Canal de Isabel II opens up four of its treatment plants to students on World Water Day

 • The event, promoted by the United Nations, is focused this year on the importance of sewerage
• Canal de Isabel II will use reclaimed water to improve the quality of rivers in Madrid
• Some 14,000 kilometres of sewers and 157 treatment plants enable 100% of waste water in Madrid to be treated

Canal de Isabel II joined in the commemoration of World Water Day today by showing a group of 220 secondary school students from the region how waste water is treated. Promoted by the United Nations, this event is held to highlight the importance of water and the need to use this scarce resource efficiently and sustainably.

This year, World Water Day is focused on the treatment of waste water. Hence, the public utility opened up the doors to the El Endrinal Treatment Plant in Collado Villalba, the Tres Cantos Treatment Plant, the Torrejón de Ardoz Treatment Plant and the Arroyo Culebro Cuenca Media Alta Treatment Plant in Pinto.

At the latter, schoolchildren from Centro Barrio Loranca in Fuenlabrada were accompanied by the chairman of the public utility and Councillor for the Presidency, Justice and Government Spokesperson of the Regional Government of Madrid, Ángel Garrido, who highlighted the importance of sewerage systems “for properly treating waste water and returning it to the ecosystem in the best possible condition, thus closing a balanced and sustainable cycle”.


During the tour of the plant, Ángel Garrido and the students were shown the complex process that waste water undergoes before it is returned to rivers in the best condition. They were also able to learn about the tertiary treatment of waste water, an additional process that improves quality even further so that it can be used for other purposes, such as watering public parks and gardens, street cleaning and industrial activities.

Canal de Isabel II has recently decided to use the production surplus from its 31 tertiary treatment processes to improve the condition of water in rivers throughout Madrid. Hence, 25% of the reclaimed water will be added each year to the water discharged from treatment plants into the rivers of Madrid. Specifically, 125 cubic hectometres of reclaimed water - a volume that equates to the storage capacity of the Valmayor

The initiative will have an annual budget of 1.3 million euros and reaffirms the environmental commitment made by Canal de Isabel II, positioning the sewerage system in the Region of Madrid as one of the most advanced in Spain.

The region has over 14,000 kilometres of sewers, 63 storm tanks and 157 treatment plants, at which approximately 500 cubic hectometres of waste water are treated every year. The company spends over 185 million euros each year on the operation and maintenance of all these facilities, which enable the region to treat 100% of its waste water.


Besides these visits by students to treatment plants on World Water Day, Canal de Isabel II also held a technical conference on the past, present and future of sewerage in the Region of Madrid.

Furthermore, at the Canal Foundation, two classes of students aged between 10 and 12 were able to discover the scope of a cooperation project by Canal Voluntarios (the Canal de Isabel II Corporate Volunteering Programme) on waste water treatment and channelling in Peru. Subsequently, they helped solve a real sewerage problem via a videogame.

Canal de Isabel II was set up 165 years ago to supply water to the city of Madrid. Nowadays, it provides a service to over six million people throughout the region. It is a leading company in its sector and internationally recognised for its management of all stages of the integrated water cycle. In the Region of Madrid, it operates 14 reservoirs, 78 groundwater collection stations, 14 drinking water treatment plants, 17,434 kilometres of inflow and distribution pipes, 131 drinking water pumping stations and 126 waste water pumping stations, 14,018 kilometres of sewer pipes, 63 storm tanks, 823 kilometres of collectors and emissaries, 157 waste water treatment plants and 512 kilometres of reclaimed water pipes.
