The Environmental Services Division (ESD) coordinates several development
review programs under the County’s Water and Sewer Plan. Constituents
seeking waivers for private wells or septic systems, or for connection to
public water and sewer services, must have specific authorization from the
Department of Environmental Resources (DER). In addition, developers seeking
to advance commercial, industrial or residential projects must have the
properly designated water and sewer service category. Changes to these categories
must also be authorized by DER. For more information, call (301) 883-3311.
