Abstract

This study proposes characterizing unauthorized water consumption and fitting multiple logistic regression models for detecting illegal connections. The research used monthly water consumption data from 42,131 single-family homes in Joinville, southern Brazil. The obtained models achieved accuracies ranging from 83% to 100% for detecting three types of fraud (unauthorized reconnection of a disconnected water service line, bypass, and direct connection). The results showed previous minor violations, tampering with water meters and stands, and non-compliance of meter installation with utility standards are related to illegal connections.
