What is a Submeter and how will it lower my wastewater bill?

Posted 5/26/21: Due to national shortages in meter equipment supplies, the Portland Water District is temporarily unable to issue submeters or deduct meters at this time.  Once supplies are replenished, submeters will be available for purchase again. If you are interested in purchasing a submeter when they become available, please submit the application below (without payment) to PWD. We will contact you when we can fulfill your request.


If you do a lot of outside watering, you could lower your wastewater bill by purchasing a submeter.

A submeter measures water from your outside faucet that doesn’t enter the wastewater system. The amount of water measured by the submeter is not billed municipal wastewater charges.

The submeter program is managed by the Portland Water District on behalf of the municipality (Portland, Windham, Westbrook, Gorham, Cumberland, Cumberland, Cape Elizabeth, South Portland).  Some municipalities require application fees and plumbing inspections.

Customers may return unused submeters if purchased within the last 90 days. Customers will be refunded the purchase price of the submeter minus a $30 restocking fee.
