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.

Activated Sludge Expert with Aeration
The combined version includes both the calculation to DWA-A 131 (June 2016) for the design and recalculation of single-stage activated sludge plants as well as additionally the design and recalculation of pressurized aeration systems according to DWA-M 229-1.

DWA-Topics - Non-Potable Water Reuse - Development, Technologies and International Framework for Agricultural, Urban and Industrial Uses - June 2019
This report is intended to provide general guidance for water utilities, consulting engineers and regulatory agencies for planning and expanding non-potable water reuse as an alternative freshwater supply, in particular for agricultural irrigation, urban landscape irrigation and other urban uses, and industrial practices.

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.

Standard DWA-A 216E - Energy Check and Energy Analysis - Instruments to Optimise the Energy Usage of Wastewater Systems - December 2015
This Standard introduces the energy check and energy analysis as instruments for energy optimisation of wastewater systems and formulates requirements for their execution. The scope of application covers wastewater treatment plants and wastewater collecting.
