I think I remember something being attached to the roof, a funnel I think that collected rain water which went through something before being added to whatever water they had. Of course they had normal water running as well but we could use that to make sense of it if you wanted to. When the water company stuff does go under much water would be out and about ready for use. Then we would have to use rain water like in the Walking Dead.
