Billing and account research from public material
Provider-specific research notes are displayed separately from fields that contain only an unavailable-information marker. Read qualifiers in each note and verify current account terms with the provider.
- Billing frequency
- Monthly for the standard 5/8-inch residential customer service charge and ordinary water billing; some larger-meter rate tables include quarterly billing schedules. The individual account statement controls the actual due date and frequency.
- Rate structure
- Uniform volumetric water use charge of $3.91 per CCF in 2026, where one CCF is approximately 748 gallons, plus fixed meter-size customer-service charges. Member-town sewer operations are primarily supported through municipal ad valorem property taxation, with a $12.50 monthly sewer customer-service charge and a $4.87-per-CCF Clean Water Project charge for applicable customers; non-member towns may add fixed capital surcharges.
- Residential cost reference
- For a representative 5,000-7,000 gallon month, approximately 6.7-9.4 CCF at $3.91 is $26-$37 for water use. Adding the typical $15.73 monthly water customer-service charge, $12.50 sewer customer-service charge, and about $32.55-$45.58 in Clean Water Project charges produces roughly $87-$110 before any member-town property-tax sewer component, non-member surcharge, meter-size difference, or other assessment.
- Wastewater and sewer calculation
- MDC water use is read at the meter and charged per CCF. For member towns, much of standard sewer operations is recovered through an ad valorem charge on the municipal property-tax bill, while the MDC bill carries the $12.50 monthly sewer customer-service charge and applicable Clean Water Project charge based on CCF. Non-member customers may pay a separate $15.73 monthly non-member charge and town-specific capital-improvement surcharge; the reviewed MDC materials do not use a winter-average formula.
- Meter reading
- MDC has moved from manual reading to automated reading using a low-powered radio signal from the meter to a drive-by MDC vehicle. The RF device reduces property access and estimated bills; if the system fails or becomes obsolete, bills are estimated from the last actual reading until an updated device is installed. The reviewed pages do not promise hourly transmission or a universal calendar-day read schedule.
