Technical Feature


when required, the chamber also featured a penstock flow control.


Over 500m of pipe runs in 2100mm diameters were supplied. The technical team design engineered the pipe to ring stiffness SN2 to meet ground conditions, burial depths, native soil pressures and loading on-site. The system was tested to pass required deformation and buckling checks in accordance with BS EN 1295-1.


To accompany the pipe runs, the bespoke system incorporated 34 pre-fabricated modularised fittings which included 90o bends and ‘F’, ‘T’ and double ‘T’ fittings to fit the limited on-site dimensions perfectly.


The socket and spigot nature of these engineered fittings kept jointing to a minimum, allowing for easy pipe alignment and speedy installation using electrofusion jointing. This in turn significantly reduced on-site installation time and cost.


A total of 10 access manholes were also supplied in 1200mm and 1800mm diameters, to make maintenance work safer and less strenuous for installers needing pipeline access.


Helping the construction industry evolve


All of these examples demonstrate pioneering ways in which plastic manholes and associated pipes are helping to transform standard site procedures in the construction industry, safely and effectively. Their growing use across the UK reflects the increasing awareness that plastic is often the best product for the application.


Today, more than ever, developers, local 46 drain TRADER | April 2018 |


authorities and house-builders are seeking high quality, sustainable products and long-term solutions with low environmental impact, responsibly sourced and safe and easy to handle on site. Plastic manholes from BPF Pipes Group manufacturers offer an effective and efficient solution.


The BPF Pipes Group and its members have welcomed the inclusion of plastic manholes in the new draft SFA8, which reflects their growing acceptance by the UK water industry as a good quality solution for the modern sewerage network.
