Could porous pavements be a part of the urban water solution?

随着澳大利亚的用水需求接近，有时甚至超过可持续性的极限，迫切需要寻找替代水源。与此同时，城市雨水污染仍然是一个主要的环境威胁。由于空间限制，这些问题在城市地区尤其困难。该项目将测试和改进多孔路面技术，这将有助于解决“城市水问题”。用多孔路面取代不透水的地区将使城市雨水得到处理和收集以供再利用。水路将免受污染，产生的大量城市雨水（类似于澳大利亚的管网供水总量）可以被收集以维持城市的发展。

With water demand in Australia approaching, and sometimes exceeding, limits of sustainability, there is a pressing need to find alternative water sources. At the same time, urban stormwater pollution remains a major environmental threat. These problems are particularly difficult in urban areas, due to space constraints. This project will test and refine porous pavement technology, which could help solve the 'urban water problem'. Replacing impervious areas with porous pavements will allow urban stormwater to be treated and harvested for re-use. Waterways will be protected from pollution, and the vast quantity of urban stormwater generated (similar to the total reticulated water supplied in Australia) can be harvested to sustain cities.
