The Sedalia Lift Station and Force Main to Plum Creek Water Reclamation Authority (PCWRA) Project will improve water quality, fuel high quality economic development in a key corridor, allow CRW to capture reuse water supplies, create economies of scale, and support existing employers.
This project is to design and build the main wastewater conveyance system for Sedalia and the surrounding area. The project is funded by the American Rescue Plan Act (ARPA) through Douglas County with CRW acting as the Project Manager for the project and eventually owning and operating the system for the benefit of the community. Douglas County has approved the project award and agreement with S.J. Louis Construction, Inc.
The construction delivery method for the project is a Progressive Design-Build method. Phase 1 of the project includes a work product up to 60% design which is the basis for this Agreement. At 60% design, a Guaranteed Maximum Price or a lump sum price is negotiated and CRW has the option to accept either for the completion of the project. A Phase 2 Agreement is then negotiated for final design and construction. This Phase 2 Agreement will need to be approved by Douglas County and by Town Council. The entire project is scheduled to be completed by December 31, 2026.
