The last time Michael and I were in Kampala, we bought some blue PVC riser pipes to install in local boreholes. This week we had the opportunity to replace some corroded galvanized iron (GI) riser pipes with the PVC riser pipes. The PVC pipes were about half the price of the GI pipes and won't corrode. Corrosion of the riser pipes is one of the most significant causes of handpump breakdown we have seen in the Mundri area. The PVC pipes are also lighter and easier to work with than the GI pipes. We are working with the county water office to continue replacing corroded GI pipes with PVC pipes.
