Rain Gardens as Integral Parts of Urban Sewage Systems-a Case Study in Thessaloniki, Greece

In this paper, integration of rain gardens in sewer systems is investigated, by means of a case study, in Thessaloniki, Greece. The effect of location and size of rain gardens is examined, together with the quality of local sewer network. Our calculations have shown that existing infrastructure is insufficient and that construction of rain gardens could substantially mitigate the nuisance caused by inundation of streets and sidewalks during rain events.
