This dam on river Sank was constructed in the year 1917, in stone masonry in lime mortar. Foundations are resting on massive sand stone. It had breached in very first filling and was reconstructed by 1929.
To arrest the seepage and to consolidate the body of 915 M long dam, it was decided to drill and grout the entire length of dam and to provide 2 M wide grout curtain on u/s face of masonry dam. Thereafter the holes were drilled 6 M apart staggered in two rows 2 M apart. Wherever seepage was heavy, secondary holes for drilling and grouting were done. Average depth of grout curtain was 24 M. This treatment has reduced the seepage within permissible limit. After grouting was completed inclined release holes were done in the body of masonry dam to release the poor pressure, along a line about 15 feet d/s from the heel of the dam at 50 feet centre to centre.
In last so many years, due to ageing, dam had been leaking at number of points on downstream, Water had gushing out heavily at few places and at places, most of lime mortar had flushed out of the masonry joints. Before grouting operations, pointing in rich cement mortar was done on u/s and d/s face of dam.
