​Cayce Waterline Replacement Project 


With issues like water discoloration, flow and pressure problems, as well as line breaks, the City of Cayce faced growing challenges with its water system. Much of the infrastructure was built from the 1930s to the 1950s with galvanized, cast iron and asbestos cement piping.

System replacement is often handled incrementally, but since the city qualified for a low-interest State Revolving Fund loan, it created an ambitious $29 million plan, the largest project in the city’s history, to handle all the needed replacements at the same time to minimize the period of disruption. The city also enlisted the Cayce Utility Fund as well as a lease purchase agreement backed by that fund to finance the work.

After two years of design work, construction began in April 2017 and made use of seven contractors. When it completed in December 2018, crews had replaced 262,000 linear feet of existing water lines, 4,000 water meters, fire hydrants and a 1-million-gallon elevated storage tank. The completed project represents 75 percent of the city’s water infrastructure. 

Communication efforts formed a key part of the project, emphasizing that the city wanted transparency and valued business concerns and customer satisfaction. The city’s engineer was contracted to handle all resident communications and complaints. Contracting out for a dedicated customer service phone, email and communication system allowed city staff to continue providing routine services. Councilmembers informed residents and gave updates at neighborhood meetings and community events, and all city staff carried Waterline Replacement Project business cards. 

The success of the project has made an economic development impact. New housing development is taking place, and where people had expressed concern about buying and renting in the city before the project, leaders are reporting that new houses on the market are now finding buyers quickly.
