[Also in Division F1] In a theatrical water apparatus having a weir tank 4 at a high level so that water flowing over the weir is directed towards the main tank 8 and means 9, 12 for recirculating the water, the weir tank is mounted on a wheeled vertical supporting structure 1 which has a forwardly and upwardly extending water receptacle pivoted to the bottom of the supporting structure so as to direct the water back to the main tank 8. Water is drawn from the main tank 8, made up of bolted sections, through pipe 9 by a pump 10 driven by an electric motor 11, and delivered through pipe 12 to weir tank 4 which has an internal baffle 13. The front of the supporting structure is covered by a waterproof canvas covered plywood sheet having fibre-glass rock-simulating formations 6 which provide cascades 7 when water spills from outlet 14. Receptacle 15 has a transparent front edge, a waterproof canvas lining and fibre-glass simulated rocks 8 and is hinged at 16 and supported by a hinged strut 17. Water flows out of receptacle 15 and through receptacle 19 via a waterproof canvas tube 20 into main tank 8.
