Where to send your Connecticut Water payment
Connecticut Water Company operates in central and eastern Connecticut and accepts payments through three main channels: online through their website, by phone, or by mail. The fastest way is online at ctwater.com — you can pay immediately with a bank account or credit card, and the payment posts within one business day.
If you prefer to call, Connecticut Water's payment line is available during business hours. Have your account number ready, which appears on your bill. For mail payments, write your account number on the check and send it to the address printed on your bill — typically a lockbox in Connecticut. Mail payments take 7 to 10 business days to post, so send them early if your due date is approaching.
Some customers can also set up automatic payments directly from a checking account, which removes the need to remember a due date. You can arrange this online or by phone.
Key Takeaways
- Connecticut Water payments can be made online at ctwater.com, by phone during business hours, or by mail to the address on your bill.

- Your account number appears on your bill and is required for all payment methods.
- Automatic payments from a bank account eliminate the need to pay manually each month and can prevent late fees.
- If your town has a municipal water system instead of Connecticut Water Company, you will pay through your town's utility office, not Connecticut Water.
Understanding your bill due date and late fees
Connecticut Water bills are typically due 15 to 20 days after the bill is mailed. The exact due date appears clearly on your bill — check the top right corner or the section labeled "Amount Due By." If you miss this date, Connecticut Water charges a late fee, usually around 1.5% of the unpaid balance per month, though the exact percentage may vary.
If you cannot pay by the due date, contact Connecticut Water before the deadline. The company may offer a short extension or a payment plan, depending on your account history and the amount owed. Waiting until after the due date passes makes negotiation harder and triggers the late fee immediately.
What to do if you cannot pay on time
If you are struggling to pay your water bill, Connecticut Water has a Customer Assistance Program that may help. This program is designed for customers with low or fixed incomes and can reduce your monthly bill or help you catch up on arrears. You will need to provide proof of income and household size to be considered.
Contact Connecticut Water's customer service to ask about the program and request an application. Processing typically takes two to four weeks. In the meantime, ask whether the company will pause late fees or collection action while your request is being reviewed — some utilities do this, though it is not may provide.
If you are facing a water shutoff, Connecticut Water is required by Connecticut law to give you written notice at least 10 days before disconnection. This notice will include information about payment plans and assistance programs. Use this time to contact the company and explore your options.
How to read your Connecticut Water bill
Your Connecticut Water bill shows several key pieces of information. At the top, you will see your account number, service address, and the billing period (usually one month). The "Amount Due By" date is your deadline — this is not a suggestion.
The main section breaks down your charges. Most of your bill is the water usage charge, calculated by multiplying the number of gallons you used by the rate per gallon. Connecticut Water uses a tiered rate structure in some areas, meaning the more water you use, the higher the per-gallon rate becomes. Check your bill to see if this applies to you.
Below usage charges, you will see fixed fees such as a service charge or meter fee, which stay the same each month regardless of how much water you use. Some bills also include a stormwater fee if your town participates in that program. Add all charges together to find your total amount due.
Comparing your usage month to month
Connecticut Water bills include a usage history, usually shown as a graph or table on the back. This shows your water consumption for the past 12 months and helps you spot unusual spikes. A sudden jump in usage often signals a leak — a running toilet, dripping faucet, or underground pipe break can waste hundreds of gallons per day.
If your usage is unusually high, check for visible leaks first: listen for running water when nothing is on, look under sinks and around the water heater, and inspect your toilet tank for slow leaks (add food coloring to the tank and see if it appears in the bowl without flushing). If you find a leak, repair it and contact Connecticut Water to report it. Some utilities credit part of the overage if the leak was caused by a faulty meter or company infrastructure.
If you cannot find a leak but usage remains high, request a meter test. Connecticut Water can verify whether your meter is reading accurately. If the meter is faulty, you may receive a credit for overbilling.
Setting up automatic payments and managing your account online
Connecticut Water's online portal lets you view your bill, make one-time payments, and set up automatic payments without calling. To access it, go to ctwater.com and look for "Pay My Bill" or "My Account." You will need your account number and a password you create.
Automatic payments can be set to deduct from your bank account on a date you choose — typically a few days before your due date. This prevents late fees and removes the need to remember to pay each month. You can change or cancel automatic payments anytime through your online account.
The online portal also shows your billing history, usage trends, and any messages from Connecticut Water about your account. If the company needs to contact you about a problem, you may see a notification here before receiving mail.
If you have a different water provider in Connecticut
Connecticut has several municipal water systems and private water companies. If you live in towns like Stamford, Norwalk, New Haven, or Hartford, you likely pay a municipal water utility, not Connecticut Water Company. These towns operate their own water departments and have different payment methods and bill formats.
To find your water provider, check your bill — the company name and payment address will be listed at the top. If you are unsure, contact your town's public utilities department or water authority. They can tell you how to pay and answer questions about your bill.

How do I know if I have a leak?
Check your bill's usage history for a sudden spike. Look for visible leaks under sinks, around the water heater, and in your toilet tank (add food coloring to the tank to test for slow leaks). If you cannot find a leak but usage is high, request a meter test from Connecticut Water.
Can I get my bill reduced if I am on a fixed income?
