The wastewater treatment plant has a maximum treatment capacity of 8,580 m3/d and serves a population of 45,257 inhabitants, located in the parish of Areosa, municipality of Viana do Castelo.

Wastewater of urban origin from the municipality of Viana do Castelo is treated using activated sludge in conventional aeration, later reaching a final stage of disinfection by ultraviolet radiation before being discharged into the Atlantic Ocean.

The contract for the “Acquisition of Locksmithing Services for the Pumping Stations of the Ave and Vila do Conde Sul Sanitation Subsystems”, with a duration of 1 year, has a value of 84 thousand euros.

The main objective of this contract is the acquisition of specialized locksmith labor services, as well as the supply of materials and accessories necessary for the execution of the foreseen works.
