Understanding Shared Sanitation in Peri-Urban India

In the rapidly expanding fringes of India's cities, known as peri-urban areas, access to basic sanitation remains a persistent challenge despite national campaigns like Swachh Bharat Mission. A groundbreaking exploratory study published in Scientific Reports, a Nature journal, on February 21, 2026, sheds light on how shared sanitation facilities—community toilets used by multiple households—play a crucial role in bridging equity gaps. Researchers from the University of California Berkeley, Boston University, and local Indian organizations interviewed 39 users in two Jharkhand communities, revealing that these free, well-maintained facilities are vital for the poorest residents who cannot afford private household toilets.

Peri-urban zones, the transitional spaces between rural villages and urban centers, house millions in informal settlements where land scarcity and poverty make individual toilets impractical. The study underscores that shared sanitation is not a fallback but a complement to home facilities, used even by those with private options when away from home for work or school.

The Context of Sanitation Progress in India

India's Swachh Bharat Mission (SBM), launched in 2014, has transformed the sanitation landscape. By 2026, over 120 million toilets have been constructed, benefiting 450 million people and declaring most villages open defecation free (ODF). Urban coverage has risen, with SBM Urban 2.0 targeting garbage-free cities and sustainable wastewater management by 2026.

Yet, National Family Health Survey (NFHS-5, 2019-21) data reveals gaps, especially in states like Jharkhand. State-wide, only about 65% of households have improved sanitation, with urban areas at 82% but peri-urban lagging due to density and poverty. Poorest quintiles rely heavily on shared or unimproved facilities, exacerbating health risks like diarrhea and stunting in children.

In Bokaro Steel City, the study's site, NFHS-5 shows lower access, highlighting how peri-urban inequities persist despite SBM incentives.

🧑‍🔬 Behind the Nature Study: Methods and Researchers

Led by Helen O. Pitchik and Isha Ray from UC Berkeley's School of Public Health and Energy & Resources Group, alongside Anoop Jain from Boston University and founder of Sanitation and Health Rights in India (SHRI) in Bokaro, the team conducted semi-structured interviews post-facility use. The 39 participants spanned genders, ages, and toilet ownership status in two unnamed peri-urban clusters.

• Deductive coding for access themes; inductive for emergent issues like mobility needs.
• Focus: usage patterns, cleanliness, safety perceptions.
• Affiliations blend US academia with Indian NGO expertise, emphasizing collaborative global health research.

Key Findings: Shared Facilities as Equity Equalizers

The study found clean, free shared toilets used routinely at home by both owners and non-owners of private facilities. Users praised accessibility and maintenance by SHRI, contrasting poor public options. However, outside home—markets, work, schools—toilet scarcity forces reliance on unsafe alternatives.

"Shared facilities are complements to, and not substitutes for, household facilities," the authors note, challenging SDG 6.2's exclusion of shared sanitation from "basic" access.

Health and Social Impacts of Sanitation Inequities

Poor sanitation hits women and children hardest: dignity loss, safety risks at night, disease vectors. Studies link shared poor-quality facilities to higher diarrhea, stunting. In Jharkhand, low coverage correlates with undernutrition.

Policy Gaps and Swachh Bharat's Peri-Urban Blind Spot

SBM focused household toilets, but peri-urban poor excluded due to costs (Rs 12,000 subsidy insufficient for space-poor). Budget 2026 cut SBM 26% to Rs 9,692 Cr, straining maintenance.

• NFHS-5: 8.4% India households share; higher in poor urban/peri-urban.
• Jharkhand urban: ~70% improved, but poorest quintile <30%.
• SBM Urban 2.0: 65,500 public blocks, but quality varies.

Study urges revising global targets to value managed shared sanitation.

Challenges in Maintaining Shared Facilities

Key barriers: funding, governance, user conflicts. Indian studies show unmanaged shared toilets dirty, unsafe. SHRI model: paid caretakers, water supply success.

Cultural taboos, overcrowding worsen inequities. Solutions: community management, subsidies for operations.

Solutions and Future Outlook

Authors recommend: Policy inclusion of shared in ODF metrics, invest in operations (not just construction). Scale SHRI-like models. Tech: IoT monitoring cleanliness.

With urbanization, peri-urban population to double by 2030. Integrated urban-rural sanitation partnerships needed. Researchers like Isha Ray advocate multi-disciplinary approaches, ideal for research jobs in development.

Conclusion: Towards Equitable Sanitation Access

The Nature study reframes shared sanitation as equity enabler, urging policy shifts for universal access. With SBM's legacy, India can lead globally by sustaining shared facilities alongside households.
