UKPN Works With Green Rhino to Develop Roadside Dewatering Filters

A new filter bag has been developed in partnership with the UK Power Networks Environment Team and a consultancy called Capture Green. The introduction of the Green Rhino has prevented any potential for localised pollution by fitting over the pumps discharge pipe and capturing any silt and contaminant residue. After a successful trial of the system it is now standard. UK Power Networks are leading best practice in this area being the first utility to adopt this filtering process.

Green Rhino Technology Part of UKPN Innovation Strategy

Green Rhino® technology is being deployed by UK Power Networks on street-works to benefit the company, our customers, and the environment. Before the introduction of the Green Rhino it was accepted practice to pump water out of a street-works hole and discharge to a grass verge, if available, or down the street if not. If the water was heavily contaminated with oil and/or sediment, the company would have to arrange for a tanker to pump out the water and take it off site for disposal at a cost of approximately £1,000. UK Power Networks worked closely with Capture Green to develop the Green Rhino, an oil and sediment filter, for use when dewatering small excavations prior to undertaking work. The Green Rhino prevents the need to tanker away lightly contaminated water and also ensures any water that is pumped is clean. A Green Rhino bag costs £150 and is re-usable, with the technology subsequently having been adopted by other DNOs and in the gas, water and telecommunications sectors.
