AN INCREASE IN THE NUMBER OF TALL BUILDINGS THROUGH CITY GROWTH LIMITS THE SPACE AVAILABLE FOR SUFFICIENT WATER DRAINAGE. ADAM TURK – COMMERCIAL DIRECTOR AT POLYPIPE – EXPLAINS HOW MODERN WATER MANAGEMENT SOLUTIONS AIM TO ALLEVIATE THIS


SMART WATER FOR SMART CITIES


C


onstruction activity in major cities is on the up, with recent reports stating that the waiting time for cranes and lifting equipment on some London projects is up


to 26 weeks, whilst construction in the Big Apple has surged back to life, with $20.5 billion worth of new construction starts in in the city during 2012. With much of global growth to come from


cities, a number of considerations need to be made – such as the provision of suitable drainage. Extreme rainfall events, such as those experienced in the UK in recent winters, are becoming a more regular occurrence across the world, thanks in no small part to climate change. In response to this, many governments have


introduced legislation that aims to identify new ways to manage surface water via drainage systems, but the challenges are compounded in cities by the lack of available green space for the absorption of water, with the majority of ground level covered in tarmac for roads or taken up by buildings. In new cities, however, the possibility exists to make space for water and solutions can be integrated at the planning stage to avoid the issues

currently faced by some global conurbations. British manufacturers of water management


solutions have responded to the threat of extreme rainfall events by developing a breadth of intelligently engineered products that work to store and attenuate surface water, allowing it to drain away at source and be dispersed into local sewerage systems without overwhelming them. However, while a variety of these drainage


solutions exist to meet the needs of commercial and residential developments, they often utilise the space available around the building structure to allow for the provision of below ground attenuation tanks. In built-up city environments the luxury of this additional space is often not available due to the proximity of neighbouring developments, with the building’s footprint sometimes providing the only space in which to work. Projects such as this call for an alternative approach to be taken. At Polypipe we’ve worked to combat this issue


through the introduction of our Permavoid Podium Deck geocellular solution. Consisting of lightweight, robust modular cells that can be interlocked to create a load supporting raft
