This Place Is BMPing: Saylors Grove

Each week, we profile a BMP—short for Best Management Practices—to demonstrate how local businesses, organizations and neighbors are helping to keep our streams and rivers clean by managing stormwater on their property.

Saylors Grove after the creation of a stormwater wetland

Before the Philadelphia Water Department constructed a stormwater wetland at Saylors Grove in Fairmount Park, the area received an excessive amount of runoff that drained into Monoshone Creek, a tributary to the Wissahickon, resulting in erosion of the Monoshone and impaired water quality. The creation of a one-acre wetland in 2006 now handles approximately 25 million gallons of urban stormwater each year, slowing the flow to the Monoshone and filtering the stormwater naturally by removing pollutants as the water cascades over rocks en route to the wetland.

PWD continues to monitor this stormwater wetland to determine the reduction in stormwater flow to the creek and analyze its performance. It is estimated that the wetland intercepts 73% of the watershed's annual runoff.
