Rainage and drainage systems

Rainwater and drainage pipelines are needed in climatic zones where average precipitation exceeds evaporation. Therefore, stormwater drainage plays a very important role in water management. Rainwater and groundwater regulation and its impact on construction sites is a challenge for designers and builders in the whole world. Surface water and groundwater must be drained to extend the service life of roads, streets and car parks, railways and house foundations and to regulate quality as well as the humidity of agricultural land.
