This permit is utilized by DERM to monitor non-residential facilities and enforce the Miami-Dade Sewer Discharge Standards of grease waste discharged to the sanitary sewer when the flow is less than 25,000 gallons per day.

Prior to 1994, Miami-Dade County experienced a number of grease related overflow problems that needed to be resolved. The solution began with the creation of the grease discharge program. Since the program began, the number of grease related problems have decreased and the number of grease interceptors in the county has increased.

No other permit is required.  However, depending on the type of facility, there may be other permits required for construction and/or installation of a pretreatment system.  You must contact DERM Plan Review at 786.315.2800 for additional information prior to construction.

If brought in personally, usually no more than 20 minutes.

Fees are based on actual or calculated water flow. The calculation is derived from the number of seats or the facility area in some cases. Please see DERM Fee Schedule .

Grease Discharge Permits are valid for one or two years depending on the fee amount; all other permits are for one year only.

This permit is NOT required for IW-6 Program facilities, which are facilities on septic systems located within wellfield protection areas.

Yes, all non-residential facilities within municipalities with the exception of City of North Miami require DERM’s GDO permits.
