7. Metropolitan Water Supply Allocation Plan
Allocation declared on April 14, 2009
Regional Shortage Level 2
Water Supplies will be reduced by no more than 20%
The impact to each water utilities varies depending on their water supply portfolio.
Implementation began July 1, 2009
Significant penalties will be assessed at end of the Allocation year – June 30, 2010

8. MWDOC Water Supply Allocation Plan
Plan takes into account the following:
Reward Agencies that Invested in Local Resources
Acknowledges Demand Hardening from Conservation and Recycling
Consider the Economic Impacts to Agencies heavily dependent on MWD water in the deeper stages of allocation
Allow for adjustments in gains or losses of local supplies
Provides for a regional approach with its Penalty Rate Structure

9. MWDOC Penalties Structure
MWDOC’s objectives in establishing a Penalty Rate Structure for Allocations should include the following:
A Financial Signal to reduce Water Use
Easy to Understand and Implement
Fair and Appropriate Penalty Rates
A “Melded” Impact Rate
Penalties apply to water retail agencies, not the end water users.

10. Melded Penalty Rate Structure
Client Agencies that go over their Allocation Limits pay their share of MWDOC’s Penalties
MWDOC Exceeds its Allocation with MWD
+ 700 AF
Pay 75% Share Total $554,400
Pay 25% Share Total $184,800
MWDOC will pay MET Penalties Totaling $739,200

11. Tracking and Reporting
MWDOC will track and monitor each client agency’s water usage monthly
To help them avoid over usage
Project total water usage locally and regionally
MWDOC will report local supply usage to MET
Change in local supply = Change in allocation amount.

12. Examples of Water Use Restrictions
No washing of hard or paved surfaces
Fix leaks within a reasonable time
No more than 7 days
Irrigation Restrictions
Time of day
Duration
No excessive water flow or runoff

13. Conservation Ordinances
Cities and Water Districts have been adopting mandatory conservation ordinances.
Ordinances supported by escalating enforcement measures.
