Comprehensive Disinfection Modification - 281236.00 - City of Topeka

The project funds the evaluation of needed disinfection modifications at the Water Treatment Plant previously targeted the addition of powder activated carbon (PAC) and the relocation of chlorine contact basins for the east and west treatment trains. Enhancements of the treatment process have become vital to improve water quality, mitigate the formation of harmful disinfection byproducts, and maintain compliance with regulatory standards. After engineering assessments, the addition of PAC or chlorine contact basin modifications proved exceedingly cost-prohibitive and unsuccessful in seeking regulatory approval for discharge of carbon to the Kansas River. The addition of an ozone disinfection system has been identified as the most beneficial and cost-effective option for the future of Topeka's Water Treatment Plant. As summarized in the 2012 Disinfection Modification study conducted by Black & Veatch, and reinforced in the 2017 Water Treatment Plant Facility Plan Report, ozone addresses all of Topeka's treatment goals including disinfection, reduction in disinfectant byproduct formation, taste and odor control, and treatment of algal toxins. Ozone is operationally less expensive compared to other disinfection or treatment modifications, such as PAC, and provides a much higher water quality to customers. This project will include the complete design and construction of an ozone disinfection facility to the east and west treatment trains. This project is included in the city's FY 2022-2031 Capital Improvement Program. As of July 26, 2022, further details regarding design and construction timelines have not been identified. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
