Pipelines division keeps Thukela project flowing

Our pipelines division is currently engaged in a large project awarded by state-owned utility Umgeni Water.

The development forms part of the Lower Thukela Bulk Water Supply Scheme that will meet the water needs of an ever-growing local population by enlarging the utility’s bulk water infrastructure along the KwaZulu-Natal north coast.

The contract involves the installation of a 29km length of DN900 continuously welded steel pipeline with thicknesses varying between 6mm and 7mm between the Command reservoir near Mandeni and the Mvoti reservoir at KwaDukuza-Stanger.

Work on the pipeline is already at an advanced stage having commenced at Mvoti, and has already passed through KwaDukuza and Darnall with the Command reservoir nearly in sight.

Technical challenges for the Esor team will be the crossing of the Nonoti river using the existing road bridge as well as the fact that the pipeline traverses services like power lines, fibre optic cables and water and sewage pipes. Eight pipejacks are also being constructed beneath major roads and operational railway lines.

Additional work in the contract are the connection of the pipeline into the Mvoti reservoir, the construction of a new outlet chamber and connecting the outlet to the existing supply pipeline from Hazelmere. Esor will also conduct trials to the finished pipeline, including hydrostatic pressure testing and the evaluation of coatings and liners.

Personnel involved in the project include a team of 40 full-time Esor employees while temporary jobs have been created for around 200 locals. All specialist equipment used in the project is owned by ourselves.
