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... Mehr erfahren
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... Mehr erfahren
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 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... Mehr erfahren
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... Mehr erfahren
