Planning Pipeline Improvements for Aging Water Distribution Infrastructure

Many of the older potable water pipelines in the City of San Diego's system are made of cast iron or steel and have been in service for nearly 100 years. The Otay II Pipeline, consisting of approximately 16 miles of welded steel pipe and 3 miles of cast iron pipe, has been in service for 70 years and supplies water to the Otay service area. In spite of its age, a recent investigation by the City Engineering Staff shows that most of the pipeline is in good condition. However, some isolated sections are significantly corroded and require improvement or replacement. Planned pipeline maintenance and replacement is currently modeled by the CIP Planning Section determining the best and most efficient water transmission system to provide continued water service with minimal interruption during pipeline improvement or replacement projects. This paper presents how the CIP Planning and Engineering Sections worked cooperatively to devise the best management practice and plan for the Otay II Pipeline Improvements Project.
