What is a well point?
A wellpoint is a small-diameter, closely-spaced shallow well, which offers a highly economic and versatile method of groundwater control where drawdown requirements onsite are less than 5-6 metres in depth.
What kind of pipe is used for a well?
Poly pipe is fast becoming the most common and efficient way to install a submersible well pump. With most well depths up to 350′ the 160psi HDPE Black Poly Pipe shown below in green is the top choice for well pumps and solar well pumps.
What is a water source well point?
A Well Point is a piece of pipe that has openings large enough to allow water to enter but also small enough to keep the water-bearing formation in place.
How deep can you drive a well point?
Although you may want to drive deeper for adequate water supply, do not try to drive well point greater than 50′. Keep all pipe joints tight to eliminate air leaks and improve pump efficiency.
What’s the difference between a well point and a borehole?
Basically, how Borehole Drilling Companies define the difference is: typically, a borehole is drilled by machine and is relatively small in diameter and a well is usually sunk by hand and is relatively large in diameter.
How deep can a Sandpoint well be?
about 20 feet
Atmospheric pressure of about 14.7 pounds per square inch allows a shallow-well pump to pull water up from a maximum depth of only about 20 feet (Figure 2).
What size is a well pipe?
Use the required diameter of piping that is called for by the pump’s manufacturer. This can range from 1 inch to 2 inches in diameter. A 1-inch schedule 80 pipe is approximately 3/16 of an inch thick and a 2-inch-diameter schedule 80 pipe is almost a full 1/4-inch thick.
How does a well point system work?
A wellpoint system consists essentially of a series of closely spaced small diameter water abstraction points connected, via a manifold, to the suction side of a suitable pump. The wellpoint technique is the pumping system most often used for modest depth excavations, especially for trenching excavations.
Are point driven wells good?
properly located and constructed, and taking into consideration the land use in the immediate area, driven point wells can offer protection from most types of contaminants, especially biological contaminants like bacteria.
Is a Sandpoint well good?
If your soil is high in clay or contains many large rocks, a sand point well may not be the best choice for your home. However, if you’re seeking an inexpensive well installation option and your area’s water table is within about 30 feet of the surface, a sand point well might be a good choice for you.
How does well point work?
A Well Point is a piece of pipe that has openings large enough to allow water to enter but also small enough to keep the water-bearing formation in place. The well point is then drove into the ground, passing the soil and clay until it has reached water bearing gravel and sand.
