The project includes the creation of an artificial wetland area that will function as a green filter and improve the ecological flow of S’Albufera.
The Sa Pobla treatment plant
This Thursday, the board of directors of the Balearic Water Agency approved the award of the contract to the FACSA-Melchor Mascaró S.L. joint venture for the expansion and improvement of the treatment works at the Sa Pobla Wastewater Treatment Plant (WWTP) for 7,098,803.4€ (including VAT).
The works will double the treatment capacity of the current flow, from 2,000 m3/day to 3,850 m3/day. In this way, the station will be able to serve a maximum population of 25,667 people, whereas at present it can serve 15,000 people.
The main actions planned consist of a new pre-treatment system, two biological treatment lines and secondary settling, a digester and a sludge thickener, as well as the remodelling of the dehydration and control buildings. In addition, the existing biological reactor and digester will be adapted as a storm tank to minimise the effects of the arrival of high flows of water during rainfall events that may occur due to the lack of a separate municipal rainwater network. Once the works have been awarded, the completion period is eighteen months.
The new WWTP will have an artificial wetland, which will act as a green filter. This is an additional treatment using a wet zone. In this way, the treatment plant will have an additional treatment of the treated water that will make it possible to reuse the entire flow of treated water for environmental use as an ecological flow for the S’Albufera natural park. The reuse of water will improve the quality of the water in the wetlands.
