CONCLUSIONS
Water loss is primarily an economic and not a technical issue PALM+ defines the target operating level for any network – also over extended time period PALM+ derives the future consumption and balances water loss reduction against new production facility PALM+ assesses the impact any investment will have
- n the tariff to ensure a viable solution before any
detail design has even started. PALM+ can maintain the efficient operation of a network in the future despite the dynamism.
