Wastewater

Surface and wastewater cadastres

We create or revise rain and wastewater cadastres and thus create a solid basis for further processing. Precise and carefully maintained cadastres and sewer databases are the basis for new plans or sewer renovations, especially in urban agglomerations.

Wastewater collection and transport

Construction measures in the field of waste water collection and transport and their dimensioning are often dominated by regional factors. Due to heavy rainfall in some of our African project countries, there is often no mixed sewerage, but only separation sewers. The customary approaches to the amount of precipitation water and the approaches to water consumption must be determined precisely for the estimation of the amounts of precipitation and dirty water for the dimensioning of the sewers and the structural installations. GAUFF Engineering identifies the correct dimensioning of the sewers while paying particular attention to the local conditions.

In addition, we also create condition assessments and sanitation concepts for federal properties in Germany.

Sewage sludge disposal and use

In order to stabilize sewage sludge at an outside temperature of 30 degrees Celsius, a different process is required than at temperatures of -20 degrees. GAUFF Engineering takes this into account, also in order to ensure a later use of the sewage sludge, which is mostly thermally utilized in dried form. The recovery and recycling of substances such as phosphates from waste water and sewage sludge will increasingly play a more important role.
