DWA-A 100E - Urban Drainage (12/2006)

As a framework of action concerning the detailed regulations for urban drainage, this Standard is intended to 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-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 118E - Hydraulic Dimensioning (3/2012)

This DWA Standard concerns the dimensioning and verification of drain and sewer systems, which are mainly operated as gravity systems and which serve for the discharge of domestic and industrial wastewater, surface water and combined wastewater. It contains guidance for determining the quantities of wastewater to be discharged, taking into account both the replanning and the recalculation of exist... Learn More

DWA-A 125E - Pipe Jacking (12/2008)

This Standard deals with the underground installation of pre-fabricated pipes with different geometry of the cross-section. During the installation, a cavity is created in the ground by displacing, ramming, drilling, pressing or other installation. The pipes are pulled, pushed or pressed into this cavity or existing sewers or pipelines are passed and/or replaced. For shield drives (e. g. segment l... Learn More

ATV-DVWK-A 134 - Pumping Stations (6/2000)

The paperback is out of stock, but the e-book is still available. The pumping station, with the discharge of wastewater, has its particular significance in that, through the avoidance of too deep a position, it can improve the economic efficiency of a drainage system. It is extensively independent of topographical conditions and makes it possible to feed effluents into receiving waters and sewers... Learn More

DWA-A 138E - Facilities for Percipitation (4/2005)

The Standard ATV-A-138 dated January 1990 has been revised and increased it considerably in the area of application. In addition the symbols used have been matched to those in Standard ATV-DVWK-A 198 published in April 2003. The recording of all surfaces providing runoff in one standard with notes on special regulations enables a comparable taking into account of the demands of soil and water poll... Learn More

DWA-M 144-3E - ZTV Hose Liner Process (11/2012)

Damaged drains and sewers represent a hazard to the environment, especially the groundwater and soil. Various experiences have been made in rehabilitating damage using renovation processes with locally cured hose liners. Part 3 of the Advisory Guideline DWA-M 144 supplies supplementary harmonised, standardised technical contract conditions (ZTV) for this process. The supplementary technical contra... Learn More

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...
