How is sanitary sewer usage determined?
Wastewater fees are billed to all users connected to the Eugene-Springfield Regional Water Pollution Control Facility. Customers pay a combined fee which includes: A basic Metropolitan Wastewater Management Commission (MWMC) monthly charge; and a flow-based fee, calculated on the amount of water used and customer category. Flow fees are determined from water meter readings during the winter months (December through April). May through November bills are based on the average of the winter usage or actual usage, whichever is less.

How can I tell if I have a water leak?
There are several ways to check your plumbing for a leak. The most common leak we see is a silent toilet leak. To check for one, put a few drops of food coloring into the tank of the toilet and wait several minutes. If the color seeps into the bowl, you have a leak.

A good way to check if you have a leak somewhere in your system is to do an overnight meter read. You just write down the reading on your meter before you go to bed for the night (make sure no water gets used over night) Then read the meter again in the morning before you use any water. If the numbers change, you have a leak somewhere. You can also do this when you are going to be out of the house for the day.

Most of the meters in use today have a flow detector on them. This is a small red triangle inside a bubble located under the numbers on the meter. When you are using water, the triangle spins. If you are not running anything that uses water and the triangle is spinning, you probably have a leak.

Why is my sewer bill higher than my water bill?
The cost of sending clean water to a customer is considerably less than cleaning and purifying water discharged into the sanitary sewer system so that it can be returned to the Willamette River. For more information, see our Rates page.
