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.
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.
Water Leak, Main Break, Sewer Backup or Stormwater Emergency
Water emergency
Call: 609-989-3222
Use for water running from streets/sidewalks, water main break, service-line leak, pressure issue, no water or after-hours emergency.
Sewer inlets / flooding
For sewer line markout or city sewer inlet flooding, call 609-989-3180 Monday-Friday, 7:30 AM-3:30 PM.
Problem |
Say this when calling |
Safety / next step |
|---|---|---|
Water main break |
“Water is running from the street/sidewalk at [address/cross street]. It started at [time].” |
Stay away from sinkholes, icy pavement, damaged roadways and traffic. |
No water / low pressure |
“All taps / some taps at [address] have no water or low pressure.” |
Check whether neighbors are affected; report if more than one fixture is affected. |
Sewer backup |
“Wastewater is backing up at [basement/floor drain/toilet] at [address].” |
Stop using water; avoid contact with wastewater; keep children and pets away. |
Private sewer line issue |
“City crew checked and said no city-system restriction exists.” |
Call a professional plumber/drain service; property owner is responsible for private line from home to curb. |
Clogged storm drain / inlet flooding |
“The inlet near [location] is blocked and water is ponding/flooding.” |
Do not remove grates or enter floodwater. |
Fire hydrant issue |
“Hydrant at [location] is leaking/damaged/out of service.” |
Do not operate hydrants yourself. Report location and visible issue. |
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. |
