WSSC Water’s Industrial Discharge Control Section administers the Waste Hauler Program to manage proper disposal of septage and grease interceptor wastewater at its designated three waste disposal sites. The program also supports compliance by food service establishments (FSEs) by verifying waste servicing documentation, in coordination with WSSC Water’s Fats, Oil and Grease program.
WSSC Water requires waste haulers to obtain either a Waste Hauler Discharge Permit or a Waste Hauler Zero Discharge Permit to operate within the WSSC Water Sanitary District.
A WSSC Water Waste Hauler Discharge Permit is required for each waste hauler vehicle used to dispose of domestic septage and grease interceptor wastewater from FSEs at WSSC Water waste disposal sites. WSSC Water accepts only domestic and greasy wastewater generated within the combined service area of DC Water and the WSSC Water Sanitary District, which includes Montgomery County (MD), Prince George’s County (MD), Arlington County (VA), Fairfax County (VA), Loudoun County (VA), and the District of Columbia.
A WSSC Water Waste Hauler Zero Discharge Permit is required for each waste hauler vehicle that services FSEs within the WSSC Water Sanitary District but disposes of wastewater at facilities outside the district. Vehicles permitted under this category are prohibited from discharging at WSSC Water disposal sites, and the transfer of waste between vehicles for disposal at a WSSC Water site is not permitted. The WSSC Water Sanitary District includes the entirety of Montgomery and Prince George’s counties, excluding certain incorporated municipalities and federal properties as defined in Chapter 805 of the Acts of the Maryland General Assembly of 1981.

WSSC Water operates three designated disposal sites where permitted waste haulers may discharge septage and grease interceptor wastewater into the sanitary sewer system. All sites are monitored by video surveillance, and vehicles must have a valid WSSC Water Waste Hauler Discharge Permit to use the facilities.
