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 ATV-DVWK Standards and Advisory Leaflets, as far as possible and practical to standardise the derivation of values for the dimensioning of drainage systems and municipal wastewater treatment plants as well as the symbols for dimensioning values.weiterlesen
