Every pump has a minimum NPSH requirement to ensure continuous flow, which depends on its operating duty point – so the net positive suction head available (NPSHa) needs to be compared to the net positive suction head required (NPSHr) to select a dewatering pump.

Why is dewatering necessary?
It Prepares Soil for Construction Fortunately, the dewatering process ensures the soil is dry prior to excavation. Pumping removes excess water on the ground's surface and underground, which will help firm up the soil. If done properly, dewatering prevents soil erosion and upheaval failure.

Normally the dewatering process is done by pumping or evaporation. It is usually done before excavation for footings and will help to lower the water table that might cause problems during excavations. Dewatering can also refer to the process of removing water from the soil by wet classification.
Methane gas alone is not toxic and does not cause health problems in drinking water but at elevated concentrations it can escape quickly from water causing an explosive hazard in poorly ventilated or confined areas. Escaping gas may seep into confined areas of your home, where it may reach dangerous concentrations.
Aeration is the process of mixing air into water and venting the gas to the outside atmosphere. Aeration can remove methane, as well as other gasses such as hydrogen sulfide (rotten egg smell). Treatment devices range from the simple to the complex.
