West Siphonics are siphonic roof drainage specialists providing a one-stop solution for design, manufacture, installation and project management of the most advanced siphonic roof drainage systems to cater for today’s ever-changing climate. We have a new advert being published in the February publication of the Construction Forum Magazine, which you can see below. The advert shows one of the latest products that we produce, improving the drainage services that we offer to our customers.
This impressive site contains a 1,000,000 square foot warehouse and a multi-storey staff car park. The main warehouse roof consists of 2 eaves gutters & 14 valley gutters, the roof is also hip ended. The total roof area is approximately 91,950 m2, based on the specified rainfall intensity and geographical location of the project, this equates to a staggering 5,300 litres of rainwater per second falling onto the warehouse roof during peak storm conditions.
Due to the vast amount of water on the warehouse roof and external yard area, your typical surface water underground drainage network would simply not suffice. Therefore, approximately 1.5 Kilometres of Ø2800mm (yes, 2.8-metre diameter pipe!) was installed underground around the full perimeter of the warehouse to cope with the extreme volume of water.
The Siphonic roof drainage consists of primary & secondary systems. On a typical project, the secondary systems would discharge 500mm above external FFL onto hardstanding. On this occasion West Siphonics was asked to run the secondary systems underground alongside the primary systems into the underground drainage network – this was due to the external yard drainage being unable to cope with the potentially high volume of water being discharged onto it. In some cases, the Ø2800mm underground pipework is over 40 metres away from the perimeter of the building. We were able to build this into our Siphonic calculations which meant our pipework could run fully Siphonic all the way out to the discharge point, negating the need for a fall on the pipework as would be necessary with a traditional gravity-fed pipe.
West Siphonics produced 3D Revit models as per the project BIM requirements and attended several coordination/clash detection meetings to ensure our systems were fully co-ordinated with other services prior to our start on site.
In conclusion, West Siphonics are very proud to be a part of this prestigious project. We are happy to report that our site installation teams are progressing well on-site and are on target to hit programme.
Vaccines Manufacturing and Innovation Centre (VMIC)
West Siphonics has been selected to develop the Siphonic Roof drainage scheme for the new Vaccines Manufacturing Centre in Didcot, Oxford. This state-of-the-art building will benefit from our industry leading design with both Primary and Secondary siphonic rainwater drainage systems offering the greatest protection to the building and its invaluable contents. West Siphonics will Design, Manufacture and install 1400m of pipework to drain a total of 410 litres per second from the roof.
The rapid acceleration of this 7000 square-metre building due to the current Covid -19 pandemic means the doors will now open 12 months ahead of the scheduled date in 2022. Works began on the site at the Harwell Campus in early April, West Siphonics will commence with the installation of the systems in July.
It’s that time of year again – Audit time! We have just had our annual audits from BBA and CFA covering our Hydrostorm 75 Siphonic Roof Drainage System, and our ISO 9001:2015 Quality Management System & ISO 14001:2015 Environmental Management System.
All are essential to our core business as we view a BBA Agrement Certificate as a mark of excellence based on rigorous National and European standards that validate a construction product’s specialist capability, giving our clients confidence in our on-going commitment to quality and performance.
Similarly, we view our ISO QM & EM systems as much more than just a piece of paper we stick in a drawer every year until the Auditors come around. We utilise fully the relevant management and environmental procedures in the daily running of our business to ensure quality and traceability throughout. That way, when the Auditors appear, we don’t have to change a thing to impress them – we just keep doing what we always do!
A new face in the Scottish office – CAD Designer Bryan Mackie. Bryan is the brother of one of our installers, Scott, who has been with the team for the past 3 years. Bryan brings with him several years of design engineering and draughting experience from the renewable energy and utility industries and it has been a bit of an eye opener. He said,
“I never fully appreciated the significant importance of roof drainage before, but I find it both challenging and rewarding to apply my earlier experiences to the designing of siphonic roof drainage systems.”
West Siphonics recently upgraded Constructionline Membership from Silver to Gold in our continued drive to promote the values of sound Health & Safety practice throughout our workforce and commitment to our partners in construction.
We are proud to continue our sponsorship of the Wickersley Youth Football Team for a third successive season. The lads have now progressed to the U-14 League, and we hope our support can assist them in having a healthy and successful season following what will be without doubt the shortest season they’ll ever have in their footballing careers.
