The new Biological Nutrient Removal (BNR) facility is part of a $136 million upgrade of Watercare’s Mangere wastewater treatment plant. The BNR facility uses the same technology currently employed at the Mangere plant to remove nitrogen and phosphorus from the wastewater stream. Common sources of these nutrients include farm run-off, industrial discharges, storm water run-off, and human and animal waste.
Monkey Toe was able to provide 3384m of their modular handrail system with a top rail, mid rail and kick rail to provide safe access over the crisscrossed concrete water tanks of the clarifiers and BNR system. The no-weld system comes to site flat packed and was easily installed by the McConnell Dowell and HEB Construction teams. Monkey Toe have done similar projects before including the Waimate West upgrade in Taranaki.
