Checklist 4: Seawater Assessment

1. Source Availability

☐ Seawater source available

The location should provide reliable access to seawater throughout the year, including during storms, seasonal changes, and extreme weather conditions.

2. Water Quality Assessment

☐ Raw seawater quality analyzed

Parameters such as salinity, turbidity, temperature, algae concentrations, and potential contaminants should be evaluated before system design begins.

3. Intake Location

☐ Suitable intake location selected

The intake should be positioned to minimize sediment intake, biological growth, pollution risks, and interference from shipping or coastal activities.

4. Desalination Technology

☐ Appropriate desalination process selected

The selected technology, such as reverse osmosis, must be suitable for the local water quality, production capacity, and operational requirements.

5. Energy Supply

☐ Energy requirements evaluated

Desalination requires significant energy. Reliable power supply and long-term operating costs should be assessed during planning.

6. Brine Disposal

☐ Brine management concept developed

Concentrated brine generated during desalination must be disposed of safely to minimize environmental impacts on marine ecosystems.

7. Operational Requirements

☐ Operation and maintenance requirements assessed

Membrane cleaning, equipment maintenance, spare parts availability, and operator training should be considered from the beginning of the project.

8. Economic Feasibility

☐ Long-term costs evaluated

Investment costs, energy consumption, maintenance requirements, and replacement costs should be analyzed to determine overall project feasibility.
