Kathmandu, July 30 (Ecosphere News) - Nepal does not maintain a single, fixed national ranking that places all 753 local government units (LGUs) from first to last for water supply and sanitation performance. Instead, the Ministry of Water Supply monitors and compares municipal progress through the National WASH Information Management System (NWASH-MIS), where scores are updated dynamically as local surveys and service data are validated.
The NWASH platform evaluates municipalities using a combination of WASH plan completion, infrastructure functionality, water quality, sanitation coverage, and safely managed service indicators, making local performance assessments more responsive to changing ground realities than a static annual leaderboard.
Provincial Trends Reveal Clear Regional Disparities
Recent NWASH and Joint Monitoring Programme (JMP) analyses show significant differences among Nepal's seven provinces.
Gandaki and Bagmati Provinces continue to perform strongly on most WASH indicators. Gandaki was the first province to achieve 100 percent basic sanitation coverage, while Bagmati has consistently demonstrated stronger institutional capacity and wider access to piped drinking water systems.
Koshi, Lumbini, and Sudurpaschim Provinces fall into a middle-performance category. These provinces have achieved basic sanitation coverage above 95 percent in many local governments, but challenges remain in maintaining water supply functionality and controlling bacterial contamination, particularly in rural and peri-urban systems.
The most significant gaps are observed in Madhesh and Karnali Provinces. Madhesh continues to lag behind the national average in basic toilet coverage, while Karnali faces severe topographical and infrastructure constraints, resulting in the country's lowest levels of piped water access.
Basic Access Is High, but Safe Management Remains a Major Challenge
National NWASH status data indicate that Nepal has made substantial progress in expanding basic WASH infrastructure, yet the transition to safely managed services remains limited.
| Service Indicator |
Basic Coverage |
Safely Managed Coverage |
| Drinking Water |
~95% |
~16-19.1% |
| Sanitation |
~98.9% |
~51% |
This means that while most households have access to an improved water source or toilet facility, far fewer receive water that is consistently available, accessible, and free from contamination, or sanitation services that meet full hygiene and waste management standards.
Key Indicators Used to Score Municipalities
Federal authorities and development partners assess local governments using several core benchmarks:
- WASH Plan Completion: Municipalities receive higher scores when they have prepared and validated official WASH plans through the NWASH Planning Tool. To date, 326 of Nepal's 753 municipalities have completed this process.
- Infrastructure Functionality: A significant proportion of water supply systems suffer from operational problems. National assessments suggest that only 25-30 percent of constructed water infrastructures are fully functional.
- Water Quality: Municipalities are heavily affected by poor water treatment and monitoring practices. National testing indicates that approximately 71 percent of sampled water sources contain E. coli contamination, posing serious public health risks.
- Institutional “Star” Classification: Schools and community institutions are graded from No Star to 3 Stars based on the availability and operation of handwashing stations, toilets, menstrual hygiene facilities, and hygiene management systems. Many rural municipalities still have few or no institutions meeting the 3-Star standard.
Real-Time Dashboards Replace Traditional Rankings
Because NWASH data are updated continuously, experts emphasise that municipal comparisons should be made through live dashboards and validated scorecards rather than through unofficial static rankings circulating online.
Municipalities can access:
- NWASH Municipality Dashboards for province-, district-, and palika-level comparisons;
- Municipal Sanitation Report Cards developed with support from UN-Habitat and WaterAid Nepal;
- Municipal WASH Vulnerability Portals that apply JMP indicators to assess risks in schools, healthcare facilities, and underserved communities.
Data-Driven Governance Becoming Central to Nepal's WASH Sector
WASH specialists say the increasing use of NWASH-MIS represents a significant shift toward evidence-based local governance. By linking planning, budgeting, infrastructure monitoring, and service quality assessment within a single national system, the platform is helping identify municipalities that require urgent technical and financial support.
However, the data also highlight that Nepal's next major challenge is not simply expanding infrastructure, but ensuring that water and sanitation services are functional, safe, climate-resilient, and sustainably managed for all communities.
