How is a Permit Obtained? How much does the Discharge Permit Cost?

It is the business owner’s responsibility and obligation to obtain a permit from Carmel Area Wastewater District. The business owner can request a Permit by:

  1. Completing the application online or downloading it and completing it on your own.  Please see the links on the side of this page for access to both of these ways. 
  2. Visiting the Carmel Area Wastewater District Office located at 3945 Rio Road in Carmel, CA 93922.



Permitted businesses are routinely inspected to see if there have been any operational changes and to determine compliance with permit conditions. A typical inspection includes viewing grease trap or grease interceptor equipment, pretreatment systems, chemicals used, and reviewing documentation such as waste manifests, pretreatment operation and maintenance logs.



Permit violations may be identified during inspections or by reviewing monitoring data. Enforcement actions may include issuing a Notice of Violation, fines or requiring the installation of pretreatment equipment.
