Hammanskraal In the past weeks concerns about the quality of water in the Leeukraal Dam has prompted the City of Tshwane to temporarily shut down the Temba water treatment plant, which supplies water to Hammanskraal and surrounding areas. This after the Rooiwal Wastewater Treatment plant started discharging untreated effluent into the Apies River, which feeds the Leeukraal Dam, according to the City. So, some of the Hammanskraal residents haven’t had water for over 3 weeks.
