Three audits of the city of San Diego’s water department are expected to be released in coming days. Already, though, some members of the City Council are pushing for changes at the department, including the possible removal of top officials who struggled to send out accurate water bills and withheld information from the public and the press. Councilman David Alvarez said he no longer has confidence in the department’s leadership, following an investigation by Voice of San Diego and NBC 7 Responds that showed the head of the department tried to dodge oversight.
