I live in Vancouver BC, our drinking water comes essentially from mountain run off and snow melt in two local watersheds. We get less and less every year.

My thought is that with distillation we could use brackish/ river water, then concentrate the brine until it's as salty as ocean water and put it in the ocean.

My thought about sewer outfalls was that adding the brine to the sewer flow should pretty much match the salinity of the source because any volume that goes into the pipes comes out of the sewers. (minus some evaporation).
