8 Affordable Water Solutions
Transcript of 8 Affordable Water Solutions
2002 Lawrence Livermore study estimated 10% California's public drinking water wells exceed reg. limits for nitrates.
Tulare – 40% of wells exceed reg. limits
Prioritize clean drinking water projects in remaining 84, 50, 1E funds. Existing California law (SB 610/221) requires residential developments > 500 units to have written verification of 20-year water supply.
Department of Finance estimates CA population will increase by 23 million in 40 years.
Developers can achieve water-neutrality with: on-site conservation and recycling and off-site demand mitigation fund.
Camino Tassajara development: 626,00 g.p.d. spent to 452,000 g.p.d. saved.
Can be applied at the local level, without state legislation. 5. Water-Neutral Development Context: 3 Challenges 1. Financial Crisis
3. Changing Hydrology By 2050 the annual volume of water naturally stored as snow will decrease by 3.8 to 6 million acre-feet 2. Fisheries Collapse 8 Affordable Solutions July 2009: Fitch Investors lowers California's general obligation bond rating from A- to BBB – two grades above "junk" bond.
2010: $20 Billion Budget Deficit $ + + = Water solutions in California must be financially sound, environmentally sustainable, and robust in the face of hydrologic uncertainty. Source: Salmon Water Now California discharges 4 million acre-feet of used water to the ocean every year.
SWRCB unanimously adopted goal of 1 million recycled AF by 2020, 2 million recycled AF by 2030.
Orange County Groundwater Replenishment System creates 70 m.g.d. – enough for 500,000 people.
Need for broad standards to guarantee public health and reduce planning uncertainty – SB 918. 2. Increase Water Recycling 3. Science-Based Flow Standards Complete ban on commercial salmon fishing in 2008 & 2009.
Lower American River flow standards were adopted in 1958.
Flow standards should be continuously updated in response to climate change and ecosystem monitoring – prevent, rather than respond to crisis.
Fund via SWRCB's existing fee authority on diverters. BDCP is focused on five 3,000 c.f.s. water intakes with the capacity to divert 15,000 c.f.s. from the Sacramento River.
Costs have jumped from $4 billion to over $10 billion.
Success of such a large project is uncertain – faces significant local opposition, and maybe not be permitted.
BDCP should fully analyze 3,000 c.f.s. tunnel (potentially fewer impacts, more affordable, emergency water) 4. Analyze Smaller Delta Tunnel Courtesy Community Water Center Courtesy Orange County Sanitation District Sierra headwaters annually produce: $2.2 billion worth of natural goods like water and timber, $3 billion in tourism, and 74% of California's hydroelectric.
Bond freeze stopped critical projects for restoration, land acquisition, water quality, and fire defense.
Reliable Electrical Services Investment Act added a rate component on PG&E, So. Cal Edison, etc. to fund energy research in public interest.
Similar model could be applied to hydroelectricity to fund California Department of Conservation's Statewide Watershed Program.
Demonstrated nexus between watersheds & hydroelectricity: riverbank erosion, sedimentation, and runoff patterns.
In 3 years, LAO estimates that California's debt service will reach 10% of the state budget.
An affordable bond of $3 billion could address critical projects, and might look like:
A 75% local cost share would help ensure cost-effective projects are selected.
6. San Joaquin Valley Solar San Luis Drainage Unit includes 730,000 acres in Westlands, Panoche, and Pacheco Water Districts – 379,000 acres are "drainaged impaired."
Willing-seller program – more than 44,000 acres have been retired, and an additional 150,000 are possible.
Existing Central Valley PV Solar: Robert O. Schulz in Oakdale, 5 MW Calrenew-1 in Mendota. "This is huge for this small, dusty farm town."
Benefits: energy independence, regional economy, water quality, environment. 8. Smaller Water Bond 7. Protect Primary Water Source Questions? Comments? Vince King Feather River CRM SunPower Dan Bacher All Access Image 2009: Only 39,500 salmon return in the Fall 2001: 804,000 spawning salmon return to the Delta $1,500 million for innovative regional water supply projects
$300 million for the Clean Water State Revolving Fund
$300 million for Drinking Water State Revolving Fund
$250 million for Delta Habitat Restoration
