SAFE and RELIABLE
INFRASTRUCTURE

Providing reliable water and sewer services to customers throughout the YLWD service area requires a complex infrastructure that includes facilities, equipment, and miles of pipeline. In accordance with sound asset management planning, the District’s Capital Improvement Plan (CIP) identifies and prioritizes the construction projects that are required over the next five years. Updates are posted regularly on active construction projects. Click on the projects listed below for specific information.
