Can you crowdsource water quality data?

The recently released Contextual Framework for Crowdsourcing Water Quality Data lays out a strategy for citizen engagement in decentralized water quality monitoring, enabled by the “mobile revolution.”

According to the WHO, 1.8 billion people lack access to safe drinking water worldwide. Poor source water quality, non-existent or insufficient treatment, and defects in water distribution systems and storage mean these consumers use water that often doesn’t meet the WHO’s Guidelines for Drinking Water Quality.

The crowdsourcing framework develops a strategy to engage citizens in measuring and learning about the quality of their own drinking water. Through their participation, citizens provide utilities and water supply agencies with cost-effective water quality data in near-real time. Following a typical crowdsourcing model: consumers use their mobile phones to report water quality information to a central service. That service receives the information, then repackages and shares it via mobile phone messages, websites, dashboards, and social media. Individual citizens can thus be educated about their water quality, and water management agencies and other stakeholders can use the data to improve water management; it’s a win-win.

Public Finance for Water in Sub-Saharan Africa

We know that water and sanitation services do not always recover their costs from tariffs. So, if communities or governments are to maintain the infrastructure properly, they depend on the public budget. And those expenditures must be predictable and transparent.To take a closer look at this issue, the World Bank analyzed public expenditure on water supply and sanitation from fifteen countries in Sub-Saharan Africa, assessing how much public money was budgeted for the sector and on what it was spent.
