The Ministry of Water and Environment has suspended the use if galvanized iron (GI) pipes in boreholes. All new borehole sources should now be installed using stainless steel pipes or PVC pipes.

The use of these alternative materials should ensure that specifications are in compliance with Uganda National Bureau of Standards (UNBS) to improve on the quality, consistency and effectiveness of newly constructed and rehabilitated boreholes across the country.

As of June 2016, the functionality of rural water facilities was 86% out of 35,893 boreholes, 5,742 were reported to be non-functional. Out of 20,175 shallow wells, 4,218 were non-functional.

The sector recognizes that low functionality negatively impacts on the objectives of providing potable water, better health, increased school attendance and retention and improved hygiene.

Specifically, the following industry standards shall be met to ensure that all boreholes parts are fully complaint namely;

  • US403:2002 Standard specification for deep well CBMS hand pump (model U3)
  • US404:2002 Standard specification for extra deep well CBMS hand pumps
  • US405:2002 Standard specification for shallow well hand pumps (model U2/U3)
  • US406:1995 Standard specification for deep well hand pump (model U2)

Additionally, all polyethylene (PE), polypropylene (PP), Un-plasticized Poly vinyl chloride (PVCU) and stainless steel pipes with associated fittings used shall be designed to comply with all pertinent UNBS standards.
