Questions regarding the transition from NJAW to EWU

Why is transition taking place?

Edison Water Utility is being re-established as a result of passage of a referendum in September 2019 which mandated that the public water distribution system be operated and managed by the Township of Edison.  Effective January 1, 2020 Edison Water Utility will operate and manage the water distribution system that was previously managed by American Water.

Will I continue to be billed with the same frequency?

Residential Customers: Yes, Edison Water Utility will continue to bill on a quarterly basis.

Commercial/Industrial Customers: Yes, Edison Water Utility will continue to bill on a monthly basis.

Will my meter be read with the same frequency?

Meter reads will continue with a similar reading cycle.

Where should I mail my payment?

Commencing January 1, 2020 all payments should be mailed to:

Edison Water Utility
100 Municipal Blvd
Edison, NJ 08817

When will I receive my first bill?

Edison Water Utility will commence reading meters and billing customers as of January 1, 2020.  Edison Water Utility will continue reading your meter using a similar reading cycle; however you may not receive the bill on the same day as you did previously.  The first bill you receive from Edison Water Utility will cover water usage from the last time the meter was read by American Water through the first meter reading performed by Edison Water Utility within your quarterly billing cycle.

Are my rates changing as a result of the transition?

Edison Water Utility rates will remain the same on 1/1/20; however they will be evaluated by the Edison Township Council during 2020.

Questions related to your bill?

As of January 1, 2020 the Edison Water Utility will answer all your questions related to your water billing and customer service questions.  You can direct all your questions to 732-248-6400, visit or email

I was enrolled in American Water Resources Water Line Protection Program.  How will that be impacted?

American Water Resources sent notices to customers who were enrolled in the program in June 2019 letting customers know that their enrollment would be cancelled July 31, 2019.  This notice included information to enroll in a similar program to continue water line protection with American Water Resources Water Line Protection Program.  Any questions, please contact American Water Resources at 888-378-4310.

Maintenance Tips

What equipment is your responsibility?

Much of the equipment we use to provide water is located beneath the ground, and it can be difficult for customers to determine what equipment is their responsibility and what equipment is EWU's responsibility. The following descriptions explain the facilities and equipment used to provide water service from the utility’s water main to your property. The diagrams below detail the homeowner's and EWU's responsibility.

  • Company Service Line. Owned and maintained by the utility, this service line extends from the water main to the curb stop or curb line.
  • Curb Stop. Owned and maintained by the utility, the curb stop is a valve that can be opened and closed to control the supply of water to the property.
  • Meter. Owned and installed by the utility, this device is used to measure water consumption at the customer’s property. Although the meter is owned by the utility, the customer is responsible for providing an adequate location for the meter, making it accessible and assuring that it is protected from damage, including damage caused by freezing.
  • Customer Service Line. Owned and maintained by the customer, this service line extends from the curb stop or curb line to the building.
  • Meter Pit. Owned and maintained by the customer, this structure is constructed by, or for, the customer to house the water meter outside of the customer’s home at an underground location. Customers are responsible for keeping the pit visible and for all the plumbing within the pit. The illustration shows a meter in the home, so the meter pit is not shown.
  • Pressure Reducing Valve (PRV). Owned, installed and maintained by the customer, this device is designed to reduce water pressure within the customer’s home if the pressure of the utility’s distribution system exceeds a certain threshold set by the plumbing code (typically 60 pounds per square inch). Installing a PRV might increase the life of internal plumbing fixtures and piping. A plumber can verify the pressure in your home and determine whether a PRV should be installed as part of your household plumbing.
  • Backflow preventor: Customer owned. When installed, this device is designed to prevent a potential backflow of contaminants from the customer’s property into the utility’s distribution system.

What is a Cross-Connetion and how do I avoid it?

A cross-connection is a point in plumbing systems where drinking water might come in contact with, and be contaminated by, hazardous materials — solid, liquid or gas.

If you leave a hose in non-potable (not fit for drinking) water such as soapy or pool water, you could contaminate your drinking water. For example, if the pressure in the water main feeding your property drops while your hose is submerged in non-potable water, the non-potable water could be sucked back into your pipes or into Aqua’s distribution main.

The Safe Water Drinking Act requires that backflow protection devices be installed on all non-potable water services.

Here are some plumbing tips to help you avoid backflow: 

  • Install backflow-prevention devices on threaded faucets in your home, especially outdoor hose faucets. Inexpensive backflow preventers, like hose connection vacuum breakers, can be found at many local plumbing supply stores.
  • Keep the ends of hoses clear of any possible contaminants. Never leave a hose in a sink, bucket, drain or tub. Also, keep water levels in such items below faucets and inlet valves.   
  • Don’t use spray-device attachments that contain chemicals, such as weed killers, on your hose without a backflow prevention device.
What are some tips to maintain my water heater?

If you’ve been away from your home for a long time, you might want to check your water heater when you return.

Manufacturers recommend periodically flushing sediment from your storage-type water heater. Residents in areas with high mineral content in the water should flush more often.

