Background Information
For 12 months, WaterAid Uganda has been piloting an action research aimed at improving the functionality of handpumps, by changing the riser pipe from galvanised iron (GI) pipes to un-plasticised poly vinyl chloride (UPVC) plastic pipes. GI pipes are greatly affected by corrosion which leads to pipes developing holes and leakages as well as affecting the water quality especially when the water becomes brown and smelly. This poor water quality makes users revert to alternative, potentially unsafe sources with high microbiological risk. The solution to this would be to use stainless steel pipes but these pipes are very costly and heavy to install in deep wells.
The research team came up with an innovation of using heavy duty plastic pipes which don’t corrode. This technology is piloted in six selected handpumps in Masindi District, Western Uganda, which are installed with UPVC riser pipes and left to be used by the community for a year. This video summarises the findings of the study. Enjoy.
