TWO PUBLIC tenders have been launched by water company Águas do Algarve, relating to basic sanitation in the boroughs of Silves and Vila do Bispo, to win contracts with a combined value of three million euros.
In the borough of Vila do Bispo, the contract allows for the installation of a new water treatment plant at Martinhal and the renovation of the existing water pumping station. The responsibility includes the treatment of sewage provided by the Sagres interception system through an underwater emissary linked to the pumping station. In order to minimise bad smelling odours from the water treatment plant, all parts are confined in a closed space, which is ventilated by a pipe that drives air through for treatment via a biofiltration process.
The work is worth around two million euros and the company that secures the contract will have a maximum of 360 days to complete the project.
Meanwhile, in the borough of Silves, Águas do Algarve will invest around one million euros in constructing a sewage treatment system located in São Marcos da Serra. The old treatment plant will be closed and a new system will take over the service in this area, a place that has been in desperate need of this new type of system. Until now, the sewage water has been discharged into the Ribeira de Odelouca, but this will cease to be the case with the new system.
A total of 270 days is allowed for the supply and installation of the new water treatment system, which will serve a population of around 1,000 people.
