I have also been making this for Tranmoor Primary in Doncaster. They wanted a water wall for their Reception yard. We decided I would make a basic structure from timber and recycled plastic lumber from www.kedel.co.uk . A series of brackets have been made that slot into the main structure. these can be moved around, and have a variety of sizes of holes cut into them. This means a variety of pipes and gutters can be fitted by the children. Holes have been positioned in the wall to encourage to work together and communicate- to play collaboratively.It s fantastic when you have an idea in your head of how something will be used, and the children use it in a completely different way! Ill be back at the school later in the year to see what developments can be made.
