Otay II Pipeline Improvements Project
Cast Iron Replacement Phase
Description
Originally installed in 1930, the Otay II Pipeline is one of the City's oldest water transmission pipelines. This 19-mile pipeline conveys water north and south between the Alvarado and Otay service areas. The primary objective of the Otay II Pipeline Improvements Project is to maintain a reliable source of potable water through maintenance, repair, or replacement of the existing pipeline.
A condition assessment and capacity study report prepared in 2000 indicated that some of the sections of the pipeline were in good condition, some needed to be replaced, and some required additional corrosion protection. The study broke the project into eight phases; the Cast Iron Replacement Phase is the third phase of the overall Otay II Pipeline Replacement Project.
Construction Information
The Cast Iron Replacement Phase will install 7,800 feet of new 42-inch welded steel pipe, abandon 1,200 feet of existing pipe, and replace approximately 3,200 feet of existing cast iron pipe with 16-inch PVC pipe.
The new pipeline will run south along 54th Street, between El Cajon Boulevard and Redwood Street. It will also include a small section of Easy Street.
Schedule
Construction crews will begin in the Spring of 2008, and will take approximately two years to complete. Normal working hours will be Monday through Friday, 8:30 a.m. to 3:30 p.m. Night work may occur in some parts of the project area between the hours of 10:00 p.m. and 6:00 a.m. to minimize the construction impact to the community and safety issues.
Cost
The total cost of this project is estimated at $13 million and will be funded by water rates and revenue bonds.
Benefits
- Increase water capacity to meet current and future water needs for the Mid City and Oak Park areas.
- Increased water reliability through pipeline redundancy for the Trojan and Mid City Pipelines.
- Reduce future water main breaks caused by aging pipes.
