Archway Group in Te Puke are acknowledged as experts in nutrient containment and control of effluent from dairy sheds and feed pads.
The company works North Island wide building weeping walls, a proven means of passive (non-mechanical) separation of effluent liquids and solids. The solids are held for later disposal and the ‘green’ water collected for yard and feed pad cleaning, or it can be sprayed to pasture on lower rates.
“We have been flat-out installing the weeping walls and Tri-Block bunkers as farmers see their advantages. We’ve recently installed several weeping walls for different Maori trusts in the central North Island,” said Amanda Hodgson a partner with Matt in Archway Group.
The company also offers a free infrastructure plan to help farmers to assess where regulations might take them in longer term.
