Forward looking aspect
Identified reason(s) for non compliance: 
A Entidade Gestora refere que afluíram à ETAR de S. João da Talha, com regularidade indesejável, águas residuais brutas com componente industrial muito acentuada, cujas características não são compatíveis com a capacidade da ETAR. Esta situação decorre do facto das instalações de pré-tratamento interno das indústrias não assegurarem as condições limite de descarga previstas no Regulamento de Descargas de Águas Residuais Industriais do Município de Loures. Esta situação tem persistido no histórico de funcionamento desta ETAR, mantendo-se o agravamento já verificado em 2015. Não cumpre relativamente aos parâmetros CBO5 e CQO.
Measure(s) to reach the compliance needed for UWWTP: 
A ETAR de S. João da Talha entrou em funcionamento em 1997. A operação da ETAR implementa ações ao nível do tratamento primário, da decantação secundária, e espessamento de lamas, com a adição de reagentes, coadjuvantes de coagulação e de floculação, com o objetivo de minimizar os efeitos das descargas indevidas. Está a ser preparada uma empreitada para ser lançada em 2019 para reparações de construção civil e instalação de novos equipamentos, onde vai estar incluído um novo sistema de arejamento por difusores de bolha fina, que vai aumentar a capacidade de transferência de oxigénio e ajudar a dar resposta aos eventos de cargas orgânicas afluentes anormalmente altas.
