1. Contexte/Context Indonesian Annexation: 1975 1999 Infrastructure destroyed in 1999 Free democratic state: 2006 2016 Donor and Govt. capital investment in water systems: 2006 2016
2. Electric pump systems - definition Electric (mechanised) Grid or solar connection Community, clinics & schools Government / Partners Community
2. Electric pump systems - Problem Rural water supply systems are relatively easy to construct, but more difficult to manage effectively. Systems which include electrical pumping are particularly vulnerable to failure and long periods of down-time. Pumped systems are increasing in number as most springs and surface water sources have now been developed.
3.Objectifs / Objectives National pump system asset registration Assessment of BESIK capital maintenance Analysis of Cova Lima/Ainaro (O&M) trial Service Provider contract Functionality/Cost future modelling Training a team/s of pump system technicians for DNSA Technical design standards and O&M tools
4. Asset Registration - Method Location GPS Data Beneficiaries Pump details Pipes/Tanks Photos SIBS data link Functionality
4. Asset Registration - Results
5. Capital Maintenance Programme Method (2012 2015) BESIK (AusAid) funded Two rural pump system technician Reactive maintenance 54% site visit success rates Team based in capital
5. Capital Maintenance Programme Results (2012 2015) 134 site visits to 73 locations 427 maintenance actions performed on 73 systems 41% control panel (electrical faults) 28% pump faults 9% poor discharge construction 22% site surveys
5. Capital Maintenance Programme Costs (2012 2015) ~ 38,000 beneficiaries Programme cost: $103,100 Av. Annual cost/system: $590 Av. Annual cost/hh: $14 Av. HH contribution/annum: $6

8. Training Programme 15 new pump technicians Training duration: 6 months Overall costs: $87,000 Technical inputs from Lorentz and Grundfos staff
9. Guidelines and Analysis Tools Revision of Rural Water Supply Guidelines Electric pump system designs an specifications Energy consumption analysis (TOTEX) 95 sites analysed for energy consumption with energy cost (production) ~ $450,000 pa Strategic costing tool- projected cost tool urban/rural Investment in CapManEx vs. CapEx Tariff, population, coverage modelling
10. Leçons apprises / Lessons Learned Understanding how many systems, functionality and failure modes important Accepting the need for more human resources and budgeting realistically Advocating for the long term benefits of investment in O&M Evidence based decisions key
11. Conclusion Down times up to 2 years and more Two capital maintenance models trialled with increase in functionality from 63% to maximum 78%. Private partnerships need nurturing & monitoring Donor funding volatility and political change disruptive service delivery Government ownership of complex rural systems strongly advocated
