In order that the incoming water does not disturb the sediment on tank floor, the water is introduced as slowly as possible from the tank floor upwards.
This is done by the so-called calm intake.
Inlets pipes go to bottom of the tanks.
At end of the inlet pipes, there are provisions for the calming inlet.
The Calming Inlet performs several functions that are imperative to maintaining a high quality of water within rainwater harvesting tank.
The calming inlet acts as a mosquito barrier by creating a water trap between the inlet pipe and the tank, preventing mosquito entry into the tank.
Additionally, the calming inlet helps to introduce oxygen into the cistern water – helping to prevent stagnation – prevent anaerobic decomposition.
Perhaps most importantly, the calming inlet prevents any sediment bed from being disturbed. The calming inlet broadcasts the water up into the tank rather than allowing it to splash down. By keeping the sediment bed intact you help to improve the life of your pump – if any – since it will not be sucking up sediment, provided that a floating extractor is used.
Made of food quality polyethylene, the high quality construction of the calming inlets reduce water costs and the strain on water consumption.
