Water and sanitation support
Overview
What is water and sanitation support?
Water and sanitation support encompasses the planning, funding, delivery, and governance of safe water supply, reliable sanitation facilities, and hygiene promotion. It includes infrastructure such as pipelines, pumps, latrines, and handwashing stations, as well as systems for operation, maintenance, and governance. Effective WASH support also integrates capacity building, behavior change communications, data collection, and long-term resilience planning to ensure services endure in the face of growth and shocks.
Why it matters for health and development
Access to safe water and sanitation is a fundamental driver of health. It reduces the burden of waterborne diseases, supports maternal and child health, and lowers malnutrition risks linked to repeated infections. Beyond health, reliable WASH services enable children to attend school, empower women and girls through safer facilities and time savings, and contribute to economic productivity by reducing illness-related absenteeism and medical costs.
Global landscape
Current access and disparities
Global progress on universal water and sanitation access has been uneven. Urban areas often enjoy better service levels than rural communities, and households in low-income settings frequently face higher costs, intermittent supply, and unreliable sanitation access. Disparities also exist across regions, with some countries achieving near-universal access while others struggle with infrastructure gaps, governance challenges, and insufficient investment.
SDG 6: Clean water and sanitation for all
The Sustainable Development Goal 6 aims to ensure availability and sustainable management of water and sanitation for all by 2030. Achieving this requires universal access to safe drinking water, adequate sanitation, and improved water quality, alongside sustainable water resource management. Progress hinges on inclusive governance, sustained financing, and resilient WASH infrastructure that reaches the poorest and most marginalized communities.
Financing and funding
Public funding and subsidies
Public funding remains a core driver of foundational WASH services. Government budgets, earmarked subsidies, and capital investments support the construction and maintenance of water supply networks, sanitation facilities, and hygiene programs. Equitable subsidies and tariff designs can help ensure affordability for low-income households while maintaining the financial viability of services and incentivizing proper use and maintenance.
- National and local government allocations for WASH projects
- Subsidies and cross-subsidies to support poor households and vulnerable groups
- Grants and concessional financing for essential infrastructure
Private sector and blended finance
Public-private partnerships and blended finance combine public capital with private investment to mobilize larger sums and accelerate service delivery. Blended approaches can lower funding risks, attract long-term investors, and enable performance-based contracts that reward reliable service. Donor guarantees and technical assistance often accompany private investment to ensure social objectives are met.
- Public-private partnerships that align service quality with affordability
- Results-based financing and performance contracts
- Blended concessional funds to bridge financing gaps
Programs and interventions
WASH in healthcare facilities
WASH standards in healthcare facilities are essential to prevent infections, protect patients and staff, and improve care outcomes. Programs focus on reliable water supplies, clean toilets and handwashing stations, safe waste management, and hygiene promotion campaigns tailored to clinical workflows. When healthcare facilities are properly equipped, patient safety improves and the quality of care rises.
Household and community sanitation solutions
Household and community sanitation interventions combine hardware provision, sanitation marketing, and behavior change to reduce open defecation and improve usage. Approaches include affordable latrine technologies, maintenance plans, and community-led initiatives that foster local ownership. Effective programs address cultural norms, gender considerations, and the specific needs of disabled or elderly residents.
Implementation strategies
Community engagement
Community involvement ensures that WASH interventions reflect local priorities and gain sustained support. Strategies include participatory planning, local committees, capacity-building for maintenance, and transparent communication about costs, service levels, and expected outcomes. Engaged communities are more likely to maintain facilities and adopt healthy behaviors.
Monitoring, evaluation, and data
Robust monitoring and data systems enable tracking of water quality, service reliability, and usage patterns. Regular evaluation helps identify bottlenecks, measure health and development impacts, and guide adjustments. Open data and accountability mechanisms build trust and support evidence-informed decision-making at all levels.
Gender and inclusion
WASH programs must address gender dynamics and promote inclusive access. Men, women, and non-binary individuals may experience different barriers to use and safety. Design considerations should include accessible facilities, privacy, menstrual hygiene management, and services that reach people with disabilities, the elderly, and marginalized groups.
Equity, resilience, and inclusion
Gender, safety, and marginalized groups
Equity in WASH means prioritizing safety, dignity, and access for all. Programs should mitigate gender-based safety risks, reduce barriers faced by marginalized communities, and ensure that services meet diverse needs. Inclusive design and targeted outreach help close disparities and strengthen community resilience.
Climate resilience and disaster response
WASH infrastructure must be resilient to climate risks and natural disasters. This includes flood and drought-proof water sources, backup power and storage, and rapid repair mechanisms after shocks. Integrating WASH with broader resilience planning reduces vulnerability and supports faster recovery for affected communities.
Partnerships and governance
Governments, NGOs, and donors
Effective WASH governance depends on coordination among governments, non-governmental organizations, and donors. Clear roles, shared targets, and aligned funding streams help minimize duplication and maximize impact. Strong stewardship at national and local levels supports sustainable service delivery and accountability.
Policy and regulatory frameworks
Clear policies and regulations set service standards, protect water quality, define pricing and subsidies, and establish oversight mechanisms. Effective regulatory frameworks incentivize performance, ensure affordability, and create an enabling environment for private investment while safeguarding public interests.
Measurement and indicators
Water quality
Regular testing for microbial and chemical contaminants ensures water is safe for drinking and domestic use. Standards and enforcement, combined with safe storage and handling practices at the household level, reduce health risks and build public confidence in services.
Sanitation coverage and usage
Measuring access to sanitation facilities and actual usage helps gauge progress toward eliminating open defecation. Indicators consider reliability of facilities, maintenance, and user behavior to reflect real-world conditions beyond mere installation.
Service continuity and reliability
Continued water supply and dependable sanitation services are critical for trust and daily life. Indicators track supply interruptions, maintenance response times, and system resilience to seasonal or hazard-related stress.
Health and development outcomes
Linking WASH inputs to health indicators (such as diarrheal disease rates) and development outcomes (like school attendance and productivity) demonstrates the broader impact of investments. This evidence supports ongoing prioritization and funding for WASH programs.
