We’re committed to providing residents with a safe and reliable supply of high-quality drinking water. We test water using sophisticated equipment and advanced procedures. The Water, Sewer, Streets Bureau meets state and federal standards for water quality. This annual “Consumer Confidence Report,” required by the Safe Drinking Water Act from the Environmental Protection Agency, tells you where your water comes from, what our tests show about it and other things you should know about drinking water.
