Johnston Construction Company

• Johnston Construction Company served as Prime Contractor for the General Construction improvements associated with the comprehensive rehabilitation of Greene Township Municipal Authority’s Pump Stations No. 2 and No. 3. The overall project was divided into separate General Construction and Electrical Construction contracts.
• Rehabilitated two active municipal wastewater pump stations, incorporating demolition, wet-well reconstruction, dry-well abandonment, new submersible pumping equipment, process piping, controls, site improvements and restoration.
• Maintained uninterrupted wastewater conveyance through temporary bypass pumping at both pump stations while the permanent facilities were being rehabilitated, including temporary connections to the existing force mains.
• Removed existing wet-well and dry-well top slabs together with obsolete pumps, piping, ladders, platforms and associated equipment to prepare the stations for conversion to modern submersible pumping facilities.
• Abandoned the existing dry wells at both locations and installed reinforced-concrete caps approximately 1.5 feet thick by 10 feet by 10 feet following demolition and placement of approved fill material.
