Water streams start on the highest point of the residential area (right beneath the top pool) and go down to the two lowest pools, connecting all four pools together, showing the water flow ‘inside’ the wave. Four water streams create waterfalls over the hole in the middle of the wave. The water stream back is transparent, so people who live beneath the stream can enjoy the calm water flow over their apartments!
