As part of their commitment to the continuous improvement of services, the La Almunia de Doña Godina Town Council (Zaragoza) and FACSA, the company that manages the water supply and sanitation services in the municipality, presented the Sewerage Network Master Plan in the Town Hall's plenary hall. The event was attended by the mayor, Marta Gracia Blanco; the first deputy mayor, Juan José Moreno; the councilor for Agriculture, Industry, and the Environment, Antonio Campillo; the technical architect, Ester Escusol; the FACSA Area Delegate, J. Ramón Rada; the sewerage network specialist, Cristian Martínez; the FACSA Service Manager in La Almunia, Iván Mairal; and the production manager, J. Javier Pardos.
Among other aspects, the document aims to serve as a guide to support the municipal corporation when drafting projects or carrying out investments that directly affect the infrastructure of the town's sewer network, which has an approximate length of 38 kilometers and is used for the evacuation of wastewater and rainwater generated in the urban center.
In order to adapt the sewerage network to the demographic growth forecasts and the possible increase in the urbanized area, the General Urban Development Plan (PGOU) has also been integrated into the content of the Sewerage Network Master Plan.
For the drafting of the document, a field study has been carried out in order to collect and analyze multiple data, which have allowed a diagnosis of the current state of both the network and the service itself.
On the one hand, the behavior of the network has been simulated to verify certain parameters during different rain episodes and short, medium and long term solutions have been proposed that will guarantee its correct functioning.
Furthermore, sections of the infrastructure with the most significant problems have been identified, and solutions have been proposed based on a comprehensive network approach. In this regard, the necessary works have been defined and assessed, and different levels of priority have been established for the various actions.
Most of the work is related to the implementation of improvements in the collectors and the renewal of points in the networks that are in poor condition or that present possible deficiencies in their operation.
In turn, sections with adverse slopes or very low slopes have been identified where accumulations of water and/or sedimentation of coarse materials tend to occur, with the aim of proposing improvements that contribute to solving these problems.
The document also proposes solutions aimed at improving the urban drainage system, as well as evaluating the hydraulic balance system to facilitate the establishment of proper control of discharges and the identification of significant volumes of water that are incorporated into the sewer network, in order to guarantee their proper management and channeling.
