Syphonic drainage specialist Fullflow has recently completed the design, manufacture and installation of a drainage system for the new college building at Stroud College in Gloucestershire. The roof area of over 4000m required a flexible system which could remove rainwater efficiently from the roof without compromising the aesthetic appeal of the building. The chosen system's ability to route pipework horizontally combined with the reduction in downpipe quantity and diameter size provided the architect with greater flexibility. The college's drainage system was designed for the maximum rainfall intensity of 108mm/hr and required only four downpipes to remove approximately 112 l/s of rainwater.

Syphonic drainage from Fullflow has been installed at the new Terminal Building in Farnborough Airport, Hampshire. The system was required to remove rainwater efficiently from the RIBA award winning building which features a wing-shaped design and an aluminium shingle clad exterior. A solution that did not compromise the aesthetics of the building, the syphonic system provided fewer downpipes, and a smaller diameter than traditional drainage systems. The system is designed for the maximum likely rainfall to occur over a 40 years period, with eighteen rainwater outlets and two downpipes installed, draining 104 l/s.

Syphonic drainage from Fullflow has been installed at the Savill Garden visitor centre within Windsor Great Park, London. Designed by Glenn Howells architects, the structure has an undulating leaf shaped roof which is nearly 100m in length and constructed from larch. It is clad with green oak from The Crown Estate's own sustainable sources in the Windsor Estate. The drainage system was designed for the maximum potential rainfall that could occur over a 37.5 year long period. This was achieved with only ten rainwater outlets and four downpipes, draining 2000m at a flow rate of 100 litres per second.

Draining rainwater from a 160,000m? roof area, a self-priming syphonic system from Fullflow is in use at Madrid's Barajas Airport. Some 72 down pipes have been installed to cope with up to 150mm of rain per hour. To maintain aesthetic integrity, the syphonic system components were made from stainless steel. The self-priming action draws water off the roof quickly.
