1 Innovative and affordable WASH self-supply technologies (EMAS SCHEME) By Lahai Ensah Bunduka National Project Coordinator WASH self-supply, Sierra Leone

2 WASH self-supply (EMAS CONCEPT) Funded by: DFiD/UK Aid and implemented by The German Organisation called Welthungerhilfe, formally called German Agro-Action. Project duration-july 2012 to Dec.2013 (pilot) Project locations-western rural district (ward c) and Kenema Nongowa chiefdom

3 Project locations

4 Main outputs 1. Specialized training of 80 EMAS-WASH technicians and 10 TOT 2. Establishment of 30 demonstration sites 3. Creating increased demand for WASH selfsupply 4. Enhancing the establishment of 15 WASH self-supply start-up businesses 5. Improving sector learning and capacity building of stake holders

5 Achievements 75 WASH technicians already trained and 23/25 TOT 25 Demonstration sites established and 100 private systems completed across the country 135 private systems installed 15 talk shows and 15 community outreaches held 13 WASH business units registered and two WASH regional cooperative organisations formed. 160 beneficiary household/ngo staff from partner organizations trained

6 ACHIEVEMENT ACHIVEMENT GOAL GOAL ACHIVEMENT Goals 1-training 2-demo sites 3-media/out 4-busi. Units 5-cap. Build.

7 Our technology options 1. Self-made manual pumps; hand and pedal 2. Upgraded VIP and surface composting latrines 3. Rain water harvesting 4. Shower cubicles 5. Domestic hygiene systems 6. Ferro-cement water storage tanks 7. Irrigation and distant pumping scheme 8. Locally made solar for hot water bathing 9. Manual drilling

8 Water- an added value approach Kitchen Hot water bathing Latrine Manual pumping of water Storage tanks Farmirrigation Shower room

9 Hygiene Simple and effective domestic and personal hygienehand washing, pot rack and shower bathing

10 MANUAL DRILLING Introductory training conducted Five test drill wells in Freetown Rural-paid by individuals; all functional since july 2013 Drilling method-suction and washing Drilling of 30 metres can be done in two days, 6 drillers Average cost of a drilled well 30 metres depth Le 2.5 to Le3 million

11 : TOOLS NEEDED A 4 metre high derrick crane made of iron bars and fastened with 4 tension rods lever and shaft, a small stick to pull the rope and one or two pulleys and a resistant rope. 60 metres of drill pipes = 20 bars, 3 metres long, and two pieces 1 metre each, with 1 inch Reinforced nipples, a drill bit, one or two holders, 7 metres of 3/4" hose, and a mud emas pump. pipe press to fasten the drill pipe for screwing and unscrewing its pieces, 2 pipe wrenches, a piece of wire mesh to sift mud, two buckets and a steel brush.

14 EMAS MANUAL DEEP DRILLING (WASHING) This drilling method can drill to a depth of 100 metres in soils of fine material which do not contain stones. The drilling diameter is only 2 inches and the average yield of these EMAS wells is 1 litre per Second litres per hour.

15 THE EMAS DRILLING SYSTEM USING SUCTION thick sand and small stones or pebbles are encountered can be used by simply adapting a check valve below the holder. However if a pebble size greater than 2 cm is found, then bars of a larger diameter are required together with a larger valve. The drilling liquid should be strongly thickened to be able to carry pebbles. This is not always possible.

17 Sanitation Upgrading, comfort and improving health

18 Challenges Coordination and networking amongst partners and stakeholders Short project duration (18 months); only one dry season Servicing customer call across the countryproject locations in only two districts Transport constraints especially for pipes 6 metres length Dependency syndrome of Sierra Leoneansunwillingness to pay for wash services Poor town and household planning

19 Challenges cont. Difficulty in rehabilitating large diameter household wells too expensive for household level Culture of building very deep and wide toilets Perception - composting toilets, manual pumping of water is poverty, rain water is not good ; not useful Quality control monitoring is a big challenge Free Wash services delivered by big donors/ngos/politicians Lack of pro-activeness of trained technicians Poor quality materials and equipment-pipes and tools Pilot project not clearly understood

20 Lessons learnt Big ignorance in sector about rain water harvesting-soft subsidies for large tanks Sierra Leone does not lack water; water resource management is the problem Women, children, aged and the physically challenged remain largely marginalized in current WASH system designs-squatting toilets, head carrying of water over long distances

21 Lessons learnt cont. Underground water is consistently being polluted-this may have serious health implications Water catchment areas across the country are heavily over exploited and mismanaged Treatment of water for domestic use can work best when knowledge is strengthened at the household level Self supply succeed best where there is proper policy frame work and a willing leadership direction

22 Lessons learnt cont. Profit based approach more demo. sites due to financing options e.g. offering pay-back periods, village savings and loans clubs/osusu Quality control monitoring-own funds to strengthen quality control coop. Use of more local materials and product range will increase investment Customer feed back options will help determine product choice and appro. Marketing strategy

23 Lessons learnt cont. Every individual welcomes change that improves quality of his life-just need right options and right opportunities and the right time

24 One concept direction Clean water Good sanitation Effective hygiene Sound health for every one
