Objective of Drainage Plan is to find out present functions of main and secondary drains and natural streams within the Bakerganj Pourashava. Secondly, level of encroachment over drainage reservations responsible for flooding, water-logging of neighbourhoods during heavy rains also analyzes. Thirdly, information collects on existing roadside drains including capacities and collected gradients. Since planned development of Pourashava is very much desirable, Drainage Master Plan is necessary to ensure operation and maintenance of the present facilities including new proposal for future. For this, short and long term project improvement plan, area-based drainage master plan is necessary to ensure proper drainage of the Pourashava.

Methodology and Approach to Planning

In implementing infrastructural developments, drainage is generally given less priority and normally considers as last or final steps of development. Such scenario particularly true for Bangladesh. Although different types of drainage infrastructures, among others by far the heaviest impacts on physical infrastructure network. As a result, physical environment, health, hygiene and standard of living suffer seriously. In development projects, Government, Semi-government and Public sector allocate funds. Those funds mostly spends on buildings, roads and other more visible infrastructures, drainage comes as the last item of development. By the time, drainage development starts. Appears shortage of fund, consequently as a matter of policy-do little or do-nothing situation appears. As eyewash very little performs for drainage development. In case of urban development, if drainage not emphasizes, sufferings of the inhabitants will continuously increase with the passage of time.

Drainage development for urbanization starts with drain. Drains are classified as Plot drains, Block drains, Tertiary drains, Secondary drains and Primary drains. Other natural drainage infrastructure is lowland, outfall areas, khals and rivers. Man-made drains are Plot, Block, Tertiary, Secondary and Primary drains and others are natural drainage infrastructures. In planning for drainage network, care has given on road network in terms of conflict of drainage and waterways with roads. Drainage and environmental survey follows a proto-type questionnaire.
