Key site assessment activities
A thorough site assessment ensures the chosen desalination solution matches local conditions. Essential steps include:
- Solar resource analysis: Measure or model solar irradiance to size PV or thermal collectors accurately.
- Water source testing: Analyze feedwater for salinity, turbidity, organics, heavy metals, and biological contaminants to define pre-treatment needs.
- Demand assessment: Estimate daily and seasonal water demand to size storage and production capacity.
- Space and logistical assessment: Evaluate available land or rooftop area, access for equipment delivery, and security.
- Environmental and regulatory review: Check permits, protected areas, and local discharge rules for brine.
- Infrastructure and grid access: Determine availability of grid power, roads, and communication networks for remote monitoring.
Additional considerations:
- Community engagement: Understand user willingness to pay, operating capacity, and local technical skills.
- Brine disposal options: Identify feasible pathways (sea diffuser, evaporation, injection) and environmental safeguards.
A well-documented site assessment reduces risks, enables accurate cost estimates, and informs system selection and operation planning.
