Study on Existing Drainage and Water Logging Problem at HSTU Campus Area in Dinajpur, Bangladesh

Abstract

In rapidly growing urban regions of Bangladesh, several environmental hazards are now surfacing as main obstructing factors in the development activities. Specially, in the cases where existing drainage systems are available, new planning and updating process is often overlooked. To understand the drainage problems in Hajee Mohammad Danesh Science and Technology University (HSTU) area, the campus area was examined for the existing surface drainage conditions. By adopting some generalized sampling method, field survey was conducted and the study area was also surveyed with a total of 100 respondents living within it. 42% of the residents told that the current drain numbers are insufficient, 34% said solid wastes clogged the drain and the rest of them said that both of these are responsible for the drainage system's underperformance. The various data were collected and analyzed providing some key observations, such as, there was a lack of well-planned drainage system, along with complications related to insufficient outfalls and maintenance issues. The poor drainage condition causes inundation of unsuspected areas that results in early pavement deterioration and also bring discomfort to the residents by hindering their day-to-day activities. For some drains with connection problems, alternative routes with new connections among the existing drains were suggested. Construction of new outfalls with proper outlets and branch drains with good connections to main drains would help to minimize rainwater runoff in drains. For future improvement, some provisions such as sand trap and bar screen were recommended as a solution of excessive sludge problems.
