Assessment of performance of selected Small-scale Water Infrastructure (SWI) for multiple use in Insiza District, Zimbabwe

  1. 1. P. T. Masuku T. E. Simalenga J. Jiyane A. Senzanje3rd International Forum on Water and Food November 15, 2011
  2. 2. Study background Rural water supply by low cost, simple technologies Multiple use of water infrastructure - means for improving livelihoods of rural communities Water supply systems dysfunctional within short period; poor performance in newly constructed SWI Ensuring conservation of quantity and quality requires optimal infrastructure performance 2
  3. 3. ObjectivesMain objective: To evaluate performance of small-scale water infrastructure (SWI) for multiple-use in Insiza DistrictSpecific objectives:1. To review the current water management practices at district and community levels2. To assess performance using four indicators: availability, condition, continuity and capacity indices3. To investigate socioeconomic factors that have most significant effect on performance of SWI4. To identify, quantify and compare the benefits obtained from SWI 3
  4. 4. Focus SWI: technical hardware that is available, used and managed by rural communities in capturing and collecting water for multiple water needs within their communal areas (Senzanje et al., 2011) Wells, boreholes, windmills, small dams  main water supply system for rural communities Windmill pump small dam deep well borehole 4Small-scale irrig scheme
  5. 5. (1) Current practices in water supply Collaborative engagement of Government and NGOs in rural water supply activities: DDF, RDC, AGRITEX, NGOs Ward level: trained pump mechanic responsible for repairing pumps and keeps maintenance records Community level: WPC ) responsible for minor functional maintenance, with pump minder - each water point has caretaker responsible for continuous monitoring 63 % of water points in with no WPCs nor pump minders; evidenced by state of SWI 5
  6. 6. (2)Performance availability capacity continuity condition overall performance  Availability 0.90  0.44 < Iav < 0. 65 0.80  Capacity 0.70  0.2 < Icap < 0.38  ContinuityPerformance ratio 0.60 0.50  0.45 < Icont < 0.72 0.40  Condition  0.24 < Icond < 0.81 0.30  Overall 0.20 performance 0.10  0.43 < I < 0.65 0.00 ward 1 ward 2 ward 17 ward 19 Ward 6
  7. 7. (3) Factors affecting performance Availability  Water quality  Increased number of people per SWI Capacity  Limited potential storage  Walking distance• Continuity  Alternative water source(s)  Households socioeconomic status• Condition  Alternative water source  Type of SWI  NGO intervention• Overall performance  Capacity 7  Condition
  8. 8. (4) Importance of SWI to communities(3) Importance of SWI to communities • Water for domestic, agriculture and livestock• Improved livelihoods and secondary benefits• Extent and type of use for different types of SWI for different communities depending on:  livelihood activities  availability of SWI type per ward  water point density  availability of alternative water source (s) 8  ease of operation
  9. 9. Conclusions1) Management structures in place at district level – implementation at community level2) Overall performance of SWI in Insiza District is poor. Major contribution from water quality and capacity3) Factors with significant effects on SWI performance :  lack of appropriate management structures and financial arrangements for SWI maintenance at community level  availability of other livelihood activities  availability of alternative water source(s)4) Importance of SWI dependent on the type and number of benefits derived from water use 9
  10. 10. How to ensure policy implementation at community level? How to ensure sustainability after intervention? Thank you 10
