A San Francisco-area water utility is preparing to replace a major pipeline and remove pressure-reducing stations that have been compensating for aging infrastructure for years, part of a broader shift from patching old systems to rebuilding them.

The La Granada Pipeline Replacement Project will eliminate pressure-reducing stations (PRSs), mechanical devices utilities install to manage water pressure when aging pipes can't handle modern demands. Removing them entirely means the utility is replacing the underlying problem rather than continuing to manage it.

The move reflects a calculation utilities nationwide are making: after decades of deferred maintenance, replacing infrastructure outright has become cheaper than perpetually fixing it. The American Society of Civil Engineers estimates a $1 trillion funding gap in U.S. water systems, with 240,000 water main breaks wasting 6 billion gallons of treated water every year.

Federal funding from the 2021 Infrastructure Investment and Jobs Act, which allocated $55 billion for water systems, has made capital-intensive projects like this financially viable. The utility is now seeking a construction manager to oversee the work, indicating the project has moved from planning to execution.

The project number (J-2501) suggests it's one piece of a larger capital improvement program. Eliminating PRSs will reduce energy costs, maintenance needs, and points of failure in the distribution system.

Contractor selection begins soon, with construction expected to follow.
