"At Cal Water, we are committed to being a responsible steward of our planet's limited resources through a multipronged approach to efficiency, conservation, and sustainability," said Marty Kropelnicki, Cal Water Chairman and CEO. "An important part of those efforts is our valued partnership with EPA WaterSense®, which helps validate the importance of conservation and bolsters our efforts to help our customers and communities save water every day."
