Well construction technology
Wells are built today in the most varying versions for a wide variety of applications.
The choice of the right well construction materials fundamentally determines the quality and longevity of a well.
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.
