Percolation Testing and Request for Results
All properties are either served by public sewer service (provided by WSSC) or a private septic system as its means of wastewater disposal. Before a property can be considered 'buidable' by Department of Permitting Services, the property must either be confirmed as servicable by WSSC or satisfactory percolation testing must be completed to establish a sewage disposal area to serve the property.
Please refer to the Percolation Test procedure for more details on the process by which testing is conducted.
Request Percolation Test Results
If you wish to file a request for percolation test results for a specific property located in the County, please submit a completed Request for Percolation Test Results to DPS Well and Septic section.
