The TRAP has been developed as an inline sampling device to identify the source of high risk items that could cause blockages in sewers. In addition, The TRAP can be used as a deployment platform for a number of different sensors into harsh sewer environments. This will enable the asset owner to extract important information on the operating conditions of their sewer network.
The TRAP is designed to be left in place for a pre-determined amount of time, after which point the asset owner can remove the device and inspect the contents. Targeted awareness campaigns can then carried out with the local inhabitants. The TRAP is designed not to contribute to the cause of the blockage if it is left in longer than expected.
As a secondary use, TRAP can be used as a collection device for debris displaced upstream during the cleansing process.
