2. Seawater Reverse Osmosis (SWRO) Process power is from the ADC’s demonstration facility at the “most affordable point” and for the SWRO process only. This includes the power of the main HP pump and PX booster pump only with no allowance for intake, pre-filtration, conveyance or distribution.

3. WBMWD Total Power includes intake, pre-filtration, SWRO Process, conveyance and distribution power for their proposed 20 MGD ocean desalination facility.
