Gore Industrial Hub

The project was initiated by the Gore District Council (GDC) as a result of the Mataura Valley Milk (MVM) infant formula processing plant being constructed at McNab, just to the north of the Gore township.  The plant is designed and built specifically to treat discharge from the MVM plant and comprises a stand-alone industrial wastewater treatment plant and a sludge dewatering facility.  The project was funded jointly by GDC and MVM.

Primary treatment of wastewater occurs at the MVM plant including dissolved aeration flotation, flow balancing and pH correction.  Effluent is then pumped through a 7km long underground pipeline to the IWWTP site. The new IWWTP then undertakes the secondary wastewater treatment with treated effluent discharged to nearby existing oxidation ponds.

The plant consists of a 27m diameter concrete and steel treatment tank for anoxic and aerobic treatment and a clarifier, large scale mechanical and instrumentation systems, various ancillary buildings and associated civil works.

Signal was engaged by GDC as project managers for the project following completion of developed design.  Signal led the completion of the detailed design documentation, procurement, construction, commissioning and handover of the project to the GDC.
