Abstract

In the Czech Republic valid legislation (268/2009), (501/2006) demands a reduction of rainwater outflow from real estates. At present in the Czech Republic regulations for rainwater harvesting and infiltration are finalizing. The Czech standard CSN 75 9010 for rainwater soakaways is in completing process and there is also ready the Technical Tool of Czech chamber of chartered engineers and technicians (TP 1.20) about rainwater conservation management. This paper shows principles of design of rainwater harvesting systems and rainwater soakaways based on above regulations. The paper is also coupled with an example of overground soakaway dimensioning.
