MSD Residential Bill Charges

Wastewater Service Charge – this is a fixed fee for the maintenance and operation of MSD’s water quality treatment centers.

Wastewater Volume Charge – this charge is based on water consumption as measured on the Water Company meter. A volume rate per 1,000 gallons or CON (Consumption) is the unit of measurement.

Stormwater/Drainage Charge – this fee covers Stormwater, Drainage and Flood Protection Services for the benefit of the entire community. The residential charge is based on one ESU (Equivalent Service Unit), which equals 2,500 square feet of impervious surface—areas such as rooftops and driveways that do not allow water to absorb into the ground.
