Winner - Best Tasting Water in Wisconsin, 2013 WWA State Fair competition

Project H20

Madison Water Utility is nearly finished upgrading all customer water meters to a wireless technology network that reads and transmits water consumption on a daily basis. So far, more than 63,400 new metering systems have been installed in homes and businesses across Madison.

There is no charge for installation or for the new metering system.

Benefits of the new metering system:

  • Customers will be able to track their own daily consumption online by October of 2014.
  • Will allow us to transition to monthly billing in mid-2014.
  • Allows us to spot costly residential water leaks and alert customers - hundreds have been alerted so far.
  • Eliminates the need for a water meter reader to visit your premises.
  • Provides an energy efficient, accurate, and cost effective way for MWU to read water meters.
  • Helps the utility operate our entire system more efficiently with accurate consumption data.

To schedule an installation call our meter shop at (608) 266-4765 or send an email. In your email, please include your name, address, and phone number.

Installations will be by appointment. In most cases, installations should take no longer than 30 minutes and will not interrupt your water service. An adult resident at least 18 years old must be present.

Employees and contractors involved with the project will be identified by photo IDs, and will arrive in Madison Water Utility work vehicles.

Note: Even if you choose to pay a monthly fee and opt out of the wireless Project H2O technology, you will still need to schedule an appointment to convert your meter to read gallons instead of cubic feet (ccf).

Project H2O is already saving customers water and money through improved leak detection. See NBC 15's story which aired on April 1, 2013 for details: Smart Water Meters Spot Leaks in Madison.

The new system uses radio frequencies (RF) to transmit meter readings. While we believe the use of this technology is extremely safe, some customers may choose not to have a transmitter inside their home. MWU's opt-out policy offers two options: have the transmitter installed on the outside of the building, or not have it installed on the property at all.
