The order enables industries like Mangalore Refinery and Petrochemicals (MRPL) and Mangalore Special Economic Zone (SEZ) to draw water from AMR power dam built across the Nethravati at Shambhoor in Bantwal taluk.
The MRPL lifted six million gallons a day (MGD) and industries under SEZ lifted eight MGD from the Shambhoor dam, official sources said.
The water level in Thumbe dam had hit all time low over the last few weeks.
Water sufficient to pump adequate water to the city for about 15 days was now available from the dam, the release said.
