The Urban Lisbon Living Lab (UL3), created under the framework of TWIST project, has joined with Lisbon Municipality to develop MAARTE project – Monitorização da Aplicação de Água Residual Tratada em Espaços públicos.
MAARTE will develop a new methodology to assess the contamination levels of public green areas irrigated with treated wastewater. It will also assess several bacterial and virus concentrations in grass samples irrigated with potable water, ground water and treated wastewater.
MAARTE is managed by Instituto Superior Técnico and the water utility Águas do Tejo Atlântico also participates as a reclaimed water producer.
