A SUSTAINABLE APPROACH TO SOLVING FLOOD RISKS WITH HYDROPLANTER Cwmbach, is a village near Aberdare in the county of Rhondda Cynon Taf, South Wales, has the meaning “Little Valley” in Welsh (Cwm = valley, Bach = little). With an approximate population of 5,000, the area is mostly known for its substantial coal mining industry, Known for its steep topography and higher elevations to the East, the Afon Cynon river borders the West draining to the Aberdare canal – which is the main river that runs through Cwmbach, discharging just south of the train station. With this in mind a detailed Flood Risk Management plan was set out by Rhondda Cynon Taf C.B.C in November 2015, highlighting all areas with low to medium to high risk.
HydroPlanter is modular and can be extended to suit specific needs.
Notable high flood risk was at the conjunction of Cwymbach Road and Canal Road with concerns to properties adjacent to the highway at flood risk. In June 2020, GreenBlue Urban was delighted to support the engineering team at Aecom Cardiff for the SuDS design to elevate flood risk to the area. It became apparent that the recently launched HydroPlanter modular rain garden system would be the perfect mitigation solution.
The “plug and play’ sustainable urban drainage solution can attenuate and cleanse stormwater and provide amenity and biodiversity to new and existing spaces. The modules will be filled with a particular soil specification and planted with wildflowers and biodiverse grasses.
The “plug and play’ sustainable urban drainage solution can attenuate and cleanse stormwater and provide amenity and biodiversity to new and existing spaces. The modules will be filled with a particular soil specification and planted with wildflowers and biodiverse grasses. The modular characteristics with pre-calculated hydrological performance statistics mean that specification and design is very simple for any given catchment area. GreenBlue were pleased to support Scott Parnell with their winning tender to supply, 6, Starter and End modules, 18 continuation modules along supporting weir walls. Perforated pipe and RootRain Civic inlets T’s with downpipe. Drainage stone and of course our dedicated SuDS ArborSoil Hydro.
