Understanding the balance between customer use, supply pipe leakage & plumbing losses in water delivered to household properties
The aim of this project is to obtain a clearer understanding of the balance of customer use, plumbing losses and underground supply pipe losses in water delivered to customers and to provide an assessed plumbing loss value. In addition, we estimate the proportion of the water delivered to customers that could be attributed to internal plumbing losses and the proportion that could be attributed to underground supply pipe losses.
We find that average plumbing losses for unmeasured households are 1.4 +/-0.4 litres per property per hour (l/p/hr). Short lived but high flow rate continuous flows may add a further a 0.2 to 0.4 l/prop/hr. In some cases, this component may already be included in assessed night consumption.
The results of this study can be used to improve the measurement of total leakage by providing a country-wide average level of unmeasured household plumbing loss and guidance for carrying out company-specific plumbing loss assessments.
