- Description
- The traditional use of long-term average consumption records and “peak factors” to determine water network design criteria ignores allotment-scale diurnal water use patterns which impact upon detailed network dynamics. The diversity of allotment-scale diurnal water use patterns directly impacts on network dynamics. Demand management and/or rainwater tanks are likely to impact upon water supply network diurnal peak flows. Results presented in this study suggest that rainwater tanks with mains water trickle top-up produce different diurnal “mains water” use patterns that significantly reduce peak demand of the network; which subsequently impacts upon water supply network design criteria and provides opportunities to offset water infrastructure costs. Therefore there is a need to investigate the impact of diurnal patterns and source control measures, such as demand management and rainwater tanks, on water supply system peaks and network design criteria.
