d in the global case studies, energy efficiency gains of between 5 and 2% appear realistic in the water cycle. However lower potential savings of 5 to 1% are more realistic in places where energy prices have already had significant impact. Two areas were identified as having the most potential for energy savings viz: Pumps and pumping : Savings of 5 to 1% on existing pu mps and 3 to 7% through improvement in pump technology. It was also identified that savings of 5 to 3% may be realised in pumping situations where the operational setup was changed from the design condition. 1-2 Aerobic wastewater treatment : Savings of up to 5% can be achieved on some aerobic wastewater systems through aligning control parameters with final effluent quality standards and up to 2% for activated sludge processes. Thus based on case studies from various regions, the GWRC global report concluded that by focusing on high energy demand areas .. pumping and aerobic wastewater treatment, water and wastewater utilities can achieve reasonable energy efficiencies. However the energy efficiency gains will depend on specific circumstances. 1.1.2 South African Studies .In response to the increased need to improve energy efficiency in South Africa as well as globally, the Water Research Commission (WRC) has, over the past 5 years, been funding number of water sector energy-related studies (.. Burton et. al., 2; Van Vuuren, 2; Frost & Sullivan, 2 and Swartz et.al. . The most prominent of these is the recently completed Energy Efficiency in the South African Water Industry: Compendium of Best Practices (Swartz et.al, , und ertaken as part of the GWRC study. The study made number of recommendations based on the energy efficiency case studies and best practices form South African utilities. summary of these recommendations which covered both supply and demand side management as well as the regulato ry side to incentivise th sector to adopt energy eff
