The standard is structured into clear chapters that guide the user through a systematic design process. According to the documents, the table of contents includes the following main sections:
The standard calculates required volumes for both aerobic and anoxic zones to manage nitrogen reduction. 2. Secondary Settling Tank (SST) Design

The is a critical, internationally recognized standard for the design and dimensioning of single-stage activated sludge plants for wastewater treatment, particularly focusing on nitrogen reduction . Originally developed by the German Association for Water, Wastewater and Waste (ATV), and updated by the DWA (German Association for Water, Wastewater and Waste Management), this worksheet provides robust guidelines for sizing both biological reactors and secondary settling tanks (clarifiers). The standard is essential for engineers involved in: The standard is structured into clear chapters that

The standard's global relevance is further demonstrated in a 2025 research paper from MDPI that uses the ATV-DVWK-A 131E calculation framework to benchmark designs for the future Pristina Wastewater Treatment Plant in Kosovo.
This structured approach ensures that all critical aspects are considered, from initial load analysis and biological process design (including nitrification and denitrification) to the final design of the secondary clarifier and practical operational considerations.
The standard provides a range of recommended design values, including:
