Swachh Bharat Mission: Liquid waste management covers 5.63 lakh villages
Liquid waste management infrastructure under the Swachh Bharat Mission (Grameen) now covers 5.63 lakh villages
The programme is expanding beyond individual/community toilet access to infrastructure that manages household and community wastewater
Villages are adopting decentralised systems designed to treat and reuse grey water and prevent open discharge of wastewater
The expansion reflects the shift of the mission's rural phase from an Open Defecation Free (ODF) focus to a broader "ODF Plus" sanitation standard
Swachh Bharat Mission (Grameen) Phase II and the ODF Plus Framework
SBM(G) Phase II is the second phase of India's flagship rural sanitation programme, shifting the mission's objective from achieving Open Defecation Free (ODF) status to sustaining it while adding comprehensive solid and liquid waste management (SLWM) infrastructure — together termed "ODF Plus."
Key Details
- SBM(G) Phase II was approved by the Union Cabinet in February 2020, to be implemented in mission mode from 2020-21, with the implementation period extended through 2024-25 and further to 2026-27
- Total outlay for Phase II: about ₹1,40,881 crore, funded through a mix of direct budgetary allocation from the Department of Drinking Water and Sanitation (about ₹52,497 crore) and convergence with 15th Finance Commission grants, MGNREGS funds, and revenue-generation/PPP models for waste management
- "ODF Plus" villages are those that sustain ODF status while also having functional solid and/or liquid waste management systems; "ODF Plus Model" villages meet the highest standard, with both visual cleanliness and full SLWM coverage
- SBM(G) was originally launched on 2 October 2014 (Phase I), focused primarily on eliminating open defecation through toilet construction
The 5.63 lakh village figure for liquid waste management reflects the maturing of SBM(G) from Phase I's toilet-access focus into Phase II's SLWM mandate, marking rural India's shift toward decentralised wastewater management as a distinct sanitation deliverable.
Solid and Liquid Waste Management (SLWM) — Technical Models
SLWM under SBM(G) is delivered mainly through low-cost, decentralised, gram panchayat-level infrastructure rather than centralised sewage treatment, given the dispersed nature of rural habitations.
Key Details
- Common liquid waste management technologies promoted under the mission include soak pits, leach pits, and "magic pits" (small-scale decentralised infiltration systems) for household grey water, and community-level Decentralised Wastewater Treatment Systems (DEWATS)/waste stabilisation ponds for larger volumes
- Faecal Sludge and Septage Management (FSSM) is treated as a related but distinct component, dealing with emptying and safe treatment of septic tank/pit sludge, guided by the National FSSM Policy framework
- Plastic Waste Management units and Material Recovery Facilities are the parallel component for solid waste under ODF Plus
- Implementation is driven at the Gram Panchayat level with technical support from state Rural Water and Sanitation departments and the Ministry of Jal Shakti's Department of Drinking Water and Sanitation
The reported expansion to 5.63 lakh villages signals village-level adoption of these decentralised liquid waste technologies rather than any large centralised sewage network — a distinction relevant for MCQs contrasting urban (AMRUT/centralised STP-based) versus rural (SBM(G)/decentralised) wastewater management models.
Constitutional and Institutional Basis — Panchayati Raj and Public Health
Rural sanitation delivery in India operates through the constitutionally empowered three-tier Panchayati Raj system, linking SBM(G) implementation to the 73rd Constitutional Amendment.
Key Details
- The 73rd Constitutional Amendment Act, 1992 inserted Part IX and the Eleventh Schedule into the Constitution, which lists "health and sanitation" (entry 23) and "drinking water" (entry 11) among the 29 subjects that may be devolved to Panchayats
- Article 47 (a Directive Principle of State Policy) casts a duty on the State to raise the level of nutrition, standard of living, and improve public health — the broad constitutional anchor for sanitation-focused welfare schemes
- SBM(G) is implemented as a Centrally Sponsored Scheme (CSS), requiring both central and state funding shares, with Gram Panchayats as the primary implementing and monitoring unit at the village level
- Sanitation coverage indicators (ODF, ODF Plus) also feed into broader public health and Sustainable Development Goal (SDG) monitoring, particularly SDG 6 (clean water and sanitation)
Village-level adoption of liquid waste infrastructure under SBM(G) illustrates the practical functioning of the 73rd Amendment's devolution of sanitation to Panchayats, with Gram Panchayats responsible for both building and maintaining the decentralised systems being counted in the 5.63 lakh figure.
- Villages with liquid waste management infrastructure: 5.63 lakh (as reported)
- SBM(G) Phase I launched: 2 October 2014; Phase II approved: February 2020, implementation period 2020-21 to 2026-27
- SBM(G) Phase II total outlay: about ₹1,40,881 crore (~₹52,497 crore direct budgetary support from Department of Drinking Water and Sanitation, remainder via convergence)
- Constitutional basis for Panchayat role: 73rd Amendment Act, 1992 — Eleventh Schedule entries 11 (drinking water) and 23 (health and sanitation)
- Related DPSP: Article 47 (State's duty to raise nutrition levels and public health standards)
- Related global goal: SDG 6 (Clean Water and Sanitation)
