San Diego accelerates construction of water recycling system: Pure Water San Diego.

August 4, 2016

  • In November 2014 the San Diego City Council unanimously approved plans to recycle sewage into drinking water.


  • What is the process? First, a system of plastic tubes and straws filter microbes and contaminants. Second, the water undergoes reverse-osmosis to screen organic material, salts and solids. The final step includes exposing the water to ultraviolet light and hydrogen peroxide to kill any remaining toxins.


  • The City Council recently announced the acceleration of its construction of the water recycling system - 30 million gallons of sewage a day will be recycled by 2021 instead of 2027.


  • Recycled water will be pumped into the Lake Miramar reservoir and the purification plant will use methane from the Miramar landfill as its power source.


  • The first phase will cost $1 billion.
