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 and the Tax Collector's Office issue water bills quarterly, and bills are due within 30 days of the billing date.
- Rate structure
- Increasing block rates per CCF, where one CCF is approximately 750 gallons. FY26 rates are $3.84/$4.10/$4.36/$4.63/$5.03 for water and $17.12/$18.10/$19.45/$20.93/$22.25 for sewer across five quarterly-consumption blocks.
- Wastewater and sewer calculation
- Cambridge applies the same quarterly CCF block concept to sewer, with higher wastewater rates by block; the reviewed public page did not state a winter-average cap or a flat percentage tie-in.
- Meter reading
- Cambridge identifies meter-reading/service-call support at 617-349-4771, but the reviewed page does not identify one universal AMI/AMR vendor or transmission interval.
