Business Sewer Capacity Charges

The charge will be calculated based on the business's actual or estimated flow and strength. A rate formula is used to convert the total cost of treatment for the business's wastewater to equivalent dwelling units. Please refer to the Capacity Charge Calculation PDF.

Industrial users must call for an appointment with our Customer Service Department for a plan check review.

Please bring the following with you:

  1. Copies of water bills or submeter readings for the preceding one-year period or a reliable estimate of water usage for the industry, and measured or reliable estimates of wastewater effluent strength such as biological oxygen demand (BOD) and suspended solids. Acceptance of the reliability of the estimates will be at the discretion of the Monterey Regional Water Pollution Control Agency.
  2. A copy of the final building plans required for issuance of your building permit.
  3. Check, cash or money order.

Applicants are also required to confer with M1W's Source Control Department to determine whether an industrial wastewater discharge permit will be required. Please contact them at (831) 883-1118 or (831) 424-1108, preferably prior to applying for the sewer capacity permit.

A M1W Field Inspector will inspect the site after the project is completed and will monitor the business category type annually. Additional charges will be required if categories change from the original application.
