The Chithrai festival and the vaigai river are both associated with Madurai. Meenakshi from madurai will return home to bathe in the beautiful vaigai river and witness the goddess's wedding. The Kallazhagar vaigai river Descent is regarded as the Chithrai Festival's apex. Visitors to the Kallazhagar landing event will camp along the river's edge and partake in the festivities. They used to sit on the riverbank and pay their respects while swimming. As a result, the people of South tamil Nadu revere the vaigai river as a sacred river comparable to the Ganges. The riverbanks are busy during the Chithrai festival since the vaigai river used to flow all year.
Floods currently only happen during the monsoon season, particularly during the northeast monsoon. The vaigai river is dry at other times. Water used to flow naturally to the Chithrai celebration; now, water is dispersed at the Vaigai Dam to flow down the Kallazhagar River, which is a shame. The river was redirected to the kerala data-border due to the drought, and there was a dearth of rainfall in the catchment areas.
In this circumstance, sewage, private effluents, medical effluents, and building effluents discharged into the Corporation area have entirely polluted the vaigai river, much like the Koovam River, over the last quarter-century. The Alwarpuram vaigai river, which feeds into the Kallazhagar River, mixes with the entire sewage of the city during the Chithrai festival. Only during festival seasons can the company find a temporary solution.
