Salina study session outlines aging distribution system, rising replacement costs and next steps
Summary
City staff described decades-old cast-iron mains that are causing "red water" complaints, presented maps showing concentrated calls in northern and western neighborhoods, and said rising unit costs and limited bidders mean the city may need larger projects or rate adjustments to accelerate replacements.
The Salina City Commission on July 1 heard a staff briefing on the citys water-distribution system, including the history of pipe materials, recent testing results and options for replacing aging mains.
Martha Tasker, director of utilities for the City of Salina, told the commission the city has more than 340 miles of pipe, much of it cast iron installed in the 1940s—1960s. "We have a red water problem in our old cast iron pipe. That's fact," Tasker said, noting staff have replaced roughly 44 miles of pipe and spent just under $30 million on main replacement since 2010.
Tasker and City Manager Jacob Wood also framed the fiscal context: the water and wastewater system is an enterprise fund supported by user fees, and staff try to avoid steep annual rate hikes. Wood said the city has invested "over a $100,000,000 on the water system in the last 10 or 15 years," but that further replacement competes with other system needs such as treatment-plant work.
Staff presented heat maps built from customer complaint logs and main-break records showing clusters of water-quality calls in the western portion of the city and the North 9th corridor. Tasker said the city uses calls and hydraulic modeling to prioritize which mains to replace, and that the mix of on-site private service-line materials complicates both field diagnosis and federally required lead-line inventories.
The commission directed staff to return with more detailed cost estimates and a recommended project scope; staff said they will also continue exploring construction methods and contractor interest to determine whether larger bundled projects or debt financing could accelerate replacement.
