Whom to contact regarding drainage problem and local flash flood. Both DID and the appropriate local authority are responsible for drainage. The public may be at times rather confused. In general the local authority is responsible for the construction and maintenance of the local drainage system which mainly of trunk drains and secondary drains. DID is responsible for the rivers which may flow within and outside the local authority areas.
Floodings caused by choked drains and culverts fall under the responsibility of the local authority.
DID has PRO office in each state. DID also collects some information on water quality especially on the sediment load. Use of River reserve. In general DID does not encourage application to use our river reserves because we need the access any time for emergency repair works as well as for river maintenance. However, we may consider certain applications on a case by case basis.
