Sambandar, an 8th-century Tamil Saivite saint poet, venerated Uchinathar in ten verses in Tevaram, compiled as the First Tirumurai. As the temple is revered in Tevaram, it is classified as Paadal Petra Sthalam, one of the 276 temples that find mention in the Saiva canon. The temple is counted as the third in the series of the temples on the northern bank of river Cauvery.

The temple priests perform the puja (rituals) during festivals and on a daily basis. The temple rituals are performed three times a day; Kalasanthi at 8:00 a.m., Uchikalam at 12:00 a.m. and Sayarakshai at 6:00 p.m. Each ritual comprises four steps: abhisheka (sacred bath), alangaram (decoration), naivethanam (food offering) and deepa aradanai (waving of lamps) for Uchinathar and Uchinayagi.
There are weekly rituals like somavaram (Monday) and sukravaram (Friday), fortnightly rituals like pradosham, and monthly festivals like amavasai (new moon day), kiruthigai, pournami (full moon day) and sathurthi. Vaikasi Visagam during the Tamil month of Vaikasi (May - June) is the most important festival of the temple. Navratri during Purattasi and Karthikai somavaram are other festivals celebrated in the temple.
