Welcome to the Wellsville Water Treatment Plant. This plant started treating water for the Village of Wellsville on June 28, 1990. This plant is rated for 2.5 million gallons per day. The average daily consumption is currently at 900,000 gallons. Take the following tour to learn how your water is treated before you use it and hopefully you will not take this precious resource for granted.

We will start this tour from the very begining. Our source of drinking water is the Genesee River.

We take the water from the river at our intake. The water is then pumped to the treatment plant.

When the water enters the plant, we add a coagulant. This chemical causes the smaller particles of dirt to attract to each other forming larger particles that can be filtered out.

This picture shows how the coagulant works. If you look closely you can see what looks like snowflakes in the water. This is called the floc (the small particles attaching to each other)

This view shows how the larger particles start settling out. You can now see that the top portion is begining to clear up.

This final view show how most of the particles have completely settled out. The top portion is clear and you can see how it has settled on the bottom.

We add chlorine (disinfectant) then the water enters the clarifier portion of each filter through the light green lines. We have three filter units in our plant.

The water goes up through the clarifier, where 80 to 90 % of the particles are removed.

We have to clean the clarifiers periodically according to how dirty the river is. This view shows the beginning process of the clarifier cleaning.

This is another view of the clarifier cleaning. You can see how much is removed from the river. This flush water goes to the waste water treatment plant.

The water goes from the clarifier to the top of the filter, where it goes down through the filter for the finishing portion.

This is a cutout view of the filter unit.

This view show the different stages of the filter. From the normal, to clarifier flush to filter wash.

As with the clarifiers, we have to also wash the filter area. This view is of the begining of that process.

Another view of washing the filter, you can start to see the amount of particles that the filter has taken out of the water.

This is a view of the full portion of cleaning the filters. This water also goes to the waste water treatment plant.

After the water is filtered, then it goes to our clearwell where we add, chlorine (disinfectant), soda ash (pH control), fluoride (for your teeth). The water leaves the filter in the light blue lines.

It takes the water approximately four hours from the time it leaves the filters to the time it is pumped out. This allows all of the chemicals to work properly. The above picture shows some of the pumps that pump the water to the reservoir.

As the water leaves the plant it is continously monitored, for chlorine, pH, and turbidity (dirt). The water is continously monitored after each filter also.

This is a view of the influent part of our filter units. You can see the control board in the background.

The water is pumped from the plant to the reservoirs and then it goes to YOU>>>>

When the water is used by YOU, it has to be metered so that we can track our demand. The above picture is of a standard home water meter. These meters are larger for businesses and industries.

The valves on the filters are pneumatic and this is a picture of our two compressors that supply the air to the valves.

This is our maintenance room.

This is our laboratory where we perform different tests, on all aspects of the treatment process, daily.

 

As required by New York State, all of our operators are licensed. We are required to attend refresher classes each year to renew our licenses. Our goal is to provide you with a reliable, safe and adequate supply of water. We take this responsibility very seriously. We will always adhere to all Local, State and Federal requirements.
