Thorne Rainwater Systems are one of the UK leaders in Siphonic Roof Drainage Systems.
Our highly motivated team are fast to react to new building demands.
Our company has invaluable skills to cope with any project challenges.
SIPHONICS VERSUS TRADITIONAL ROOFING
In principle, siphonic drainage is a very simple process. Unlike traditional roof drainage, which is designed to flow part full, a siphonic system operates at full capacity, when water is sucked or siphoned from the roof down into the drain at high velocity.
Traditionally, the rainwater is collected from the roof at regular points by gravity flow. The larger the roof area is, the more numerous the points are. The risk of overloading can be an issue with large areas of drain run-off water from building roofs.
WORKING WITH LEADING PROFESSIONALS
Why use siphonics
Several factors have to be considered to make siphonic rainwater system work effectively. Specially designed roof outlets take into account rainfall intensity rate and to design the pipework configuration to optimise performance.
Rainwater can be easily routed to collection tanks for future recycling, e.g. rainwater harvesting, irrigation, fire ponds, etc.
You can talk to us direct or arrange your architect or contractor to organise the first phase meeting to discuss future project requirements.
The drainage system is suitable for a multitude of applications in industry or laboratories. The polyethylene used is resistant against most standard alkalis, acids and chemicals, as well as hot water up to 80 °C.
The polyethylene used contains special additives which effectively protect against UV rays. The weatherproof pipes can therefore be stored outdoors for months. The pipes and fittings withstand shocks, drops, impacts or short-term pressure without breakage or permanent deformation.
Land can be expensive. therefore a more compact system, with simple and rapid installation, is an advantage. The hydraulically optimised geometry of the fittings ensures a high discharge capacity in the drainage system and allows both an economical dimensioning of the pipes as well as a space-saving configuration of the pipe ducts.
