The municipality of Abegondo will host next Saturday March 25, 2017 the 1st Galician hydrogeology day Edition. This event aims to bring society to hydrogeology and consists of a guided tour, totally free and open to all types of public.
The day entitled “The autonomous supply systems with groundwater of Abegondo” will begin at 10:00 a.m. in the Casa do Concello de Abegondo, from where a bus will go to Vizoño.
The objectives of the visit are to make known:
- Groundwater and its importance in rural Galicia.
- Autonomous systems of groundwater as opposed to centralized systems in the provision of water services in the Galician rural environment.
- Control networks and techniques for the characterization of aquifers and the study of the status and chemical quality of groundwater.
The event is organized by the CICA Water and Soil Group of the University of A Coruña, the University of Santiago de Compostela and the Council of Abegondo under the coordination of The International Association of Hydrogeologists – Spanish Group (AIH-GE).
Students of I.E.S. Viós
On November 30, 2016, 31 students from the 4th ESO moved to Vizoño to learn about the new facilities of the Community of Users of A Malata.
During the visit, they knowed the motivation of the project: to diagnose the water problems of the rural village. In this way, they were able to verify the original state of the fountain of A Freiría discarded by nitrates.
Then, they learnt the best sanitary practices at new wells executed near A Prata’s spring.

Finally, they verified the functioning of the new purification plant.

Once completed the improvement of Community of A Malata, the users have begun to take on the new tasks of managing in order to guarantee the potability of water.

On Friday, November 4, the students moved to Abegondo to learn about the problem of providing water services (supply and sanitation) to the dispersed rural.
The purpose of the visit is a study of alternatives: autonomous vs. centralized.
The day began in the reservoir of Beche, in order to contextualize the huge investments of the centralized infrastructures of supply, and then to show the deficiencies of the current catchments of springs at autonomous schemes.

The solutions proposed for the autonomous model, as a result of the methodology tested by Conesellería de Sandiade, Augas de Galicia and the Concello de Abegondo, were explained on the basis of the following pilot installations carried out under the Life program:
- The piezometer network has made it possible to determine the status (quantitative and chemical) of groundwater as a source of water for human consumption.

- Pozos da Prata (wells). The new catchments have been executed as an example of the physical measures that can be implemented to offer an adequate sanitary protection of the water and Minimize damage to the environment.

- Tank and water purification plant of A Malata. The choice of materials for water storage and purification equipment are designed to facilitate control and maintenance work and will allow the Community of Users to supply potable water in accordance with the requirements of Directive 98/83 / EC

- Sewage treatment plant of Cullergondo – Xuanzo. Regarding the treatment of domestic water, the soft technologies is presented as the best model due the simplicity of the maintenance of this installation would allow the management to be adopted by the Community of Users.

On October 4, 2016, students from the CVC Valladares moved form Vigo to Abegondo to learn about autonomous water facilities tested under the Life program.
On this occasion, the event was planned in three locations and three days: Abegondo, Tomiño and Santiago de Compostela, from Wednesday 8 th to Friday 10 th June.
