Western upgrades water delivery to March Air Reserve Base

RIVERSIDE, CA – Western Municipal Water District (Western) recently replaced aging water pipeline along Graeber Street in Riverside, an improvement that is providing more reliable water service to March Air Reserve Base (MARB).

In July, Western replaced about 6,300 feet of aging pipeline, which stretches more than one mile. Notably, MARB relies on this pipeline for fire protection services for most hangers, aircraft operations, flight line protection loops and high value facilities. The new, larger pipeline will ensure the military base gets the optimal water delivery and fire flow it needs for daily and emergency operations. 

“Protecting the integrity of our pipelines is one of the many ways Western is committed to providing high-quality, reliable water,” said Western’s General Manager Craig Miller. “We’re proud of the proactive approach we take to keep our systems in excellent condition. The better our systems work, the better our service will be.” 

The Graeber pipeline project was completed as part of Western’s annual pipeline replacement program. Western’s staff regularly assess the service area pipelines based on their age, material and leak history—and then prioritizes replacements accordingly.  

In this case, the Graeber pipeline was flagged as a priority because it was more than 50 years old and had experienced quite a few leaks over recent years. Western staff performed a hydraulic analysis to study the pipeline’s water pressure—a key element in fire suppression. Through that study, Western staff determined that MARB would in fact benefit from a larger diameter pipeline that would deliver a stronger water pressure to the area. 

“The March Air Reserve Base is an important local economic driver, and Western is honored to support its overall mission and safety,” Miller said. “That’s part of Western’s ongoing dedication to keeping our region strong today and well into the future.” 

The project construction took place along Graeber Street, abandoning the existing pipeline which sat beneath the sidewalk and installing new pipeline in the street—aligning with Western’s current construction standards. The project was completed under the projected $4 million budget. 

“Responsible fiscal stewardship is integral to everything we do at Western, as evidenced by this project,” Miller said. “We’re pleased to deliver this critical infrastructure upgrade to our customers under budget.”
