WASHMobile is designed to identify, monitor, and address failing WASH infrastructure and to reduce water-borne illness rates in developing urban areas.  The system can be broken down into three components:

 

WATER ANALYSIS

Trained individuals regularly complete three simple water quality tests for each water source.  These tests measure turbidity, a metric to gauge the presence of physical matter, as well as total and E. coli coliforms, which indicate contamination with fecal matter.  Testing materials are obtained from IDEXX and Micrology Laboratories.  
 

 

DATA COLLECTION AND PROCESSING

The results from the water quality tests are submitted either via the internet or text message.  This data is then processed via an algorithm in the cloud that weights the three tests to yield a single water quality grade for each source that is indicative of the overall risk level.  Risk level determinations are based on WHO guidelines.  
 

 

INFORMATION DISTRIBUTION

This water quality information is then made available to relevant groups and individuals via an online map interface via SMS response and subscription services. Specific treatment options for contamination conditions present in a particular source can be requested and failing water points can be black-listed for repair. 
 

Information generated by the system is intended for two groups:

public water consumers
it is intended that individuals use this information to choose the cleanest water available to them in their  area and to treat collected water with an appropriate disinfection product.  
water regulatory bodies
the information will be used to repair failing infrastructure and will urge the adoption of consumer-oriented policies by making them accountable to established water standards.
