The City of Fayette’s wastewater treatment facility (WWTF) did not meet current DNR ammonia limits for wastewater effluent. With IIW’s design expertise, the City of Fayette was able to meet the DNR limits with a 2015 lagoon upgrade and headworks improvement.
The Headworks Building Improvements included replacing equipment for flow measurement, fine screening, grit removal, and pumping prior to flow delivery to the WWTF. Other aspects of the project included construction of a new blower building, including blowers for the aeration system; new chemical feed building, including equipment and appurtenances for both gas chlorine and sodium bisulfite; new chlorine contact tank; new recirculation pump station and force main; aeration system replacement of Cells 1 and 2; and installation of a new system for Cell 4. The construction of the buildings included electrical and HVAC along with other various items. The project also included improvements to process piping and structures, and the addition of an emergency liquid propane fueled generator with various electrical improvements.
The project was partially funded by a Community Development Block Grant issued by the United States Department of Housing and Urban Development as administered by the Iowa Economic Development Authority.
