Build, operate, transfer is a well know known infrastructure implementation strategy. If competitive bidding is required, then the bidding should be between turn-key options to ensure that the best technology, design, construction, and technical support option is selected. .The AguaClara model draws on that model, but recognizes the need for greater emphasis on community assessment, capacity building, and a low level of oversight and ongoing technical support after the project has been fully transferred to the municipality or local water board. Separation of design and build is not supported by the AguaClara program because the level of technical expertise and the sophisticated hydraulic design can not be certified with inexperienced contractors.
