 BMP 2, 2010 Water Savings Based on BMP: 0 AFY

 BMP 2, 2040 Water Savings if Current Implementation Level is Maintained: 9.4 AFY

 BMP 2, 2040 Water Savings if Expanded (Double): 9.4 AFY

 BMP 2, 2040 Water Savings if Expanded (Quadruple): 9.4 AFY

3. System Water Audits, Leak Detection and Repair

AWA implements this BMP through ongoing repair and maintenance of its water distribution system. It has conducted system water audits since its founding. AWA plans to conduct an annual pre-screening audit of its entire system, then if indicated by the pre-screening audit, a system-wide detailed water audit will be completed. Water savings have not been quantified since detailed information on AWA leaks before and after BMP implementation is not available. New requirements in SB 1420, which mandates Urban Water Management Plans, will require agencies to determine unaccounted-for water (UAW).

4. Metering with Commodity Rates for All New Connections and Retrofit of Existing Connections

AWA has been converting services from flat rate to metered service upon transfer of ownership. As of 2011, there were 27 residential, commercial and raw water customers requiring metering, and 153 accounts yet to be converted from flat rate to volumetric billing. According to the 2010 UWMP, AWA should have fully metered its system as of 2013 and converted all accounts to volumetric billing. This BMP is fully implemented. Water savings have not been quantified since detailed information on customer water use patterns before and after BMP implementation is not available.

5. Large Landscape Conservation Programs and Incentives

There are approximately 30 accounts that are dedicated solely to large landscape irrigation in the AWA service area. AWA has offered surveys to these accounts, along with commercial, industrial, and institutional (CII) accounts since 1985 as an informal service. Current Program: The BMP was formalized in its 2010 UWMP. The BMP was not budgeted until FY12, so in 2010, there would be no water savings associated with BMP 5. Assuming that this level of 2010 implementation was maintained in 2040, there would be no conservation savings associated with this BMP in 2040.

Expanded (Double) Program: In FY12, AWA assumed it would complete 4 surveys and then increase that to 6 in each of the following years through FY16. In the UWMP, AWA assumed water budgets would be created for half of the surveys conducted. It was then assumed that creating a water budget would reduce landscape water use by 10 percent. AWA estimated average water use per landscape account in 2010 to be 19.5 AFY, so conducting a landscape survey and creating a water budget would save 1.95 AFY. According to the LAFCO, the project landscape water use in the AWA service area in 2010 is the same in 2025. It was assumed that no additional increase in landscape water use would occur between 2025 and

2040. If AWA expanded BMP 2 and conducted and prepared twice as many surveys and water budgets, it would save 11.7 AFY (6 landscape water budgets at 1.95 AFY savings each).

Expanded (Quadruple) Program: If AWA doubled its expanded program in 2040, it would perform 12 water budgets (24 landscape surveys), resulting in a savings of 23.4 AFY.

In summary, the following water savings could be achieved:

 BMP 5, 2010 Water Savings Based on UWMP: 0 AFY

 BMP 5, 2040 Water Savings if Current Implementation Level is Maintained: 0 AFY

 BMP 5, 2040 Savings if Expanded (Double): 11.7 AFY

 BMP 5, 2040 Savings if Expanded (Quadruple): 23.4 AFY

6. High-Efficiency Clothes Washing Machine Financial Incentive Programs

Current Program: AWA had not yet implemented this BMP at the time of its 2010 UWMP and did not budget for BMP 6 until FY12. Assuming that this level of 2010 implementation was maintained in 2040, there would be no conservation savings associated with this BMP in 2040. AWA intended to begin a rebate program in the Lake Camanche Village area initially, providing $75 rebates for high-efficiency washing machines.

Expanded (Double) Program: In FY12, AWA planned to give 35 rebates, increasing the number of rebates to 70 rebates per year through FY16. Each rebate results in a savings of 0.025 AFY. As described in BMP 1, in 2040, it is estimated there will be 10,941 single family accounts and 52 multi-family accounts. If AWA provided rebates to 5 percent of these customers, it would provide 550 rebates, resulting in a water savings of 13.8 AFY.

Expanded (Quadruple) Program: If AWA doubled its expanded program in 2040, it would provide rebates to 10 percent of its single family and multi-family customers. This would result in 1,099 rebates and a savings of 27.5 AFY.

In summary, the following savings could be achieved:

 BMP 6, 2010 Water Savings Based on UWMP: 0 AFY

 BMP 6, 2040 Water Savings if Current Implementation Level is Maintained: 0 AFY

 BMP 6, 2040 Savings if Expanded (Double): 13.8 AFY

 BMP 6, 2040 Savings if Expanded (Quadruple): 27.5 AFY

7. Public Information Programs

AWA promotes public awareness of water conservation through bill inserts, brochures, a demonstration garden, and special events throughout the year. It has and will continue to implement this BMP. CUWCC does not provide a methodology for quantifying water savings from this BMP.

