Stormwater Solution for Houghton Regis Residential Development

Renowned developers, Taylor Wimpey, called upon Polypipe to provide an engineered drainage solution, designed to work with a sloping gradient found on site. Set in the countryside town of Houghton Regis, the Regent's Place large-scale residential development comprises of a mix of 180 two, three and four bedroom houses nestled in a tranquil area that offers stunning views of the lanscape.

The landscape surrounding the Regent's Place development features a larhe public open space with limited footprint for drainage design and sloping gradients. Taking on the challenge, Polypipe worked closely with Taylor Wimpey and Consultant Engineers JPP Consulting, to design a stormwater solution, incorporating staggered legs to take site conditions into account, that also met site requirements and adopted elements laid out under Section 104 agreement for approving water company, Anglian Water.

"The attenuation tank supplied for Regent's Place project boasts a 3m diameter offset RIDGISTORMCheck Vortex Flow Control Chamber which controls discharge water from the tank at an agreed rate of 10l/s, so the local watercourse is not overwhelmed. To control additioonal flow when required, the chamber also feature a penstock flow control"

Polypipe supplied over 500m of Ridgistorm-XL to form 14 pipe runs in 2100mm diameters, Polypipes technical team engineered and designed the pipe to ring stiffness SN2 to meet the 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 Ridgistorm-XL system incorporated 34 pre-fabricated modularised 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 electro-fusion jointing. This in turn significantly reduced on-site installation time and costs.

Polypipe has worked on many residentail projects in the past and understand the implications surrounding routine maintanence work. In order to make maintanence work less strenuous and overall safer for installers, Polypipe also supplied x10 RIDGISRORMAccess Manholes in diameters 1200mm and 1800mm. The manhole access assists workmen by providing easy access to a pipeline.

"Polypipe designed the required stormwater attenuation system to not only fit the available are, but also saved us time and costs on the installation by delievering the system and fittings as one piece modular units ready to install"
