How does the District calculate Bills?
The District calculates the bills by multiplying the water consumption received from the water departments with our current billing rates. Accounts that are on wells do not have a meter to read, so they are billed an average consumption. The District calculates Industrial/Commercial User Fee bills using the flow volume and a concentration value for BOD, TSS and NH4-N (Wastewater Characteristics or WWCs). These WWCs are obtained by sampling and analyses conducted by the Rock River Water Reclamation District. In order to calculate an estimated Industrial/Commercial User Fee bill click here.
