What is siphonic drainage?

Here in the UK, we’re no strangers to spells of bad weather. With rainfall records being broken left, right and centre, it’s now more than ever businesses and homeowners need to protect their premises with appropriate drainage. And with gravity drainage not up to scratch to handle the ever-increasing adverse conditions – people are looking to siphonic roof drainage to handle this. But what is this type of drainage and what are the benefits of it? We’ve explained this for you, here:

Siphonic Drainage explained

Whilst it may sound confusing, the siphonic option is a relatively simple form of drainage. Compared to gravity drainage, which works by relying on gravitational pull for the water to flow down to the lowest point. Letting air and other debris that can be sucked into the pipes too. When debris/air enters a pipe, the drainage becomes less efficient by reducing the drains capacity, which could ultimately lead to blockages.

A siphonic drainage system is fitted with anti-vortex baffle plates which stops anything entering the drainage other than the water. Siphonic drainage will suck the water down at a high speed and with the lack of air, the drainage process is as efficient as possible.

Benefits of siphonic roof system

  • Increased efficiency of drainage – with the pipes full of nothing but water drainage occurs without any clogging or blocking
  • A horizontal collector pipe can be located near the gutter, allowing you to make use of the internal space
  • Reduction in the number of downpipes on your building 
  • No gradient required for horizontal pipework – which helps maximise the potential of the building
  • Quicker draining – water is drained off the roof at a faster rate. In the case of heavy rainfall
