How much of municipal water needs to be fresh water?
Like if you showered with salt water, bathed in salt water, flushed your toilet with salt water etc. Then you wouldn't need to desalinate so much. So maybe, tap salt water could be viable for apartments. Then you'd have to have some domestic desalinator for those few liter's per day you actually drink. Well or buy bottled water.
Now that I think of it: Maybe you could make the hot water salt, and the cold water fresh. You aren't supposed to drink hot water anyway since it contains more dissolved nasties. And you wouldn't water your lawn with hot water because that would be like super wasteful. Although I can see how hot salt water could be somewhat corrosive so maybe you'd need to switch up the plumbing at a huge cost.
- rpenm 12y agoAdding a separate salt water supply infrastructure would be expensive. Salt water is also quite corrosive; pipes, fittings and fixtures would have to be designed/tested for such use. Besides, having my clothes, dishes and body perpetually crusted in salt is not appealing. You'd be better off subsidizing grey water systems. Or better yet, focusing on larger scale inefficiencies in agriculture. Or push for market-pricing so individuals/businesses have incentive to pursue efficiencies.
