FP McCann’s Precast StormHold™ system was specified for a brand new housing development in Church View, Barnsley.
16 new detached properties, as well as installing the roads and drainage infrastructure are being built on the site.
As part of the drainage scheme, a large off-line attenuation tank is being installed to manage the excess storm water from the site. Consideration was given to a number of tank design options, including fully flexible plastic; however, an FP McCann reinforced precast concrete pipe system was chosen.
Situated in two parallel runs, the tank system comprises 12 DN1800 standard spigot and socket pipes, each 2.5 metres in length and weighing approximately 7.5 tonnes. Additionally, there are four end-cap pipes, two of which have a pre-fabricated precast side entry access point attached for ease of inspection and maintenance. This feature eliminates the need for more costly traditional manhole construction.
Holes have been cored in the inlet end-cap units for DN 600 pipes connected back to the main drainage system via a flow control chamber. The completed system will provide the necessary storm water storage and controlled drainage run-off with the added capacity to handle a 1 in 30 year and 1 in 100 year storm event.
FP McCann’s StormHold™ system offers a complete solution to stormwater management utilising tested, tried and approved large diameter precast concrete reinforced pipe technology. In-house design teams work closely with the client and contractor to ensure the attenuation system meets the engineering specification.
