Where to pay your Pennichuck bill
Pennichuck Water Works serves parts of southern New Hampshire, primarily around Nashua and surrounding towns. You can pay your bill online through their customer portal, by phone, by mail, or in person at their office. The fastest route is their website at pennichuck.com, where you can set up a one-time payment or enroll in autopay.
If you prefer not to use the internet, you can call their customer service line during business hours to make a payment over the phone using a debit or credit card. Mail payments should be sent to the address printed on your bill — Pennichuck includes a return envelope with most statements. Payments by mail typically take 7 to 10 business days to post to your account, so plan ahead if your due date is approaching.
In-person payments are also an option if you live near their main office in Nashua. Check your bill or their website for current office hours and location before visiting.
Key Takeaways
- Online payment through pennichuck.com is the fastest method and posts to your account within one business day.

- Mail payments take 7 to 10 business days, so send them at least two weeks before your due date to avoid a late fee.

- Late fees typically begin accruing after your due date, so confirm your payment has posted before assuming you are clear.
Setting up online payment and autopay
To pay online, visit pennichuck.com and look for the "Pay My Bill" or "Customer Portal" link on the homepage. You will need your account number, which appears on your bill statement. Create a login if you do not already have one, then enter the amount you want to pay and your payment method.
Autopay is the easiest way to avoid late payments. During the online payment process, you can choose to enroll in automatic monthly payments. Pennichuck will deduct your bill amount from your bank account or card on or shortly after your due date each month. You can change or cancel autopay at any time through your online account.
If you set up autopay, keep your bill statements so you can track what you are being charged. Occasionally a bill amount changes due to seasonal usage or rate adjustments, and you want to notice if the automatic deduction is higher or lower than expected.
Paying by mail or phone
Mail payments should include your account number and be sent to the address on your bill. Write a check or money order — Pennichuck does not accept cash by mail. Include the payment stub from your bill if possible, as it helps their office match the payment to your account quickly.
To pay by phone, call Pennichuck's customer service number during their posted business hours. Have your account number and payment method ready. A representative will process the payment immediately, though it may take one business day to appear in your online account.
Phone payments typically incur a convenience fee, usually a few dollars depending on the payment amount. Online and mail payments do not carry this fee, so choose those methods if you want to avoid the extra charge.
Understanding your due date and late fees
Your due date appears on your bill statement. Pennichuck typically bills monthly, and payment is due by the date shown. If you pay after that date, a late fee will be added to your next bill. The amount of the late fee varies, so check your bill or contact Pennichuck to learn the exact percentage or dollar amount they charge.
If you are unable to pay by your due date, contact Pennichuck as soon as possible. Some utilities offer short-term payment arrangements or hardship programs for customers facing temporary difficulty. Calling before the due date passes shows good faith and may open options that are not available after a late fee is assessed.
If your account falls significantly behind, Pennichuck may issue a shut-off notice. The notice will state how many days you have to pay before service is disconnected. Water shut-offs are serious — reconnection fees apply, and you lose access to water for essential needs. Prioritize bringing your account current if you receive this notice.
Reading your bill and tracking usage
Your Pennichuck bill shows your account number, service address, current charges, and the amount due. It also displays your water usage for the billing period, usually measured in hundreds of gallons or cubic feet. Compare this month's usage to previous months — a sudden spike may indicate a leak.
If you notice an unusually high bill, check for running toilets, dripping faucets, or leaks under sinks and in your basement. A small leak can waste hundreds of gallons per month and inflate your bill significantly. If you cannot find the source, contact Pennichuck to request a meter check or leak investigation.
Your bill may also include separate line items for water service, sewer service, and stormwater fees, depending on your location. Each has its own charge, and all are due by the same date. Make sure you understand what each charge covers so you can spot billing errors.
What to do if you cannot pay on time
If you are facing hardship, contact Pennichuck's customer service before your due date. Explain your situation and ask whether they offer payment plans or extended due dates. Some utilities will work with customers to spread a large bill over two or three months rather than shut off service immediately.
You may also be able to find assistance through local community action agencies or non-profit organizations in New Hampshire that help with utility bills. These programs vary by town and funding availability, so search online for "[your town name] utility assistance" or call your local town office for referrals.
If you receive a shut-off notice, you typically have 10 to 14 days to pay or arrange a payment plan before service is disconnected. This is your final opportunity to act — after disconnection, reconnection fees and deposits apply on top of your unpaid balance.
Frequently Asked Questions
How long does an online payment take to show up in my account?
Online payments through pennichuck.com usually post within one business day. If you pay late in the day or on a weekend, it may not appear until the next business day. Check your online account to confirm the payment has posted before assuming your bill is paid.
Can I set up autopay if I do not have a bank account?
Autopay typically requires a bank account or debit card. If you do not have either, you can pay by phone with a credit card, by mail with a check or money order, or in person at Pennichuck's office. Phone payments do carry a convenience fee.
What happens if I pay my bill late?
A late fee will be added to your next bill. If your account remains unpaid for several weeks, Pennichuck will issue a shut-off notice. The notice gives you a set number of days to pay before water service is disconnected. Reconnection requires payment of the full balance plus a reconnection fee.
Is there a way to lower my water bill?
Check for leaks — a running toilet or dripping faucet can waste thousands of gallons per month. Fix them promptly. You can also reduce usage by taking shorter showers, fixing leaky outdoor faucets, and running full loads in washing machines and dishwashers. Some areas offer rebates for water-efficient fixtures; contact Pennichuck to ask.
Can I dispute a charge on my Pennichuck bill?
Yes. Contact Pennichuck's customer service and explain the issue. If you believe your meter is reading incorrectly or you were overcharged, they can investigate. Provide your account number and details about the charge you question. Keep your bill statement as documentation.
