is a simple and reliable possibility for decentralized rainwater management. Especially in the context of drainage on properties, trenches and swales are used for decades. After 1990, networked systems, such as “swale-trench-systems”, were more commonly used for reducing the

Development and Environment. The stormwater concept includes different stormwater management elements throughout the B-plan area. These include swales, swale-trench systems, trench systems, extensive and intensive green roofs and an additional storage sewer for areas which cannot

a breakdown of a boundary wall. Moreover heavy rainfall leads to erosion and instability of the hillslope. For resolving the drainage problems a swale-trench system has been suggested parallel to the hillslope and completed with custom throttle pipes in the boundary wall (so-called “Llorones”).

evaporation and retention systems. Here you can download the actual demo-version of the long term simulation software for infiltration systems like swale-trench systems, ponds, cisterns and other storm water management systems. Also centralised retention measures are included. The program

As a result of these limiting factors, an innovative storm water system was planned and consisted of channeling the runoff into a network of swales and retention trenches implemented in privet and public areas along with a semi-centralized infiltration system. The newly proposed measures

space areas, the optimal solution of the project necessitated to drain stormwater into underground chambers connected by an overflow throttle to a swale that, in return, will promote excess runoff infiltration into the soil.

cisterns. In the case of cistern overflow, the excess water volume was diverted along with the road runoff towards a series of cascading channels, swales and retention trenches. The advantages of the proposed measures are: Reduction of water pollution Reduction of flooding risk from streams
