800-550 - Pump Stations Odor Control Improvements Project

The project consists of civil, mechanical, electrical, instrumentation, corrosion, and structural improvements to the Newark Pump Station and Irvington Pump Station. This includes, but is not limited to, the following:

Newark Pump Station:

• • Replacement of the existing vapor phase odor control system and roof-mounted exhaust fan with a new carbon adsorption system serving pump station odor sources along with exhaust fan with variable frequency drive (VFD), ducting, and demister unit.
  • Installation of new overhead foul air duct support bridge for conveying foul air from the pump station wet well to the new odor control system to the west.
  • Installation of a new stair tower for accessing the pump station roof and providing guard railing at the existing roof parapet.
  • Rebalance supply air and exhaust air flow rates for the existing pump station facility.
  • Repair cathodic protection underground  pipe joint at the pump station surge tower.
  • Miscellaneous civil, structural, electrical, and instrumentation improvements.

• • Replacement of the existing odor control chemical packed tower scrubber system with a new carbon adsorption system serving pump station odor sources along with exhaust fan with VFD, ducting, and demister unit.
  • Installation of temporary odor control system for use during demolition of existing odor control system and installation of new permanent odor control system.
  • Installation of temporary bulk chemical feed system and accessories located in existing concrete equipment pit.
  • Demolition of piping and components located in existing concrete equipment pit currently housing the odor control system and chemical dosing metering pumps.
  • Recoating the interior of existing concrete equipment pit.
  • Installation of new sump pump and associated piping within the existing concrete equipment pit.
  • Replacement of the chemical dosing piping with new double containment piping with leak detection placed in a new utility trench routed from chemical bulk storage containment area to existing valve vault.
  • Expansion, rehabilitation and recoating of existing chemical bulk storage containment area.
  • Relocation of two existing chemical metering pumps to the chemical bulk storage containment area and installation of new VFDs.
  • Demolition of the existing chemical dosing piping in existing valve vault.
  • Concrete repairs and rehabilitation of corroded components in the existing valve vault.
  • Rebalance supply air and exhaust air flow rates from the existing pump station facility.
  • Miscellaneous civil, structural, electrical, and instrumentation improvements.
