In May 2015, Aqualia optimised the infrastructures of El Rocío so that 800,000 visitors could enjoy the
pilgrimage. In just one weekend, 52 million litres of drinking water were consumed. Aqualia tuned
the water infrastructures of the municipality that witnesses its population increase by almost 800 in
several days.

In January, new active carbon filters were installed in the treatment plant to enhance the water quality,
which required an investment of 754,000 euros.
The aim of these filters was to improve the organoleptic properties of the water and to prevent the
possible presence of pesticides in the supplied water, which at times are used on olive groves.

Aguas de Alcázar, company that manages the municipal service of Alcázar de San Juan in Ciudad Real,
presented its Sustainable Management Plan that was launched with the general aim of optimising the
volumes of supplied water.
This plan includes three line of action: improve the infrastructures, systematic monitoring of the
networks, and citizen awareness.

Improved water quality in San Lorenzo del Escorial thanks to the expansion of the Water Treatment
Centre (WTC) that was designed, built and is managed by Aqualia.
The project involves increasing the treatment, decantation and filtration capacity for a flow of 4,000
m3 a day to guarantee an excellent quality flow for a nearby population of 20,000 people and a large
transient population.

Aqualia presented the local authorities of Llucmajor (Mallorca) with the new sewage tanker that will
help improve the municipal water service. It will work daily on scheduled cleaning and preventive
maintenance works of the 103 kilometres of drainage and rainwater networks and their 20 wastewater
pumping stations. The new vehicle will also be used to attend and resolve incidents that may arise
along the sanitation network.

In Ávila, Aqualia has carried out complex re-floating and improvement works on the anchorage of
the floating intake located on the Voltoya reservoir, where the water supply from Ávila is collected.
The floating intake is a mechanism used to collect surface water in reservoirs, designed to be able to
operate at different heights for the purpose of collecting better quality water.

Aqualia has been improving the water service in Sóller (Mallorca) for 10 years. During this time, more
than 6 million euros have been invested in improving the water infrastructures and in renewing the
supply and sanitation network of the municipality.
The supply has decreased from 1,832,694 m3 to 967,012 m3, which means a 47% reduction in the
water required for the service. In addition, performance has increased from 40% in 2005 to currently
84%, and electricity consumption has been reduced by 63%.
