Drinking waterThe 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


Identification of the areas with the greatest potential of transferability and replicability of the new purification technology implemented by Ecogranularwater Life project

One of the main objectives of the LIFE ECOGRANULARWATER project is to ensure the technology developed in Torre Cardela will be capable of being transferred to other municipalities and contributes to the purification of groundwater contaminated by nitrates from agricultural sources, with a lower cost than current systems and with a lower environmental impact.

The Project Partnership of LIFE ECOGRANULAR visit the municipality of Torre Cardela

The Project partners visit Torre Cardela to finalize details about the design of the New Water Treatment Plant.

The Applied Economics Department of the UGR draws up the socioeconomic and environmental analysis of the new water purification technology

Because of supply of drinking water to small municipalities represents a complex issue, different complementary analysis methodologies will be used.

Members of the Life Ecogranularwater Project’s beneficiary entities have signed the Partnership Agreement

On May 22th 2018, members of the LIFE ECOGRANULARWATER Project’s beneficiary entities met at the Advanced School of Civil Engineering of Granada University to sign the Partnership Agreement after a presentation of the progress made so far.

University of Granada is researching with pure culture of denitrifying bacteria

In the preparatory action for the selection of bacteria strains, organic matter source and operational conditions of aerobic granular systems, University of Granada is testing with different species of bacteria, with the aim to identity the better inoculum, carbon source and hydraulic parameter for the higher performance in terms of pollutants removal in drinking water.

We present the LIFE ECOGRANULARWATER Project to the VII GRAMAS Network Assembly

The LIFE ECOGRANULARWATER project was presented at the VII GRAMAS Network Assembly (Municipalities from Granada province towards sustainability) to the municipalities integrated in it. This project represents a great solution for those areas affected by high nitrate concentration in water supply.
