Strengthening wash systems for a water-secure nation
Water, sanitation, and hygiene (WaSH) remain one of India's most pressing development challenges. Growing water stress, declining water quality, climate variability, and gaps in sanitation continue to affect health, livelihoods, dignity, and resilience, particularly among vulnerable communities.
Nearly 600 million people in India face high to extreme water stress due to declining groundwater and increasingly uncertain rainfall. By 2030, water demand is expected to exceed available supply, intensifying pressure on agriculture, industry, and cities. At the same time, inadequate sanitation and hygiene continue to fuel disease and disrupt education, with women and girls bearing the greatest burden from limited access to safe sanitation and menstrual hygiene.
Addressing these interconnected challenges requires a shift from infrastructure delivery to integrated water system governance as a core pillar of nation building.
The Trusts act as an enabler by strengthening local institutions, knowledge, and practices that keep systems functional beyond programme lifecycles. Scientific planning, participatory design, innovative technologies, and behaviour change are brought together into a single integrated approach that responds to local needs and conditions. The goal is to build healthier, more equitable, and climate-resilient communities aligned with SDG 6: Clean Water and Sanitation for All.

Mission
India's water and sanitation challenges are deeply interconnected and increasingly shaped by climate variability. Building a resilient WaSH ecosystem requires integrated, system-wide solutions that advance water circularity, maximising water storage and efficiency, resource recovery, and recycling to reduce freshwater demand and strengthen long-term water security.
The Tata Trusts' WaSH strategy is anchored in a One Water approach, which recognises that all water uses are interconnected and drawn from the shared resource base. This is operationalised through a systems integration model linking source sustainability, service delivery, and long-term governance.
Water within communities serves three key purposes:
The Tata Trusts work alongside communities, local institutions, technical experts, civil society organisations, and government agencies to develop the systems that support long-term water security. The approach combines scientific knowledge with local engagement, promotes women's leadership in water governance, and builds local ownership so that solutions remain effective long after project implementation.
The Tata Trusts' WaSH programme is organised across three thematic areas that address immediate needs while strengthening the foundations for long-term sustainability. Across all three key priority areas, equal emphasis is placed on infrastructure, behaviour change, community stewardship, and local governance systems to ensure lasting impact.
The geographic footprint continues to expand through government partnerships, MoU-based collaborations, and a consortium model that brings together civil society organisations and technical institutions within a shared implementation framework.
