Heritage Cases

The project entails the provision of bulk services (water and sewage) to the Hammanskraal West area. Bulk water pipeline: The proposed steel bulk water pipeline will be 800mm in diameter and approximately 5.2km in length. The bulk water pipeline will be constructed from the Hammanskraal West Reservoir in an eastern direction (reservoir access road) for approximately 150m. The construction of the pipeline will then continue in a northern direction for approximately 3.3km and in an eastern direction for approximately 1.7km where it will connect with an existing pipeline. The pipeline will follow the same route as the existing DN600 pumping main, but will as far as possible be constructed on the opposite side of the road. The pipeline will be constructed: • Along the Northern side of the reservoir access road • Along the western side of the road on the North-running section • Along the southern side of the road on the East-running section The scope includes the connection of the proposed bulk water pipeline to existing pipework at the Hammanskraal reservoir and connection to other proposed and existing pipelines. Bulk sewer pipeline: The proposed concrete bulk sewer pipeline will be 525mm - 600mm in diameter, except at 3 major road crossings where it will be 900mm in diameter, and is approximately 3.4km in length. The bulk sewer pipeline will follow, for the most part, approximately the same route as the existing DN315 / DN400 outfall sewer that serves Hammanskraal Ext. 2, but will be constructed on the opposite side of the stream in the middle section. The proposed pipeline will be constructed from a point on the northern side of Hammanskraal Ext. 10 where it will collect flow from Ext. 4. The pipeline will cross the K224 Provincial road (Harry Gwala Avenue) and continue in an easterly direction to cross the unnamed road towards Temba. From there it will run in a northerly direction parallel to and on the western side of the existing outfall sewer serving Ext. 2 and then in a north eastern direction to a specific point. The pipeline will continue along the northern side of the unnamed tributary of the Apies River in an easterly direction where it will cross Temba Road and will connect at an existing manhole to the existing 1200mm dia. outfall sewer that is running on the western side along the Apies River to the Temba Wastewater Treatment Plant.
