Leeds-based ground worker and civil engineering group Howard Civil Engineering is undertaking the complete package of works on a brand-new housing development at Church View in Barnsley, South Yorkshire.

Working in partnership with sister company Erris Homes, the group is building 16 new detached properties, as well as installing the roads and drainage infrastructure on site.

FP McCann tanks case study 2As 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, Howard CE opted for an FP McCann reinforced precast concrete pipe system.

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.

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.

Speaking of the precast pipe tank design, Andrew Rafton, Howard Civil Engineering’s Quality and SHE Manager says: “We have worked very closely with the FP McCann drainage designers at their Ellistown production facility to establish the most efficient and cost-effective attenuation system to match the site’s drainage requirements.

“Precast concrete pipes are simple to install and have a proven track record of performing in below ground drainage and attenuation structures. Additionally, we were able to incorporate a class ‘B’ bedding design into the tank build, further reducing the costs of the project”.

FP McCann tanks case study 4FP McCann’s StormHoldTM 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.
