The Municipal Administration and Water Supply Department is the principal agency in Tamil Nadu overseeing urban water supply and sanitation. Urban Local Bodies enforceonsite sanitation systems (design and build) based on the State-level regulations. The service of collection and conveyance of FS is largely provided by an established market of private operators with minimal regulation from the State through a Government order issued for a Standard Licensing Agreement (SLA). The SLA mandates desludging operators to adopt proper desludging and disposal practices, and safeguard the health and safety of their employees.
The implementation of the State Investment Plan for scaling of treatment facilities across the State is driven by the Commissionerate of Municipal Administration (CMA) which is responsible for municipal corporations and municipalities, and the Directorate of Town Panchayat (DTP) which oversees town panchayats. Government orders have been issued for i) construction of treatment facilities and ii) Memorandum of Understanding between the ULB clusters that govern the co-treatment process and the use of upcoming shared treatment facilities. The treatment of fecal sludge and its disposal is regulated by the standards set by the Pollution Control Board. More details on systems and procedures for FSM in Tamil Nadu can be found here
