River Embankment Protection - Onseepkans
Onseepkans, Northern Cape

River Embankment Protection - Onseepkans


River embankment protection at Farm Raap-en-Skraap near Onseepkans. Water for approximately 300ha of export quality table grapes is abstracted at Raap-en-Skraap. The embankment protects an inlet canal from where water is abstracted with multiple pumps. The embankment juts out into the stream and without protection is vulnerable to erosion due to the high water velocities in the river. The project was funded by the farm owners Keboes Fruit Farms which is a subsidairy of Karsten Farms (Pty) Ltd.

Sedibeng Pipeline Project
Springbok, Northern Cape

Sedibeng Pipeline Project


The Sedibeng pipeline project is funded by Department of Water and Sanitation.  The project entails the upgrading of existing 120km pipelines from the Treatment Plant at Henkries alongside the Orange River to Springbok.  The works include the replacement of existing pipelines, upgrading of 4 main pumpstations and construction of concrete reservoirs.  The installation of new pipelines to the communities of Concordia, Carolusberg and Nababeep is also part of the project.  The approved budget for the project amounts to R500m.  The first phase of the construction of the main pipeline will be completed in May 2016.  The planning and design of the next phase is already in an advanced stage and construction will commence middle 2016.

Construction of New Dissolved Air Flotation Facility at AH September Water Treatment Works
Upington, Northern Cape

Construction of New Dissolved Air Flotation Facility at AH September Water Treatment Works


This project was initiated due to the increasing frequency of algal blooms in the Orange River due to eutrophication. The high occurrence of algae tends to block sand filters hindering the production of potable water. A dissolved air flotation plant was constructed to remove the algae from the water.

This facility consists of the following structures or process units:                                 

  • Construction of an earthworks platform to design levels
  • 6 x dissolved air flotation tanks with dimensions of 9m x 9m constructed from reinforced concrete.
  • Recycled water sump constructed from reinforced concrete. Plant room for mechanical and electrical equipment.
  • Cladded structural steel canopy over the total facility 3 x stainless steel saturators manufactured from stainless steel with 9-bar pressure rating 4 x 40kW recycle pumps (3 duty + 1 standby)  3 x air compressors (2 x duty + 1 standby) + common air receiver tank Stainless steel whitewater pipework (160mm dia to 250mm dia).
  • Large diameter underground connector pipework (450mm dia to 800mm dia). Refurbishment of the existing Chemical Dosing equipment              
  • Minor site works (Storm water management, block retaining walls, landscaping)

Rehabilitation of Skoenmakers River
Port Elizabeth, Eastern Cape

Rehabilitation of Skoenmakers River


The project is about conducting feasibility studies on river structures and investigation on the Skoenmakers River which has been utilised as a conveyance system and spillway to Darlington Dam since 1981. The feasibility studies are necessitated by deterioration of the river channel over the years which have resulted in the erosion of the river embankments, creation of an island in the river bed, loss of vegetation, erosion of some bridge-supporting embankments and transportation of vegetation and silt downstream. Investigate the impact of water releases down the river bridge and compilation of a river rehabilitation strategy to improve access across the river and to halt further degradation of the river.

The aim of the assignment is to assist the National Water Resources Infrastructure (NWRI) in understanding the impact of water release down the Skoenmakers River in an effort to have intervention measures put in place to upgrade the river bridge structures and prevent further deterioration of the river embankments and bed to minimise the loss of human lives, livestock and wildlife in the area.

Rapid Loadout Terminal – Storm Water Management Plan
Emalahleni, Mpumalanga

Rapid Loadout Terminal – Storm Water Management Plan


Formulation of Storm Water Management Plan: 

1 ) Identify clean and dirty water areas according to GN704
