The city of Carlsbad Nov. 1 celebrated the expansion of its water recycling plant, a project the city says will increase water reliability by enabling companies, schools, HOAs and other large water users to conserve limited drinking water supplies by utilizing recycled water for irrigation and other non-drinking uses. Recycled water is wastewater that has been treated to a level suitable for irrigation, industrial processing and other non-drinking uses. The city has more than doubled its recycled water consumption in the last 10 years and has more recycled water meters than any other water district in San Diego County.
