The LIFE ECOGRANULARWATER Project is a “Drinking water” project approved within the “Environment and Resource Efficiency” focus area of the 2016 Call of the LIFE Programme.

It aims to demonstrate the efficiency of technology based on biological methods for the removal of nitrates, phosphates, pesticides and other pollutants from groundwater supplies for human consumption. The project proposes a low-cost technology solution for municipalities affected by this environmental problem.

The project will be implemented by a partnership integrated by the University of Granada (Spain), Aalto University (Finland), Construcciones Otero Company (Spain) and the Provincial Council of Granada (Spain), which acts as partnership coordinator.

The proposed technology will be installed in the municipality of Torre Cardela (Granada province), where high levels of nitrate concentration have been detected in the groundwater supply. At current, a reverse osmosis system is being used in compliance with the RD 140/2003, which establishes the health criteria for the quality of water used for human consumption, as well as Drinking Water Directive 98/83/UE and Directive 2013/39/UE, (amending Directives 2000/60/UE, Water Framework Directive, and 2008/15/UE priority substances in water policy). The project will be developed between the 1st of September 2017 and the 31st of October 2020.

Water bodies pollution by nitrates and other pollutants are mainly caused by excessive or inadequate use of fertilizers and plant-protection products in agriculture. Between 2011 and 2015 two of the partners of this project (Granada University and Provincial Council of Granada), together with two local companies (Paisajes del Sur and Bonterra Ibérica) carried out the EUTROMED LIFE project. Among others actions, preventive measures aimed to the optimization of nitrogen fertilization by the farmers were developed. The objective was to avoid nitrate pollution in water bodies. In this way, the Provincial Council of Granada has been working through new projects supported by the Network of Municipalities from Granada Province towards sustainability. More info at


LIFE ECOGRANULARWATER present on the small screen

ConCiencia, the Canal Sur programme, has dedicated a space to this interesting project that affects such a basic good as drinking water.

Complete installation of the prototype of the LIFE ECOGRANULARWATER Project

This second phase has consisted in the expansion of drinking water treatment capacity with the proposed aerobic granular system, expanding the number of bioreactors.

ConCiencia, an informative Program from Canal Sur TV will dedicate a space to LIFE ECOGRANULARWATER project

This is a bi-weekly, 30-minute channel on Canal Sur Television, which deals with current scientific issues as well as innovative projects developed in Andalusia.

The economic sectors that consume the most drinking water would benefit most from ECOGRANULARWATER technology

Households, the food and chemical industries, along with tourism, are the activities that could most benefit from the implementation of the LIFE ECOGRANULARWATER project technology in the Mediterranean countries of the European Union.


LIFE ECOGRANULARWATER receives the virtual visit from the external monitor in june.

The health crisis has led to an adaptation of the visits to the LIFE projects by the external monitoring team. Thanks to the new communication technologies, last June 17 and 18, the LIFE ECOGRANULARWATER project received a virtual visit from Borja Domínguez, our external monitor.

Microorganisms continue confined in the bioreactor, removing nitrates.

In the first phase of the prototype, the efficiency of the system has been demonstrated. The granular system removes by 80% of the nitrates dissolved in the water.
