Project UIA03-338

The GUARDIAN project

An innovative urban initiative to increase fire resilience in an area of the Parc Natural del Túria using reclaimed water.

The GUARDIAN project (UIA03-338)

GUARDIAN is a project aimed at increasing fire resilience in an area of the Parc Natural del Túria. The initiative, subsidised by the European Union, has been led by Riba-roja de Túria Town Council and Paterna Town Council, together with Hidraqua, Medi XXI, the Universitat de València, the Universitat Politècnica de València and Cetaqua. The Parc Natural del Túria (Generalitat Valenciana) has also collaborated in the project.

Its actions include the design and construction of a water regeneration plant (ERA) to remove emerging micropollutants, which treats part of the effluent from the Camp de Túria II WWTP. The reclaimed water is used, through water cannons, for the preventive and maintenance irrigation of the green barriers that protect the wildland-urban interface against fire, without using drinking water.

The project has also included the transport and distribution network for the reclaimed water (tanks, pipelines and pumping stations), the monitoring of climatic and agronomic conditions, the restoration of the protected wetland of the La Vallesa reservoir, forestry and vegetation management work, the introduction of fire-resilient species, training for the population in fire prevention and self-protection, a socio-economic analysis of its impact and a study of its replicability in other urban areas.

Urban Innovative Actions

One of 22 projects chosen from 184 across Europe

GUARDIAN was selected in the 3rd Urban Innovative Actions (UIA) call, the European Union initiative that funds new, creative and sustainable solutions to urban challenges (demography, pollution, employment, climate change). In it, urban authorities play a catalytic role in bringing local stakeholders together to face the effects of climate change.

The call closed on 30 March 2018 and, after a rigorous selection process, the chosen projects and their funding – 80% of the budget – were announced in Brussels on 10 October 2018. GUARDIAN was one of 22 projects selected from 184 proposals from 21 countries. In the climate change adaptation category, 43 applications were submitted and 6 were chosen: GUARDIAN, alongside projects from major cities such as Amsterdam, Paris, Barcelona, Manchester and Seville.

UIA projects are led by urban authorities. In GUARDIAN these are Riba-roja de Túria, the main urban authority, and Paterna. They are joined as partners by Hidraqua, Cetaqua, Medi XXI, the Universitat Politècnica de València (IIAMA) and the Universitat de València (Water Economics Group).

Background

A risk that grows with climate change

Climate change has increased the risk of fires and the threat to the so-called wildland-urban interface, where homes and forest intermingle.

Riba-roja de Túria has suffered 40 forest fires and Paterna 19. Their residential estates lie within the Túria Natural Park, where the fire risk is high.

Reclaimed water offers a tool to defend against this growing risk: a resource that is available all year round, does not compete with drinking water and closes the water cycle in line with circular economy principles.

Results

Inaugurated in April 2022

In just over three years, the partners completed the largest fire defence installation using reclaimed water in Europe, and the second largest in the world, inaugurated on 22 April 2022.

  • A water regeneration plant (ERA) designed by Cetaqua and built by Hidraqua, which also supplies reclaimed water to the La Vallesa reservoir to improve this listed wetland.
  • Five tanks of reclaimed water and the pipe network running through the Natural Park, with solar-powered pumping.
  • 40 SIDEINFO towers by Medi XXI and a wireless sensor network that monitors the fire risk in real time.
  • More than 37 hectares of strategic forest management and more than 2,000 native, low-flammability plants.
  • Studies by the Universitat Politècnica de València on the water status of the vegetation to set optimal irrigation patterns, and by the Universitat de València, which estimated the cost of not acting at around 31 million euros.

A replicable solution

GUARDIAN shows that reclaimed water can protect the wildland-urban interface. Let us know if you would like to apply it in your municipality.
