Trenton vs Township Customers: Why Bills Work Differently

City of Trenton properties

  • City bills water and sewer for properties inside Trenton.
  • Water and sewer appear on the regular quarterly water bill.
  • Charges are assessed against the property, not only the individual customer.
  • Nonpayment can lead to termination and a lien against the property.
  • Real-estate buyers should check balances before closing.

Township service-area customers

  • TWW provides water to parts of Hamilton, Ewing, Lawrence and Hopewell Townships.
  • Suburban municipalities bill separately for sewer usage.
  • Water charges are assessed against the account customer.
  • Water service can be terminated for nonpayment.
  • Charges follow the individual customer in the suburban townships.
Closing/title script: “I’m checking water/sewer status for [property address]. Is this a City of Trenton property or township water-only account? Please confirm unpaid balance, lien risk, final read needs, and whether sewer is billed separately.”

Start, Renew or Change Water Service

New / renewed service

  • Call 609-989-3824 for new water service or renewal questions.
  • Use the official Water Service and Meter Installation Application.
  • Prepare billing name, address, city/state/ZIP, email and phone.
  • Prepare service/meter location and municipality: Trenton, Ewing, Hamilton, Lawrence or Hopewell.
  • Identify service type: single-family, multi-unit, commercial or industrial.

Meter / contractor details

  • Application asks for plumber/contractor name, email and telephone.
  • Application includes service, meter, fireline and irrigation line sizes.
  • Meter Office: 609-989-3225.
  • Construction & Maintenance: 609-989-3222.
  • Engineering Office: 609-989-3822.

Well-water warning

If an applicant is currently served by a well, the application explains well-disconnection responsibilities and notes noncompliance with NJDEP Safe Drinking Water Act requirements can result in a fine up to $5,000.

Do not self-start service: the application states that water service is not received until the Meter Office installs the meter and Trenton Water Works establishes service. Water service established by anyone else may be treated as theft of service.

2026 Trenton Water Rates: What Changes and When

2026 timing: TWW announced that new water rates begin implementation on October 2, 2026. Not every customer will see the new rate immediately because bills update by regular billing cycle across the five-municipality service area.

2026 rate item
Amount announced
What it means for customers
Common residential quarterly fixed service charge
$83.20 for 5/8-inch and 5/8-inch x 3/4-inch meter sizes.
This is the fixed quarterly base before usage charges.
Water consumption, first 15 CCF per quarter
$2.22 per CCF.
Typical residential customers are often within this first tier.
Water consumption above 15 CCF per quarter
$3.33 per CCF.
Higher usage, leaks, irrigation or large households can push into this tier.
Typical residential example
About $109.84 per quarter for roughly 12 CCF.
Use as a rough comparison, not a promise for your exact bill.
Why rates are changing
Funding supports infrastructure, lead service line replacement, treatment facilities, reliability, compliance and customer-service improvements.
Expect the bill design and billing cycles to roll out over several weeks.
Capital plan context
TWW references a $763 million Capital Improvement Plan.
Projects include reservoir, pumping station, lead line replacement, mains, valves, filtration plant and smart meter technology.

Bill of Rights Consumer Rights NJ SHARES Call Customer Care

High Bill, Estimated Read, Meter Test or Hidden Leak

Check bill first

  • Compare CCF used this quarter against the last normal quarter.
  • Check whether the bill is estimated or actual.
  • Separate water, sewer, past-due balance, fees and payment-plan amounts.
  • City properties may include sewer on the water bill; township sewer may be separate.
  • Check whether the October 2026 rate rollout affected your billing cycle.

Check common causes

  • Running toilet.
  • Outdoor hose or irrigation.
  • Water heater, boiler or humidifier leak.
  • Service-line leak between building and curb.
  • Multi-unit dwelling usage or tenant-side plumbing problem.

Your rights

  • You have the right to a prompt complaint review.
  • You may ask the BPU to investigate utility complaints.
  • You have the right to a free meter test once a year if you suspect it is not working properly.
  • You have the right to a diversion-of-service investigation if consumption is unexplainably high.
  • Keep all bills, photos, repair receipts and meter readings.
High-bill script: “My TWW bill increased from [normal CCF/amount] to [new CCF/amount]. Was the reading actual or estimated? I checked toilets, outdoor taps, water heater and visible plumbing. Can you explain the water/sewer lines and tell me whether a meter test or diversion-of-service investigation applies?”
