San Diego Gas and Electric and the city of San Diego are in a disagreement that could be worth up to $120 million. The controversy is over San Diego’s Pure Water project, which would turn sewage into high treated drinking water. The city’s goal is to have a third of its water supply be reclaimed water by 2035.  To accomplish that, the city plans to build a $1 billion pipeline to pump sewage from the Morena area to the North City Water Reclamation Plant on the edge of Miramar.
