High Water Bills - Causes & Solutions

Your water bills are determined by Saukville Utility staff reading your water meter. When your water bill becomes higher than normal, there is usually a leak in your home.

When your water bill is high, check your toilets - 95% of all leaks are toilets and most times you cannot hear the leak. The toilet most likely leaking is the toilet rarely used. The leaking is often the result a deteriorated flush valve (flapper in the bottom of the supply tank). You can identify this problem by placing several drops of food coloring in the tank - do not flush. if you see color in the bowl after 15 - 20 minutes, the "flush valve" is leaky. The toilet will also waste water when the supply tank water level is set too high, resulting in continuous water waste through the overflow tube. The water level should be about 3/4 inches below the top of the overflow tube. A typical toilet leak at 1/4 gallon per minute will waste over 10,800 gallons each month. This wasted volume will more than double the average water/sewer bill. At current rates, it could add up to $310 to a quarterly residential bill. Therefore, correction of leaks can be well worth the cost of repair and will contribute to the cause of water conservation.

You should also periodically check all of your valves in your home and start reading your meter weekly. This way you can make sure there are no leaks in your home so that you are only billed for the water you use.
