Sanitary Sewer

The City of Grimes currently operates and maintains its own wastewater treatment facility and sanitary sewer collection system. The City of Grimes has opted into the Des Moines Metropolitan Wastewater Reclamation Authority (WRA)  which allows for additional sanitary sewer capacity to meet the needs of the growing Grimes community. The City of Grimes plans to deconstruct its wastewater treatment plant after the WRA connection is completed. The purpose of the sanitary sewer collection system is to carry sanitary waste from homes and businesses in Grimes to the WRA’s WRF.
