Meeting challenges

A plant for treating domestic wastewater must be low-maintenance, cost-effective and easy to configure for each individual household. It should also work smoothly and reliably, and not lead to any ongoing costs.

The BAAS wastewater treatment plant meets all these requirements and can be used for single person households, for small communities and for large settlements.

The treatment of domestic wastewater in the form of wastewater treatment plants is required by law. It also helps safeguard water resources around the world.

Using water resources responsibly

Water is essential for all life on earth. But there are lots of regions around the world where it is in short supply – over 1.2 billion people do not have access to clean drinking water, for instance.

The BAAS wastewater treatment plant purifies domestic wastewater in an environmentally friendly and natural way. Without requiring any electricity. This gives the BAAS plant excellent cleaning and treatment efficiency and results in unique, high-quality wastewater:

  • drinking water quality II
  • fully biologically purified
  • free from pollutants
  • clean and pure
  • clear and odourless

The benefits of reuse

Water shortages are increasing around the world, so people are looking for ways to reuse wastewater. This is essential now, and it will be essential for future generations too.

  • Water is safe to seep into the soil
  • Wastewater can return to the groundwater and the water cycle
  • No issues with discharging wastewater into rivers, streams etc.
  • Green areas can be irrigated, particularly during droughts
  • Recycled water can be used in various ways as service water, e.g. for flushing toilets
  • Forms the basis for treatment to obtain drinking water

Sustainable and effective

The BAAS wastewater treatment plant is a decentralised alternative to wastewater systems and centralised wastewater treatment plants, making it a more sustainable option. Wastewater is collected, treated and disposed of/processed where it is produced, so there’s no need to set up an expensive central wastewater system. No electricity is used when treating the water – the process is sustainable and near-natural.

How you benefit:

  • Cost-effective and economical
  • No high investment costs
  • Lower operating and maintenance costs
  • Sustainable and environmentally friendly
  • A responsible way to use resources such as water
