Somerville Quarterly Water and Sewer Billing Schedule

Somerville moved water and sewer accounts to quarterly billing as of November 1, 2025. Bills are generally sent within 10 business days of the district billing date and are due 45 days from that billing date.

District 1 FY27 bill dates July 15
October 15
January 15
April 15
District 2 FY27 bill dates August 15
November 15

District 3 FY27 bill dates September 15

Find the correct district: Use the account-number search or district map on the official quarterly billing page. Most nonprofit accounts are placed in District 4 regardless of location, so the account number is more reliable than the street alone.
Interest starts after the due window: The City says interest begins when payment is not received by the 45th day. Use the exact bill date and due date printed on the current statement.

Somerville FY27 Residential Water and Sewer Rates

Residential quarterly usage is billed in CCF. One CCF equals 100 cubic feet, or about 748 gallons. The combined rate includes separate water and sewer components, and a fixed quarterly base charge is added according to meter size.

Tier 1: 0-9 CCF $22.56 combined per CCF
Tier 2: 10-18 CCF $28.47 combined per CCF
Tier 3: over 18 CCF $34.16 combined per CCF
Residential quarterly tier Water rate per CCF Sewer rate per CCF Combined rate per CCF
Tier 1: 0-9 CCF $8.40 $14.16 $22.56
Tier 2: 10-18 CCF $10.50 $17.97 $28.47
Tier 3: over 18 CCF $12.59 $21.57 $34.16

FY27 Quarterly Base Charges

Meter size Water base Sewer base Combined quarterly base
5/8 inch$15$30$45
3/4 inch$22.50$45$68
1 inch$37.50$75$113
1 1/2 inches$75$150$225
2 inches$120$240$360
3 inches$326.25$653$979
4 inches$562.50$1,125$1,688
6 inches$1,200$2,400$3,600
8 inches$2,100$4,200$6,300
Simplified 9 CCF example Nine CCF equals about 6,732 gallons. At the Tier 1 combined rate, usage is $203.04. Adding a $45 combined base for a 5/8-inch meter gives an estimated quarterly total of $248.04 before interest, adjustments or other account items.
Why a quarterly total looks larger The bill covers roughly three months, includes both water and sewer, applies a fixed base charge and moves higher consumption into more expensive tiers.
Read Code, meter and prior balance

How to Review a Somerville Water Bill Before Disputing It

Billing district and service period Confirm the district, billing date and usage dates. Compare quarterly usage rather than comparing the total with an older four-month or two-month bill.
Read Code E An E in the Read Code column means the bill used an estimated reading because meter equipment was not transmitting the reading automatically.
Actual reading after meter replacement The old meter may have continued measuring usage accurately even when the transmitter failed. The first bill after replacement can show a charge or credit that reconciles earlier estimates.
CCF usage One CCF is about 748 gallons. Multiply the units by 748 when you need to compare billed use with household gallons.
Water and sewer rates Check both components and the tier. Sewer is a substantial part of the combined per-CCF amount.
Base and prior account items Add the meter-size base charge, then check interest, credits, prior balances, payment posting and approved adjustments.
Meter-replacement back payment: When estimated billing caused underpayment, the City says the next available bill can include the back amount. Customers who cannot pay in full may ask about spreading it across multiple bills for up to one year, subject to 1.17 percent monthly interest, equal to 14 percent annually.
WaterScope and leak investigation

What to Check When a Somerville Water Bill Is Too High

Compare the correct billing periods. A quarterly bill should be compared with another three-month period, not a former monthly or triannual total.
Check the Read Code. An estimated reading or the first actual reading after meter replacement can create an unexpected charge or credit.
Review WaterScope data and alerts. WaterScope can show usage, suspected leaks, high-use patterns, custom consumption notifications and pipe-temperature warnings.
Test every toilet. Put food coloring or a test tablet in the tank. If color appears in the bowl after about 10 minutes without flushing, the toilet is leaking.
Inspect faucets, showerheads, pipes and outdoor fixtures. Look for dripping, wet fittings, running irrigation, exterior spigot problems and signs of frozen or damaged pipes.
Document the evidence before contacting the City. Save WaterScope screenshots, meter photos, the bill, plumber invoices, repair dates and a concise explanation of the disputed usage.
WaterScope opt-in: If a recently replaced meter does not yet have a WaterScope login, complete the City opt-in form and email it to water@somervillema.gov or deliver it to 17 Franey Road.

