  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. PUMPSEMAS • Pressure pump • 5 - 40 meters deep • 20.000 installed in Bolivia • Cost: $ 50 - 250

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

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

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

  14. Lessons learnedFor 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 / m3 • Volumes 1 – 50 m3 • Other options Emas tank Plastic liners
