Coimbatore Corporation has proposed to construct a sewage treatment plant (STP) to treat wastewater flowing through a natural drain that passes through the premises of Coimbatore International Airport.
On the southern side of the airport, a section of the compound wall is fitted with iron grills to allow the flow of water from a natural drain that enters from the north after crossing Avinashi Road. However, with sewage mixing into the channel, plastic and solid waste accumulate on the grills, blocking the flow and letting only water pass through. The drain then turns east from the airport, passes through Kurumbapalayam and ends at Kolathur tank.
