Consumption Rates

MWRD charges for water used and wastewater treated. Wastewater consumption is based on water consumption as measured by the water meter. Beginning July 1, 2017 MWRD changed the measurement unit for billing consumption from cubic feet to gallons. Our rates have not changed. Residential customers using 5/8” meters will pay the same amount this year as last for their combined water and wastewater usage.

Our water consumption rate is $3.66 per 1000 gallons. This rate correlates to our old rate of $2.74 per 100 cubic feet.

Our wastewater treatment rate is $5.67 per 1000 gallons. This rate correlates to the combined former rates of $3.34 wastewater and $.90 O&M fee per 100 Cubic feet.
