Septic Management Program

West Brandywine Township launched a Septic Management Program in January 2018. The Pennsylvania Department of Environmental Protection required the Township to institute this program as a means of protecting our local groundwater and surface water resources. It is an extremely important matter of health and welfare for our community. The program requires scheduled maintenance and inspections to assure proper operation of all on-lot septic disposal systems in West Brandywine Township.


Maintaining Your Septic System...

Protects your property value

An unusable septic system or one in disrepair will lower your property value, and potentially can pose a costly legal liability.

Protects the environment

More than four billion gallons of wastewater are dispersed below the ground’s surface every day. Ground water contaminated by poorly or untreated household wastewater poses dangers to drinking water and to the environment. Malfunctioning septic systems release bacteria, viruses, and chemicals toxic to local waterways. When these pollutants are released into the ground, they eventually enter streams, rivers, lakes, and more, harming local ecosystems by killing native plants, fish, and shellfish.

Keeps you and your neighbors healthy

Household wastewater contains disease causing bacteria and viruses and high levels of nitrogen and phosphorus. If a septic system is well-maintained and working properly, it will remove most of these pollutants. Insufficiently treated sewage from septic systems can cause groundwater contamination, which can spread disease in humans and animals. Improperly treated sewage poses the risk of contaminating nearby surface waters threatening swimmers with various infectious diseases, from eye and ear infections to acute gastrointestinal illness and hepatitis.

Property owners maintain ownership of their individual on-lot disposal system and are responsible or the operation and functioning of their system.  However, this needs to be done within Township guidelines:

The Township requires that individual OLDS be pumped out at least once every three years, as well as proof that this maintenance was performed.

As part of the monitoring process, each owner of an OLDS is responsible for providing proof to the township that their system is being pumped out at least once every 3 years.

Residents can mail pumping verifications to
