Abstract: A connection system comprises a connector and a pipe. The pipe is made from a hydrophilic membrane capable of pervaporating brackish water or such like as substantially pure water, such as Dutyion™. One feature of this material is that it expands significantly as it hydrates. The pipe is generally cylindrical, but it is corrugated along its length, with roughly regular ridges and grooves.