Bill dispute and abatement rules

When Somerville Will Consider a Water and Sewer Abatement

A high bill does not automatically qualify for an abatement. The City policy focuses on City equipment found to be faulty and specifically excludes many customer-side plumbing and usage problems.

Abatement point City policy Practical action
Submission deadline The request must be received within 45 days of the bill issuance date. Do not wait for another quarterly bill before filing.
Possible qualifying ground Faulty City equipment can support an abatement. Include meter findings, City inspection details and supporting documentation.
Grounds normally denied Leaky toilets, broken boilers, HVAC failures, willful waste, faulty plumbing and construction are listed as denied grounds. Fix customer-side problems quickly, but do not promise that a repair creates abatement eligibility.
Account status The account must have been current before the disputed billing period, except for a pending disputed charge. Provide payment history or proof that earlier charges were paid.
Initial review The City reviews the submitted form and supporting documents within 30 days. Keep a dated copy of the submission and all attachments.
If the request is not supported The customer may be offered an in-person hearing; the policy says a hearing is scheduled within 15 days after the hearing request is received. Respond promptly and bring the bill, meter evidence and payment history.
Form preparation: The request asks for the account number, property address, requestor name, email, phone, bill number, bill date, reason, supporting documents, signature and application date. Submit it in person, email it to water@somervillema.gov, or mail it to Water and Sewer Department, 17 Franey Road, Somerville, MA 02145.
Needs-based annual program

Somerville 25 Percent Water and Sewer Discount

Review the official water and sewer discount program.

Owner and renter responsibilities

Can a Somerville Landlord Charge a Tenant for Water?

Massachusetts law restricts direct tenant water billing. Somerville’s affordability guidance says a landlord cannot charge a tenant for water unless all required conditions are satisfied.

Required conditions The tenancy began on or after March 16, 2005; a written rental agreement applies; a licensed plumber installed submeters; faucets, showers and toilets meet low-flow requirements; and the landlord received the required approval.
What tenants should request Ask for the written lease term, submeter approval, reading period, rate calculation and a clear copy of the water usage being charged.
Do not use the property owner’s City portal without authority: Tenants should follow the lease and Massachusetts submetering rules rather than attempting to change the City-owned property account themselves.
Property sale and ownership transfer

How to Request a Final Somerville Water and Sewer Bill

Check whether the water meter has been replaced. The City says a new water meter is required to process the final bill. Schedule replacement first when the property still has an older meter.
Submit the request at least three business days before closing. Use the final water bill request form or the City’s online final-sale form.
Pay the $25 final-bill fee. Confirm the current submission and payment instructions on the official form.
Prepare for the final reading. The Water Department normally conducts the meter reading one day before the scheduled closing date.
Watch for the emailed final bill. The applicant receives the completed final bill by email.
Pay the final bill in full. After payment, the Water Department updates the billing information for the new owner.

Common Somerville Water Bill Mistakes

Mistake Why it creates trouble Better action
Paying through DOXO The City says DOXO is not affiliated with Somerville. Use City Hall Systems from somervillema.gov.
Using Citizen Self Service to look for a pay button Citizen Self Service is view only. Use it for history, then pay through City Hall Systems.
Comparing a quarterly bill with an old shorter cycle The total covers a different usage period. Compare CCF per day or another quarterly usage period.
Ignoring an E Read Code A later actual meter reading can create a charge or credit. Check meter replacement status and the reading history.
Submitting a leak-only abatement request The City policy lists customer-side mechanical and plumbing failures among denied grounds. Read the policy and submit only supported facts and evidence within 45 days.
Requesting a final bill too late The request is due at least three business days before closing and may require meter replacement first. Start the process before the closing week.
