Depending on the location of the water catchment body, a differentiation is made between

• Vertical drilled wells
• Horizontal wells
• Diagonal wells

Whereby all other versions are only limited to vertical drilled wells.

• Drinking water wells or process water extraction wells which must transport water of sufficient quality over a long period of operation
• Injection or absorbing wells which must allow the introduced water to seep away safely
• Groundwater drawdown wells which are usually supposed to generate short-term large drawdowns with the lowest possible amount of water. The vacuum well, which is used in hard to drain soils, is a pioneering special form in this direction
• Irrigation wells
• Groundwater measuring points (water level), which are supposed to enable the measurement of changes in the groundwater level
• Quality measuring points, which are mainly supposed to enable the withdrawal of water samples for analytical procedures, require a particularly thorough selection of suitable lining material.
