mWater helps governments, utilities and partners turn reliable data into better water, sanitation and health services. Its free platform is shared infrastructure: teams can collect and manage data, analyze it with common standards, and act on the results without having to build a new system for each project. More than 390,000 accounts across 198 countries and territories use mWater. Users control what they share, while reusable tools and public resources lower the cost of collaboration.
A shared foundation for better decisions
We actively contribute to open source initiatives
Connect systems without a bespoke project. The mWater Integrator helps users bring data from external APIs into mWater and publish selected mWater data as live CSV, JSON or GeoJSON feeds. An AI assistant can help set up imports in plain language. This makes existing government and partner systems easier to connect and helps keep shared decisions based on current data. The Integrator is free for all users and was funded by UNICEF Madagascar. See: https://www.mwater.co/blog/theintegrator
Put environmental context to work. mWater brings population and other environmental data layers into maps and analysis, so teams can relate facilities, assets and services to the places and people around them. Users can calculate population for mapped areas and combine data in calculated sources. A growing catalog of environmental data can support risk-aware planning and faster response. See: https://portal.mwater.co/resource_center/calculated_data_sources.html
Build once, share widely. mWater contributes reusable software and methods to the sector. Parts of the codebase and tools such as minimongo are open source; the core server and web portal are not. The public value also includes free access to the platform, open standards, and libraries that help teams use comparable questions, indicators and geographic data.

Water Asset Standard
The Water System Management Standard gives authorities, utilities and partners a common structure and definitions for water supply infrastructure, from sources and treatment to pipes and equipment. Funded in part by USAID and published in 2022, it supports consistent asset records that can be shared and used to plan maintenance and investment. Users have mapped nearly 1.1 million water assets using this approach. Read the blog: https://www.mwater.co/blog/asset-systems
Asset systems mapped
Sanitation Asset Standard
Building on the water standard, mWater published version 1.0 of an open standard in 2026 for both sewered and on-site sanitation. Its 27 asset types and 211 attributes give service providers, regulators and development partners a common language for assets such as pits, vacuum trucks, sewers and treatment plants. The standard can be used beyond this platform, helping data remain comparable and portable across institutions. Read the blog: https://www.mwater.co/blog/sanitation-asset-standard
This is a wikipedia-inspired repository of indicators as measured by well-tested question sets. Within one click, a user can build a survey that is tested and structured. Each indicator page includes references, has upvote capability, is comment-enabled, and shows up in searches by use so that better tested sets tend to be used more. An example of a highly used indicator set is the JMP Sanitation Service Level, which has been used in mWater over 25k times: /#/indicators/d4cc38cf93d849339b32a9d5f1f5630a
This has grown to the point that sector leaders approach us with funding for developing open source indicators in the library, such as with WHO’s Water and Sanitation for Health Facility Improvement Tool (WASH FIT): /#/indicators/cf2bb12ab8b84d3b8a401dc27dd8d66e
Population data
Columbia University’s CEISIN lab provides satellite demographic data that platforms like mWater have integrated to enable calculating population in relation to sites and assets: https://grid3.org/
This is how mWater allows users to add population density overlays in maps, and even calculate population by drawing a polygon on the map: /#/resource_center/population_density
Admin Region Library
Administrative boundaries for every country, from the country itself (level 0) down to level 5 where available, with a stable integer id per region and the full containment hierarchy on every row. Based on GADM 2.8 and continuously updated by mWater with national and partner boundary data. Two geometry variants: full resolution for spatial analysis, and simplified for drawing maps. All coordinates in EPSG:4326.
Next, mWater plans to expand this approach into a broader set of libraries. The opportunity is to curate, document and maintain reusable data, methods and workflows so each new partner can build on work already done. Environmental datasets and the Integrator make those libraries more useful: common evidence can be brought into local systems, combined with operational data, and shared back in practical formats. The expanded libraries are planned work, not a completed offering.
For donors, an investment in these shared resources can benefit many organizations beyond a single grant or geography. Useful support includes maintaining open access, improving documentation and quality, adding high-value datasets and standards, and helping local teams put them to work.
