A new lawsuit alleges Valley Water CEO Rick Callender pushed to have his agency sponsor the NAACP California-Hawaii State Conference — a private group he personally oversees — with public dollars. The conflict of interest claim comes from a civil complaint filed March 20 by Salena Pryor, an NAACP colleague who worked under Callender in his capacity as the statewide NAACP chapter president. She accuses Callender of demeaning and undermining her on numerous occasions while she helped coordinate NAACP events, from distressing late-night video calls to public embarrassment. It comes as Callender is on administrative leave from Valley Water — which cares for Santa Clara County’s streams, flood protection and wholesale water supply — while the agency investigates an employee’s misconduct complaint against him.
