Where Your Water Comes From

70% of your water supply comes from underground wells located throughout the county, while the remaining 30% is surface water drawn from the Lake DeForest and Letchworth reservoirs. Before it reaches the tap, the water is treated to meet safe drinking water standards.

About the Treatment Process

We treat surface water at our Haworth Water Treatment Plant. The process begins when we pump the water from the Oradell Reservoir into the plant. Then safe drinking water chemicals called coagulants are added to the water. This helps microscopic or suspended particles bind together to form larger particles that are easier to remove from water. Next the water is treated with ozone — a form of oxygen — to destroy bacteria, viruses and parasites. The ozone-treated water then flows to a state-of-the-art dissolved air flotation compartment. Here skimmers remove particles brought to the surface. After skimming, the water flows into a detention basin where large particles settle out. The water then enters a filtering chamber where it flows through layers of coal, sand and gravel to remove the smallest remaining particles. Next, we treat the water with a small amount of chlorine and ammonia to be sure that the water remains pure and safe as it travels to your home. Finally, we add corrosion control chemicals. This step helps prevent corrosion of water mains and household plumbing. It also reduces the chance of lead dissolving in the water from your plumbing.
