The City of Hays, Kansas, needed to renovate its Chetolah Creek Water Reclamation and Reuse Facility, originally built in 1953, to replace aging infrastructure and meet stricter discharge limits. With approximately one-third of the facility’s installations having exceeded their service lives, the city turned to CAS Constructors to modernize the facility. The scope included improving the biosolids treatment process, upgrading electrical systems, and expanding the city’s reuse storage capacity, all while adhering to a tight budget.

Challenge met
As part of a design-build joint venture, CAS Constructors presented several value-engineering ideas, ultimately saving the city $4 million.
The new facility was built adjacent to the existing plant, which remained operational throughout construction. The team completed extensive tie-in work, including multiple overnight tie-ins to minimize disruption. The final tie-in required bypassing the city’s flow for a week, which was carefully planned and coordinated with the city and its engineer to ensure all stakeholders were aligned.
Despite near-record rainfall during the project, substantial completion was achieved nearly two months ahead of schedule. The collaborative design-build delivery approach allowed the team to efficiently identify and resolve challenges, resulting in a modern, efficient facility that meets the City of Hays’ water treatment and reuse needs for years to come.
