A Strategy to Assess Water Meter Performance

Apparent water losses can be problematic to companies’ revenues. This type of loss is very difficult detect and quantify often associated with meter anomalies. study was motivated by a company’s challenge that links decrease in consumption meters’ malfunction. The aim develop strategy decreasing usage patterns, contributing performance assessment. basis the approach combination statistical methods. First, time series billed decomposed using Seasonal-Trend decomposition based on Loess. Next, breakpoint analysis performed seasonally adjusted series. After that, Mann–Kendall test Sen’s slope estimator are used analyze periods progressive changes consumption, defined breakpoints. A quantitative indicator this change proposed. successfully applied eight-time from Algarve, Portugal.
