Recycled Water

West Basin’s Water Reliability 2020 program is designed to shift our future water supplies to more locally-controlled and reliable sources of water. Nothing is more reliable and sustainable for the planet than recycled water. West Basin’s state-of-the-art water recycling program produces five types of “designer” waters to specifically meet our customers’ needs.

  • Irrigation Water:  Sewer water that has been filtered and disinfected for industrial and irrigation use.
  • Cooling Tower Water:  Sewer water that has been processed to remove ammonia for industrial cooling tower use.
  • Seawater Barrier and Groundwater Replenishment Water:  Sewer water filtered by microfiltration and reverse osmosis membranes and disinfected for use in maintaining a barrier against seawater intrusion and augmenting local well water supplies.
  • Low-Pressure Boiler Feed Water: Sewer water filtered by microfiltration and reverse osmosis membranes for use as low pressure boiler feed water.
  • High-Pressure Boiler Feed Water:  Sewer water filtered by microfiltration membranes and passed through reverse osmosis membranes twice for use as feed water for high pressure boilers.
