The world is turning in to a concrete jungle at such a frantic pace and in such a compact fashion that it almost is getting impossible to restore the ground water levels each year. The water seems to have absolutely no place to seep through and that is the reason why all the rain is getting washed up in to the gutter of the ocean. When there is no rain, it is a drought and when there is rain it turns in to flood crisis. It just goes to show what our messing with planet can do.
An example of how we can alter that situation with intelligent use and apt changes of technology is shown by this amazing case of rainwater harvesting system. A great example of rainwater harvesting can be found at the Langston Brown Community Center and High School in Arlington, Virginia. The community center has two 24-foot-tall 11,000-gallon cisterns that store rainwater. The tank at the front of the school is covered with panels, and fits seamlessly into the overall design of the building.
The building captures 280,000 gallons of water a year. Regrettably, the rainwater is only used for onsite irrigation, sidewalk washing, and other non-potable uses. However, the center does have waterless urinals which result in a 23% reduction in potable water use. Nearby in Maryland, the Philip Merrill building captures even more rainwater — 402,461 gallons a year — the rain provides almost all the water used in the building. The whole system tells you how sensible use of technology and commonsense can save us from an impending doom and imminent water crisis!
