The Ministry of the Environment and Climate has published a series of guidelines to prevent water wastage during the heatwave and dry period.

Luxembourg's waterways are experiencing a "worrying" situation after a prolonged period of heat and low rainfall. Earlier this week, the Water Management Authority published a statement warning of the "critical situation" of the Grand Duchy's rivers and streams, advising people against fishing or withdrawing water from any surface water, even with an authorisation.

The ministry has also shared a list of recommendations for watering plants, washing vehicles, managing above-ground swimming pools, as well as some behaviours to avoid at home:

  • Watering or irrigation: lawns do not need to be watered. According to the ministry, lawns can withstand prolonged periods of drought and will turn green again with the next rainfall. It is best to irrigate vegetable patches in the early morning or late evening when the soil is cool in order to avoid evaporation or a thermal shock for the plants.

  • Vehicle washing: washing your car at home is a very water-intensive activity and strongly discouraged during periods of drought. However, professional car washes are still operating, as these function within a closed circuit and "recycle" the water used.

  • Above-ground swimming pools: many above ground/inflatable pool models can hold up to several cubic meters of water. During particularly hot days, it is common for a large number of residents to simultaneously fill their swimming pools, thus creating peaks in consumption. In addition, for reasons of hygiene, pool water must be changed regularly or treated with chemicals, such as chlorine. The public are therefore strongly recommended to use public swimming pools instead of putting up pools at home.

  • At home: a filled bathtub represents on average 150 to 200 litres of water, while a 5-minute shower uses approximately 80 litres of water. It is therefore advisable to take showers instead of baths. Shower consumption can be further reduced by turning off the water while soaping up. Getting into the habit of only running the washing machine and dishwasher at full load will also have a positive impact on water consumption and electricity bills.
