The service includes prior cleaning of the wastewater collectors in the municipalities of Fátima, Ourém and Tomar.

This work will be carried out using high-pressure hydro-aspirator equipment. After cleaning, the entire pipe will be visualised using mobile CCTV video inspection equipment. The aim is to understand the real state of the existing infrastructures in these municipalities. The CCTV inspection and cleaning will be carried out over a period of one year and over a length of 96,000 metres of pipelines. In this work, the state of the collectors will be assessed in terms of possible cracks, ovalisations, ruptures, and the condition of the manholes will also be assessed.
