Each water source included in the data has been uploaded to the map.
Additional source characteristics, including the price and quality can be found by clicking on the 'Table' button above.
Notice this table is editable. Any edits to source attributes will be reflected in the following water source choice and demand predictions.
To add a source select the 'Add' button above. This will add a source to the end of the table, where source attributes can be input.
To delete a source, use the 'Delete' button in the rightmost column of the table.
To calculate demand, we need to know the population density at each location
in the study site.

grid cell, right-click on the cell.
To calculate demand, we also need to know the prevalence of private

Lastly, we need know how rain water consumption changes with the
Use the 'Chart' button above to input the percent of household water
demand that is supplied by rainwater in each month.
Click and drag the points to adjust the seasonality of household rainwater collection.
Now, using the information provided on water source attributes, population density, private source use, and rainwater collection, we can predict household water source choice and water demand.
Model parameters are based on water source choice research but can by adjusted by clicking the 'Edit' button above.
Click the 'Predict' button to predict household source choice and
This may take several minutes.
Water source catchment areas are displayed on the map, and show which sources households residing within each region are most likely to collect from.
A summary table that describes source demand statistics can be accessed by selecting the 'Table' button.
Community-level demand statistics can be found by selecting the 'Community' button.
