Common Observed Problems in DRIP Dams

Seepage boils & leakage d/s of earth dams; Deformity & erosion of u/s and d/s slopes,

erosion of abutments and settlement &cracks along dam crests;

Excessive seepage through masonry/conc.dams;

Cracks and pitting in spillways and outlet gatestructures, erosion of energy dissipationsystems;

Deficiencies in gates and hoisting system; Malfunctioning of dam monitoring

instruments. Under-designed spillways.

Time Extension

13

• Time extension of DRIP was requested during 14th TC meetingat Cochin on account of late work awarded.

• 2 Year extension for all IA’s was agreed during 14th TC meetingto accommodate projects with long construction period.

• MoWR,RD&GR concurred the proposal of time extension bytwo year in Nov 2016 & directed CWC to submit the proposalto DEA/World Bank

• CWC has submitted proposal of time extension to DEA.

Cost Revision

14

• Initial cost of DRIP Dams involved Rs. 2100 Cr. with Rs. 1610 Cr.as Component -1 (i.e. rehabilitation cost).

• The cost of Rehabilitation works for 214 Dam Projects for whichPSTs have been approved by World Bank is Rs. 2636 Cr.

• Overall cost of DRIP for the approved Dam Projects is nowrevised to Rs. 3100 Cr.

• All IA’s / SPMU’s were asked to obtain administrative &financial concurrence from their respective departments totake up the revised cost issue with the GoI & WB.
