MSD issues a monthly bill to approximately 424,000 commercial and residential accounts. The bill is comprised of a Wastewater User Charge (WW USER CHG). The Wastewater User Charge includes a base charge and a volume charge based on either the amount of water used at an address or, if no water meter is in use, the number of rooms, baths, water closets, and showers in the building. Commercial properties are also billed a Compliance Charge based on the type of wastewater discharged to the public sewer system.
You will notice a change in the wastewater portion of your MSD bill effective on July 1 of each year. The new rate will be reflected on the bill you receive in August. The changes are necessary to meet state and federal environmental regulations that govern the operation of our collection and treatment system. The increases are also necessary to meet the maintenance and repair of the sewer system.
