Sewerage problem in Dhaka City

Introduction

Dhaka, the capital of Bangladesh is one of the most densely populated cities of the South-Asian countries. Due to rapid urbanization process, the city is emerging as a mega-city and this trend generates numerous economic and social externalities. I want to work on this topic because this problem is related to our daily life, and we are the victim of this problem especially in the rainy season. Drains and cannels are stuck for several days and due to the drainage congestion Dhaka metropolitan area has experienced water logging for last couple of years. Even a little rain causes a serious problem for certain areas, so that parts of Dhaka are inundated for several days. It makes difficult to move for the passer by.

Solution which comes out will help us from this topic. To find out inherent causes of water logging in Dhaka City, a field survey as a questionnaire survey, informal interviews from the people living in different parts of Dhaka City.

PRESENT SITUATION

The capital city of Bangladesh has become one of the populous Mega City in the world, in recent year’s sewerage and water logging has become as a common problem of the city like water pollution, traffic congestion, air and noise pollution, solid waste disposal, black smoke etc.
Unplanned capital development activities and growth of habitation due to rapid population growth are causing encroachment on retention areas and natural drainage paths with little or no care of natural drainage system. Excessive rainfall, inadequate drainage sections, conventional drainage system with low capacity and gravity, natural siltation, absence of inlets and outlets, indefinite drainage outlets, lack of proper maintenance of existing drainage system, and over and above disposal of solid waste into the drains and drainage
