A vacuum sewage system can often provide the ideal solution when faced with the necessity of crossing a watercourse or railway. The lifts possible by using vacuum technology allow sewer pipes to be attached to the underside of bridge superstructures thus eliminating the need for the deep trenches necessary for traditional gravity systems.

Many river, lake and coastal communities who currently rely upon septic tanks for disposal of sewage are now looking to introduce a mains sewerage system to avoid the pollution of surrounding watercourses and to eliminate other environmental contamination caused by inefficient or dysfunctional septic tanks. When comparing the installation cost of vacuum and gravity sewage systems in these communities, vacuum systems are often found to be the most suitable. Not only are there cost savings associated with installation, but the use of vacuum technology can often lead to a reduction in the number of pumping stations required.

The neighbouring French villages of Foucheres and Chappes have both benefited from the installation Iseki Redivac sewage systems. Confronted with Poor ground conditions, challenging topography and the need to cross the River Seiner, the versatile system offered by Iseki Redivac proved to be the ideal choice for both. The systems offered substantial savings in cost together with rapid and manageable installation.
