February 8, 2013
2009 Water Legislation
Feb. 28, 2008 Governor Schwarzenegger’s letter to Legislature identifies conservation as part of comprehensive Delta package
On November 4, 2009, the Legislature passes a conservation bill – SB 7 – as part of package of water bills that include Delta reforms and water bond
Option 1(Water Code 10608.20(b)(1))
• Flat 20% reduction in per capita water use from baseline
20% reduction from base gpcd
Option 2(Water Code 10608.20(b)(2))
55 gpcd indoor
Model ordinance outdoor
10% CII reduction
+
+
Total of specific efficiency measures:
(a) 55 gpcd indoor use
(b) Implementation of model landscape ordinance
(c) 10% reduction in CII water use
Option 3(Water Code 10608.20(b)
(3))
• Option 3 agencies must achieve 5% reduction except
• No reduction if use below 100 gpcd

Option 4• Developed by Dept.
of Water Resources (DWR)
• Targeted for 20% statewide if everyone used
• Outdoor used as gap-filling factor

Base gross water use Recycled water
Long-term
storage
Delivery to other
suppliers
Ag use
Water in distribution system
Can exclude process water from gross water use if a “substantial percentage of industrial water use” to avoid “disproportionate burden on another customer sector” (Water Code 10608.24(e))
Baseline – Time Periods(Water Code 10608.12(b))

Target vs. ComplianceSBX7 7 contains detailed rules only for setting conservation targets
SBX 7 says that a supplier can meet its conservation target through combination of measures, but no “disproportionate burden” on any sector (Water Code 10608.26(b))

Results – 2010 Plan Targets
• April 2012 report by DWR identifies how many agencies chose various options and how much conservation urban water suppliers have targeted for 2020

Future – DWR 2016 20x2020 Report(Water Code 10608.42)
• By Dec. 31, 2016, DWR report on overall state progress toward 20% gpcd reduction and recommend next steps
