Luxembourg's per-capita consumption of water averages slightly over 200 liters per day. Could the country eventually run out of drinking water if the current growth rate continues?

In their parliamentary question conservative (CSV) MPs Diane Adehm and Gilles Roth asked Environment minister Carole Dieschbourg what needs to be done to avert a potential disaster scenario.

Luxembourg's drinking water is provided mainly by underground water sources and by the Upper-Sûre lake.

While the per-capita consumption has decreased in recent years, there has been an increase in overall consumption due to the country's demographic and economic growth, Dieschburg explained. In her answer she revealed that Luxembourg's daily water consumption currently amounts to 120,000 cubic meter, which translates into a per-capita consumption of 202 liters per day.

The minister also highlighted the expected negative impact of rising temperatures on water supply.

According to Dieschburg the protection of water resources against pollution is key to avoid future water shortages.

In 2016 parliament approved a financing act for the construction of a water treatment plan aimed at improving and expanding the provision of drinking water. The new plant will allow SEBES - the drinking water network of the Upper-Sûre lake - to increase its current drinking water production from 38,000 to 110,000 cubic meter per day. In her answer Dieschbourg underlined that raising public awareness remains nonetheless crucial in order to prevent future shortages.

Several studies have been conducted in the past years, and more will be done in the future to analyse which resources are needed to secure Luxembourg's drinking water provision, the Minister added in her answer to the parliamentary question.
