1.Partially treated sewage that is stored in a septic tank is commonly called as Septage. It includes liquids, solids (sludge), as well as fats, oils and grease (scum) that accumulate in septic tanks over a period of time.
2.Septage management includes the process of design of Septic Tanks and collection, safe treatment and disposal of septage.
3. A comprehensive program that regulates periodic septic tank cleaning, as well as septage transport, treatment, re-use and disposal is important in the context of our rapidly urbanizing economies.
4.Out of 15 Corporations (including Chennai), 121 Municipalities, 528 Town Panchayats and 12,525 Village Panchayats in the State, the UGSS is functioning in 12 Corporations (including chennai), 35 Municipalities and 3 Town Panchayats.
5.Till the uncovered areas of ULBs are brought under UGSS there is a need for feacal septage management for safe handling of the faecal sludge.
Need for Septage Management:
Comprehensive guidelines have been issued by the Government vide G.O. (Ms) No. 106 MA&WS Department, dated: 01.09.2014 to regularize and monitor the handling of faecal sludge by co-treating in the existing STPs and creation of dedicated Fecal Sludge Treatment Plants (FSTPs). The guidelines contemplated the following initiatives:-
1.Design and Construction of Septic Tanks.
2.Septic Tank Pumping & De-Sludging.
1.Treatment & Septage Disposal
2.Fees / Charges for Collection, Transportation and Treatment
3.Information, Education and Communication
Record-keeping and Reporting:
A cluster approach has been adopted to ensure optimum utilisation of Sewage Treatment Plants. 41 Clusters have been identified and grouped in such a way that all collection points are situated approximately at a radius of 5-10 km from the designated Sewage Treatment Plants (STP), of which, 21 Clusters have been firmed up. Urban and Rural Local Bodies situated in and around these clusters are also decanting the faecal sludge in these Sewage Treatment Plants. Clustering of adjacent Urban and Rural Local Bodies in and around the balance STPs is being explored.
Enumeration of existing Septic Tanks and establishment of decanting facilities in the functioning STPs are in progress. So far, in Corporations and Municipalities, Sewage is being collected from septic tanks, carried through lorries registered with ULBs are permitted to decant into nearby Sewage treatment plants and get treated there.
46 number of Feacal Sludge treatment plant has been sanctioned and the works are completed in 9 ULBs and others are in various stages of implementation.
