Redivac applications

The versatile nature of the Redivac vacuum fluid collection system allows for flows to be collected from sprawling shopping centres and large business parks. The Redivac system comprises of a network of small bore vacuum mains that can be used to connect food outlets and toilet and shower facilities alongside the commercial outlets.

Introducing an Iseki Redivac vacuum system to act as a main sewage in a rural community has a number of advantages. Installation is rapid and manageable due to the shallow, narrow trenches inherent with the technology. The flexible characteristics of the small bore polyethylene piping used permits the construction of a pipe network reaching all areas of the site without the need for large and sometimes deep collector pipes and the system can be integrated with existing gravity systems and septic tanks whilst managing flows from new developments. Furthermore the system can be designed to accommodate future phases of expansion to the site.

The use of vacuum fluid collection systems can be employed in a wide range of situations. Roof drainage is one typical example of the versatility of the technology. Choosing a vacuum system for roof drainage allows storm water to be lifted to the back of the roof for disposal to ground level. This is often very sought-after in arenas as it eliminates the requirement for down pipes at the front of the roof, thus leaving an unobstructed view for spectators. Eliminating down pipes at the front of the roof may also be desirable for the aesthetic appeal of buildings.

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.

The deterioration of ground conditions can often lead to developers turning to vacuum sewage systems as a replacement for failed gravity systems. The vacuum systems offered by Redivac do not rely on gravity falls, with vacuum mains being laid parallel to the ground surface at nominal cover. Deep excavations are therefore not required and installation can occur with minimum disruption at a level above the unfavourable ground conditions.

The versatile and environmentally attractive nature of vacuum technology often presents a viable solution when faced with difficult circumstances. Old towns with narrow streets often do not allow sufficient access for the essential trench digging machinery required for conventional gravity sewage systems. Due to its requirement of only simple trenching at shallow depths, a vacuum sewage system can be the ideal alternative.

In modern times, development has already occurred on many of the sites desirable for the construction of housing. This has lead to developers increasingly turning to sites with less favorable conditions for new housing.  In areas of low population, unfavorable subsoil, high groundwater table and slight decline of the ground, tradition sewerage systems based on gravity transport would lead to high investment costs. In these areas, the vacuum sewage system offered by Redivac is often the most feasible and the most reliable solution for the collection of wastewater.

Vacuum fluid collection systems can be employed as a temporary or permanent solution to the collection of leachate from landfills. The nature of the vacuum technology permits the collection of the leachate in a sealed system without the fear of ex-filtration. Other advantageous characteristic of the Redivac system include the option of skid mounting the central vacuum station for ease of installation and reuse, powering the vacuum station by portable generator and the lack electrical power required for the collection points.

Vacuum sewerage and effluent collection systems offer an attractive alternative to conventional installations. Large sprawling sites such as hospitals are typical examples of developments that can take full advantage of the benefits offered by a Redivac vacuum fluid collection system.

Vacuum sewage technology is often found to be the most suitable option when considering the installation of a sewage system in factories. The inherent flexibility of the Redivac systems allow sewers to be laid between buildings, bypass underground obstacles and even pass through warehouses. The system can intercept from existing gravity systems while managing new flows from expanding premises and it can usually be extended to accommodate any future expansion of the factory.
