Bryn Mawr Sewer Repair/Storm Water Improvements/ Stream Restoration
These young homeowners bought a beautiful house in Bryn Mawr that came with a few surprises. First, the sewer pipe that exists the house crosses through Darby Creek at the rear of the property through a concrete encasement that had settled and shifted, breaking the pipe, resulting in years of sewage contamination of the creek. The settled encasement also altered the course of the stream and caused erosion of the stream banks.
We set up a temporary pump bypass of the stream, exposed the broken pipe, removed tons of contaminated soil, installed a new sewer pipe built into a new concrete encasement, and restored and stabilized the stream banks.
The homeowners also experienced storm water pouring down the driveway in heavy rains, causing water to enter the house over the front door sill. We designed and installed a storm water collection system consisting of 2’x2’ concrete inlet boxes in the driveway, Belgian block curbing along the driveway, and a properly sized main storm water drain pipe with downspout connections to the rear of the property.
