The Water Map app shows you the nearby potable water sources around you. And you can also mark or identify a new source location. You can add different types of source, primary source water quality, and your water use information. The app shows you the sources with its contributory area, and with different colors and symbols. Besides the app shows you about the source water condition, accessibility and potential hazards. The most enhanced feature is it generates the water stress map across the globe with the crowd-sourcing info, and thereby help you understanding the global water condition.

This project is solving the Clean Water Mapping challenge.


Short Description

Background and Challenges

Potable water is inevitable but very limited natural resource. Besides the access to potable water sources is a great challenge, especially at the local level in the developing world. Water use in a community is affected by a lot of geographic and socio-economic parameters. All these information could be quite valuable in assessing and managing water resources on the planet. The spatial and temporal variation in the water source condition can potentially dictate the present and future water usage pattern and the critical regions. Informative water maps are likely to provide an efficient solution in this aspect. If a tool can be developed which will collect and process water source information from the crowd then it could be utilized to understand water accessibility and use on both the local and global scale.

Proposed Solution: Water Map App

The Water Map has been developed with an aim to provide a sustainable solution for the worldwide potable water resource management. Emphasizing on the crowd-sourcing, this app primarily connects mass people (non-technical) in contributing information for identification of the water sources, quality indicators and water use information. However it also provides a base platform for the technical users to incorporate relevant water information. What Water Map Provides:

Identify Water Sources and Water Access Info

Water Map is a mobile based web application (and at the same time available as the web application with all the functionalities) that enables a user to quickly find the nearby water sources on map from his location. He can also view the source type (e.g. well or stream), water quality and the area served by the source. The app allows to mark a new source (if found), and to add quality, accessibility and demand-supply information. The user also can identify or inform the sources which are under vulnerable condition, the type of hazard and the time frame. Water Stress Mapping

With the crowd-sourcing information, the Water Map generates global water stress map which is one of the key indicators in identifying critical regions and thereby contributes to the water access improvement strategies. Utilize TRMM Rainfall Data

As an alternate water solution, Water Map provides NASA's TRMM rainfall data on map which can be utilized to evaluate the rainwater harvesting potentials. With the user input, it generates a map showing the spatial distribution of harvested rainwater volumes. rainwater harvesting locations with the In addition water resource management.

Monitoring Water Sources

Water Map enables a subscribed user to monitor the condition of the selected water sources and it provides useful notifications. This could be very informative, especially for the admin or source authority users who are responsible for the operation and maintenance. If the source quality or accessibility condition is changed, then an automatic notification mail will be sent to the user's account.
