The Groundwater Discharges Section (GWDS) is responsible for overseeing all aspects of the siting, design and installation of onsite wastewater treatment and disposal systems (a/k/a septic systems). The section also issues waste transporter permits and licenses to percolation testers, designers, soil scientists, system contractors, liquid waste haulers and system inspectors.
The Groundwater Discharges Section is broken down into two branches; the Small Systems Branch, which has two offices (one in Dover, serving Kent and New Castle Counties and the other in Georgetown, serving Sussex County) and the Large Systems Branch in Dover (serving all three counties).
The Large Systems Branch reviews and approves spray irrigation wastewater systems, onsite wastewater treatment and disposal systems with daily flows greater than 2,500 gallons per day, Experimental/Alternative Technologies, Advanced Treatment Units, underground injection wells, and other means associated with land application wastewater treatment
