|Name of Project||Kasane Water Treatment Works|
|Start Date||February 2021|
|Expected Completion Date||2023|
|Client||Zhong Gan Engineering and Construction (Botswana) Ltd|
Approached by the popular Botswana contractor, Zhong Gan, WEC Projects was successfully awarded a contract to complete a new custom-designed drinking water plant in Kasane. Along with other sub-contractors such as Bergstan South Africa, WEC Projects will be completing the full mechanical, electrical and telemetry scope of works for the plant.
WEC Roles and Responsibilities
The plant will use raw water from the Chobe River in Botswana. The biggest challenge is that the Chobe River, as well as with most surface water within Botswana, requires a proven and well-designed process to treat the water to the required standards.
In the selection and design of the treatment plant, the following unit operations will be used:
- Lamella clarification
- Sand and carbon filtration
- Chlorine dioxide disinfection
The combination of these unit operations within the treatment process, will ensure the facility achieves the treatment objectives. WEC will also provide value engineering throughout the design and consultation phases, which will offer suggestions around the final delivery of the project. We strive to always improve the project, even from the design phase. Zhong Gan was able to successfully win the tender, along with nominated sub-contractors, WEC Projects and Bergstan.
WEC Projects will be completing the following in an EPC role:
- Supply, construction, and commissioning of the full water plant
- Project management and procurement (EPC role)
- Detailed design
- A portion of the process design
- Full electrical design
Current Progress of the Project
This drinking water treatment plant project is a 30-month contract. Currently, WEC Projects is working alongside Bergstan for the engineering phase. On completion of the initial basic design, the WEC Projects engineering team will move into a detailed mechanical and electrical design process.
Future Targets of the Project
It is forecast that WEC Projects will move onto site in 9 to 12 months from now to start the mechanical and electrical installation. Commissioning will happen thereafter, prior to successful handover to the client.
