The dew water was brown because here it is very dusty in the dry season. Everything is covered with a fine layer of dust and the dew forms on top of it. You come along with a rag and wipe it up.

I ran it through my home-made filter but it didn't clean it up too much. The water collected from the tent was two shades less brown.

This is a skill you can practice anywhere that dew forms. Try it sometime. I was surprised by the amount of water that I was able to collect in short order.

I must admit that I wasn't actually drinking the stuff. I had carried in five liters of water and measaured my consumption against my production. I drank 4 liters of water in the 24 hours I was there. I produced about 2 liters. I figure I would have survived on 2 liters per day if I kept activity to a minimum and stayed out fo the sun. Mac
