MWUA Water Calculators

We’ve worked with water operators, systems, and regulators across Maine to develop a series of water-focused calculators for industry professionals to use whether in the field, office, or anywhere in between. Please find 10 calculators below developed based on the needs and requests from folks just like you!

Keep an eye on this page as we’ll be working to keep it up-to-date and add more calculators over time. Another 10 calculators will be added by the end of 2022 with even more after that.

Questions about one the calculators or ideas for future tools, reach out to MWUA today. Don’t forget to bookmark this page!

A big thanks to the Maine DWP!

This project would not have been possible without generous financial support, input and review, as well as guidance from the Maine Drinking Water Program and its staff. We’d also like to take the time to thank our many industry experts, contributors, and beta-testers. If you find these tools useful, please take a moment to say thanks as we’re sure they’d love to hear from you.
