Discuss the role of safe reuse of treated wastewater and community-led groundwater recharge in India's water security.

Water security means adequate, safe and sustainable water for all uses without exhausting the source. With the Stage of Ground Water Extraction at 60.63% and 730 of 6,762 assessment units 'Over-exploited' [4], the 9th India International Water Week 2026 on "Climate Resilient Water Management" [2] rightly recommended treated wastewater reuse and community-led recharge as twin pillars [1].

Safe reuse of treated wastewater: augmenting supply

• New supply source: urban India generates about 72,368 MLD of sewage [5]; recycling it for industry, irrigation and non-potable urban use frees scarce fresh water for drinking.
• Institutional backing: the National Framework for Safe Reuse of Treated Water gives states quality norms and business models [6], while the Power Tariff Policy, 2016 mandates thermal plants to use STP water available within 50 km [5].
• Pollution abatement: reuse cuts effluent discharge — 38% of 2,116 assessed river stretches were polluted on BOD norms [3] — directly aiding Namami Gange.
• The limiting factor: treatment capacity covers only 44% of sewage generated [5], and about 15% of that capacity is non-operational; Namami Gange had achieved only 3,806 of 7,000 MLD by December 2025 [3]. Untreated water cannot be reused.

Community-led groundwater recharge: securing the source

• Sustains service delivery: most rural schemes draw groundwater; though 87% of households have taps, only 76% are fully functional [3]. A tap in an over-exploited block — Punjab is at 76.47% [4] — risks running dry.
• Proven model: Atal Bhujal Yojana has gram panchayats prepare water budgets and Water Security Plans with mandatory 33% women's participation, releasing funds against measured outcomes [7].
• Demand-side caveat: recharge structures add water but do not reduce irrigation pumping; supply-side works must pair with crop diversification and micro-irrigation.

Together, the two close the water cycle — one returns used water to the economy, the other returns rainwater to the aquifer. Anchoring both in measurable outcomes rather than structures built, as JJM 2.0 and SDG-6 envisage, will convert IIWW's recommendations into genuine climate-resilient water security.
