What do you think the average cost per gallon is to treat wastewater?

I can’t speak for other communities, but in Portland the cost is just $0.01 per gallon. The actual cost probably varies based on construction or upgrade needs. As for water use, that really varies depending on the consumer. Some folks water their lawns here. Others just let them turn brown when the weather heats up a little. We’ve averaged out our average consumer generation to be about 100 gallons of wastewater per day.
