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.
- Rate structure
- Increasing block tiers measured in HCF/CCF. The Town’s published rate materials identify Tier One, Tier Two, and Tier Three water rates, with a separate sewer charge and an irrigation-meter option that is charged water only.
- Residential cost reference
- The Town says an average residential water/sewer bill can be estimated using 15 units, where one unit is 100 cubic feet, multiplied by the number of residents during the billing period. The reviewed current rate page is image-based and does not expose a reliable 5,000-7,000-gallon 2026 total.
- Wastewater and sewer calculation
- Lexington purchases water from MWRA and pays MWRA for sewage treatment and disposal. Residential sewer is billed as a separate tiered charge based on metered water consumption; a second irrigation meter can isolate outdoor use so that only the water rate, not sewer, is charged for that meter.
- Meter reading
- The Town is replacing water meters, but the reviewed pages do not identify a universal AMI/AMR platform or exact reading/transmission schedule.
