DWA-M 386E - Thermal Treatment (12/2011)
Thermal treatment of sewage sludge is in regard to quantity the most important disposal route in Germany. It is an important option for a safe, economically efficient and environmentally sound sludge disposal. Since the late 1980ies, the percentage of sludges which are treated thermally has risen from about 12 % to more than 50 %. Almost half of these sludge quantities are treated in mono-i...

DWA-M 387 - Thermal Treatment (5/2012)
The objective of the Advisory Guideline DWA-M 387 is to give fundamental information for the technical realisation and operation of plants for the co-incineration of sewage sludges in coal power plants. Based on fuel characteristics of sewage sludge, the effects of co-incineration on various fi ring systems for brown and black coal, on fl ue gas purifi cation and on incineration residues are dealt...

ATV-DVWK-M 503 - Tailings Impoundments (12/2001)
The focus of this advisory leaflet is thus on the plant safety from a constructional and hydraulic engineering point of view. It nevertheless seeks to devote adequate space to the environmental aspects of such facilities which are receiving increasing recognition.The advisory leaflet the contents of which are primarily keyed to existing plants, whether still in service of decommissioned, will prov...

DWA-M 507-1E - Levees Along Watercourses (12/2011)
The leaflet’s span of application was extended from ‘Levees’ to ‘Levees built along watercourses: Introduced to this end was a classification system that categorises the levees by height and inherent risk potential, therewith covering a bandwidth of vital aspects of the involved design and engineering work.Described are the specific hydraulic design parameters, the documentary evidence to ...

DWA-M 512-1E - Sealing Systems (2/2012)
It covers surface and internal sealing systems for soil structures in hydraulic engineering as they are applied in practice. Described are surface and internal sealing systems used in earthwork structures, including asphalt and concrete sealing systems, geosynthetic clay liners, mineral sealings, geomembranes, fully grouted riprap, sheet pile walls and internal sealing systems made of hydraulicall...

DWA-M 514 - Dam Surveilance (7/2011)
The principles of dam monitoring are dealt with in detail, with regard to both the technical and the human side of the topic, supplemented by issues like structural assessment, sensor technology, automation, data management, and others. Included are generally valid and noteworthy criteria and points for the most commonly applied measuring procedures and systems, with special focus on the structu... Mehr erfahren
DWA-M 803E- Cost Structures (11/2006)
The Advisory Leaflet provides the preconditions for the collection of investment costs and operating costs as well as any relevant technical information about the lifetime of the project in a standardized and constant form. In a first step (Advisory Leaflet version of 3/2002), a constant cost structure was developed which initially focussed on recording the investment costs alone. The structure co... Mehr erfahren
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,... Mehr erfahren
DWA-Topics - Wastewater Treatment plants (10/2016)
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... Mehr erfahren
