Water lines

QR_BBPOST Nothing wrong with lake water intake as long as you are in fresh water. The last 3 boats I had were lake water drawn from the factory and most are in my area. Never heard of an issue. I believe the only boats that draw from the potable water tank are those set up for salt water use as in equipped with heat exchangers.

I think it depends on where you're at in the fresh water. If you are in a smaller lake or one that gets warm, then algae can definitely be an issue. If you're in a cooler lake or on/near a river one that flows and prevents the growth of algae then it might not be much of an issue. A lot of the marinas around us it can make a difference if you're near the entrance to the marina (close to the lake) or in the back where there's more stagnant waters.

This looks like a compelling system for treating raw water and the lines to/from the toilet:
