Evac Systems Are Very Environmentally Friendly

At EVDS our aim is to help people achieve their objective of sustainable water usage in the future, to manage the water footprint of their building.

Firstly we believe in Conservation, for over 40 years Evac has pioneered the development of the vacuum toilet, with its ultra-low flush.

We must first use our precious water resources wisely, as it must be remembered that even recycling has an impact on the environment.

Secondly, we are developing effluent Black and Grey water Recycling Water Treatment Systems.

Conservation

One of the biggest savings on natural resources is the dramatic reduction in flush water consumption. A typical Evac vacuum toilet requires just over one litre of water per flush – one-sixth of that used by a conventional toilet. Using less water will bring significant cost savings as water rates rise. Evac toilets have a very low water consumption so the actual amount of sewage produced is reduced – helping to ease the burden of overloaded public sewage plants.

Evac toilets take out up to 100 litres of air on each flush, removing viruses, bacteria and odours from the bowl and into the system enhancing hygiene and personal comfort within washrooms. By encouraging the cycle of air, the toilet accommodation will stay fresh.

Environmental Water Treatment - Is there really enough water on Earth?

Water Footprint is a concept to describe personal water consumption. It is a widely known fact the water is a finite resource. Unfortunately, in the developed world we have taken water for granted as it is provided to us instantly through water fountains, baths, wash hand basins and even ornamental fountains and manmade ponds. Since fresh water makes up only a fraction of all the water on Earth it is a resource we cannot afford to squander.

Evac Systems Are Very Environmentally Friendly. At EVDS our aim is to help people achieve their objective of sustainable water usage in the future, to manage the water footprint of their building Firstly, we believe in Conservation, for over 40 years Evac have pioneered the development of the vacuum toilet, with its ultra-low flush.

The Evac solution minimizes the use of fresh water for toilet flushes. At the same time, it offers you ultimate freedom of piping design. Additionally, the reuse of grey water contributes to a smaller water footprint at your building.

The Evac vacuum toilet uses only 1,2 litres per flush as opposed to 6 -7 litres for the conventional toilet. This means a dramatic reduction in water consumption, savings in water rates and also a reduction in the amount of sewage produced.

The Evac solution also makes it possible to recycle grey waters to be used as toilet flush water.

During each flush the Evac solution takes out up to 100 litres of air. This removes viruses, bacteria and odours from the bowl and simultaneously enhances hygiene and personal comfort in the sanitary facilities. Each Evac solution forms a closed loop. This is particularly important in certain organisations, e.g. hospitals, research facilities and prisons, where the waste must be contained or is considered high-risk.

 

We must first use our precious water resources wisely, as it must be remembered that even recycling has an impact on the environment.

The Total Water Cycle

The Evac vacuum system is able to go one step further by introducing water treatment to the vacuum package, so that the whole process becomes one closed loop, ensuring total security against contamination of other water stocks.
Water enters the building and is used for washing
The resulting grey water is collection by the vacuum system, processed and return to the building for toilet flushing water
When flushed is is then collected by the vacuum system fromthe vacuum toilet for further re-treatment, resuse or disposal
