Carterton District Council

Project Description: Kaipatangata Water Supply

Reaman Industries designed, supplied and installed a 200m3/hour Multi Layer Filtration/Bag Filter System, including pipework and valves, programmable logic controller and motor control centre including testing and commissioning the system.


This was the first of its type in New Zealand and was designed by Water & Waste Treatment NZ Limited in a joint venture with Reaman Industries to provide not only water of a quality to exceed the drinking water standard of New Zealand, but to ensure the removal of water born protozoa including giardia lamblia and cryptosporidium cysts.


It is considered by leading world authorities on water treatment, that the removal of giardia from drinking water only requires the removal of particles greater than 5 micron and for the removal of cryptosporidium particles 2 micron and greater. However, this system includes a 2-stage filtration process to ensure the removal of 99.9% of all particles 1 micron in size and larger (the naked eye detects particles greater than 80 microns).


As a result of the filtration process, the water leaving the plant will not only be free of parasites but will be close to bottle water quality. The computer-driven plant is close to being fully automatic and requires little operation attention. The free chlorine residual and the pH is automatically maintained and the turbidity of the water is measured both on entry to the plant and after treatment. Flow is continuously measured and totalised.


This system utilises Bruner multi-layered filters with a 10 micron particle retention followed by bag filters with 1 micron absolute retention to ensure the removal of all water born protozoan cysts including giardia and cryptosporidium. Disinfection and pH is fully automated with the latest chlorination and monitoring equipment from Capital Control Co Inc of USA and the plant operation is controlled by Allen Bradley PLC.

Te Aute College, Central Hawke’s Bay

Project Description: Water Treatment Plant

Reaman Industries supplied a 20m3/hr water treatment plant to produce potable water to the School’s spring water supply. The water is filtered to 5 micron and softened through industrial water softeners at the end of this process. The treated water passes through taste and odour treatment processes prior to entering the school’s reticulation system.

Construction: 3 Months



Village of Luggate, near Wanaka

Project Description: Rotating Biological Contactors Waste Water Treatment Plant

In 2003 Reaman Industries supplied and installed a 110m3 waste water treatment plant in the Village of Luggate which is adjacent to the township of Wanaka.  This project was completed to time and budget.


After discussions with the consulting engineer MWH, an S&P subsurface RBC complete with primary treatment tanks, filtration and disinfection processes were supplied and installed.  The treated effluent is discharged to deep bed disposal trenches which are rotated on a regular basis.
