We are involved in the committees of the DWA
At the DWA (German Association for Water, Wastewater and Waste - Deutsche Vereinigung für Wasserwirtschaft, Abwasser und Abfall e. V.) we are actively involved in the working groups (Arbeitsgruppen, AG) of the main committee "Drainage Systems":
- AG ES-5.9 for DWA-M 127-4: Structural analysis of drainage systems - Manholes
- AG ES-5.7 for DWA-M 127-3: Structural analysis of drainage systems - Profiled walls
- AG ES-5.11 for DWA-A 127-11: Structural analysis of drainage systems - Road traffic loads and associated fatigue analysis
- AG ES-5.12 forDWA-A 127-12: Structural analysis of drainage systems - Partial safety factors for the component resistance
All working groups are subordinate to the Technical Committee FA ES-5 Bau. Furthermore, we are appointed by statute to the DWA working group
- AG ES-8.22 for DWA-M 143-6: Structural analysis of drainage systems - Manhole rehabilitation.
Our work influences the regulations
- DWA-A 161 Structural analysis of jacking pipes: yellow print → white print, translations into English, correction sheets
- DWA-A 143-2 Rehabilitation of drainage systems outside buildings, Part 2: Structural analysis for the rehabilitation of wastewater pipes and sewers using lining and installation methods: yellow print → white print, interpretations
- DWA-A 127-10 Material characteristics
- DWA-A 127-1 Basic principles: objections, comments, suggestions for improvement
Since we translate standards into computational programs, we deal with the contents in depth.
We are involved in the GSTT
At the GSTT (GERMAN SOCIETY FOR TRENCHLESS TECHNOLOGY E.V.), we deal with the "Requirements for pressure pipe liners" in the working group GSTT-AG 20-2:
Together, we engineers are developing a set of rules for the structural design of liners that are installed in drinking water and wastewater pressure pipes during renovation.
We are involved in committees of the DIN
As a company, we support the German Institute for Standardization (DIN) in the following committees
- DIN: Standards Committee NA 119-05-37 AA - Renovation, repair and renewal of drains and sewers (CEN/TC 165/WG 13, CEN/TC 155/WG 17 and ISO/TC 138/WG 12)
- CEN: CEN/TC 165/WG 13 - Renovation and repair of drains and sewers
We are involved with the DCA
Within the framework of the "Arbeitskreis Baugrund" (task force buildung ground) of the DCA: Verband Güteschutz Horizontalbohrungen e.V. - Drilling Contractors Association and the GSTT we support the two associations in the development of a technical assistance, among others for the interpretation of soil reports and homogeneous areas.
