The reformulation of the TABUAS POINT WATER results from the need to address the situation at the level of the deficit treatment currently presented by the treatment plant. In this sense, the construction of an activated sludge-type treatment plant, based on SBR technology, is expected to be built under a prolonged aeration regime. The final discharge of treated waste water will take place in the receiving water environment, Rio Galinhas, a tributary of the Douro River.
