Urban Storm Water Management through Artificial Recharge for Smart Cities

Abstract

Abstract
The storm water during rainy season causes drainage problem and often roads are damaged by rainfall runoff. This problem is serious in big cities and number of industries, where most of the open area is covered by roads or some concrete structures without proper drainage. The water on roads during rains remains stagnant for hours together due to poor storm water management and results into erosion of roads. Our major cities and industrial areas are facing water crisis due to over exploitation and declining water levels. The paper deals with the solution of managing storm water on roads/paved area in industries and channelizing the same to ground water system in hygienic manner based on hydroinformatics in terms of rainfall pattern, rainfall intensity and recharge capacity of sub-surface hydrogeological formations (CGWB). In this project, infiltration recharge systems through soil aquifer treatment system (SAT) technology may be adopted (Bouwer Herman, USA). The technology
is used innovatively through the vadose zone which purifies most of road impurities before meeting ground water. The recharge structures should be provided with inverted filter and chemical ingredients like charcoal to negate effect of oil and grease and the impurities likely to be present on busy road and paved areas, as further precautionary measures. These ingredients are in addition to usual filter media. The monitoring well should also be made to evaluate long term benefit of the project in terms of improvement of quality of water and water levels. The concept would not only help in controlling devastating effects of storm water but would also improve quality of water and increase life of roads due to minimum damage to road by runoff water and reduction in cost on maintenance and repair of the road. The storm water management and artificial recharge to ground water is sustainable in long term, if periodical maintenance like replacement of silt from storage chamber and change of upper
coarse sand and chemical ingredients in filtration chamber before monsoon. The main strength of the concept is in its replication as it can be adopted on all roads of urban sector after taking it as pilot project for smart cities to be developed.
