E2PM was retained by a commercial restaurant owner to assist with a septic disposal system replacement for former RosaLuca Italian Bistro restaurant in Bethlehem Township, New Jersey.  The property owner was seeking to replace the existing malfunctioning and non-compliant septic disposal system within the property.  The building was a 75-seat restaurant and a 2-bedroom apartment that was served by an onsite potable well. 

E2PM’s involvement with this project included providing a range of engineering, surveying and construction management services through completion of the septic replacement.  E2PM assisted with the design plans for the new septic disposal system with a design sewage flow of 2,950 gallons per day.  The septic design included use of advanced treatment devices and timed-discharges to adequately treat the restaurants high-strength waste stream prior to discharge to a new septic disposal field. Due to the presence of wetlands within proximity to the project area,  E2PM was also responsible for preparation and submittal of state applications prior to any construction activities. 

Overall tasks included:

  • Completing a partial topographic survey
  • Conducting a Soil Investigation and Site Study, including coordinating backhoe operations and evaluating environmental constraints.
  • Performing soil testing and collecting well and septic system location data from neighboring properties and evaluating available site constraints. Perform one day of soil testing. 
  • Preparing Septic Disposal System Design and Soil Erosion and Sediment Control Plan and submitting to Township Health Department and Hunterdon County Soil Conservation District for review.
  • Preparing NJDEP application for a T-1 General New Jersey Pollutant Discharge Elimination System (NJPDES) applications.
  • Preparing Treatment Works Approval permit applications for the NJDEP.
  • Preparing a Freshwater Wetlands General Permit #24 for wetland and buffer disturbances related to septic system installation.
  • Performing survey stake locations of septic system components for construction.
  • Performing periodic site inspections during construction of septic disposal system between 2020 and 2021.
  • Preparing As-built drawings and assembling paperwork for submittal to Hunterdon County Health Department.
