About SKB
SKB is responsible for managing radioactive waste from Sweden’s nuclear power plants. With a strong commitment to safety, environmental protection and technological excellence, SKB enables long-term, fossil‑free electricity production. As part of their continued development work, SKB required a reliable water supply for a major drilling operation at their coastal site.
Our Delivery
Enwa delivered a fully containerised desalination plant designed to produce process water and general utility water from brackish seawater. The system can provide a capacity of 10 liters per second, supporting the continuous and demanding needs of the drilling project.
Scope of Supply
Our delivery included a complete, modular desalination solution:
- Pump station for seawater intake
- Sand filtration (containerised)
- Reverse Osmosis system (40 ft container)
- Remineralisation and distribution unit (40 ft container)
- CIP unit (20 ft container)
Each container was engineered, built, and pre‑assembled to simplify on‑site installation.
The Challenge: Space Constraints & Harsh Installation Environment
One of the project’s key challenges was placing the pump station directly at the seawater shoreline, an environment demanding robust installation techniques and reliable anchoring.
A second challenge was optimising internal space usage: all components, including tanks and process equipment, had to be integrated into just three 40-foot containers without compromising access for maintenance.
Our Solution: Smart Engineering & Precise Installation
To secure the pump station at the shoreline, Enwa worked with a professional diver who bolted the intake structure to its underwater foundation. This ensured stability despite the challenging marine environment.
Inside the containers, our design team applied their expertise to create a compact yet service-friendly layout. Through intelligent positioning of tanks, pipework and RO equipment, the full desalination process could be accommodated within the available footprint, maintaining both performance and long-term maintainability.
