Draft BAR for construction and operation of a wastewater pipeline between the Baviaanspoort Correctional Services Facility Pump Station and the Baviaanspoort Municipal Wastewater Treatment Works

A completely new pipeline will be designed and installed, parallel to the existing pipeline. The existing pipe will be replaced with a new continuous welded High-Density Polyethylene (HDPE). Horizontal drilling will be done for the road and river crossings.
The construction methodology for the proposed pipeline will be as follows:
• Develop final pipeline route and mark with stakes.
• Where required, portion of the existing pipeline will be removed.
• Prepare the ground by grading and removing vegetation along the pipeline route.
• Topsoil removal and stockpiling outside the 1:100-year floodline of the Pienaars River.
• Staking of the centre of the trench area, laying or stringing of sections of the pipeline along the pipeline route.
• Pipe is welded and contoured (if required).
• Pipe is lowered into trench.
• Pipe is placed in the trench and backfilled with stockpiled soil.
• Where the pipeline crosses the Pienaars River, a borer is used to open a tunnel under the riverbed where the new pipeline will be installed.
• Rehabilitation of site.

Authorisation of the upgrade of the Baviaanspoort CFS, including the pipeline will enable DPW to recognise the rights of access to basic water supply and basic sanitation necessary to ensure sufficient water and an environment not harmful to health or well-being, as captured by the Preamble of the Water Services Act, 1997 (Act No. 108 of 1997).
