Water Transmission Pipeline Impressed Cathodic System Upgrade

PROJECT DESCRIPTION

This project will install a new cathodic protection system for the water transmission pipeline under the Petaluma River to ensure the safety and security of this pipeline for years to come.

Cathodic protection is necessary for the protection of steel pipes installed in corrosive and saturated soils. This water main section primarily consists of aging, 34-year-old, steel pipes. To mitigate future catastrophic failures and lower maintenance costs, this project will provide the pipes with cathodic protection. Such protection is expected to last anywhere between 30-40 years and will therefore ensure the integrity of the City’s water distribution system.
