Water Treatment & Filtration in Edison, NJ
Central Jersey Water sets up free consultations for Edison homeowners who want cleaner tasting, better feeling water, starting with one question most people never think to ask: which utility actually fills your pipes?
Edison has three water suppliers, not one
Edison is unusual for Middlesex County. Depending on the street, a house may be served by the township-owned Edison Water Utility, directly by Middlesex Water Company, or by New Jersey American Water. Neighbors a few blocks apart can get bills from different companies, and each company publishes its own annual water quality report.
The township utility is fairly new. It was created after a September 2019 referendum directed Edison to take over the distribution system that New Jersey American Water had been running as Edison Water Company. It does not treat raw water itself; it buys from New Jersey American Water's Raritan System and from Middlesex Water, and both of those draw mainly on the Millstone River, the Raritan River and the Delaware and Raritan Canal.
How to tell which one serves your house
The quickest check is the name printed on your water bill. If you pay the township, you are on Edison Water Utility. If the bill comes from Middlesex Water or from New Jersey American Water, you are a direct customer of that company. New owners who have not seen a bill yet can find the supplier in the closing paperwork, or ask the seller which company they paid.
Once you know the name, pull up that supplier's latest report from the links in the box on this page. The numbers there describe the system as a whole. They are a good starting point, but water inside your own walls can still differ because of your service line, your fixtures and how long water sits in the pipes.
Reading the Edison Water Utility report
For calendar year 2024, the township utility reported a highest running average of 1.12 ppm for chlorine, PFOA results up to 6 ppt, PFOS up to 5 ppt, and sodium between 27 and 36 ppm. Those PFAS figures sit under New Jersey's limits of 14 and 13 ppt. They are above the 4.0 ppt federal standard EPA finalized in April 2024, which systems do not have to meet until 2029 (EPA proposed in May 2026 to allow eligible systems to seek more time, to 2031; that proposal is not final).
None of this means Edison water is unsafe. It means a family deciding about filtration has real numbers to work from instead of a sales pitch.
Why the supplier changes the filter choice
A whole-house filter sits where the main line enters the home, so every tap and shower gets treated water. The most common reason Edison owners want one is the taste and smell of disinfectant. Here is where the three suppliers matter: New Jersey American Water's Raritan System treats its surface water with chloramines, while Middlesex Water reports its distribution residual as chlorine or chloramines. Ordinary carbon handles free chlorine well but is slow against chloramine. Catalytic carbon, and enough of it for the flow your house draws, is usually what a specialist sizes for when chloramine is in the mix.
Other parts of the decision are the same everywhere: a sediment stage ahead of the carbon to protect it, a tank or cartridge sized for the number of bathrooms in use at once, and certification to NSF/ANSI 42 for taste and chlorine, or NSF/ANSI 53 for health-related claims like lead or PFAS. If PFAS is the main worry, point-of-use reverse osmosis at the kitchen sink is often the more direct answer for drinking water.
What a consultation looks like in Edison
You fill in the short form with your ZIP and what bothers you about the water. An independent water treatment specialist who works in the area reaches out, asks who your supplier is, and looks at your report and, where it helps, your water at the tap. You get a recommendation, which can be "you do not need anything" if the numbers say so.
If you go ahead, the installation itself is plumbing work under New Jersey rules (N.J.A.C. 13:32), and the installer who does it must be properly licensed for it in NJ. Central Jersey Water does not install equipment; we connect you with the person who does.

Questions
Does Edison Water Utility treat its own water?
No. According to its 2025 report, it purchases treated surface water from New Jersey American Water's Raritan System and Middlesex Water Company, then distributes it to township customers.
Is a whole-house filter worth it if my water already passes every standard?
It depends on what you want fixed. Passing standards and tasting good are different things. Many people buy whole-house carbon for disinfectant taste and smell in the shower, not for safety. A consultation helps you separate comfort upgrades from problems that need treatment.
Do I need a softener in Edison?
Possibly, but it is a separate question from filtration. Middlesex Water's latest report lists system hardness averaging 157 ppm. A softener removes hardness; carbon does not. Measure at your tap before buying either.
