Dependable, High-Quality Water Service Depends on You

Every day, around the clock, Santa Rosa Water delivers safe, clean, high quality drinking water through extensive infrastructure systems conveniently to your tap. After water is used by homes and businesses and captured in the City's sewer collection system it is conveyed to the City's Laguna Treatment Plant that produced recycled water and biosolids that are beneficially reused.

Changes to Temporary Water Shortage Charges  

A water shortage may be declared when the water supply available to the City is insufficient to meet the normally expected customer water demand at a given point in time. A water shortage may be caused by drought, natural or human caused disasters, climate change, and/or regulatory constraints. The Shortage Plan provides guidance for managing and mitigating water shortages with steps designed to respond to actual conditions and allow for efficient management of limited water supplies in order to ensure water availability for public health and safety needs.
