The optimal and sustainable management of water distribution systems still represent an arduous task.
In many instances, especially in aging water net-works, pressure management is imperative for reducing
breakages and leakages. Therefore, optimal District Metered Areas represent an effective solution to
decreasing the overall energy input without performance compromise. Within this context, this paper
proposes a novel adaptive management framework for water distribution systems by reconfiguring the
original network layout into (dynamic) district metered areas. It utilises a multiscale clustering algorithm
to schedule district aggregation/desegregation, whilst delivering energy and supply management goals.
The resulting framework was tested in a water utility network for the simultaneously production of
energy during the day (by means of the installation of micro-hydropower systems) and for the reduction
of water leakage during the night. From computational viewpoint, this was found to significantly reduce
the time and complexity during the clustering and the dividing phase. In addition, in this case, a
recovered energy potential of 19 MWh per year and leakage reduction of up to 16% was found. The
addition of pump-as-turbines was also found to reduce investment and maintenance costs, giving
improved reliability to the monitoring stations. The financial analyses to define the optimal period in
which to invest also showed the economic feasibility of the proposed solution, which assures, in the
analysed case study, a positive annual net income in just five years. This study demonstrates that the
combined optimisation, energy recovery and creation of optimized multiple-task district stations lead to
an efficient, resilient, sustainable, and low-cost management strategy for water distribution networks.
