Sports club turns elements to its advantage

The current external development of the historic Roehampton Club in southwest London is doing much more than improve clubhouse and sports facilities and create a new gatehouse and roadways – the club is being both floodproofed and equipped with rainwater harvesting to water its 6065 yard parkland golf course.

Lying on blue clay down from Richmond Park, the Club is a prime site for rainwater run-off. But thanks to the installation of a new drainage system centred on two galvanised steel Tubosider tanks, one for stormwater attenuation and one for rainwater harvesting, the elements are instead providing cold clean water to the golf course.

The project is managed by Mellersh and Harding Consultancy LLP, with Kier Wallis as main contractor and structural engineers Barnard & Associates responsible for technical issues such as drainage. Given the large water storage required and the need for a highly manageable and quickly installed system, Barnard’s investigations showed Tubosider to be the best technical and cost-beneficial solution – a choice they now intend to repeat on other projects.

“We looked at different configurations to be able to keep the harvested water longest on the course, and finally specified a 4380 m³ (near 155000 cu ft) multi-leg attenuation tank of 2.2m diameter pipes, compactly delivered in pre-formed sections nesting with the 400 m³ harvesting tank,” says Barnard’s David Purcell.

Despite having to follow a non-continuous programme for the project, and the backfill delayed to allow for final client decisions, all the sections have been fitted without fuss – providing a fully workable floodwater and harvesting solution, confirms Kier Wallis project manager Andy Jennings.

“We have also used a Tubosider system on nearby Rosslyn Park rugby club, and the ability to inspect their tanks via a manhole is a major plus,” he says. “Pipes as large as these make it easy to access any part of them and check and maintain their performance.”
