World leaders in vacuum sewerage systems; Iseki Vacuum Systems Limited is based in the United Kingdom from where it markets the vacuum sewer technology world-wide. Recently launching the "Redivac" trade name Iseki Redivac provides the expertise required for developing and supporting the technology throughout the world-wide markets.
This engineering expertise has been developed over the past 15 years and during this time Iseki Redivac’s engineers have gained a wide understanding of the potential uses of their vacuum systems and have applied this experience to many differing applications.
With a broad staff base covering many disciplines, Iseki Redivac is able to offer clients services which range from initial project appraisals through to commissioning and handover of their vacuum systems.
A Redivac vacuum offers many advantages for rural communities:-
We use shallow, narrow trenches which means that they can be easily excavated, which speeds up the construction of the project in the first place.
The use of the small bore polyethylene piping allows construction of a pipe network which can reach all the site areas without the need for large and deep collector pipes. Our vacuum system can be integrated with existing gravity systems and septic tanks. This is also useful as it can designed to accommodate future phases of increases to the site.
Our rural community main sewage system is sealed and contained so it will reduce any contamination and provide a sound environmental solution. The installation can be done with little disruption to residents, traffic and businesses.
Vacuum fluid collection systems can be employed in a varirty of situations. Roof drainage is an example of the versatility of the technology. A vacuum system for roof drainage will allow storm water to be taken to the back of the roof and then it will be taken to the ground level. This means that down pipes at the front of the roof will not be needed, This leaves a clear and unobstructed front elevation. Not having down pipes at the front of the roof is also aesthetically appealling to viewers.
Camp & caravan sites
Our system is ideal for camping and caravan sites because of the speed of installation and lack of disruption. Installation can be done in quieter winter season thus not interfering with high season business. Redivac's system is designed to manage varying flow rates throughout the high and low seasons. Normal maintenance issues associated with a traditional gravity system can then be avoided.
The Redivac vacuum sewerage system can easily be connected to existing gravity systems and can be increased as the camp site expands. The system can also collect from single static caravans, toilet blocks, touring caravan emptying facilities and laundries. This is done by using shallow laid small bore polyethylene pipe, negating the need for deep and expensive collector pipes, especilally in a rocky environment.
The system includes the flexibility to locate the vacuum station anywhere on the site and having the collection points located wherever the need for electrical power.
Developers are now having to turn to less suitable land with poor ground conditions as new housing development demand grows. Where there is low population, unfavorable subsoil, a high water table, reclaimed or capped sites, traditional sewerage systems based on gravity are difficult and prohibitively costly options.
In problem areas our vacuum sewerage system can be the most reliable and economical solution for the collection of waste water. Using a sealed vacuum system, the entire network of Redivac's pipes can be put in shallow trenches, usually 1 metre below ground avoiding the need for special excavating equipment. This results in a the reduction of construction costs of traditional gravity system.
Redivac's vacuum sewerage system is extremely adaptable and flexible, allowing for phased development enabling capital expenditure to be easily controlled. The vacuum station can be positioned almost anywhere on site and future developments are easily connected without the need for expensive lift stations or large trunk sewers.
All Redivac systems offer low maintenance and are extremely reliable. Redivac offers a full technical back up service and on site training of your engineers.
Old towns and narrow streets have difficult access that restricts the use of heavy plant and machinery used in the construction of traditional sewerage systems. A Redivac vacuum sewerage system is the solution, as it uses narrow, shallow trenches for the small bore pipes used. This allows lighter plant equipment to be used during the construction of the project.
Smaller trenches offer a cost saving on excavation and a reduced installation time. It also can permit hand digging if access by mechanical diggers is restricted. Furthermore, the flexible piping allows the system to fit around existing services including telephone and electrical cables.
The villages of Tai Wai and Tai Po in Hong Kong, are examples where a vacuum sewage system has been installed overcoming these access issues with great success. Redivac vacuum sewerage system allowed 400 buildings to be connected to the mains sewerage system, this allowed the previous septic tank system to be redundant. Where points of access were difficult, some of the trenches were dug manually and the flexibility of our small bore sewage pipes used allowed complex pipe runs to be put in.
The substantially reduced installation costs and the need for fewer pumping stations made the Redivac sewerage system the right choice.
Our Vacuum sewerage and effluent collection systems are a fantastic alternative to conventional methods on large sites. Redivac Systems can be used on hospital sites where the flexible characteristics of the small bore polyethylene pipe used, brings down the construction costs and minimises disruption. Also, it is a completely sealed system, virtually eliminating the risk of contamination.
