The Grand Case vacuum sanitation project in the Grand Case neighbourhood uses an innovative technology for collecting waste water. This is a system for extracting waste water in vacuum pipelines. This technology is an ideal solution for beach areas. This makes it possible to avoid increasing the number of waste water lifting stations in urban areas. The technology used is manufactured by FLOVAC in the Netherlands.
The main work carried out by Razel Water Solutions is:
- constructing and installing a vacuum and pneumatic waste water pumping station;
- supplying and installing 81 collection and suction manholes;
- supplying and laying of 3675 m of vacuum sewerage pipes, 1320 m of gravity sewers, 1260 m of waste water discharge pipes and 1360 m of pressure pipes for drinking water supply.
