Wastewater Plant

The wastewater plant was built in 2009 and treats over 200,000 gallons per day. There are 5 lift Stations that transfer wastewater from the lift stations to the wastewater plant. Save the Village maintenance costs by not flushing or disposing of the following items down the drains:

  • Razor blades
  • Diapers (disposable and non-disposable)
  • Grease
  • Plastic gloves
  • Dental floss
  • Wipes
  • Tampons/feminine napkins
  • Dye bottles
  • Plastic bags
  • Clothing


These products plug lines and pumps that can interrupt service and cost thousands of dollars in time, repair and chemicals to remove these products from our wastewater system.

Read Your Water Meter

Use your water meter to check for leaks. Start by turning off all faucets and water-using appliances and make sure no one uses water during the testing period. Take a reading on your water meter, wait for about 30 minutes, and then take a second reading. If the dial has moved, you have a leak.


Are you ready to chase down leaks? Household leaks can waste nearly 1 trillion gallons of water annually nationwide.

The average household’s leaks can account for nearly 10,000 gallons of water wasted every year and ten percent of homes have leaks that waste 90 gallons or more per day. Common types of leaks found in the home are worn toilet flappers, dripping faucets, and other leaking valves. These types of leaks are often easy to fix, requiring only a few tools and hardware that can pay for themselves in water savings. Fixing easily corrected household water leaks can save homeowners about 10 percent on their water bills.  Studies show that dripping faucets and leaking toilets account for as much as 14% of all indoor water use, equivalent to 10 gallons (38 liters) per person of water lost per day.

To check for leaks in your home, you first need to determine whether you’re wasting water and then identify the source of the leak.

Here are some tips for finding leaks:

  • Take a look at your water usage during a colder month, such as January or February. If a family of four exceeds 12,000 gallons per month, there are serious leaks.
  • Check your water meter before and after a two-hour period when no water is being used. If the meter changes at all, you probably have a leak.
  • Identify toilet leaks by placing a drop of food coloring in the toilet tank. If any color shows up in the bowl after 10 minutes, you have a leak. (Be sure to flush immediately after the experiment to avoid staining the tank.)
  • Examine faucet gaskets and pipe fittings for any water on the outside of the pipe to check for surface leaks. Check the sink and bathtub faucets, replacing the rubber O-ring or washer inside the valve can usually repair dripping faucets.

Small Changes Can Save $ and the Environment

Save Indoors

In the bathroom-where over half of all water use inside a home takes place:

  • The most common source of leaks is the toilet. Check toilets for leaks by placing a few drops of food coloring in the tank. If after 15 minutes the dye shows up in the bowl, the toilet has a leak. Leaky toilets can usually be repaired inexpensively by replacing the flapper.
    • Toilets can account for almost 30% of all indoor water use, more than any other fixture or appliance.
    • Older toilets (installed prior to 1994) use 3.5 to 7 gallons (13 to 27 liters) of water per flush and as much as 20 gallons (76 liters) per person per day.
    • Replacing an old toilet with a new model can save the typical household 7900 to 21,700 gallons (29,902 to 82,135 liters) of water per year. An average of 20% of toilets leak.
  • Turn off the tap while shaving or brushing teeth.
  • Showers use less water than baths, as long as you keep an eye on how long you’ve been lathering

In the kitchen—whip up a batch of big water savings:

  • Plug up the sink or use a wash basin if washing dishes by hand.
  • Use a dishwasher—and when you do, make sure it’s fully loaded!
  • Scrape your plate instead of rinsing it before loading it into the dishwasher.
  • Keep a pitcher of drinking water in the refrigerator instead of letting the faucet run until the water is cool.
  • Thaw in the refrigerator overnight rather than using a running tap of hot water.
  • Add food wastes to your compost pile instead of using the garbage disposal.

In the Laundry Room-where you can be clean AND Green:

  • Wash only full loads of laundry or use the appropriate water level or load size selection on the washing machine.
  • To save money on your energy bills, set your washing machine to use cold water rather than hot or warm water.
