In addition to maintaining the current collection system, the Sewer Division helps Engineering Services provide capital improvements that replace deficient pipes and equipment and add system capacity or increase level of service to accommodate a growing population. The Wastewater Master Plan and its CIP identifies and prioritizes needs and construction projects that are funded by sewer utility fees and System Development Charges (SDCs) (collected when building permits are issued). Projects are implemented that protect natural resources and complement the surrounding environment.
