  • Adapting the IWA water balance to intermittent water supply and flat-rate tariffs without customer metering

    The International Water Association water balance is an approach applied worldwide for determining and analysing water losses in water distribution systems (WDS) up to the point of customer metering. Thus, water losses occurring ‘before’ a customer meter are at the expenses of the water utility while water lost or wasted ‘after’ the meter is paid for by the customer. This applies to systems ...
