荷兰尤斯腾塑料制品公司开发出一种半开式地砖,可以防止多雨季节里过多的雨水通过下水道系统流入河道。这种新型地面用材称为尤斯腾G.S.地砖,使用它可以避免不断加高堤坝之苦,并有助于维持饮用水供应所依赖的地下水位。 Eustatm Plastics, a Dutch company, has developed a semi-open floor tile that prevents excessive rain from flowing through the sewer system into the river during the rainy season. This new type of floor material is called Euston G.S. Floor Tiles, which can be used to avoid the constant increase of levees and help maintain the groundwater level on which drinking water supplies depend.
