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
- Quarterly; residential bills are issued four times per year under the FY27 schedule. Bills are typically sent within 10 business days of the billing date, and payment is due 45 days from that billing date.
- Rate structure
- Increasing block tiers billed per CCF/HCF, with separate water and sewer volumetric charges and meter-size base charges. Under the FY27 schedule, residential quarterly tiers are 0-9 CCF, 10-18 CCF, and over 18 CCF; FY27 rates are $8.40, $10.50, and $12.59 per CCF for water and $14.16, $17.97, and $21.57 for sewer.
- Residential cost reference
- At 6,000 gallons (about 8.02 CCF) in a 5/8-inch residential account, the FY27 first-tier combined charge is approximately $180.93 per quarterly bill plus $45 in quarterly water/sewer base charges, or about $225.93 quarterly and $75.31 per month equivalent. Actual bills vary by district schedule, meter read, and any additional municipal charges.
- Wastewater and sewer calculation
- Sewer is calculated from the same metered water volume in CCF, not from a separate household wastewater meter. For FY27 residential quarterly billing, the sewer component is $14.16 per CCF for 0-9 CCF, $17.97 for 10-18 CCF, and $21.57 above 18 CCF, plus a meter-size sewer base charge; no winter-average cap was described in the reviewed rate schedule.
- Meter reading
- Somerville is replacing meters with smart water meters and automatic reading devices, with WaterScope access for usage monitoring and leak detection. The reviewed materials do not state a fixed transmission interval or universal monthly read date; residential billing is quarterly under the current schedule.
