The dam is located near the border of Maharashtra and Karnataka and necessitated the relocation of several villages in the area.

"There has been no official ribbon-cutting function, no fanfare and no announcements, but the Rs 15 billion Tilari dam, a joint venture between Goa and Maharashtra, is now complete.

Tillari supplies 7.5 million litres per day to the Chandel water treatment plant in Pernem and 90 million litres per day to the Assonora water treatment plant in Bardez.

Presently the right bank main canal supplies 7.5 million imperial gallons (34,000 m3) per day to Pernem and the left bank main canal supplies 18.5 million imperial gallons (84,000 m3) per day to Bicholim.

But the original project provision is for the supply of 52 million imperial gallons (240,000 m3) per day from the year 2011 onwards.
