DWA-A 131E - Dimensioning of Single-stage Activated Sludge Plants - June 2016 (translation May 2022)
Using the dimensioning values recommended in this Standard, the minimum requirements for municipal wastewater with single-stage activated sludge plants can be met or bettered at national level. In contrast to earlier editions, in which the dimensioning procedure for nitrifying and denitrifying activated sludge plants was based on the measured BOD5 load, the design is now based exclusively on the COD load.

Fit in wastewater technology? Revised Edition June 2021
This workbook was written by professionals for professionals. It is not a classic textbook. Achim Höcherl, an experienced trainer and expert, developed „Fit in Wastewater Technology“ based on his idea of the Modular Wastewater Training System. The aim of the tasks is - as with the Modular Training System - to achieve holistic learning. That means learning with all senses - with head, heart and hand.

DWA-Topics T4/2016 - Design of wastewater treatment plants in hot and cold climates (EXPOVAL) - corrected version May 2019
The design of wastewater and sludge treatment plants under deviating wastewater and climatic conditions in other countries requires an amendment of existing design rules compliant to the DWA Set of Rules, which have been primarily developed for Central European conditions. This concerns, for example, the consideration of high or low wastewater temperatures, increased salt content or special discharge requirements.

Standard DWA-A 262 - Principles for Dimensioning, Construction and Operation of Wastewater Treatment Plants with Planted and Unplanted Filters for Treatment of Domestic and Municipal Wastewater - November 2017
This Standard sets out a common basis for the design, construction, and operation of planted and unplanted filters for biological treatment of municipal wastewater. Wastewater treatment with planted and unplanted filters is characterized by a simple structural design, a simple mode of operation, a low production of biomass and secondary sludge, a low use of external energy, and a high treatment efficiency, even for treatment systems with a small number of sewer connections.

DWA-A 161E - Static calculation of Jacking Pipes - March 2014, corrected version March 2021
This standard applies to the structural calculation of pipes with a circular cross-section which are installed according to the pipe jacking method in a straight or bending direction in non-cohesive or cohesive soils (loose soils as according to DIN 18319) with static force in accordance with Standard DWA-A 125/DVGW GW 304. For jacking in solid rock, either wholly or in part, there is no standard solution in this regard, instead, special considerations are to be made; for example application of smaller bearing angles and earth load over the pipe crest.
