18. Orange County Regional Alliance Under SBx 7-7 18

19. Regional Alliance Under SBx7-7
•
Under SBx7-7 (20% by 2020) retail water suppliers are able to join one or more Regional Alliances
•
Benefits of a Regional Alliance

It serves as an insurance policy for local compliance

No added risk to retail agencies

The entire Alliance benefits from regional investments such as conservation & recycled water



MWDOC provides annual monitoring for Regional Alliance and individual retail agency compliance 19

20. Calculating a Regional Alliance
•
Two step process to calculate a regional compliance target
1.
Each retail water agency must first calculate their individual target
2.
Individual targets are then weighted by population and averaged over the Regional Alliance 20

21. Determining Compliance
•
Provides multiple ways to win
•
If the Regional Alliance successfully meets its compliance target

All agencies in the alliance are deemed compliant regardless of individual performance
•
If the Regional Alliance fails to meet its compliance target

Each individual supplier will have an opportunity to meet their targets individually 21

22. Data Reporting for a Regional Alliance
•
The OC Regional Alliance is included in MWDOC’s regional UWMP

MWDOC provides all the required reporting, and retail agencies simply cite that they are part of the Regional Alliance in their individual UWMPs
