2 Stellingen 1 Om armoede te minderen is het effectiever te investeren in familie pompen dan in grote water systemen 2 Om water gerelateerde ziektes te minderen is het effectiever te investeren in huishoud zuivering dan aanleg van waterleiding

3 New Low Cost options for Wells Pumps Storage Ground water recharge Irrigation Treatment (drinking water) Sanitation Hygiëne

4 Wells. Underlining Simple option to avoid collapsing of wells

5 Hand drilling of boreholes Rota sludge to 40 m deep Baptist to 80 m deep Cost $ 100 - 800 incl. casing, hand pump

6 Pressure pump 5 - 40 meters deep 20.000 installed in Bolivia Cost: $ 50 - 250 PUMPS EMAS

7 Treadle pump Suction pump for irrigation 1.5 million Asia and Africa Cost $ 15 – 100 Generates income $100 - 400 / year

8 Families,Small Communities 110.000 pumps, 5 million users Cost: $ 30 - 150 Rope pump

9 Models for 2m dug wells to 2“ boreholes

10 Nicaragua Increased rural water supply 3 x faster than other countries. 90% stay functioning Fit for family use Produced by local private sector, profit 90.000 installed. National standard

11 Etiophia, Zimbabwe, Malawi,.. 2 mln users now 10 mln in 2015? Zimbabwe may reach water MDG!

12 Ghana Worldbank funded project 80% defect after 1 year Errors Devil is in detail Simple is not easy…

13 50% of the hand pumps fail No ownership No management capacity From beginning include all cost Life cycle cost

14 Lessons learned For sustainability: Repairability From beginning include all cost (Life cycle cost) Profit for all involved, private sector Profit based sustainability, create value chains 3 C`s of marketing, Cost,…, … Simple is not easy

15 STORAGE Wire cement tank, Balanta tank Bricks, bamboo 1 bag of cement / m 3 Volumes 1 – 50 m 3 Other options Emas tank Plastic liners

16 Groundwater recharge Tube recharge Made by families Cap. 10-100m3 Cost 5 - 10 $ Other options Vetiver, Spate irrigation

17 IRRIGATION KB drip, Easy drip 0.01 - 2 Ha Cost 15- 20US$/100m2


19 50% of world poor, small farmers Can double food production with Inputs Access to market WATER Paul Polak IDE

20 FAMILY PUMP Irrigation of tomatoes + Domestic use for 10 families (Payback 6 months)

21 HYGIENE Tippy Tap, Wash bottle Families copy it (after critical mass) Educational for schools

22 SANITATION Urine Diversion Urine as fertiliser, 5 x the phosfate of feces Family food prod. Cost; 2/3 bag of cement

23 TREATMENT New disinfection options Aquatabs, PUR, Watasol

24 Silverdyne, Plation Users; 0.5 ? mln. Price; $20/unit/20ltr Cost; $4 - $6 + - Extremely simple - Functions one year - - High costs Safe storage

25 New Water filters Reduce diarrhoea up to 64% (Unicef / WHO) Candle CWP Life straw Siphon

26 No option is ‘the’ solution SODIS UV Combined Chemical (PUR) Chemicals Filtering Boiling PesticidesParasitesBacteriaVirusesHeavy Metals Turbidity


28 28 Efficiency of measures against diarrhea source: 3IE 2009) 1. 1.

29 Low cost options for almost all problems Improve water Quality ? - Household water treatment - Cover open wells,.. Increase water Quantity? - 3R, Retention, Recharge, Reuse - Hand drilling, locally produced pumps

30 Bacteria in wells? Disinfection or filter = safe water

31 Arsenicum, Fluoride, Pesticides, … ? Rainwater + HWT = safe water

32 Reduce distance to water point? Low cost boreholes & pumps Before After

33 Improve water sources? Upgrade open wells 3 mln in Africa Recharge + Cover + Pump = Improved water source. (MDG 7)

34 Economic benefit, Rope pump Nicaragua Cost 1 mln $ aid in training Benefit 100 mln $ increase GNP in 12 yrs Family with a pump 220 $/ year more than families without a pump. (Invest. 5000 fam. Icidri/ICCO) Zimbabwe; 1 pump = 80 people food all year Zambia; Rope pumps generate 100 – 400 $/ yr

35 Scale Up? Safe water - Household treatment - Awareness, Safe water = money More water - Training, Training, Training Vocational schools, Smart centres

36 Hands-on training

37 - Demonstration. Low cost options - Training. Production,O&M, marketing,.. SMART Centre

38 Spin off SMART centre Tanzania 20 trainers trained from 6 countries 12 private rope pump producers, well drillers 4000 rope pumps, 3500 wells upgraded, 400 boreholes, 15.000 water filters Cost reduction for water 40$ to 15$/cap

39 5 workshops trained in rope pumps WASH program Tanzania Winrock Funded by US aid

40 Information Smart series on Water Sanitation Water harvesting Hygiëne Disinfection Financing
