Why choose a vacuum toilet

As air – rather than water – is used for flushing, vacuum toilets use just 1.2 litres of water per flush, compared with around 6 litres for a traditional toilet: a water saving of 80 per cent! In this way, vacuum toilets help to save water and make smarter use of natural resources.

Thanks to the thin pipes and the fact that no continuous gradient is required, a vacuum system is easy to install. Just as with a traditional toilet, the frame and vacuum toilet are perfectly matched. The technology is built into the ceramic body of the toilet bowl, which is simply connected to the frame and pipework.

Vacuum sewerage systems and vacuum toilets contribute to new sanitation systems, in which water, energy and raw materials are used and reused as efficiently as possible. Instead of flushing away waste water with litres of drinking water, new sanitation systems focus, amongst other things, on water conservation and raw material recovery. In this way, vacuum toilets offer an effective solution for saving water.

Modern vacuum toilets are quiet, use very little water and are reliable in use. This makes them suitable for a wide range of projects, from residential and non-residential buildings to the healthcare sector and the shipping industry.

Vacuum toilets and vacuum sewerage systems represent a significant step towards new sanitation. New sanitation is a sustainable way of separating wastewater at source, recovering raw materials and saving energy. The key features are: the separation of black water (toilet) and grey water (shower and washing machine), the local treatment of water, and the reuse of valuable substances such as phosphate and heat.

Instead of flushing waste water away with large quantities of drinking water, vacuum toilets use air and 1.2 litres of water to transport the waste. As the waste is delivered in a more concentrated form, raw materials can be recovered many times more efficiently. Vacuum toilets use 80 per cent less water and thus help to reduce daily drinking water consumption.

Vacuum sewerage systems and vacuum toilets are ideally suited to hospitals and laboratories. Each flush draws in 65 litres of air, which prevents the spread of aerosols. As the system operates under negative pressure and uses air as the transport medium, there is no risk of leaks from which contaminated liquids could escape. This makes vacuum technology particularly suitable for departments such as oncology and laboratories.

In commercial buildings such as offices, hotels, airports, train stations, and multi-tenant buildings, restrooms are used intensively every day. Traditional toilets use 4–6 liters of water per flush, which – with thousands of users per day -results in a massive demand for drinking water. With vacuum sewer systems and vacuum toilets, you’re choosing a future-proof alternative: hygienic, flexible, and saving up to 80% in water. In large buildings or locations with high toilet usage, the potential savings amount to millions of liters of water per year.

Vacuum toilets are suitable for detached houses and residential buildings, whether in new-build or renovation projects, and offer the same level of comfort as standard sanitary facilities, but with significant water savings.

Vacuum toilets are ideal for events, temporary accommodation, care units and construction sites, where flexibility and reliability are key. The systems can be quickly installed and removed, connected via a plug-and-play system to a central vacuum station or tank, and use very little water, thereby minimising the logistical impact.

Vacuum toilets and vacuum sewerage systems offer a range of benefits for renovation, conversion and repurposing projects. Construction can be carried out more quickly, and the central shaft is no longer the starting point for the design. This makes it easier to convert office buildings into residential properties, and in the case of listed buildings, it is simpler to preserve historical and structural elements. Less material is used, and less space is required for pipework because the pipes are thinner and no gradient is required.
