Sustainable drainage and water management manufacturer Polypipe has launched a new gully chute for use in highway applications designed to reduce the risk of blockages.
It said Ridgichute allows captured water and sediment from high-risk carriageways to pass straight through into its Ridgidrain drainage system, preventing surface flooding.
The sumpless design aims to reduce the risk to roadside workers by preventing blockages caused by silt accumulation. Captured water, silt and sediment are carried into a chamber to the side of the carriageway, where lower risk maintenance can take place.
Ridgichute gully chutes are manufactured from lightweight polypropylene and designed to fit seamlessly with the firm’s HAPAS-approved Ridgidrain popular surface water drainage piping system for use on highways projects.
Three sizes are available, each with the choice of either a 225mm or 300mm outlet:
These sizes have been designed in accordance with the most widely-used gully gratings that will be installed above the Ridgichute.
Sean Norris, product manager at Polypipe, said: ‘The introduction of the Ridgichute is a great addition to our comprehensive range of surface water drainage solutions for road projects. The main benefit of a sumpless design is to eliminate the need for maintenance and cleaning activities on high-risk carriageways. This also removes the need for the carriageway to be closed, allowing traffic to remain free flowing.
‘Unlike a traditional gully, any sediment will be carried down the piping system and collected by, for example, a RIDGISTORM Separate chamber located off the carriageway, for safer maintenance activities to commence.’
