A new Flovac vacuum sewer system is being installed in the millenary towns of Arazede and Liceia in the municipality of Montemor-o-Velho in Portugal.
Our client ABMG (Águas do Baixo Mondego e Gândara), the main water and wastewater utility for the region, has made this video showing the installation.
One vacuum pump station will serve over 230 house connections in this millenary area. Over 12 km of PEAD PN 10 vacuum mains, sized from 110 to 200mm, are being installed in the ground. All the Flovac collection pits are fitted out and tested prior to delivery to the project office.
Grupo MMPS -who are doing the installation- are the Flovac representative in Portugal and have completed a number of vacuum sewer projects making them the most experienced vacuum sewer company in Portugal and a key reason for them being awarded the project.
The critical reason why vacuum was chosen for the project was for the protection of groundwater. Knowing that sewage could not leak out of the piping network was a key driver for the install.
More than 170 vacuum collection pits with Flovac valves were installed into this old community which dates back nearly 1,000 years.
