Dewatering is the process of removing water from a construction site and moving it to another place, like a detention pond or forest, to make the construction site safe to work on. Dewatering is a necessary step in preparing an area for construction work.

What are the construction dewatering techniques?

Main dewatering techniques
  • Wellpoints. In Wellpoint, wells are drilled around the excavation area with submersible pumps installed in the well shaft.
  • Deepwells. In Deepwell, one or several individual wells are drilled, and submersible pumps are placed in each shaft.
  • Bypass dewatering.
  • Flood control.
  • Tunneling dewatering.

What is the difference between pumping and dewatering?

Water pumps are designed to move water from one location to another, while dewatering pumps are designed to remove water from an area where it is not wanted, such as from construction sites, mines, or flooded areas.

What are the two principal ways to keep groundwater out of excavations?

Site dewatering is usually achieved by controlling groundwater through exclusion (permanent) or removing it by pumping (temporary or permanent). Groundwater control by exclusion is achieved by constructing an impermeable or low permeability cut-off wall to keep the groundwater out of the excavation.

FAQ

What is the wheel wash system for construction sites?

Wheel washing systems can be installed on construction sites to enable the wheels of plant, trucks and other vehicles to be cleaned before leaving the site. This is used to control and eliminate mud, slurry and other pollutants being deposited on public roads.

How do you manage concrete washout?
Keep washout area at least 50 feet from streets, storm drains, open ditches and streams. Contain the disposal to keep concrete from flowing down slope. Use washout area only for chutes, tools and equipment. Install storm drain protection at any inlets that are down grade from the washout.

What is a concrete washout structure?

Concrete washout is a designed structure in a designated area of a construction site, where all slurry concrete is washed and removed from construction equipment. Concrete washout prevents slurry concrete from leaving construction sites, thus preventing stormwater pollution.

How does construction affect groundwater?

Proper drainage is a crucial consideration in land development. Groundwater can be blocked from its normal course of flow by new construction and accumulate in the ground. Water close to the underside of the basement floor can rise up through the slab and cause dampness.

What is the problem associated with groundwater?
Groundwater pollution is a serious problem because many people get their drinking water from wells. Agriculture, manufacturing, and underground storage tanks are just a few of the harmful substances that enter the ground and percolate down to aquifers below.

What are the most common construction site pollutants in water?
Suspended Solids (Silty Water)

The most common source of pollution on construction sites is suspended solids (silt-laden waters). This is primarily due to the ease in which it can occur.

What are the negative effects of underground water?

A control valve is used for controlling the flow of water. Sluice gate is a gate that controls sluice which helps in controlling the flow of water.

What is the proceedure for watter being pumped in road construction

How do you stop water flow to build a dam? Streams and rivers have to be diverted to create a dry area to construct the dam. Small rivers and streams are usually diverted through a tunnel, or a channel that is constructed around the side of the dam.

How do dams reduce river flow?

Dams slow rivers

Dams can also alter the timing of flows. Some hydropower dams, for example, withhold and then release water to generate power for peak demand periods. These irregular releases destroy natural seasonal flow variations that trigger natural growth and reproduction cycles in many species.

What is a dam constructed to control the flow of?

Dams are mainly built to control the flow of rivers. They usually hold the water back. If the flow of rivers are not controlled, it will result in the overflow of water. This can cause a severe impact on people, animals and plants inhabiting in that area.

What controls river flow?

There are several factors that affect the discharge of rivers at any given time. These factors include the size of the drainage area (or watershed), climate, land use/land cover, soil type, and the topography of the watershed.
