Impacts of the ageing and rehabilitation of water pipes on residence times at the residential neighborhood scale

摘要: AbstractThe impact of ageing and rehabilitation on water residence times was evaluated in a looped drinking distribution network, using hydraulic modeling flow characterization. A reference scenario representing the best state knowledge studied area created realistic scenarios were applied to evaluate pipes times.Results showed that infrastructures, with consideration for pipe corrosion 20% leakage loss increase, lead an overall 10% time reduction. Considering non-uniform results localized impacts brought by changes patterns. coupled reduction leads small increases (2--8 h), local having least times.
