The extent of on-site leakage in selected suburbs of Johannesburg

Abstract

This study investigated on-site leakage on 182 properties with relatively new municipal water meters in well-established suburbs of Johannesburg. A methodology was developed to estimate the on-site leakage rate from readings taken from these municipal water meters, which was then adjusted to account for metering errors. The results were analysed in 2 categories: ‘Residential’ properties, which consisted of single houses on individual stands, and ‘Other’ properties, which consisted of non-residential users and blocks of flats. A high incidence, 64%, of measurable on-site leakage was found.