8. School Education Programs

Historically, AWA provided presentation and demonstrations to schools and classes upon request. Per the 2010 UWMP, it plans to formalize its school education program, focusing on outreach to fifth graders (believed to be the age to best reach children and instill the importance of water conservation). AWA gives presentations to all fifth grade classes in its service area and provides students with low-flow showerheads and conservation tips. Water savings associated with the distribution of low-flow showerheads are captured in BMP 2. There is no method available from the CUWCC to quantify water savings from the other measures included in this BMP.

9. Conservation Programs for Commercial, Industrial, and Institutional Accounts

Current Program: According to the 2010 AWA UWMP, in 2010, AWA had about 389 CII accounts. It formalized this BMP in its UWMP and did not budget for it until FY12. Assuming that this level of 2010 implementation was maintained in 2040, there would be no conservation savings associated with this BMP in 2040.

Expanded (Double) Program: AWA estimated average water use of 4 AFY per CII account and a 5 percent water savings per survey conducted (0.20 AFY savings per survey). In FY12, it assumed it would conduct 10 CII surveys, increasing to a total of 30 surveys per year. Based on population increases and the percent of CII accounts in 2010, in 2040, AWA will have a service area population of 44,395 and 616 CII accounts. If AWA could conduct surveys for 8.4 percent of CII accounts (equivalent to 52 in 2040), it would achieve a water savings of 10.4 AFY.

Expanded (Quadruple) Program: If AWA doubled its expanded program in 2040, it would conduct surveys for 16.9 percent of CII accounts. This would result in 104 surveys and a savings of 20.8 AFY.

In summary, implementation of BMP 9 results in the following:

 BMP 9, 2010 Water Savings Based on UWMP: 0 AFY

 BMP 9, 2040 Water Savings if Current Implementation Level is Maintained: 0 AFY

 BMP 9, 2040 Savings if Expanded (Double): 10.4 AFY

 BMP 9, 2040 Savings if Expanded (Quadruple): 20.8 AFY

10. Wholesale Agency Assistance Programs

AWA offers the same conservation measures to all customers, including wholesale customers – Jackson, Plymouth, Drytown Community Services District (CSD), Pine Grove CSD, Rabb Park CSD, and Mace Meadows. AWA provides surveys, prepares water budgets, and provides residential and industrial rebates to its wholesale customers. Water savings have not been quantified since detailed information on customer water use patterns before and after BMP implementation is not available.

11. Retail Conservation Pricing

AWA uses a tiered water rate structure for water service rates in a portion of its service area. It will continue to charge volumetric pricing and expand this practice to the rest of its service area.

12. Conservation Coordinator

The Agency’s Conservation Coordinator retired and the position has not yet been filled due to budget constraints. AWA plans to appoint a replacement Conservation Coordinator staffed at half-time. It is anticipated that when this position is filled, additional water savings will be achieved, however, CUWCC has not identified a method to quantify savings from this BMP.

13. Water Waste Prohibition

AWA adopted a water conservation policy that supports local ordinance that prohibits water waste. In addition, it will consider the development and adoption of a water waste ordinance, a year-round policy that prohibits overwatering landscape, system leaks, and open hoses for example. Potential water savings from this BMP have not been quantified since detailed information on customer water use patterns before and after BMP implementation is not available.

14. Residential Ultra-Low-Flow Toilet Replacement Programs

Current Program: AWA began offering rebates for ULFT to customers in the Lake Camanche Village area as a pilot program. Assuming 30 rebates are offered each year in Lake Camanche Village, a savings of 0.9 AFY could be achieved (equivalent to 0.029 AFY per toilet replaced, reaching 0.5 percent of the population). If AWA maintains these current levels of implementation and offers 30 rebates in 2040, AWA can expect to see the same 0.9 AFY in savings in 2040.

Expanded (Double) Program: As described in BMP 1, population is expected to increase to 44,395 in 2040, resulting in estimated single family accounts totaling 10,941 and multi-family accounts total 52. If AWA provided rebates to 1 percent of these customers in 2040, it would provide a total of 110 rebates, resulting in a water savings of 3.2 AFY.

Expanded (Quadruple) Program: If AWA doubled its expanded program in 2040, it would provide rebates for 2 percent of its customers in 2040. This would result in 104 surveys and a savings of 20.8 AFY.

In summary, implementation of BMP 14 results in the following:

 BMP 14, 2010 Water Savings Based on UWMP: 0.9 AFY

 BMP 14, 2040 Water Savings if Current Implementation Level is Maintained: 0.9 AFY

 BMP 14, 2040 Savings if Expanded (Double): 3.2 AFY

Maximum Theoretical Expanded Program (85 gpcd)

In 2020, AWA anticipates reaching a gpcd of 166. Assuming this gpcd in 2040, AWA would use 8,260.5 AFY in 2040, with an estimated 2040 population of 44,395. If AWA were to achieve 85 gpcd in 2040, it would use 4,229.8 AFY in 2040. This results in a maximum theoretical savings of 4,030.7 AFY.
