Drinking Water Reservoir in Stegen
Hydrology
Construction of a new drinking water reservoir with two watertight concrete tanks, totaling 350 m³. This reservoir replaced the old one, which no longer met current standards and had insufficient storage capacity. The reservoir supplies the village of Stegen via a pressure system (hydrophore). It is a semi-buried reinforced concrete reservoir with mineral coating on the walls. Stainless steel piping and the hydrophore are installed in the valve chamber to ensure adequate pressure. The reservoir is connected to the municipality’s remote monitoring system for 24/7 surveillance.
