A simplified dimensioning method for high-efficiency retention tanks

Abstract

The article presents the results of research on the development of a simplified dimensioning method for sewage retention tanks equipped with a high-efficiency hydraulic system. The need to develop a new method is associated with the outdated rainfall model by Błaszczyk, which is the most popular model in Poland. According to the research made by numerous scientific centres, this model underrates the values of the maximum intensity of critical rains. As a consequence, its use affects the design of sewage systems and related facilities with insufficient hydraulic capacity.
