After many rigorous manufacturing and installation tests, Severn Trent has joined other water companies and given its seal of approval to Stanton Bonna’s elliptical concrete drainage pipes for use in adoptable sewers. The pipes can be used for sewers, drainage or attenuation tanks and can be installed in either a vertical orientation or as shown here, in a horizontal orientation. With a captive gasket joint for rapid installation and ex-stock availability, elliptical pipes are fast becoming a product of preference for specifiers and contractors alike. The versatility of the pipe is demonstrated here as it is installed under a gas main, with minimal depth of cover under traffic loading and at a shallow gradient while still delivering improved flow rates and self cleansing velocities.
