Surgeflow 300

surge-flow flow with nature dosing siphon

The Surge-flow Dosing Siphon is installed in a pumpwell following primary or secondary treatment of wastewater and delivers a predetermined flush of water to the Land Application Area.

This reduces the risk of classic trench failure by evenly distributing treated effluent along the entire length of trenches and ETA beds. Treatment efficiency is also improved by wetting and drying of the soil.
