Project Description
The Milnerton bulk sewer upgrade will be completed in phases.

Phase 1 comprises the construction of a new bulk sewer, sand trap and screening facility in Montague Gardens to increase the capacity and reliability of the bulk sewer system.

The project will include:

• microtunnelling a new 3.78-km-long Montague Gardens bulk sewer, 970 mm in diameter, around the eastern and northern boundaries of the Montague Gardens industrial area.
• microtunnelling a new 300-m-long bulk outfall sewer, 1 350 mm diameter, at the Koeberg road pumpstation to accommodate the combined flow of the existing Montague Drive bulk sewer and the new Montague Gardens bulk sewer.
• constructing a new sand trap and screening facility at the Koeberg road pumpstation.
• extending and diverting the existing 700-mm-diameter Edgemead bulk sewer and 450 mm diameter Century City bulk sewer into the new infrastructure.

Phase 2 entails future trenchless rehabilitation of the existing Montague Drive bulk sewer.

The scope of work for Phase 2 includes:

• trenchless rehabilitation of the estimated 4-km-long existing 700-mm-diameter to 975-mm-diameter Montague Drive bulk sewer.
