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.
