Advanced Water Technologies (AWT)
<br />AWT is calculated by multiplying the estimated GW production for that year (Section 6.1 of the City’s UWMP) with the
<br />percentage of Total Basin Production for that year.
<br />C.5 Reliance on Water Supplies from the Delta Watershed
<br />Metropolitan’s service area as a whole, reduces reliance on the Delta through investments in non-Delta water supplies,
<br />local water supplies and demand management measures. Quantifying the City’s investments in self-reliance, locally,
<br />regionally, and throughout Southern California is infeasible for the reasons as noted in Section C.6. Due to the regional
<br />nature of these investments, the City is relying on Metropolitan’s regional accounting of measurable reductions in supplies
<br />from the Delta Watershed.
<br />The results shown in Table A.11-3 demonstrate that Metropolitan’s service area, including the City, is measurably reducing
<br />its Delta reliance. In the near-term (2025), the expected outcome for normal water year reliance on supplies from the
<br />Delta watershed decreased by 301 TAF from the 2010 baseline; this represents a decrease of 3 percent of 2025 normal
<br />water year retail demands. In the long- term (2045), normal water year reliance on supplies from the Delta watershed
<br />decreased by 314 TAF from the 2010 baseline; this represents a decrease of just over 5 percent of 2045 normal water year
<br />retail demands.

<br />C.6 Infeasibility of Accounting Supplies from the Delta Watershed for Metropolitan’s
<br />Member Agencies and their Customers
<br />Metropolitan’s service area, as a whole, reduces reliance on the Delta through investments in non-Delta water
<br />supplies, local water supplies, and regional and local demand management measures. Metropolitan’s member
<br />agencies coordinate reliance on the Delta through their membership in Metropolitan, a regional cooperative
<br />providing wholesale water service to its 26 member agencies. Accordingly, regional reliance on the Delta can only be
<br />measured regionally—not by individual Metropolitan member agencies and not by the customers of those member
<br />agencies.
<br />Metropolitan’s member agencies, and those agencies’ customers, indirectly reduce reliance on the Delta through
<br />their collective efforts as a cooperative. Metropolitan’s member agencies do not control the amount of Delta water
