On a construction site, this dewatering may be implemented before subsurface excavation for foundations, shoring, or cellar space to lower the water table. This frequently involves the use of submersible "dewatering" pumps, centrifugal ("trash") pumps, eductors, or application of vacuum to well points. The international business research ...
The National Register is a federal register for buildings, structures, and sites of historic significance. This is intended to be a complete list of the properties and districts in Columbus. There are 360 properties and districts listed on the National Register in Franklin County , including 3 National Historic Landmarks .
Where no dewatering techniques were effective the mine had to be shut down due to flooding. [3] In the 15th century mine dewatering techniques made some technical advancements as the first mechanized wooden pumps were used in the German Rammelsberg mine (Lower Saxony), and later in the Ehrenfriedersdorf (Saxony) mines in the 16th century.

The Dominion Land Company Site, also known as the Fort Reserve earthwork, was an Early Adena culture earthwork located in the Clintonville neighborhood in the city of Columbus, Ohio. It was excavated by archaeologists from the Ohio Historical Society shortly before being demolished by the Dominion Land Company in 1953 to make way for a housing ...
The Ridgeway Site (also known as the "Ridgeway Kame" or the "Richardson Kame") is a former archaeological site and burial site in the west-central part of the U.S. state of Ohio.

This is a list of Superfund sites in Ohio designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law.The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

Exhausted open pit mines may be refilled with tailings. In all instances, due consideration must be made to contamination of the underlying water table, among other issues. Dewatering is an important part of pond storage, as the tailings are added to the storage facility the water is removed – usually by draining into decant tower structures.
Air-drying and composting may be attractive to rural communities, while limited land availability may make aerobic digestion and mechanical dewatering preferable for cities, and economies of scale may encourage energy recovery alternatives in metropolitan areas. Sludge is mostly water with some amounts of solid material removed from liquid sewage.
