England’s best kept SUDS secret A pioneering drainage scheme on a Hampshire housing development was only made possible by 18 of the country’s best-kept SUDS secrets. The 1900-home Elvetham Heath develop- ment at Fleet is featured in the govern- ment’s seminal Response to the Pitt Review, the forerunner of the Flood and Water Management Act. But the report does not point out that it is the
performance of 18 Hydro-Brake® Flow Control devices, from Hydro International,
that enables the SUDS scheme to operate successfully. Ryan Lundy, senior civil engineer for Bradbrook Consulting worked on the design: “The strategically placed Hydro-Brake®
Flow Controls provide balancing and buffering of the surface water run
off. Across the whole site the run-off is regulated by gravity and the storm water drainage strategy is achieved without the use of pump stations.”

Launch of enhanced construction details for
EPS insulation The UK EPS (expanded polystyrene) industry has launched a comprehensive set of enhanced construction details, which have been endorsed by the Energy Saving Trust (EST) and developed with the support of BRE. The EST enhanced details are now becoming available from accredited EPS group members listed on the group’s website and are designed to ensure building professionals are able to achieve the highest levels of insulation performance as well as full com- pliance with Building Regulations when specifying EPS insulation in masonry build projects. The details give architects, building design and construction com- panies the guidance needed to determine optimum installation and thickness specifications to achieve the highest insulation levels. Stephen Passmore of the Energy Saving Trust said, “This comprehensive set of enhanced details is an important contribution towards helping UK construction projects achieve even higher levels of thermal resistance in building design and construction. The CO2 savings are potentially substantial.”
Styrofoam-wrapped building wins award An office building featuring Styrofoam-A insulation from Dow Building Solutions has won ‘Best Sustainable Development’ in the prestigious LABC Construction Excellence awards scheme. The office is part of the new Carbon Neutral Business Zone (CaNeBuZo) in Lincolnshire, designed by Dr. Jeremy Harrall of SEArch Architects with Local Authority Building Control services provided by South
Holland District Council. “Styrofoam-A sits perfectly within the concept of the CaNeBuZo development as it’s ideal for external use where moisture resistance and strength are key,” said Jayne Law, UK and Ireland sales manager for Dow Building Solutions. “This is making it very popular with designers of earth-shel- tered, zero carbon schemes such as CaNeBuZo as well as Passivhaus design, where wrapping structures in external insulation helps reduce thermal bridges.”

WPL and Soma Services supply National Trust
WPL Ltd and Soma Services were appointed by the National Trust to provide solutions for their wastewater management needs at Fountains Abbey, a World Heritage Site in North Yorkshire. An increase in visitor numbers and tighter stan- dards forecast by the Environment Agency meant that existing systems needed to be upgraded or replaced in three different locations. WPL HiPAFS were the chosen solution and were individually designed to meet the specific needs of each location. On land adjacent to the Fountains Abbey West Gate, a system was in place to treat foul flow from toilets and the visitor centre restaurant. The existing system, although old, was in good mechanical order and utilising this equipment as part of the new scheme offered substantial savings. A WPL HiPAF biozone/humus module was selected to operate in series with the existing unit. Ongoing sampling has shown that the upgraded works provides full nitrifica- tion as well as compliance with the consented standards, and it has been cal- culated that the system can deal with a significant increase in visitor numbers. A WPL HiPAF was also installed at a holiday cottage development on the Estate. A carefully designed soakaway system followed the contours of the site allow- ing the highly treated effluent to be dispersed into the ground, eliminating the risk of adverse environmental impact on the site.
