The Edward C. Little Water Recycling Facility (ECLWRF) is the largest water recycling facility of its kind in the United States. It is the only treatment facility in the country that produces five different qualities of "designer" or custom-made recycled water that meet the unique needs of West Basin's municipal, commercial and industrial customers. The facility produces 40 million gallons of water every day, conserving enough drinking water to meet the needs of 80,000 households for a year. West Basin's Water Recycling Facility also houses a 60,000 square foot solar power generating system that has reduced emissions of carbon dioxide by over 356 tons in one year's time.
The tour will follow the treatment processes of this facility for the five types of water it produces:

  • Tertiary Water (Title 22) for a wide variety of industrial and irrigation uses;
  • Nitrified Water for industrial cooling towers;
  • Softened Reverse Osmosis Water: Secondary treated wastewater purified by micro-filtration (MF), followed by reverse osmosis (RO), and disinfection for groundwater recharge;
  • Pure Reverse Osmosis Water for refinery low-pressure boiler feed water; and
  • Ultra-Pure Reverse Osmosis Water for refinery high-pressure boiler feed water.

The bus will depart from the LAX Hilton Hotel at 1:30 and return by 4:30.

What to Wear: All participants must wear closed toe shoes and pants and be able to walk without assistance and climb stairs. Anyone in shorts, dresses, or high heels will not be allowed to tour.
