Measures to promote stormwater infiltration

In Japan, infiltration facilities have been constructed systematically and enthusiastically at many construction sites, such as, roads, parks, houses, schools, rivers, and sewers. In this study, methods for spreading stormwater infiltration are proposed by making use of these experiments and achievements of stormwater infiltration. At first, the problems concerning stormwater infiltration are introduced. Secondly, measures for spreading stormwater infiltration are considered, and in fact, stormwater infiltration technology is spread by these methods.
