I’ve attached a few photos of different styles of stone rill we have made for water play spaces. One rill, at home, was simply ground out of the stone to create a smooth, shallow depression across the patio (much to Helen’s delight!) and several others involving either staggering the paving, laying sets to create a channel or deeper carving of the stone.
I am often asked if the stone becomes slippery after time, surprisingly its never been an issue, however if the water play rill was uses an lot it may be necessary to give it a blast with a jet wash now and then. I really enjoy installing these water play features in private gardens and school playgrounds, I was lucky enough to have parents that would allow me to run the hose pipe for hours while making rivers and dams through the neighbouring woodland so know just how much fun playing with water can be. These days I encourage people to use rain water or recycle the water with either a hand pump or electric pump.
The smooth channel running across our patio at Copper Beech central. The water is fed from a large rain water storage tank at the back of the house. Our boys 9 and 11yrs still love to play in this on sunny days and little Anna 1.5yrs finds sitting in it to be delightful, especially just as we are about to go out!
With the slate paving set slightly apart we were able to make this small water play rill that again runs from a rain water tank and ends up running into a large sandpit.
As part of a water play space installed at a school in Nuneaton this stone set on edge created a very textured surface, we were able to create a channel that ran around the edge of the circular play area.
Cut into flagstones this rill could be made any length, the channel is about 10mm deep and the surface is quite textured making lovely ripples and an extra non-slip surface.
