Pressurized Dewatering: The Economical Solution For Wastewater Disposal Problems

Pressurized dewatering is a very effective solution for removing wastewater in difficult terrain where it is difficult to lay gravity pipes. The pressurized dewatering method of sewage removal has proved very popular in many European countries. 100% of domestic dwellings in Holland, a good example of very flat terrain, have been connected to a central sewage system, and the vast majority is connected via pressurized lines.

Pressure or grinder pump systems utilize a small grinder pump station at each wastewater or sewage source. Small-diameter low pressure sewer lines are used for the transmission of the sewage. This is either pumped to a terminal pumping station or directly to a wastewater treatment plant. Wastewater from the residence or business is collected in small underground grinder pump stations. Stations serving single residential units typically utilize plastic sumps of some 700 mm to 1.2 m in diameter.
