Past Due, Shutoff Risk or Reconnection Concern

High Aquarion Water Bill: Leak and Usage Checklist
Toilet leak
Aquarion says a leaky toilet can waste 200 gallons per day — about 50 extra flushes per day.
Small leak
A dripping faucet or small leak can waste up to 60,000 gallons of water per year if not fixed.
Usage history
Use My Account to view water consumption history before disputing a high bill. Usage spikes are more useful than dollar amounts alone.
Turn off all water use
Turn off faucets and water-using appliances such as dishwashers and clothes washers.
Find the water meter
Inside meters are often in a basement, crawl space, or utility room. Outside meters may be in a covered pit in front of the home.
Watch the tell-tale indicator
If the red tell-tale indicator moves while all water is off, Aquarion says you probably have a leak.
Compare two readings
If there is no tell-tale indicator, compare meter readings over 30–60 minutes while no water is being used.
Start, Stop Service or Real Estate Closing
Buying or selling
Use Aquarion’s real estate closing process. The request must be completed and received at least 10 business days before property closing.
Final bill handling
Aquarion prepares and emails final water/wastewater bills. In Connecticut, final meter reading may be estimated unless actual reading is provided or there have been two or more estimates.
Tenant service
For water accounts only, residential or commercial tenants can apply for service. For wastewater customers, the start/stop process is for property owners.
Aquarion Utility Scam Warning
Do not panic-pay
Aquarion says representatives never ask for instant payment in person or over the phone and do not require prepaid debit cards.
Check ID
Aquarion representatives carry company-issued photo identification and contractors carry work documentation.
Verify directly
If something seems suspicious, hang up and call Aquarion at 1-800-732-9678. Also report suspicious activity to local law enforcement.

State-Specific Aquarion Tips That Prevent Payment Problems
