Submeter Program

Examples of business processes where water in
does not equal water out

Water flowing to sewer is less than water in:

  • Cooling towers or boilers are used
  • Landscape irrigation
  • Beverage bottling, food production and packaging

Water flowing to sewer is more than water in:

  • Uses water from a well
  • Rainfall harvesting
  • Bringing in hauled water for discharge to the sewer

The Submeter Program is for business customers who discharge a volume of water to the sewer significantly more or less than the incoming water which helps support the City's equity goals. To be eligible, your business must:

  • Be a City of Portland sewer/stormwater/water utility customer.
  • Pay the commercial rate for sewer and water charges.
  • Put water into a manufactured product, operate cooling towers, or other systems that evaporate water or irrigate a landscape.
  • Determine that the cost of the water volume going into product, evaporation, and/or irrigation exceeds the costs and fees for a submeter. Contact the Submeter Program at 503-823-7856 for assistance with these calculations.
  • Be willing to purchase, install, regularly maintain and calibrate a meter for the purposes of measuring water/sewer that may affect sewer billing.
  • Commit to read, record, and submit submeter reads per a schedule established by Environmental Services.

Participation requires meeting Portland City Code (PCC) chapter 17.36.050 and Submeter Program Administrative Rules ENB-4.32. Customers install submeters on their business’ internal plumbing to accurately measure and bill for water that is discharged to the sewer.

Current Administrative Costs

To participate, a business pays program and administrative costs per meter and per bill. The yearly administrative costs depend on how many submeters your business has installed and how frequently your business is billed for sewer, stormwater, and water services—either monthly or quarterly. Fees for the 2021-2022 fiscal year are about $100 per meter per bill. Rates change in July.
