Beuth (now part of VDE Verlag) is the official distributor for German technical rules. They offer the ATV-DVWK-A 131E PDF with a digital watermark (your name/company). While not free, it is legally secure and internationally recognized.
While ATV-DVWK-A 131E is a German standard, its principles have been adopted globally because they offer a robust defense against climate change. The standard promotes the concept of "source control" and retention. By accurately modeling the capacity of pipes and the behavior of runoff, it forces engineers to consider
For decades, urban drainage was guided by a simple philosophy: get the water off the streets and into the nearest river as fast as possible. However, as impervious surfaces expanded and extreme weather events became more frequent, this approach led to overwhelmed systems, urban flooding, and severe ecological damage to receiving waters. atv dvwk a 131 epdf top
The ATV-DVWK-A 131E (published by the German Association for Water, Wastewater and Waste, now DWA) represents a paradigm shift. It is the definitive guideline for the dimensioning and design of stormwater sewer systems. Unlike older empirical rules of thumb, A 131E relies on rigorous hydrological modeling and statistical rainfall analysis to design systems that handle flow rates effectively while minimizing environmental impact.
