It is recommended that recipients be required to assemble their own bucket filter. The drill bit that comes with the filter should be utilized by hand. Assembling the filter and drilling the hole for the recipient decreases their sense of ownership. An unclear understanding of how to disassemble and backwash the filter is the number one reason for filter/program failure. Each recipient should be required to demonstrate how to backwash the filter before leaving the assembly area. It is recommended that the recipient demonstrate how to backwash the filter three times using real filtered water each time. It is important that real and not imaginary water be used in demonstration. The recipient should disassemble, backwash and reassemble the filter three times (without assistance) before being given ownership of the filter. This is best accomplished by utilizing smaller breakout groups. This method is time-consuming, but insures a higher degree of success.
