* Diversion Scheme

Irrigation reservoirs and canals are widely used for drinking water supply now.
Minor irrigation schemes being carried out throughout the state includes
- Lift Irrigation Schemes,
- improvement of existing lakes and ponds, diversion schemes for natural streams,
- prevention of salinity intrusion in rivers, drainage works to paddy fields,
- construction of check dams, vented cross bars, sluices.
- flood damage control works including river training and eco restoration .
The department is responsible for protecting the Sea coast from beach erosion. This is achieved by protecting the coast by the construction sea wall, groynes etc. at selected areas.
Another important activity of this department is the Inland Navigation work to provide a state water way connecting Neeleswaram in the North to Kovalam in the South.
