In May 2017, San Diego city officials made an important announcement regarding the future of the city’s water supply. According to the San Diego Union-Tribune, the city planned to blend treated sewer water with the regular drinking water supply. Fast forward to 2018 and the project is moving right along. On March 6, the State Water Board announced the approval of new regulations. These detail the use and quality of recycled sewer water that will later blend with surface water reservoirs.
