Statics Expert, Module Rehabilitation

This calculation module describes the verification of existing pipe conditions I-III by means of the Finite Elements Method (FEM) according to second order theory and prescribes a partial safety concept. You can calculate all necessary load combinations within one calculation process including interaction in existing pipe condition III for circular profiles. Egg-shaped and circular liners ...

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 116-2E - 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-A 161E - Static calculation (3/2014)

The standard was published in May 2018, based on the German edition of March 2014 in the corrected version of October 2017. 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 ...

DWA-M 180E - Real Time Control (12/2005)

The Advisory Leaflet introduces the basic aspects of real time control to potential users and presents a sound level of knowledge to those planners, operators and administrations involved in the development of real time control systems. It aims to achieve the use of real time control as a potential alternative on a regular basis in future planning of drainage schemes. This includes simple local co... Learn More
