The City of Mitchell would like to remind residents to check their sump pumps to make sure that they are working properly. It is recommended that sump pumps be drained to the curb. Do not drain water in your backyard if possible. That will prevent you or your neighbors from recycling the ground water. Do not drain sump pumps into floor drains or into the sanitary sewer system. This may cause the sanitary sewer system to back up on you or your neighbors.
