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. Cambridge Water Department and the Tax Collector's Office issue quarterly water bills, and bills are due within 30 days of the billing date.
- Rate structure
- Annual-consumption block rates measured in hundreds of cubic feet (CCF), with separate water and sewer rates. FY26 rates effective for consumption as of April 1, 2025 are $3.84/$4.10/$4.36/$4.63/$5.03 water and $17.12/$18.10/$19.45/$20.93/$22.25 sewer across the five annual blocks, with 100 cubic feet approximately 748 gallons.
- Residential cost reference
- Approximately $173 per month for a 6,000-gallon-per-month home using the FY26 annual block schedule, before any other municipal charges: 72,000 gallons is about 96.3 CCF annually, producing approximately $31.90/month water and $141.20/month sewer when the first 40 CCF use block 1 and the remaining annual usage uses block 2. Actual quarterly bills, meter class, and current rate-year changes may alter the total.
- Wastewater and sewer calculation
- Water and sewer charges are shown on the same bill where applicable. The City applies the same annual-consumption block concept to sewer, so the annual CCF usage moves through sewer rates separately from water rates; the FY26 sewer rates are $17.12 for block 1, $18.10 for block 2, $19.45 for block 3, $20.93 for block 4, and $22.25 for block 5 per CCF.
- Meter reading
- Cambridge's Administration Division installs and maintains Automated Meter Reading (AMR) devices and issues high-read notifications. Bills show previous and current meter readings and a read code; meters are read for quarterly billing. The City does not describe hourly AMI transmission in the reviewed pages.
