Heritage Cases

Ugu District Municipality, in its effort to continually reduce the Non-Revenue Water occurrence in the entire District. The project has been triggered by an excessive number of illegal connections along the rising main posing a hydraulic and operational challenge to deliver water to the KwaJali intermediate reservoir. The project is a direct pipeline replacement of the existing rising main pipe with a pipe of a similar diameter. The existing rising main pipeline with illegal connections will then be converted into a gravity main to supply areas around the KwaJali community. The existing rising main pipeline turned gravity pipeline will also supply a few localised stand pipes. The existing supply sources comprise of the Weza Water Treatment Works. The water from Weza WTW is distributed by pumping means to the KwaJali intermediate reservoir where is gravitates to the water reticulation system by means of the converted rising main pipe to gravity pipe. The water source is adequate to meet the supply. The proposal is to pump the water from Weza WTW to KwaJali reservoir via a new rising main pipeline. KwaJali reservoir will then supply the reticulation area by gravity means via the new gravity main pipeline. This proposal will effectively change the inlet chamber pipe configuration to include the new rising main and the gravity mains. The rising mains had already been replaced before the HIA was initiated. We were then asked to undertake a desktop to note what could have been affected. KZNARI Form I will be submitted with the HIA report.
