Canal de Isabel II calls for responsible use of water in the summer months

  • Reservoirs have 587 cubic hectometres of water, 7.8% below the historical average for this time of year

Madrid’s water consumption last July was 7% higher than that registered a year ago, whereas water reserves in Madrid’s reservoirs continue to fall and are already almost 8% lower than historical levels for this time of year. For this reason, Canal de Isabel II is calling on all the region’s citizens to use water responsibly and efficiently, and it has published water-saving tips on its YouTube channel and website www.canaldeisabelsegunda.es.

The volume in the publicly owned water company’s 13 reservoirs was at 62.3% of capacity, with 587.4 cubic hectometres. This is almost 25% lower than last year’s figure for this time of year, 7.8% below the historical average (70.1%).

Increased consumption in summer and low rainfall have meant that since February, water consumption in the Community of Madrid has increased. Additionally, average temperatures in June and July were higher than a year ago: while June ended with a heatwave that sent average daily temperatures up to almost 32°C, in July the average temperature was 26°C, about 2° higher than the year before. As a result, consumption in the first seven months of 2019 has already been the highest since 2012, at almost 298 hm3 compared to 274 hm3 in the same period last year, 8.9% higher.

This rise in consumption is exacerbated by the fall in water entering the reservoirs since the beginning of the hydrological year last October 1st: in total, rivers contributed 307.2 cubic hectometres 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 Community of Madrid is stable, rising consumption and the uncertain outlook for next hydrological year’s rainfall have prompted Canal de Isabel II to ask citizens to collaborate by using this natural resource efficiently and responsibly since 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 awareness actions to encourage citizens 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 green areas 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 water tanks; 157 wastewater treatment plants; and 615 km of reclaimed water network.
