Drinking water

Drinking water quality

The water we supply is regularly checked for chemical and bacteriological contamination at source and in the network, and its quality meets the standards laid down by law.

Water analysis report of 02.07.2024

Bacteriological quality

The bacteriological quality of water is assessed by regularly testing for bacteria whose presence in drinking water indicates contamination.

Hardness

Water hardness corresponds to the calcium and magnesium salts naturally present in water. It is expressed in degrees and varies between 0° and 50°.

Nitrates

Nitrates occur naturally in soil and water. Excessive or poorly controlled fertilization can increase nitrate levels in water resources. To be suitable for consumption by pregnant women and infants, water must not contain more than 50 mg of nitrates per liter.

Pesticides

The presence of pesticides in water resources is due to poor control of the products used to protect crops or control weeds. The regulatory value of 0.1 mg/litre is below known toxicity thresholds.

Following the many questions raised by TFA (trifluoroacetic acid) after the publication of a PAN Europe study on TFA contamination of drinking water and bottled water in Europe, the Water Management Administration drew up a FAQ on the subject in July 2024, which you can consult in the document below:

Label

The Ministry of the Environment, Climate and Sustainable Development awarded the "Drëpsi" Gold Label to the Commune of Roeser for its commitment and efforts to control risks in the management of water infrastructures intended for human consumption in March 2023 for a period of 6 years.

Introduced in 2006 by the Administration de la Gestion de l'Eau, the "Drëpsi" label rewards municipalities that have drawn up their technical file in application of the Grand-Ducal regulation of October 7, 2002 on the quality of water intended for human consumption.

The good quality of our drinking water is no accident, but the direct result of the constant efforts made day after day by our suppliers to monitor, maintain and service the various elements of the drinking water network. Added to this are rehabilitation and construction work, as well as regular checks on drinking water quality to ensure a safe supply.

The second-generation "Drëpsi" certificate (from 2023 onwards) differs from its predecessor in particular in the way it is awarded (LuxWSP tool) and in its greater dynamism: there are, in fact, different levels of excellence (platinum, gold, silver and bronze) awarded on the basis of good risk management for the different types of infrastructure (resource, storage, processing, distribution). These levels are designed to reward suppliers and give them the visibility they deserve for their ongoing efforts and commitment to managing their supply systems.

To obtain this certificate, suppliers report in the "Luxembourg Water Safety Plan" (LuxWSP) management tool, set up by the Water Management Administration, the steps taken to identify, control and monitor the risks of water quality degradation throughout the drinking water supply chain, from water catchment to supply to the consumer.

Logo Drénkwaasser From autumn 2006 to spring 2007, TNS ILRES was commissioned by Aluseau to carry out an in-depth analysis of the population's image of tap water and its use. In the first phase, 6 focus groups were held across the country in October 2006, each time with a dozen people to discuss their perception of water. A telephone survey of 1,000 interviews was then carried out in February-March 2007, representative of the Luxembourg population aged 15 and over.

Source of drinking water

The Roeser municipal administration provides its residents with high-quality drinking water. This water is supplied by the Syndicat des Eaux du Sud (SES) and is made up of two-thirds spring water from the Eisch valley and one-third surface water from the Haute Sûre lake.

Annual per capita consumption is 44 m3 of water (2023)

Average daily consumption for the Crauthem reservoir (Roeser, Crauthem, Peppange and Livange centre) is 450 m3 of water per day.

Average daily consumption for the Kockelscheuer reservoir (Kockelscheuer, Berchem, Bivange, Industrial zone Livange) is 540 m3 of water per day.
