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.

Furthermore, the flexible characteristics of the small bore polythene pipe employed in Redivac systems allow the construction of the pipe network without the need for large and sometimes deep collector pipes. This reduction in investment costs alone often leads to the vacuum system being the most viable option.

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.

The flexible characteristics of the small bore polythene pipe employed in Redivac systems allow the construction of the pipe network without the need for large and sometimes deep collector pipes. This leads to minimum disruption during the construction phase, making the system ideal for the retrofit or upgrading of existing hospital sites. Should the plan of works dictate phased installation, this can also be accommodated in the Redivac systems, once again highlighting the unique advantages of choosing a vacuum 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.

The versatility associated with vacuum technology allow vacuum stations to be sited almost anywhere on the site with the possibility of even utilising existing plant rooms or other available buildings. The flexible characteristics of the small bore polythene pipe employed in Redivac systems allow the construction of the pipe network without the need for large and sometimes deep collector pipes and the collection points can be located throughout the site without the need for any electrical power at the collection points. It should also be noted that vacuum systems are closed, pneumatically controlled systems with absolutely no leakages thus eliminating the fear of ex-filtration.

Redivac systems have been successfully installed in large factory sites. Such systems often only require one central vacuum station and vitally, due to the fast installation rates, fitting of the vacuum sewerage system can be complete without suspension to the factory’s production.

The speed of installation with the minimum of disruption makes the vacuum sewage systems offered by Iseki Redivac ideal for camp and caravan sites. Installation works can be restricted to the winter closed/quiet season so as not to interfere with high season trade. The Redivac system can be designed to manage the problematic issue of dealing with high season flows while catering for the low season flows thus avoiding the normal maintenance issues associated with the traditional gravity system. The system also has the capability of intercepting existing gravity systems whilst managing new flows from an expanding camp site.

When using a Redivac system for camp and caravan sites, the system can be designed to collect from individual static caravans as well from the services offered on the site such as toilet blocks, touring caravans emptying facilities and laundries. The flexible characteristics of the small bore polythene pipe employed in Redivac systems allow the construction of the pipe network to facilitate this without the need for large and sometimes deep collector pipes. Other advantages of the system include having the flexibility to locate the vacuum station almost anywhere on the site and having the collection points located throughout the site without the need for electrical power. A further benefit of choosing a vacuum system is its capacity to be extended along with future expansions to the site.

The advantages of vacuum technology become increasingly apparent when dealing with certain problematic circumstances. The installation of sewage mains systems in arctic communities is one such situation. These remote communities require a versatile system and ease of installation is often of paramount importance making the system offered by Iseki Redivac ideal.

Furthermore vacuum technology can be used to tackle problems associated with the low temperatures experienced in Arctic communities. Iseki Redivac systems allow the transportation of relatively low flows of sewage from individual properties at high speed through small bore pipes to the vacuum collection station without the danger of the sewage freezing. In such situations, each property is fitted with an interface valve located in the bathroom.

Deering, Alaska is an example of the successful application of a vacuum sewage system in an arctic community. This small village consists of only fifty houses and a school and with no access by road; approach to the village has to be made by sea or air. This particular Iseki Redivac system consisted of foam insulated polyethylene pipes installed just above the permafrost. Glycol trace heating was installed to the foam to stop the pipes freezing at the winter temperatures of minus 50!
