Horizontal Wells | Civil Engineering Projects

In our previous series of articles regarding Well Systems and Well Points, we have covered the following:

Now we will move on with our discussion on "Horizontal Wells".

Horizontal wells of about 5cm to 8cm diameter have been used for drainage of hill sides. These wells are drilled into the hill at a slightly upward slope. A perforated casing is installed in the well to collect and discharge water.
Horizontal wells have been successfully installed for horizontal length of 60m.

Large horizontal tunnels have also been successfully used to tap deep aquifers beneath hill sides.

A combined system of vertical wells and horizontal wells can be used to drain stratified soil deposits. In this system, the vertical wells intercept the aquifer and discharge the water into the horizontal well. The water collected by the horizontal well is discharged at a suitable point.
