Schaan and Vaduz secure drinking water supply – Liechtenstein
VADUZ/SCHAAN – A massive increase in water consumption is expected in Schaan over the next few years. To meet this challenge, the municipalities of Schaan and Vaduz are renewing a contract from the 1970s that regulates cooperation in relation to water supply. Part of the solution is the construction of another groundwater pumping station in Schaan
The existing groundwater pumping stations in Wiesen and Unterau will not be able to cope with the massive increase in water consumption in Schaan for much longer, according to the community release. Zum have announced an increased need for drinking water. On the other hand, the concession for the private water production plant of a large industrial company in Schaan expires in 2030. This means that it WILL also be getting its water from the Schaan public water supply with a delay from this point in time. There is an urgent need for action for the community.
Second groundwater pumping station in Wiesen planned
In 1972, the municipalities of Vaduz and Schaan agreed in a contract that they would jointly build and operate water supply systems, provided these were necessary for the treatment of drinking water. At that time, among other things, the costs for the construction of the Wiesen pumping station and the Mühleholz staged pumping station were borne equally by both communities. This agreement is becoming more topical due to the challenges mentioned.
And according to the broadcast, it is clear for both sides that cooperation is needed again to guarantee the drinking water supply. With an expansion concept for the water supply systems, the municipalities have created the basis for further measures.
As a situation analysis has shown, at least one additional groundwater pumping station is required to cover future water requirements. Due to its proximity to the aforementioned reference points, the municipality of Schaan is an ideal location – specifically the groundwater protection area in Wiesen north of the existing pumping station, the municipality explains. A new transfer shaft and a new stage pumping station will also be necessary to cover the required water demand, as will the expansion of the existing water supply network. And last but not least, an additional water reservoir needs to be built for Schaan in the Obera Forst area so that the fluctuating supplies and the extinguishing water reserve can be guaranteed.
The municipalities of Schaan and Vaduz will invest around CHF 18 million in the new water supply systems over the next five years. According to the rough cost estimate, the share of the community of Schaan is 11.1 million francs, that of the community of Vaduz 6.9 million francs.
