Rain to the rescue: New Report on Stormwater Capture as Drought Buster

NRDC and TreePeople Highlight Stormwater’s Power to Combat Drought and Build Long-Term Local Resilience

From the Natural Resources Defense Council and TreePeople:

NRDC Logo Newtree-people-logoCalifornia could utilize up to 630,000 acre-feet of new, untapped water supply if urbanized areas in Southern California and the San Francisco Bay captured stormwater, an issue brief released today by the Natural Resources Defense Council (NRDC) and TreePeople shows. The City of Los Angeles could replace almost half (258,000 acre-feet per year) of its 575,000 acre-feet annual water supply – which is mostly imported – if the required infrastructure, programs and policies were implemented.

“There’s no silver bullet to solving California’s water crisis, but there are 21st century solutions to build more water supply and replenish the groundwater safety net that’s quickly running out,” said Becky Hayat, an attorney with NRDC’s water program. “Stormwater capture is a big piece of that puzzle. As this historic drought drags on, it’s critical that we take collaborative action – backed by government and community leadership – to invest in cost-effective, environmentally sound options that really work and
that will help us to weather future droughts.”

Rain to the Rescue: Stormwater’s Power to Increase California’s Local Water Supplies highlights how stormwater is an obvious source, but often overlooked. As California enters a historic sixth year of drought and the state grapples with the realities of a hotter, drier future due to climate change, communities must consider “new” sources of local water supply.

For example, for each inch of rain that falls onto the City of Los Angeles, 3.8 billion gallons of runoff is flushed out to the Pacific Ocean, dragging animal waste, trash, metals, chemicals and other harmful contaminants with it. This not only puts marine life at risk, but people too, for days after it rains. But if the City locally captured rainfall instead, it could satisfy between 30 percent and 45 percent of its current water demand if the required infrastructure, programs and policies were implemented. And if the required
infrastructure, programs, and policies were funded and implemented, these investments could provide billions of gallons of water for public use and decrease the City’s reliance on imported water.

Eighty-nine percent of LA’s water has historically come from imported water supplies (from the eastern Sierra Nevada Mountains via the Los Angeles Aqueduct, the San Joaquin-Sacramento Rivers via the California Aqueduct, and the Colorado River Basin via the Colorado River Aqueduct). Currently, the City actively captures approximately 29,000 acre-feet of stormwater annually, and another 35,000 acre-feet passively (in open spaces and other unpaved areas). Modeling analysis in the City’s first-ever Stormwater Capture Master Plan – created by the Los Angeles Department of Water and Power (LADWP) and
engineering firm Geosyntec, with facilitation by TreePeople – estimated long-term potential capture between 169,000 and 258,000 acre-feet per year, in the conservative and aggressive scenarios, respectively.

“Los Angeles can build a water-resilient future. Instead of importing water from Northern California and the Colorado River Basin, the City can capture it locally, where it falls,” said Deborah Bloome, senior director of policy with TreePeople. “If the City of Los Angeles aggressively invested in capturing rainwater, it would not only drastically reduce the pollution running into our oceans and waterways, but the City could truly become more water-resilient.”

Key takeaways

• Stormwater capture in urbanized Southern California and San Francisco Bay region could potentially increase water supplies by 420,000 to 630,000 acre-feet per year – the equivalent of filling the Rose Bowl with water 1,622 to 2,432 times!

• Groundwater infiltration offers the greatest stormwater-based opportunity to increase urban water supplies. In areas in Southern California and the Bay area overlying groundwater basins used for municipal water supply, 365,000 to 440,000 acre-feet of runoff could be captured and stored each year through projects such as green streets, park retrofits, building and parking lot retrofits, and infrastructure changes to divert runoff to large-scale spreading grounds.

• Smaller scale rainwater capture could increase water supplies by up to 190,000 acre-feet per year in Southern California and the Bay area, of which nearly 145,000 acre-feet could be gained via residential rainwater capture systems, such as rain barrels and cisterns. Yields could be even higher if rooftop rainwater capture were installed in areas where infiltration and groundwater recharge are feasible.

U.S. EPA Announces $28 Million for Environmental Improvements on Tribal Lands in California

From the US EPA:

epa-logoToday, the U.S. Environmental Protection Agency announced almost $28 million in funding for California tribes to support environmental programs, drinking water and wastewater infrastructure and community education. The announcement was made at the 24th Annual Regional Tribal Conference in San Francisco.

“Tribes continue to make great strides in environmental protection and improving public health,” said Alexis Strauss, EPA’s Acting Regional Administrator for the Pacific Southwest. “This year, EPA is supporting water quality projects and water infrastructure for California tribes with over $14 million in funding.”

Approximately $9 million was awarded directly to California tribes to support a wide variety of projects including monitoring, watershed protection and restoration, water and energy efficiency, wastewater reclamation, and treatment systems. Another $5.1 million will go to the Indian Health Service to support tribal drinking water and wastewater infrastructure, plant operator training and technical assistance.

California tribes will use an additional $13.8 million to continue tribal environmental programs, clean up open dumps and contaminated lands, develop programs to monitor, protect, and improve air quality, and conduct targeted community outreach and community education.

Among the results of EPA funding:

  • This year the Quechan Tribe cleaned up two open dumps and collected more than 1,000 tires from its Reservation.
  • Dry Creek Rancheria used EPA funds to leverage a $3.5 million grant to restore the creek running through the Rancheria to the Russian River. The project will fund the entire creek restoration, restoring riparian habitat, replacing invasive species with native plants, restocking the creek with salmon, and setting up a system to use purified wastewater to keep the creek flowing during dry periods.
  • The Yurok Tribe treated a surface drinking water source that was the cause of an E. coli outbreak in 2014. The tribe’s Kenek Water Treatment Plant was at a high risk for running dry due to the drought.

These funds are critical in building the capacity of tribes to carry out environmental work. As most tribes in the Pacific Southwest have small governments, one goal of the funding is to assist tribes in developing the ability to establish and sustain environmental protection programs and make informed decisions to protect public health and environmental quality. The funds are also used to develop environmental and public health ordinances.

The EPA’s Pacific Southwest Region is home to 148 tribal nations.

Weekly Water and Climate Report:  Southeast drought fueling wildfires

From the USDA:

weekly-water-reportThe Natural Resources Conservation Service produces this weekly report using data and products from the National Water and Climate Center and other agencies. The report focuses on seasonal snowpack, precipitation, temperature, and drought conditions in the U.S.

This Southern Area Resource Map from the Federal Interagency Geographic Area Coordination Center shows many active fires in the Southeast. Drought conditions in a large area of the southeastern U.S. are creating situations for increased wildfire potential across the area. Most of this same area has state-declared burn bans in effect.
