The idea of Sustainable Urban Drainage Systems (SuDS) has been around for over 20 years but has received mixed consideration and implementation across the United Kingdom and Ireland. However, changes to various planning regulations over the last number of years have gradually seen designers and developers, as well as local authorities, more open to consideration of SuDS as representative of the sustainable engineering management of surface water runoff.
With the latest changes to the planning regulations in England in 2015 and the publication of the revised SuDS Manual from CIRIA (C753), it is safe to say that sustainable design is here to stay.
Those in relevant sectors of the construction industry need to ensure they are fully informed of the latest techniques and products on offer as they seek to design for reliable, long-term and cost-effective surface runoff control.
The Checkmate inline check valve from Tideflex is an ideal device for backflow prevention in a SuDS scheme. It is unobtrusive, low maintenance and long-lasting, effectively fading into the background of an aesthetic design. It also offers odour abatement and protection from rodents (and even children) accessing the piped portion of the system in designs where pipes are more likely to be accessible than in traditional systems.
Rubber construction - flexible, durable & strong
Low cracking pressure
Located inside the pipe / ends flush with the headwall
Do not warp, freeze or corrode so maintain long-term function
No areas or parts that trap or snag debris
Unobtrusive & easy to fit
No maintenance - saving operational time and money
25+ years service life - long-term capital cost savings
Reliable, proven track record - no unpleasant surprises
Drains and self-clears in relatively flat designs - ideal for meandering low-flows
Aesthetically appealing in landscaped areas - doesn't protrude
CheckMate valves can successfully be used in SuDS schemes in parks and close to playgrounds and footpaths. Below are some photos of their installation in these scenarios.
