Less than a month after he began leading the $1.1 billion Public Utilities Department in mid-October, Bianes emailed staffers who were preparing a presentation for one of the water department’s oversight bodies. Bianes said it’d be best to be “vague” and not give the Independent Rates Oversight Committee any specifics about how the department was handling ongoing customer service issues.
