Canal de Isabel II presents the winning bottle design in the competition “De Madrid y del Grifo”


The creators of the winning design will participate this summer in a three-week course at the Istituto Marangoni in Milan.

  • Designed by two students at the Universidad Politécnica, the Claridy bottle is inspired by the Santa Engracia water tower.
  • This initiative aims to encourage people to use tap water and to highlight its excellent quality.

Claridy is the name of the winning project in the design competition “De Madrid y del grifo”. The competition was launched by Canal de Isabel II on 25th March to produce a bottle that can promote the quality of Madrid’s tap water. The winners, Lidia Ruiz Díaz and Clara Rodríguez Ríos, received their prize today at a ceremony held at the Fundación Canal.

The winning project is inspired by the history of the company and, more specifically, by the silhouette of its first water tower. With more than a century of history behind it, it has become one of the most recognisable landmarks of Canal de Isabel II. It allowed supply to be extended to higher areas of Madrid at the beginning of the 20th century.

The competition was open to students enrolled for the 2018-2019 academic year in degree courses in Industrial Engineering and Product Development or Product Design at any school or university in the Madrid Region. After the closing date for entries, nine designs were selected for evaluation as meeting all the requirements specified in the rules.

The jury included representatives of Canal de Isabel II, design experts, glass manufacturers and industrial designers. They praised the aesthetics, ergonomics, and ease of cleaning and functionality of the Claridy bottle compared to the other proposals. This summer, the winners will attend a three-week product design course at Istituto Marangoni, a prestigious design institute located in Milan, all expenses paid (transport, accommodation and full board).

Now that the bottle design has been chosen, Canal de Isabel II will look at how to produce and distribute it from next autumn, to make it available to both institutions and companies, especially hotel and catering companies, and individuals.

The Madrid Region has excellent quality water, and this competition aims to highlight the environmental benefits of consuming tap water. Madrid is the Spanish region with the lowest consumption of non-carbonated bottled water per capita per year, according to figures from the Ministry for Ecological Transition’s Household Consumption Database. While the average for Spain is 59.4 litres per person per year, the people of Madrid consume only 16.7 litres.

Canal de Isabel II has established a strict surveillance and control programme to ensure maximum water quality. Each year it analyses over six million samples of drinking water from collection points and throughout its distribution network.


Using quality tap water not only saves bottled water, it has other important household benefits: less space for water storage facilities, reduced consumption of detergents and personal hygiene products, shorter cooking times (saving energy), easier home cleaning (avoiding lime-scale deposits) and longer average life for washing machines and dishwashers.

This habit not only helps reduce plastic waste and avoid the environmental costs of transporting bottles and bulk containers but also saves on household shopping. In Madrid, a litre of water costs on average slightly over €0.0015, while a litre of bottled water costs on average about 21 cents: 140 times more.


This initiative is part of objective 7 of the Canal de Isabel II 2018-2030 Strategic Plan. This objective aims to enhance transparency, good governance and commitment to society. It includes open and participative activities for groups with which Canal works with, as well as those about to corporate social responsibility.

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