The well water is extracted straight from the ground water with a well pump and then fed into the service water piping. Modern pump controls are used to steer the pumps energy efficient by regulating the output and switching the pumps on and off depending on demand.

The principle of operation is safe and easy: The pump is turned on automatically once an appliance consumes water. As soon as the appliance stops consuming water, the pump is turned off. Additionally, the pump controls usually dispose of a protection against dry operation so that the pump is turned off if not enough water is available.

Modern pump controls regulate the well pumps in a way that they pump water with a constant pressure. By changing the pump’s motor speed it is made sure it produces only the necessary performance. The controls thereby also contribute to saving energy and reducing the pump’s wear and tear.
The well pumps can be installed quickly and easily and are frost-resisting inside the well. And since they are installed under water annoying noises from operation are reduced.

Because ground water can be available in different qualities it might need to be treated before use. In order to find out if such a treatment is necessary a water quality inspection needs to be conducted. The findings can help focusing on the substances that need to be filtered out.

Oftentimes it is totally sufficient to simply filter out sand particles and smaller substances. It might, however, be required to remove substances like iron or manganese from the water so that the service water does not have sustained discolorations.
