WHERE THE WATER GOES AFTER HEAVY RAIN? It doesn’t rain very often in the desert, but when it does, we often lose the opportunity to capture the rain water. Comparing these two types of water cycle- in natural water cycle, half of the water could be percolated into the soil, only 10% will be the surface runoff; however, in urban water cycle, 55% of water will be surface runoff, and only 10% of the water could be percolated into the soil. City is losing the ability to capturing the rain water. So, where these water go? In south of Tempe , there is a large artificial lake called Kiwanis park lake, acting as a water retention and receiving the rain water from the communities in the east. Storm water runoff in our auto-dominated communities is toxic because it concentrates hydrocarbon residues from household and lawn care chemicals, oil, gasoline, brake fluid, asphaltic products in roads and roofs, and heavy metals, which are ultimately deposited into our watersheds. LID is a good tool to clean the water and make design visible and useful.
