And updates to the Tujunga Spreading Grounds facility in the San Fernando Valley doubled its ability to capture stormwater from 8,000 acre-feet per year to 16,000, which can potentially provide enough water for 64,000 households each year. Shaw Wetlands Park Project to convert a 46-acre landfill into a wetlands park that can collect stormwater runoff. Since its approval, the Los Angeles County Department of Public Works has awarded $400 million to over 100 regional infrastructure projects, such as the Rory M. has more resources than almost any other place in the country to harness rainfall to recharge groundwater basins for future use. California Natural Resources Secretary Wade Crowfoot called Measure W a “ world-leading policy,” that can also help reduce pollution flowing into oceans and bays. The program allocates $280 million annually for multi-benefit stormwater projects throughout the county. In 2018, Los Angeles County voters approved Measure W, a special parcel tax funding the Safe Clean Water Program. Stormwater capture plays an important role in the city and county of Los Angeles’ overall plan to conserve and source water locally. Rainwater has many benefits and potential uses, such as washing clothes, watering gardens, flushing toilets, and washing cars. Rainwater quality is much higher, given that groundwater generally contains more contaminants, including soil, organic matter, fertilizers from gardens, and oil residue from driveways. Rainwater refers only to the rain that can be captured in a storage tank prior to any contact with the ground. Stormwater after being treated is safer, and as such becomes a “recycled water” supply. Collecting and reusing stormwater can conserve potable water, diminish downstream environmental impacts, and help prevent overflooding of the stormwater system. It includes rain that falls on rooftops, directed through gutters and downpipes onto land or into drains, and rain falling on ground surface areas, such as roads, driveways, gardens, footpaths, and lawns. It occurs when the rate of precipitation is greater than the rate at which it can infiltrate or soak into the soil (in other words, when the soil is saturated). Stormwater is the water that drains off a land surface from rainfall before it reaches a natural water body. There’s an important distinction between stormwater and rainwater. This post takes stock of Los Angeles’ performance in meeting its stormwater capture goals and discusses rainwater capture as another opportunity to enhance local water supply. Officials are making progress, but there’s still a long way to go. These capture efforts are a part of Los Angeles’ scheme to build local water resilience and implement stormwater capture projects throughout the county. The Los Angeles County Public Works Department announced recently that more than 33 billion gallons of stormwater have been captured in the early months of the winter storm season, which will be enough to supply 816,000 people with enough water for an entire year. A very full Ballona Creek after a rain event earlier this month.Īt least nine atmospheric rivers blasted California between December 20th and January 15th, causing flooding and extensive damage, while also delivering much needed precipitation to our parched state.
