Access to safe water, sanitation, and hygiene remains a foundational development imperative, directly linked to public health outcomes, gender equity, and sustainable development goals across low- and middle-income countries.
The WHO/UNICEF Joint Monitoring Programme (JMP) serves as the authoritative mechanism for tracking WASH progress worldwide, publishing periodic reports on household drinking water, sanitation, and hygiene. These reports establish standardised service ladders — from no service to safely managed — enabling cross-country comparisons and evidence-based policy adjustments.
The JMP defines 'safely managed sanitation' as use of improved facilities that are not shared with other households and where excreta are either treated on-site or transported and treated off-site. This standard moves beyond mere toilet construction to address the full sanitation chain, including faecal sludge management — a dimension often neglected in national programmes.
Open defecation-free status, as tracked under JMP, requires that no community member practises open defecation, but it does not mandate use of 'improved' facilities exclusively. India's Swachh Bharat Mission achieved ODF declarations at scale, yet sustaining behaviour change and ensuring facility quality remain persistent implementation gaps.
Fragmented inter-ministerial coordination between water, health, and rural development departments weakens WASH delivery. Decentralising WASH governance to gram panchayats, backed by dedicated untied funds and third-party verification, is critical to converting infrastructure investments into durable public health gains.
Achieving universal safely managed WASH requires bridging the gap between declared targets and verified outcomes. Robust monitoring, community ownership, and integrated governance — rather than infrastructure alone — will determine whether WASH commitments translate into lasting health equity.
