Rain Guardian Foxhole reduces combined sewer overflows and maintains a safe walkway in Lancaster, PA
Ferguson Waterworks teams up with Jacobs®, an engineering company in Philadelphia, PA, to improve a critical bioretention system at the intersection of Prince and Walnut streets in Lancaster. The Rain Guardian Foxhole was installed to reduce combined sewer overflows (CSOs) and safely convey runoff across the sidewalk.

Why was the Rain Guardian Foxhole recommended as the best pretreatment BMP for the Lancaster, PA, bioretention system?
Pretreatment provided by the Rain Guardian Foxhole elongates the functional design life of downstream bioretention systems and minimizes maintenance intervals. It also maintains aesthetics, which was important at this busy, highly visible intersection.
What are the key features of the Rain Guardian Foxhole?
The RainGuardian Foxhole offers a high-strength, 52lb composite lid that easily supports pedestrian and bike passage. In addition, the modular pretreatment BMP installation is straightforward. Using 3’ easy-to-connect units, contractors fit the Foxhole to the sidewalk’s width, avoiding nearby utilities and maintaining pedestrian access to the sidewalk.
The Rain Guardian Foxhole was installed because it:
- Maximizes system capacity and extends the life of the bioretention system.
- Reduces maintenance requirements and difficulties. Maintenance crews can visually inspect the Foxhole and clean it out using a shovel, broom, and/or hose.
- Eliminates bypass and sediment build-up while protecting nearby vegetation and maintaining a safe pedestrian pathway across Prince Street.
Were Lancaster, PA, and its residents satisfied with the pretreatment BMP?
Yes! The new BMP provided an attractive green space in addition to protecting the city’s water quality. Furthermore, PennDOT, which partially funded the project, is pleased with the outcome.
