in 1997. <br />Construction of the 2025 phase Out-Valley <br />components should be complete around 2008, <br />Construction of the In-Valley project <br />components would commence in late 1996, <br />with the 2025 phase expected to be complete <br />around 2013. Additional equipment, such as pumping equipment, would be subsequently <br />installed in phases to match water demands, but these installations would not require <br />additional construction. <br /> <br />Overall construction of the 2025 <br />phase of the SNWA-TTF project is <br />expected to last approximately 17 <br />years. <br /> <br />SUMMARY <br /> <br />S-ll <br />
