Project Overview

The Upas Street Pipeline, Park Boulevard Pipeline and 5th Avenue Pipeline are more than 70 years old and are reaching the end of their useful lifecycle. They are badly deteriorated and have a recent history of leakage and pipe breaks.

The Upas Street pipeline also crosses vast open space areas that are difficult or impossible to access for routine maintenance and repairs, and has numerous direct service connections that must be relocated to a new, smaller distribution pipeline for consistency with current codes and design standards.

The project will improve water delivery system reliability; increase operational flexibility; reduce overall maintenance needs and costs; and substantially reduce the potential for failure, major pipeline repairs and service shut-downs. The project scope includes:

• Replacing approximately 5.4 miles (28,500 linear feet) of fragile and deteriorating cast iron water mains along Upas Street, Park Boulevard and 5th Avenue, reducing the potential of pipeline failures.
• Replacing Pressure Regulating Stations at West Upas Street and Brant Street; at Upas Street and Hawk Street; and at Upas Street and Park Boulevard, bringing the facilities up to current standards.
• Installing a new Pressure Regulating Station at Upas Street and 7th Avenue, providing operation flexibility and enhancing system reliability.
