Project undertaken on behalf of the Environment Agency – Thames Region which comprised the Supply, Construction, Installation and Commissioning of 9 River Level Monitoring Stations, 4 x DL7151 with Submersible Transmitters 3 x DL4151 with Submersible Transmitters and 1 DL7141 with Shaft Encoder.
Pre-fabricated GRP Stilling Well sumps were utilised with 300mm Twinwall Risers to ground level with a pre-cast slab complete with Dipping Porthole and EA Benchmark.
Where GRP sumps were impractical or alternative means of mounting tubes were available galvanised tubes were utilised secured to the walls of the structures.
Similarly Gaugeboards were either of the driven T Iron types or wall mounting.
