Chase River Forcemain No. 1 Replacement and
Pump Station Upgrades

The Chase River Pump Station receives wastewater from the south end of the City of Nanaimo. Wastewater from the Pump Station is conveyed approximately 1.1 km northward along Haliburton Street to the Nanaimo Interceptor Pipeline through the twin 450 mm diameter Ductile Iron pipes (Chase River Forcemains No. 1 and 2). The Forcemains were installed in 1980 and 1998 respectively. Several leaks on Forcemain No. 1 were detected in 2017 and the need for a full-scale replacement of the forcemain was identified.

The purpose of this RFP is to select a firm having the experience and expertise needed to work with RDN staff in the provision of detailed design, permitting, and tender support for the replacement of Forcemain No.1 and upgrades to the Chase River Pump Station. The new Forcemain upgrade will generally follow the same alignment and grade of the existing Forcemain No. 1 with the exception of the Chase River crossing.

The design objectives for the forcemain replacement and pump station include:

  • Remove and replace Chase River Forcemain No. 1 with new upgraded High Density Polyethylene (HDPE) or PVC pipe in the same alignment and grade, sized to accommodate future capacity and redundancy for maintenance with Forcemain No. 2 out of service.
  • Re-align the new forcemain along a bridge-mounted crossing over Island Highway across Chase River existing bridge as above grade support.
  • Provisions for improved Pump Station grit and rock removal at the pump station inlet.
  • Expanded forcemain valve chamber with access / egress improvements.
  • Upgrades to the existing septage receiving facility.