Most sediment in water heaters develops when minerals settle after the water heats. Sediment in water heaters also can contain sulfur compounds that can cause odors in the water.

Here’s how you can flush sediment from a water heater:

  • Be cautious — the water in the heater might be extremely hot and capable of causing burns.
  • Follow the manufacturer’s instructions for specific procedures on how to flush the water heater. These instructions are generally found in the manual included when the heater was purchased. You might also find them on the manufacturer’s website. If you are unable to find the manual or information on the website, the procedures that follow might work.
  • If you have a gas water heater, set the gas valve to“pilot” to prevent the burners from coming on while you are flushing it.
  • If you have an electric water heater, be sure to turnoff the circuit breakers to the heater. If the water level drops below the heating elements and the thermostat turns them on, the heating elements could be damaged.
  • Connect a garden hose to the drain valve at the bottom of the tank. The water could be very hot — make sure the outlet of the hose is in a safe area away from pets and children.
  • Close the shut off valve on the cold water inlet to the water heater.
  • Carefully open the temperature/pressure-relief valve at the top of the tank by lifting the lever. Leave the valve open.
  • Open the drain valve at the bottom of the heater to allow the water to flow out through the garden hose. If sediment is clogging the drain valve, try closing the temperature/pressure-relief valve and turn the cold inlet valve back on to “power-flush” the sediment.
  • In some cases, the sediment hardens into large chunks that can block the drain valve. If this occurs, wait until the water in the heater has cooled, remove the garden hose from the drain valve, remove the valve if necessary, and use a long screwdriver to break up the clog.
  • When the garden hose runs clear, you’re finished.
  • Close the drain valve at the bottom of the tank and remove the garden hose.
  • Close the pressure-relief valve at the top of the tank if it is still open, and open the hot water faucets in the highest part of the house. Slowly turn on the cold inlet valve for the hot water.
  • Let the hot water faucets run in the house until the air bubbles stop coming out, then fully open the cold water valve to the hot water heater. Make sure your pressure relief valve and drain valve aren't leaking.
  • Turn the heater back on. With a gas heater, relight the pilot light if it has gone out.
Does Edison Water Utility offer service contracts or protection plans for my home?
No. Check with your individual home owner's insurance to inquire if they offer any coverage.  Alternatively, you can perform an internet search for providers of subscription services for your home.

Questions About Water

What is the difference between municipal-owned and a privately-owned system?
Municipal systems are owned and operated by the cities or towns they service and are under the management of the mayor or other elected officials. Privately-owned systems range from small corporate associations that provide service to a dozen families to large corporations that own several water service companies. Whether pubic or private, all water utilities must abide by the strict water quality standards established by the EPA as well as state and local regulations. Private company rates are generally established by state PUCs.
How do I know if my water is ready to drink?
The Safe Drinking Act passed by Congress in 1974 authorized the USEPA to set standards for the water delivered by every community water system in the United States serving more than 25 people. The USEPA establishes national health-based standards for drinking water to protect against both naturally-occurring and man-made contaminants that may be found in water supply sources. Our water utilities perform many tests each day to ensure that our customers receive high-quality drinking water.
How does my water get to the tap?

The water infrastructure system is relatively straightforward. Water travels through three main channels: the pumping station and the distribution system. It then leaves the treatment plant and makes its way, through the network of pipes, to homes and businesses.

Pumping Station
The pumping facility extracts raw (untreated) water from the a source, such as an aquifer or river, using large pumps, pipes, and a power source to drive the pumps.

Treatment Facility
After raw water is pumped from its source, it is sent to a treatment facility, also usually situated above ground. This is where water is treated to meet the levels of purity and quality set forth by the United States Environmental Protection Agency (USEPA). 

Distribution System
Once the water has been treated it is then ready to enter the distribution system. The distribution system is a network of pipes that span fields, mountains, and highways so that it can reach homes, businesses, fire hydrants, and a multitude of other destinations. The U.S. water pipe network stretches across 700,000 miles and is more than three times the length of the National Highway System. 

Who sets the water quality standards?
Water is treated to meet the levels of purity and quality set by the USEPA. Increasingly stringent USEPA regulations require treatment processes to be continually updated and tested, advancing the levels of technology, skill and chemical solutions. Nearly all public water supplies in the United States meet USEPA standards for safe drinking water. Standards limit the concentrations, or amounts, of contaminants. In some cases where a contaminant cannot be measured, water supplies must provide specific treatment, such as disinfection and filtration.
What are some of the costs associated with delivering water?
The cost of water itself is minimal, but there are many expenses associated with the planning, design, construction, operations and maintenance of a water system, as well as the actual treatment process. These include the facilities used to extract, treat and supply the water; investments made to upgrade and maintain these facilities; the materials used in treating the water; updating water testing and treating methods in order to meet regularly with compliance laws; and the labor required to manage the water system. Among the main costs: the electricity used to pump the water from its source and across terrain, and the purchase and operation of pipes.
Where does my water come from?
American Water will remain the supplier of the water.  The will continue to treat and deliver the water from its treatment plants to the Edison Water Utility's distribution system via a network of underground pipes.
