Storm sewer first for NI Water
Polypipe Ulster reveals how it helped Northern Ireland Water (NIW) install storm sewer technology in Dundonald
Plastic drainage specialist, Polypipe, has helped deliver a unique drainage solution for Northern Ireland Water’s Carrowreagh Storm Sewer Improvement Scheme in Dundonald, near Belfast. An attenuation tank, created from Polypipe’s Polystorm-R and Ridgistorm-XL products, forms an important feature of the £600,000 essential storm water improvement works, which are being carried out in response to flooding in a residential area and to meet future Rivers Agency standards.
Selected following a competitive tender process, Polypipe’s technical team worked closely with Northern Ireland Water, specialist installers Charcon Construction Solutions and main contractor Graham Construction to devise a bespoke, easy-to-install modular storage tank to the exacting volumes required, complete with a number of two-part access chambers to aid future inspection of the structure.
Polypipe says this is the first time a sustainable urban drainage system (SuDS) of this kind has been used by NIW and was chosen for its ability to deliver more efficient environmentally friendly processes, and speed up the construction of the storm tank over more traditional materials. The Polypipe team was able to create bespoke 900mm Ridgistorm-XL outlet pipes with 300mm connections to the storm tank, as an innovative, lightweight alternative to existing concrete piping.
Keith Haslett, head of wastewater networks procurement at NIW says: “The new modular storage tank is a unique sustainable drainage system and this is the first time this technology has been used by NI Water.
“The success of this pilot project has been greatly assisted by the experience of the water management specialists at Polypipe, NIW Consultant White Young & Green and our framework contractor Graham Construction. Work is progressing very well and we
anticipate the project will be completed by October 2012.”
Harry Shields, sales director at Polypipe Ulster, adds: “The scheme is a great example of the bespoke design solutions which can be achieved when manufacturers, consultant engineers and contractors work together from the early design stage and we are delighted to have been selected for this project.”
The six month project will also reduce risk of flooding from the nearby Enler River. nnn
