The city of San Diego has been fielding complaints from some Bay Park residents losing sleep over its water project. The first phase of Pure Water San Diego is under construction overnight at the intersection of Clairemont Drive and Denver Street. … In part of a statement emailed to NBC 7, city spokesperson Tyler Becker says the project “will provide a sustainable, locally controlled water supply” and that overnight construction is “necessary to maintain safety for both the public and construction crews.” Residents question that last one. The whole road is closed day and night.
