Classifying household water use into indoor and outdoor use from a rudimentary data set: a case study in Johannesburg, South Africa

Distinguishing between indoor use and outdoor use is becoming increasingly important, especially in water-scarce regions, since outdoor use is typically targeted during water restrictions. Household water use is typically measured at a single water meter, and the resolution of the metered data is ty...
