The Noyyal Orathuppalayam Dam and Reservoir, also called Orathuppalayam Dam, is located on the Noyyal River between Chennimalai and Kangayam in Tirupur District, Tamil Nadu, South India.

The farmers, who depended on the dam and river for irrigation, stopped the farm activity in their land.

Due to the sad conversion of Irrigation dam to Effluent tank, the people living down river in the Tirupur, Karur District are negatively affected.

Kodumanal, famous archaeological site containing Roman coins, potteries and megalithic tombs is severely affected by effluent.

The dam is a major concern for environmentalists because of its polluted waters.
