This is a prototype for an 8000 litre pond bladder, manufactured in Adelaide at a cost of AUS$348 using 0.75 mm flexible polypropylene. The bladder is used to store potable water at the bottom of a farm pond where the pond liner is also made from flexible polypropylene. The bladder should have access to clean rainwater, for example, runoff from the rooves of nearby structures. The potable water in the bladder is isolated from the dirty water in the pond.

Because the pond bladder is submerged in the water in the pond, the structural forces on the bladder are minimal, regardless of the volume of stored potable water. As the size of the bladder inceases, this becomes the cheapest way to store potable water. This concept has the potential to provide affordable drinking water for millions of Africans.

This invention is in the public domain and I am looking for someone to take the concept to the next stage. More information is avaiable from the pond bladder page at the Measured Irrigation website
