Fallbrook PUD Goes With the Maintenance Flow to Provide Reliable Service

Water pipeline blowouts like the one the day before Thanksgiving 2017 at the intersection of Stagecoach Road and Ranchwood Lane in Fallbrook provide periodic reminders about the realities of aging infrastructure.

Preventing these type of emergencies is the driving force behind planned shutdowns at water agencies such as the Fallbrook Public Utility District; investments today will avoid similar emergencies and unplanned water outages in the years ahead.

Many of FPUD’s pipes are more than 50 years old. A pipeline’s life can be 80 to 100 years, but many of the early lines that were installed were not put in at today’s standards and have shorter lives.

In fact, some of the early pipelines installed in the area were originally excavated from March Air Force Base in Riverside County and re-installed in Fallbrook, said FPUD general manager Jack Bebee. Many of these pipelines have reached the end of their useful lifespans.

That’s why FPUD is embarking on a number of prevention, maintenance and improvement projects to safeguard and maintain our pipes and infrastructure. Waiting to fix them after they break isn’t the most cost-effective and convenient way to operate.

“We’re trying to prevent a continued Band-Aid approach,” said Bebee.

Proactive approach prioritizes greatest need first

The shutdowns and retrofits are part of FPUD’s proactive approach to pipeline and valve replacement. By identifying pipes that are in the worst condition, the agency is prioritizing those needing to be replaced first, resulting in fewer pipe failures, blowouts and spills.

As part of its ongoing maintenance program, FPUD has refurbished six of its eight steel tanks over the past several years. It is also working on systematic valve replacement covering the entire community area. Valves are a critical component of water and sewer system infrastructure to limit the size of any shutdown.

Annually, the district also replaces or relines sewer manholes and sewer lines. Some of the manholes date so far back they are made of brick. Only FPUD’s sewer customers pay for sewer improvements, and only water customers pay for water improvements.

All FPUD construction work will be on weekdays between 7 a.m. and 4:30 p.m., with an exception for projects that disrupt businesses. Those projects may be scheduled overnight. FPUD customers will receive both a letter and phone call if the planned shutdown will affect their water service.

Quick Solution Keeps Pipeline Repairs on Track

When Water Authority crews began dewatering part of the region’s pipeline system for a 10-day shutdown in mid-November, they discovered a leaking valve that threatened to disrupt the time-sensitive operation.

At issue was a six-foot diameter valve in the Second Aqueduct that was designed to isolate a section of pipeline so workers could safely make repairs inside a dry section of the massive pipe. Instead, the valve was seeping water, which made it impossible to start the welding work slated for the relining project in Bonsall and Fallbrook.

The leaking valve was installed in 1980 and is at the end of its useful service life. While valve failure wasn’t an immediate threat, staff had to find a quick solution to avoid delays that could have impacted water deliveries to customers.

Each winter, the Water Authority coordinates with its 24 member agencies to schedule pipeline shutdowns when water demands are low so crews can conduct routine inspections and make repairs. Timing is always critical to ensure water agencies have adequate supplies while pipes are offline.

The leaking valve threatened to disrupt this year’s refurbishing plan, forcing the Operations and Maintenance Department to quickly assess several potential solutions, including using absorbent materials such as rice or oats to soak up excess water. The team quickly settled on a strategy to construct temporary dams inside the pipeline and divert the seepage while repairs were made.

First, crews built a dam with 200 sandbags just upstream of the leaking valve, redirecting water into another pipeline and away from the contractor’s workspace. Then, they constructed a secondary wooden dam to collect the trickle of water seeping past the sandbags.

The solution was successfully deployed in less than 48 hours, allowing the welding project to begin on time.
