The El Toro Recycled Water Expansion project, valued at $26 million, will consist of three pipeline projects and one water treatment plant expansion. The existing water treatment plant serves communities in South Orange County, including Laguna Hills and Laguna Woods.
The plant will reduce the demand for imported water by increasing the capacity to treat and distribute recycled water for irrigation and other uses, and the distribution system will allow for increased delivery of recycled water to existing customers.
Construction is to begin early this year, and the project is slated for completion in late 2014. The expansion will produce and deliver approximately 1,400 acre-feet per year of tertiary-treated recycled water over 200 dedicated irrigation meters within the district’s service area. Tertiary treatment is the next wastewater treatment process after secondary treatment. This step removes stubborn contaminants that secondary treatment is not able to clean up. The wastewater becomes even cleaner in this treatment process through the use of stronger and more advanced treatment systems.
