29. Challenge Drinking WaterSupply 2.6 billion people have gained access to an improved drinking water source since 1990 which is an increase from 76% to91% globally. But there are more than 700 million people who still rely on unimproved water sources (surface water from lakes, rivers, dams, orsprings) With modern technique like solar pumps, UV filtration and desalination a strong improvement can beprovided Energy-efficient products can reduce the energy consumption up to 60% AQUASTAT;WHO

30. Technological background for sustainable efficiency byWilo • Wilo has invested in research anddevelopmentin the last years 60 -70 Mio. €/year. • Wiloiscooperating with German Universities and Institutes and is supportingthem. • The average number of patents, claimed by Wilo in the last years was > 20 /year. • Wilo is one of the innovation leaders concerning pumps to move water in the world. The high quality standards of the Wilo group are identical for all factories in the world. Sustainability by Wilo covers the entire valuechain. • Wilo has developped successfully new motor-technologies, hydraulics, steering and control systems and materials to achieve the highest efficiencies fro pumps and systems to movewater.

Opportunities in Waste WaterTreatment > 300.000 treatment plantsworldwide ~ 70 million basic treatment tanksworldwide Total potential of 50 % energy savings in waste water treatment 5 million tons CO2 per year, if we update all existing treatment plants to state-of-the-arttechnique http://www.grida.no/_res/site/file/publications/sickwater/SickWater_screen.pdf

37. Wastewater Treatment Plant Mannheim,Germany Background Since 1996 WILO submersible mixers operate successfully in the 5 activation lines, which are divided into 11cascades. Cascade 1-2: Bio-P (rectangulartank) Cascade 3-4: Preliminary denitrification (circulation channel) Cascade 5-7: Nitrification – alternating operation (circulationchannel) Cascade 11: Bivalent zone (rectangulartank) Mannheim is the 3rd largest plant in Germany, with 750 000 inhabitantequivalents. Challenge In 2012 water council Mannheim asked WILO to optimize the machinery regarding energy consumption and power input. A flow velocity of 0,20 – 0,25 m³/s was to beachieved.

41. WILO would welcome young (or not so young) researcher and/or practitonors from Africa to joint us on a temporary basis for exchange of experience and joint research practice; • WILO does not practice “white collar” research, while WILO is cooperating with “white collar researchers; • For WILO it is essential that all partners share the same values and principles concerning sustainability and business ethics, which are those of the UN and agreed upon by the German Government; • An important area of learning, where WILO is keen on possible Interaction and collaboration, is concerning cultural acceptance of innovative technology;

42. WILO best practice examples gives, in our understanding, a good example for research can be transformed into practice; • To transform research output into practice and to achieve tangible impact for our clients, is our business;’
