    This was an existing community being serviced by conventional septic tanks. High tidal water tables meant that cumulative effect on ground water was significant. The size of sections, flat topography along with the high water table ruled out both “on-site” and conventional gravity reticulation of sewage. Therefore a pressurised sewerage system was a very successful option.

    Small bore high density PE mains were directionally drilled in community berms to receive sewage from Hydro-grind sewage pumps housed in FlowKing™ Polyethylene pump stations. This was a very successful and unobtrusive solution to a serious community problem. It was:
    • cost effective
    • reliable
    • site specific
    • simple to install and maintain.



  • 170 secondary on-site effluent management systems
  • 220 low pressure effluent distribution (LPED or LPP) domestic systems (utilising “powerless” FlowKing™ dosing siphons or pumps).
  • Numerous conventional septic tank systems

  • Powerless effluent management system for the Hokotehi Moriori Trust Marae complex, Chatham Islands, New Zealand. The only power in the Chatham Islands is diesel generated and expensive. The powerless FlowKing™ option was an outstandingly successful option for this project

  • Supply of FlowKing™ dosing siphons to Watchtower, Auckland for Philippines project.
