Waste Water

In some developing regions, comprehensive and systematic waste-water disposal is the exception rather than the rule. Under certain circumstances, disposal systems do not always have to meet with European quality standards because in rural developing regions there is usually very little waste water. In greater urban areas, however, poor disposal can have disastrous consequences.

Competent planning and implementation of waste-water disposal systems help to protect habitats and human health.

Surface Water and Waste Water Cadastre

In developing regions with heavy rainfall, surface water is mostly drained through open drain channels. These drain channels often affect the laying of underground ducts. In cases like these, cost-efficient disposal variants are only possible in conjunction with the disposal of surface and waste water.

Collection and Transport

Regional influence factors also dominate collection and transport measures. Due to heavy rainfall, for instance, in our African project countries, there is often no mixed sewerage. Standard approaches in water consumption and the resultant estimation of waste water volume would lead to incorrect dimensions for new systems. GAUFF Engineering identifies the correct dimensions for the waste water canals while paying particular attention to local conditions.

Waste-Water Treatment Plants

Effective waste-water treatment poses different challenges depending on climate zone. Climate parameters have a huge impact on biological treatment. In any case, GAUFF has a host of innovative solutions on offer, not to mention a wealth of knowledge and regional experience.

Sludge Disposal and Recycling

Stabilising sludge at outdoor temperatures of 30 degrees Celsius is a completely different matter than at temperatures of -20 degrees. GAUFF Engineering takes this into consideration in order to ensures that pathogenic germs are reliably killed. This guarantees that the sludge can be either recycled or easily disposed of later on.


Preventing emissions from the existing waste-water grid and the related protection of soil and ground water pertains to the most demanding tasks of operating a waste-water grid.
