Some statistics on water loss (“non revenue water”): http://en.wikipedia.org/wiki/Non-revenue_water . Non Revenue water in developing countries can exceed 30%.

Interesting Avenues for Innovation:
- Linking Macro Economic and External Micro Data to measurement of demand for water
- Connecting economic growth and business growth to water usage
- Finding gaps between building infrastructure and lagging and leading economic growth
- Data Mashups – Weather and night usage
- Connecting electricity usage and water usage (e.g. in Germany)
- Data validation through relating available data to macro data (e.g. weather)
- Connecting Economics and human behavior to NRW (non-revenue water)
Other Resources and Software
Academic Resources (general : water economics)
The University of California at San Diego (UCSD) Center for Environmental Studies has a nice site called Water Economics with links to researchers, blogs, organizations, and data among many other resources. For a list of academic researchers, click here. It doesn’t appear complete in any way, however.
Columbia University’s Water Center, part of Columbia’s Earth Institute has as its director, Upmanu Lall, and staff here. One focus of the center is Data Analytics and Multi-Scale Predictions, in particular “Columbia Water Center is a leader in predicting seasonal hydroclimate forecasts and associated risk analyses. These forecasts are used for a variety of applications, including integrating climate forecasts into water allocation procedures for urban, industrial and agricultural consumers”
Coursera’s new class ‘Water Supply and Sanitation Policy in Developing Countries” (posted May-July 2014) taught by Dale Whittingdon (UNC Chapel Hill) and Duncan Thomas (University of Manchester) is a terrific introduction to the whole area of Water in developing countries. There are 6 short lectures: Introduction, Organizational Inefficiencies and Political Economy, Supply, Demand for Water and Sanitation, Outcomes and Climate Change, Development Paths.
