Th e Nelson Mandela Bay Municipality (NMBM) embarked on a large-scale water conservation and water demand management (WC/WDM) programme in 2009. The objective is to reduce non-revenue water (NRW) by 15% within ten years (nonrevenue water is the difference between 'system input volume' and 'billed authorised consumption'). Th e severity of the recent 2009 to 2011 drought in the Eastern Cape resulted in the municipality intensifying many of the WC/WDM interventions, allwith the view to reducing NRW and water wastage and improving the sustainability of water services. Since the drought broke and the NMBM lifted their emergency water restrictions, the focus of the Water Loss Programme has shifted, putting more emphasis on initiatives that reduce unbilled authorised consumption and apparent losses.
