TIRUCHIRAPPALLI (Tamil Nadu): Rapid expansion under the Atal Mission for Rejuvenation and Urban Transformation (AMRUT) scheme has pushed the 58 MLD Sewage Treatment Plant (STP) at Panjappur to its absolute limit, triggering operational bottlenecks for the Tiruchirappalli City Municipal Corporation.
In a post on X, the Corporation said the existing 58 MLD STP at Panjappur had reached its full designed capacity following the expansion of the Underground Sewerage System (UGSS) under AMRUT.

Immediate desilting and clearance works are underway to restore normal treatment at the facility, according to the Corporation.
