| dc.description.abstract | Across Sub-Saharan Africa, approximately 500 million people rely on groundwater, with about 200 million depending on boreholes for their water supply (Danert, 2022). In Uganda, around 67% of the rural population relies on boreholes, with over 63,000 installations across the country (Ministry of Water and Environment, 2023).However, corrosion in borehole components presents a significant challenge, particularly when using metal components like steel and iron, which are prone to corrosion when exposed to groundwater. Traditionally, boreholes have depended on metallic pipes for structural integrity, but corrosion has resulted in the degradation of water quality, frequent component failures, and increased maintenance costs (Smith, 2015). These challenges are exacerbated in groundwater environments characterized by low pH, high levels of dissolved oxygen, salts, and acidic conditions (Jones & Smith, 2018).In Nyakwae sub-county, Abim District (Uganda-Karamoja region), groundwater contamination with low-pH water of high salinity and chloride has exacerbated corrosion issues. This has resulted to breaking down of borehole parts frequently,that are normally the only sources for drinking water to the local communities (Mugisha &Okurut, 2019).In response to this continued challenge, the government of Uganda banned use of galvanized iron (GI) pipes in 2016 as borehole hand pump riser components and promoted alternative materials that can withstand ground water conditions within the high-hardness range (The Republic Of Uganda Ministry Of Water And Environment, 2016). Whilst stainless steel and polyvinyl chloride (PVC) pipes are recommended for bore holes, there have been many instances of failures in pipe materials or poor performance from the system, which warrants additional research to identify even more long-lasting materials.Testing and evaluation was conducted so that material with unplasticized could be utilized in borehole system components to mitigate the effects of corrosive damage. | |
