Account Review



Sewer charges are based primarily on the amount of water used at your property. If you have problems with your water system, this can sometimes affect your sewer bill.



If you are an MSD customer who receives their water and sewer bill from Greater Cincinnati Water Works (GCWW) and have experienced a water leak that did not drain into the MSD public sewer, you may eligible for an account adjustment.



If you believe you have experienced a water leak that did not drain into the MSD public sewer, please call Greater Cincinnati Water Works (GCWW) at (513) 591-7700.


After speaking with GCWW, you may be asked to submit an MSD Account Review Form to request a review of your account to see if your bill can be adjusted.


NOTE: In cases of water leaks from toilets or other interior fixtures where the water went down the drain and entered the MSD public sewer system, MSD cannot issue a credit. However, if the leak occurred during the winter period, MSD will review the water consumption to see if it can be adjusted. The winter period is the average amount of water usage from January, February, and March that establishes your maximum water consumption for the next 9 months - April through December. The winter period only applies to single and two-family residential customers.



You must submit your request for an account review in writing, using the MSD Account Review Form along with required documentation (e.g., plumber's bill, photos). We cannot accept requests for reviews over the telephone.
