1. Churchyard Cemetery Mapping

    A church was concerned that its walled cemetery excluded some very old unmarked graves, likely containing wooden caskets, given their age. To resolve this uncertainty, RETTEW conducted a ground penetrating radar (GPR) survey to detect any anomalies that might represent unmarked burials. RETTEW scanned the areas just outside the cemetery boundary walls with a digital…

  2. Asylum Run Sewer Interceptor Replacement

    Penbrook Borough’s existing 12-inch vitrified clay pipe (VCP) gravity sewer line was constructed in the 1930s and conveyed sewage flow from both Penbrook Borough and Susquehanna Township to the Capital Region Water sanitary sewer collection and conveyance system, a National Pollutant Discharge Elimination System (NPDES)-permitted system.

  3. West Hempfield Township Pollutant Reduction Plan

    As an MS4 permittee, West Hempfield Township needed to submit a pollutant reduction plan (PRP) to comply with the Pennsylvania Department of Environmental Protection’s MS4 Program requirements. The Township needed to determine the existing pollutant loading rates attributed to the MS4-regulated area, and identify stormwater best management practices (BMP) to reduce sediment, phosphorus, and nitrogen…

  4. Lefever Road Detention Basin Retrofit

  6. Paradise Township Community Readiness Assessment

    Paradise Township previously created a comprehensive plan that identified initiatives and projects it wanted to undertake.

RETTEW facilitated strategic planning discussions with Township officials, staff, and residents using our community…

The park…

  8. Highspire Borough Stormwater Fee Study

    Small municipalities face tremendous financial burden in managing stormwater and complying with water quality regulations. Enacted and enforced by the U.S. Environmental Protection Agency and the Pennsylvania Department of Environmental Protection, these regulations, while beneficial, caused Highspire Borough to search for alternative funding for maintaining stormwater management facilities. RETTEW began assisting the Borough by presenting…
