Project Details:

This project involved installing over 1300m of a PE sewer pumping line which ranged from 400-450mm in diameter. It is the main pumping line which connects the Ajax Pump Station to the Gore District Councils Waste Water Treatment Plant.

It also consisted of:

  • installing numerous scour and air valves
  • complex link-ins to the Pump Station and the inlet screens at the WWTP
  • installing a 675mm concrete overflow line and 2300x2440mm chamber from the inlet screen to the treatment ponds
  • Crossing the main south Kiwirail line and SH1 without causing any disruption to both networks. We engaged KB Contractors to pipe jack a steel carrier pipe in which we pulled our 450mm pumping line through with our directional drill.
