2018 Statewide Water and Wastewater Rate Study


The Department of Natural Resources and Conservation (DNRC) has collected rate information from communities for the last 6 years. Information has been requested and compiled in the fall of 2013, 2015, and 2017.

A request for rate information was sent out to communities in the fall of 2017. Communities were provided their previous rate study information that was on file for the community, and were asked to complete the current rate information.  DNRC requested that the information be returned by January of 2018.

The rate study information being provided is raw data. Communities use different methods to charge their rate payers.  Some communities use a flat monthly rate and some communities use a monthly usage rate.  There can be a big difference in how communities pay for their water and wastewater services.

This raw data is to give some ideas on what different communities are charging for their water and wastewater services. The last column in the spreadsheets show the percentage change between 2015 and 2017.

This report explains the methodology used to collect the survey data and presents the results of the study.
