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 billing. Mount Pleasant Waterworks calculates residential water and wastewater charges by monthly Residential Equivalent Unit (REU) allowances.
- Rate structure
- FY2026 monthly fixed basic-facilities charge plus increasing-block volumetric rates. One residential REU includes 9,200 gallons per month; regular water is $6.34 per 1,000 gallons through the first 9,200 gallons, $12.68 for 18,401-27,600 gallons, and $19.02 above 27,600 gallons.
- Residential cost reference
- For one in-town residential REU using 7,000 gallons, the FY2026 estimate is approximately $58.23 per month for water plus $87.07 for wastewater, or $145.30 combined before taxes or other services: water BFC $13.85 + 7,000 gallons at $6.34, and wastewater BFC $28.20 + 7,000 gallons at $8.41.
- Wastewater and sewer calculation
- In-town wastewater is billed from water-meter consumption by REU. FY2026 residential wastewater has a $28.20 monthly BFC and $8.41 per 1,000 gallons for the first 9,200 gallons/REU, with excessive-use tiers above that level. Unmetered wastewater is charged a separate $65.53 monthly fee.
- Meter reading
- MPW bills by monthly REU and volumetric consumption, but the reviewed 2026 material does not identify a universal AMI/AMR platform, transmission interval, or detailed route schedule. Customers should request usage history or meter-test information when a bill appears abnormal.
