Present urbanization happening in these cities create an imbalance between generated urban runoff volume and effective drainage capacity. For the survival of these, it is vital in enhancing the efficiency of an urban drainage system. However, it is a complicated task due to the accumulation of solid waste in drainage channels. These drainage systems are super sensitive to some external factors caused by their immediate surroundings. This study found out the impact of the urban form, population agglomeration, floating population, imminent prone areas of urban sprawl and waste disposing patterns of settlers can be highly influenced to the efficiency of a storm drainage system. Hence, Geographical Information System based computational techniques and weighted fussy sets are being used to track the attention need areas of the system. These particular zones to be treated through the design of "Smart Storm Drainage Unit". By this, it is expected to maintain a clear drainage channel for transportation of surface runoff all the time. Thus, by Smart Storm Drainage will be fixed into the breakdown areas or highly sensitive areas of a drainage system. This paper discusses the impact of surrounding urban area to the breakdown of the drainage system and fixates the problem by bypassing “Smart Storm Drainage Unit”.

Solid waste accumulates in drainage systems, heavy rainfall, increased runoff volume and stagnation of runoff flow could collectively lead to sudden flash floods in compact cities. Events leading up to a flash flood attack in a city show a marked similarity to the cascade of events leading to a heart attack. Accumulation of fat in coronary arteries restricts the blood flow to the cardiac tissue. When the arterial occlusion is beyond a critical level, myocardial
death occurs. This condition is commonly known as a “heart attack.” The clinical solution for this is known as coronary artery bypass grafting. As such, this paper urged for a novel technical solution which, could be introduced to reroute stagnated water flow in a clogged drain with the objective of treating the socioeconomic impact of “Blocked Drains Syndrome.”
