Brussels Institute for Statistics and Analysis (BISA) - In the Spotlight - Per capita water consumption in m³ in the Brussels-Capital Region

This year, the Brussels Institute for Statistics and Analysis (BISA), launched a new online publication entitled “Key figures by municipality” listing the key socio-economic indicators of each of the 19 Brussels municipalities, among which the average water consumption per inhabitant.


Per capita water consumption in m³ in the Brussels-Capital Region in 2017
 


In 2017, 59.5 million m³ of water was consumed in the Brussels-Capital Region. That figure is based on the water consumers were billed for by Vivaqua, the Brussels intermunicipality tasked with the production and distribution of drinking water.

The water consumption billed for includes both household consumption and the consumption by businesses based within the territory. According to Environment Brussels:

  • Also in 2017, Brussels’ households continued to be the largest consumers of water. They account for about 69 % of all the water billed for in the Brussels-Capital Region;
  • The remaining 31% are consumed by the service sector (hospitality, shops, public administrations, schools, social and health activities...) and the industrial sector.


In relation to the population, this translates into an average per capita water consumption[1] in the Brussels-Capital Region of 46 m³ during that year.


The average per capita water consumption in the municipalities in the centre exceeds 50 m³

At municipal level, the average water consumption per inhabitant can vary by as much as 100 %. In 2017, the average per capita water consumption at a local level ranged between 32 and 66 m³.

  • Households and businesses in the City of Brussels and the municipalities of Ixelles, Saint-Gilles and Saint-Josse-ten-Noode on average consume more than 50 m³ of drinking water per inhabitant. It is worth noting though that a large part of the Region’s services industry (the hospitality sector, shops, offices, public administrations, schools, hospitals, sports and leisure facilities...) is based in these municipalities.
  • Conversely, the average per capita water consumption in the north-west of the Brussels-Capital Region and in Schaerbeek and Watermael-Boitsfort remains below 40 m³, which can be explained by the fact that fewer businesses are operating in these municipalities.
  • The average per capita water consumption in the other Brussels municipalities, i.e. those located in the south-west and east of the Brussels-Capital Region, ranges between 40 and 50 m³.


The average water consumption has decreased over the past number of years

Between 2012 and 2017, the average per capita water consumption in the Brussels-Capital Region has decreased. It dropped from 50 m³ to 46 m³ per inhabitant. It decreased in most Brussels municipalities, except in Evere, Anderlecht, Forest and Jette where it stabilised over that same period. According to Environment Brussels, this downward trend can be explained by a greater awareness among households, the use of water-saving devices and water-saving equipment, alternative drinking water supplies, water pricing, etc.
 

 Keen to find out more?

Check out the publication “Key figures by municipality” on the BISA website. It contains the key socio-economic indicators of your municipality, compared to the regional average. Organised by theme, the indicators are presented in the form of tables, in two columns: the most recent figures in one column and the figures on the situation as it stood five years earlier in the other column. The publication “Key figures by municipality” is updated on a monthly basis.
