Canal de Isabel II reminds customers of the need to make efficient use of this natural resource with small gestures at home

  • Rainfall and lower temperatures than this time last year helped keep consumption down last month
  • Reservoirs have 536 hm³ of water, 7.9% below the historical average for this time of year.

Water consumption by Madrid area residents this August was 1.1% lower than the same month last year, helped by lower average temperatures than in August 2018 and rainfall much higher than the historical average. Over the same period, the water reserves in Madrid’s reservoirs continued to fall and are already almost 8% below historical levels for this month. For this reason, Canal de Isabel II is calling on all the region’s residents to do their part and use water responsibly and efficiently, and it has published water-saving tips in its YouTube channel and website www.canaldeisabelsegunda.es.

The volume in the publicly owned water company’s 13 reservoirs at the month’s end was at 56.9% of capacity, with 536.6 hm³. This is almost 25.4% less than last year’s figure for this time of year, 7.9% below the historical average of 64.8%.

So, in August consumption fell for the first time since February: last month, Madrid area residents consumed 47.8 hm³ of water compared to 48.3 in 2018. This fall is due to average and maximum temperatures almost two degrees lower than those of the same month last year and rainfall 42.3% higher than the historical average. In fact, 81% of the total rainfall for the whole month fell on a single day, August 26, and the total rainwater collected in the Madrid metropolitan area in August was 64.7 mm, compared to 0.7 mm the previous year.

However, although water consumption in August was down slightly, overall consumption since the start of 2019 is the highest since 2012, with 345.9 hm³ of water for domestic use: a figure 7.4% higher than the consumption recorded in the first eight months of 2019.

This rise in consumption, just a month from the end of the hydrological year, is exacerbated by the fall in water entering the reservoirs since the beginning of the hydrological year last October 1st: in total, rivers contributed 313.1 hm³ of water to these reserves, 58% less than the 105-year historical series recorded by the publicly-owned water company.


Although the water supply situation in the Madrid area is stable, rising consumption and the uncertain outlook for next year’s rainfall have prompted Canal de Isabel II to ask residents to collaborate by using this natural resource efficiently and responsibly: Small gestures by a large community can help to slow the upward trend of recent months.

For this reason, and within the framework of line 1 of its Strategic Plan to ensure supplies for the region’s residents, Canal de Isabel II is carrying out a programme of actions to increase awareness and to encourage residents to consume water responsibly, through its social media channels and its website.

The publicly owned company is also working continuously on actions to conserve drinking water supplies, such as promoting the use of reclaimed water for irrigation and industrial uses, and annual plans to renew the pipe network, which have reduced leakage by 70%.

Canal de Isabel II was founded almost 170 years ago to supply water to the city of Madrid and today it employs over 2800 people who work every day to serve more than 6 million people in the region. It is an innovative publicly owned company, a leader in its sector and recognised worldwide for its management of the integrated water cycle.


It operates 13 reservoirs; 78 groundwater catchments; 17,601 km of water supply and distribution network; 131 drinking water and 133 wastewater pumping stations; 15,083 km of sewage networks; 65 storm tanks; 157 wastewater treatment plants; and 615 km of reclaimed water network.
