What Middlesex Water Company Does
Middlesex Water Company is a private utility that supplies drinking water and wastewater services to parts of New Jersey and Delaware. If you live in their service area, they bill you monthly for the water you use and handle the pipes that bring water to your home and remove wastewater. Unlike a government water department, Middlesex is a regulated private company — meaning the state Public Utilities Commission oversees their rates and service standards, but you deal with Middlesex directly for your account.
The company serves residential customers, businesses, and some municipal systems across central and northern New Jersey, plus a smaller area in Delaware. Your bill covers both water supply and sewer service unless you have a septic system. Understanding how to read your bill, pay on time, and reach customer service will help you manage this utility smoothly.

How to Pay Your Middlesex Water Bill
Middlesex Water sends bills monthly, usually by mail unless you sign up for paperless billing through their website. You have several ways to pay. The easiest is online through their customer portal at middlesexwater.com — you can log in with your account number and pay when ready with a bank account or debit card. There is no fee for this method.
You can also pay by phone by calling their customer service line during business hours and providing your account number and payment method. If you prefer mail, send a check or money order to the address printed on your bill — allow at least 10 business days for it to reach them and post to your account. To avoid late fees, pay by the due date shown on your bill.
Setting up automatic payments is the most reliable way to never miss a due date. Through the Middlesex website, you can authorize them to withdraw the bill amount from your bank account each month on a date you choose. This takes a few minutes to set up and removes the risk of forgetting to pay.
Reading Your Middlesex Water Bill
Your bill shows several pieces of information. At the top is your account number, service address, and the billing period. The main section lists your water usage in gallons for the month, your water charge, and your sewer charge — these are usually separate line items. Below that you may see taxes, municipal fees, or other charges depending on where you live in their service area.
The usage section tells you how many gallons you consumed. Middlesex typically charges a base fee plus a per-gallon rate, so higher usage means a higher bill. If your usage seems unusually high, it may signal a leak — a running toilet or dripping pipe can add hundreds of gallons to your monthly total. The bill also shows your payment due date and the address to mail payments to if you choose that method.
If you have questions about specific charges or want to understand your usage better, you can log into your online account to see a month-by-month history. This helps you spot trends and catch problems early.
Setting Up or Changing Your Account
When you move into a home served by Middlesex Water, you need to open an account in your name. Call their customer service line or visit their website to start service. You will need your service address, move-in date, and a form of payment on file. They may ask for a deposit depending on your credit history — the amount varies, so ask when you call.
If you are moving out, contact Middlesex at least a few days before your departure so they can schedule a final meter reading and close your account. You will receive a final bill for any remaining usage. If you overpaid, they will refund the difference; if you owe more, you will receive an invoice.
You can update your account information — mailing address, phone number, email — through the online portal or by calling customer service. If you want to add a second name to the account or change the primary account holder, call to discuss your options.
What to Do If Your Water Service Is Interrupted
Middlesex may shut off water service if your bill goes unpaid for a significant period, typically 60 days or more past due. Before this happens, you should receive notices in the mail warning you of the risk. If your service is shut off, you must pay the full past-due amount plus any reconnection fee to restore it.
If you are facing hardship and cannot pay your bill, contact Middlesex customer service before your account falls behind. Some customers are able to work out a payment plan — a schedule to pay what you owe over several months rather than all at once. Middlesex may also be able to direct you to local information programs that help with utility bills for low-income households.
If your water stops unexpectedly and you have not received a shut-off notice, call their emergency line when ready. A sudden loss of service may indicate a main break or other problem on their side, and they need to know.
Reporting Leaks and Emergencies
If you suspect a leak in your home — a running toilet, dripping faucet, or wet spot in your yard — fix it as soon as you can. A small leak can waste thousands of gallons per month and spike your bill. If the leak is on Middlesex's side of the meter (their responsibility), call their emergency line and they will send a crew to investigate and repair it at no charge to you.
For water emergencies — no water pressure, a main break in the street, or contamination — Middlesex has a 24/7 emergency line separate from regular customer service. The number is on your bill and on their website. Report the problem with your address and a description of what is happening, and they will dispatch a crew.
If you have a water quality concern — discolored water, unusual taste or smell, or suspected contamination — report it to Middlesex when ready. They test water regularly and take quality complaints seriously. Keep samples if possible and describe when you first noticed the problem.
Understanding Your Service Area and Rates
Middlesex Water serves different communities across New Jersey and Delaware, and rates vary by location. Your specific rate depends on which division of the company serves your address — rates are set by the New Jersey Public Utilities Commission or Delaware regulators and change periodically. You can find your current rates on the Middlesex website or ask customer service to explain the charges on your bill.
The company files rate cases with regulators when it needs to increase rates to cover infrastructure maintenance, upgrades, or other costs. These cases are public, and customers can comment. If you receive notice of a rate increase, the bill will explain what changed and when the new rates take effect.
Your municipality may also add its own fees or taxes to your Middlesex bill — these are separate from the water and sewer charges and go to your local government, not to Middlesex. Your bill will itemize these so you can see what portion goes where.
Frequently Asked Questions
How do I find my Middlesex Water account number?
Your account number appears on every bill you receive, usually near the top. It is also in any welcome letter you got when you opened the account. If you cannot find it, call customer service with your service address and they will look it up for you.
Can I get a copy of an old bill?
Yes. Log into your online account and you can view and print bills going back several years. If you do not have online access, call customer service with your account number and they can mail or email a copy to you.
What should I do if I think my bill is wrong?
First, check your meter reading on the bill against your actual meter if you can access it — meters are usually outside or in a basement. If the reading seems off, call customer service to report it. They can investigate and adjust your bill if an error is found. If you think there is a leak, have a plumber check your home's pipes.
Does Middlesex offer budget billing or level payment plans?
Some utilities offer budget billing to spread costs evenly across the year, but you should contact Middlesex directly to ask if they offer this option. They can also discuss payment arrangements if you are behind on your bill or facing temporary hardship.
Who do I contact if I have a complaint about Middlesex Water?
Start with Middlesex customer service to try to resolve the issue. If you are not satisfied, you can file a complaint with the New Jersey Public Utilities Commission (if you are in New Jersey) or the Delaware Public Service Commission (if you are in Delaware). Both agencies have complaint processes on their websites.
