What is a Rain Garden?

 A rain garden is graded slightly to collect several inches of water during a storm, providing time for it to infiltrate into the ground or be used by the native plants- two natural ways of filtering out pollutants!

In the fall of 2017, we installed 7,000 native plants into a constructed rain garden at Bucher Park in Lower Salford Township. Prior to the planting, PWC worked with the township to design and construct the garden, turning a traditional stormwater basin into a beautiful garden. With help from employees from Oehlert Brothers and Key Bank as well as general volunteers we were able to shape the garden and install the native plants. This project was funded through our 2017 MS4 grant program, in which Lower Salford Township submitted the winning application.

Schwenksville Rain Garden

In the Spring of 2017, we installed 3,000 native plants at an existing rain garden in Schwenksville.  Prior to the planting, the garden had become overgrown and contained several invasive species.  With help from career study students from Perkiomen Valley High School, we weeded the rain garden, added some rip-rap along the bottom and planted native species grown in our greenhouse.

We currently have three rain gardens on our property, which capture rain water from our parking lot and driveway.  When we have dry weather, our plants are watered with rain water sustainably harvested from our roof with a 55-gallon rain barrel and a 550-gallon cistern.

The Conservancy is taking new steps toward stormwater management on our own property.  We invite you to visit the installations and read our informative signs, especially if you are looking for ideas to manage stormwater on your own property.

Souderton High School's SAVE Campus

In fall of 2012, students from Souderton High School's SAVE Club (Students Against Violating the Earth) helped install two rain gardens at the club's Environmental Campus next to West Broad Street Elementary School.  The gardens were a prize for Souderton High School students winning first place in the Conservancy's stormwater video contest, sponsored by Verizon.


St. Stanislaus School

The Conservancy installed a rain garden as part of the Lansdale school's outdoor learning classroom.  Many volunteers from the school came out to plant the garden, which is a resource for outdoor learning and experimentation and demonstrates sustainable urban design.
