  • New Local regulations since 2006 IRP adoption.
  • In addition to structural best management practices that will remove trash and bacteria, the project will also restore the creek and expand the adjacent park, which will improve the quality of life for both the local residents and native wildlife living close to North Atwater Creek.
  • A pair of 1 million gallon underground cisterns have been constructed to collect and clean storm water and street run-off before it heads into the nearby Arroyo Seco.
    Cisterns will help clean up the water that enters the Arroyo Seco and store water that will be used to help irrigate the park above through an underground, drip-irrigation system
  • Pictured: South L.A. Wetlands
  • Each Document has its own extensive Executive Summary
    Develop cost-effective options for offsetting an additional 39,000 AFY of recycled water by 2035 to reach 59,000 AFY.
    Two legs:
    1. Groundwater Replenishment
    - Treatment Pilot Study was done
    2. NonPotable Reuse (Purple Pipe)
    Identify options to maximize reuse beyond 2035.

    Future Potable Reuse Alternatives
    One Acre Foot is roughly the size of a football field filled with water 1 foot deep.
  • The Advanced Water Purification Facility for Ground Water Recharge at Hansen Spreading Grounds.
  • Outline is the Upper Los Angeles River Area
    Light Blue is the City of Los Angeles groundwater region
    Brown area is general area of groundwater contamination
    Colored shapes are DWP well fields
    Accelerated groundwater clean up is an integral part of LA future water supply and would be implemented regardless GWR approval
