Emergency Use

You can operate your SWS-200 solar water still even when there is no pressurized

water. This situation may arise in the event of an emergency like a major

earthquake, or simply when you're in a remote area such as a campsite or on a

boat. Virtually any source of water can work, including seawater or highly

contaminated water.

The source water needs to be elevated above the level of still, in order to create

head pressure. Either a bucket or water-tight bag can be used. You'll need

appropriate fittings to attach to the still. Please contact Do-Right Solar if you need

help with this.

With the exception of seawater, such emergency water is often rather murky, and

for best results it should be pre-filtered before it is run through the still. The reason

for this is that the input manifold of the still has an array of small holes that

distribute the water over the wick. If the water is murky then these holes are apt to

become plugged.

A good way to pre-filter water is with a sand filter. This is simply a bucket that

has layers of sand and gravel, and some pipe fittings. YouTube has many videos

showing how to construct such a sand filter, for example:

If there is enough demand, Do-Right Solar may eventually offer an "Emergency

Kit", consisting of the above items.
