DWA-M 1060E - IT-Security (8/2017)

The Guideline DWA-M 1060E is published in October 2018. The translation is based on the German edition from August 2017.Operators of water supply and wastewater disposal installations shall have at their disposal high-Performance equipment, sufficiently qualified staff and robust quality assurance measures, because they have a paramount importance for the functioning of the community. As a result,... Learn More

DWA-A 199-1 - Operating Instructions (11/2011)

Operators of wastewater facilities shall establish service and operating instructions tailored to their respective circumstances in order to adhere to the requirements especially of § 57 of the German Water Resources Management Law (WHG) and in order to meet the minimum requirements of the self-inspection or self-monitoring ordinances of Germany's federal states. Since the regulatory content of t... Learn More

DWA-Topics - Anthropogenic Pollutants (5/2008)

Modern methods for water analysis make it possible to detect small concentrations of anthropogenic trace pollutants, such as e. g. pharmaceuticals and substances exhibiting hormone activity. There is no doubt that pharmaceuticals are present in our water bodies and their presence has been proven by various examples. However, natural and technical barriers guarantee that for the time being residues... Learn More

Wastewaterengineering - 2007

An informative, comprehensive, and up-to-date revision guide for the occupational training in wastewater engineering offering numerous tasks and solutions in order to prepare trainees in the field of wastewater engineering for the technician and master technician examinations. 550 questions and tasks with the respective solutions – an ideal preparation to successfully pass the state examinations...

DWA-M 149-4 - geographical techniques (7/2008)

The Advisory Leaflet makes recommendations and provides information on measuring techniques, by means of which bedding defects and cavities can be detected in the surrounding of earth-buried pipelines. It describes possible applications and application limits of the measurement methods ground-penetrating radar (GPR), geoelectricity as well as seismic technology.Additionally, research and developme...

DWA-A 116-2E - Pressure Sewerage System (5/2007)

Pressure drainage is a special drainage process which, under certain circumstances, is significantly more economic than a gravity sewer system. Compared with other drainage processes the investments can be considerably lower. In cost-comparison calculations all follow-on costs for depreciation, rate of interest, operation and preventative maintenance are to be incorporated. The Standard, along wit... Learn More

DWA-A 116-1E - Vacuum Sewerage Systems (3/2005)

This Standard is directed in particular to consulting engineers, system suppliers, regulators, contractors and operators. The objective of the Standard is to help the designing engineer to recognise and creatively use the latitude given in EN 1091 and facilitate the application of EN 1091. Part 1 of the Standard provides information about vacuum sewerage systems outside buildings and specifies req... Learn More

DWA-M 381E - Sludge Thickening (10/2007)

Thickening of sewage sludge is one of the most important basic treatment steps of the entire sludge treatment process. For decades thickening of sewage sludge has been accomplished by using either gravity settling in thickeners or in a flotation unit or by mechanical thickening. Flotation and mechanical thickening processes are almost solely used for the thickening of waste activated sludge. In 19... Learn More

DWA-Topics - Downstream Fishways (7/2005)

This book completes DVWK M 232 „Fish Passes - Design, Dimensions and Monitoring” and presents fish protection and downstream fishways which are available national and international. It summarises national and international state of knowledge and is perceived as a tool to fulfil the EC Water Framework Directive as well as demands of animal and wildlife protection. As this duty requires hy... Learn More

ATV-DVWK-A 198 - Standardisation (4/2003)

This Standard is concerned with the definition, collection, evaluation and examination of data as well as with the subsequent derivation of dimensioning values based on these for wastewater treatment plants and drainage systems. Forecast data for various time horizons can subsequently be derived from measured data. With this Standard the objective is pursued, globally for all DWA Standards and Adv... Learn More