The Redivac systems incorporates shallow trenches that are excavated without the need for heavy equipment. The flexibility of our system makes it an ideal choice for the retrofit or upgrading of established hospital sites. It can also be easily expanded in line with the hospital expansion.
Our vacuum sewerage system is a proven environmental solution used in installations around the world for the last 25 years.
The versatility of the Redivac vacuum sewerage system allows for flows to be collected from large shopping centres and large business parks. The system is made up of a network of small bore polyethylene pipes that are used to collect sewerage from around the sites. The pipes are put into shallow trenches thus keeping construction costs down and disruption is kept to a minimum.
Choosing the Redivac system will allow areas where narrow access is restrictive, to be reached without the need for deep dig, normally associated with the conventional gravity systems. Only fairly lightweight construction equipment is needed, keeping the cost to a minimum and reducing the environmental impact.
The flexibility of our system allows for expansion to meet any future development changes to the site as well as being a proven solution for the environment.
Deteriorations of ground conditions often lead to developers turning to our types of sewerage systems as a replacement for failed traditional gravity systems. The advantages of the Redivac systems is they don't rely on gravity falls, with our vacuum mains being laid parallel to the ground level with nominal cover. Digging deep excavations are not required and installation can be carried out with very little disruption to the ground below.
Redivac systems can be fully integrated with existing systems. Flows can be diverted over a specific time period and it is possible sometimes to convert existing gravity manholes to house our equipment. Flows, alternatively can simply be intercepted upstream by using new shallow valve chambers.
The flexibility of the Redivac vacuum sewerage system makes it the choice for the replacement or upgrading of conventional gravity systems, with minimal interference to groundwork and giving fast installation times.
The flexibility of our sewage system will allow sewers to be laid above ground level between buildings. This will allow underground obstacles to be bypassed and will avoid excavating existing concrete flooring which would be very costly. The Redivac system can easily be connected to existing gravity systems and future expansion and development of the factory site can be factored into the system.
The versatility of our system allows vacuum stations to be positioned anywhere on the factory site and it may even be possible to utilise existing buildings. The flexible nature of the small bore polyethylene pipes will allow the pipe network to be constructed at shallow levels, without the need for large and deep collector pipes. Redivac's systems are sealed and pneumatically controlled to stop air leakage thus eliminating any risk of ex-filtration. Collection points can be located anywhere on the site without needing connections to an electrical power source.
Speedy installation and minimal disruption to your factory site means Redivac vacuum sewerage technology is the choice for you.
Our sewerage technology can tackle problems associated with the low temperatures in Arctic communities. The system transports relatively low flows of sewage from individual properties at speed through small bore pipes to the vacuum collection station without the sewage freezing. We do this by fitting each property with an interface valve, usually located in the bathroom.
Deering, Alaska is an example of the successful application of a vacuum sewerage system in an arctic community. This small village consists around 50 houses and a school with difficult access. The village can only be approached by sea or air as well. This Redivac system was constructed using foam insulated polyethylene pipes, just above the permafrost. Glycol trace heating was installed to prevent the pipes freezing at the temperatures of minus 50 Degrees Celcius!
The installation of sewage mains systems in arctic communities needs a versatile system with easy and simple installation making the Redivac vacuum sewerage system the choice for you.
Our vacuum fluid collection systems can be used as temporary or permanent solutions for collecting leachate from landfills. It enables the collection of the leachate inside a sealed system without the fear of ex-filtration.
Another advantage is the option of skid mounting the central vacuum station to ease the installation and reuse. The vacuum station is powered by a generator and this is the only part of the system requiring electrical power. More flexibility is achieved with small bore polyethylene piping which avoids the need for deep excavation associated with gravity systems.
The reduction of investment costs makes the Redivac vacuum system a highly viable option. The system and its reliability and proven track record make Redivac system the perfect solution.
A Redivac vacuum sewerage system can provide the solution when the sewage system needs to extend across water or a railway. The vacuum technology will suspend the sewer pipes from the underside of bridge superstructures eliminating the the deep trenches necessary for traditional systems. It is possible to design the layout of the pipes to make this lift which would not normally be possible with a traditional system.
Many river, lake and coastal communities relying on septic tanks for sewage disposal are looking to introduce a mains system. With a vacuum sewerage system, they are reducing the environmental contamination and pollution of the surrounding watercourses in comparison to inefficient or dysfunctional septic tanks. When comparing the installation cost of our system and a traditional one in these communities, the vacuum system is often found to be the most suitable. There are cost savings associated with installation and the use of vacuum technology can often lead to a reduction in the number of pumping stations required.
