Objective of Drainage Plan considers present functions of main and secondary drains and natural streams within the Tungipara Pourashava. Secondly, to find out level of encroachment over drainage reservations responsible for flooding, water logging of neighborhoods during heavy rains. Thirdly, to find out, present roadside drains including capacities and collected gradients. Planned development of Pourashava very much desirable. Drainage Master Plan ensures operation and maintenance of the present facilities including new proposal for future. For this, short and long term Project Improvement Plan with involving area necessitates to ensure proper drainage of the Pourashava.

In implementing various infrastructural developments, gives less priority on drainage and normally considers last or final steps of development. Such scenario particularly true for Bangladesh. Although different types of drainage infrastructures among others by far the heaviest impact 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 allocates fund. Mostly of those funds spend on buildings, roads and other more visible infrastructures. Drainage comes as the last item of development. By the time, drainage development begins to start. It appears shortage of fund. Consequently as a matter of policy-do little or do-nothing situation appears and as eyewash very little is done for drainage development. In case of urban development, if drainage not maximizes priority, sufferings of the inhabitants will continuously increase with the passage of time.

Drainage facilities construction for urbanization starts with drain. Drain classifies as Plot drains, Block drains, Tertiary drains, Secondary drains and Primary drains. Other natural drainage infrastructure identifies as 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. It appears from the physical feature survey. Environmental survey follows a pro to-type questionnaire.
