The site, owned by Rolls Royce, spans 150 acres and will benefit from a new road network, up to 900,000 square feet of employment space, a school, warehouses and 900 new homes, when the £250 million renovation is completed by scheme developer, Muse.
For the sewer system, Polypipe CGU supplied 340 metres of 150mm Polysewer and 250 metres of 450-6000mm Ridgisewer, which were installed for both surface water and foul sewers adoption by the local water company under Section 104 and Section 106 agreements. Over 80 Ridgigullies were also installed to capture surface water. These were connected to Ridgidrain pipes to direct surface water to local natural watercourses. To complete the system, Connection Saddles were installed, linking smaller Polysewer pipes to Ridgisewer, and Ridgidrain to Ridgistorm-XL.
Assisting with surface water discharge on land assigned for homes, Polysewer and Ridgisewer structured wall sewer pipes and fittings were supplied to work in conjunction with the surface water drainage system, Ridgidrain. The drainage systems were connected together using Ridgigullies and Connection Saddles.
Polypipe CGU also delivered a stormwater attenuation solution using over 800 metres of Ridgistorm-XL in diameters ranging from 750-1050mm, providing a system that would meet the demands of the site’s differing ground conditions. Each section of pipe was engineered to a specific length that met the exact requirements of the project. The final system allows for high volumes of water to be discharged into local watercourses.
In addition to the stormwater attenuation infrastructure, over 20 kilometres of Polypipe CGU’s cable protection product, Ridgiduct, was supplied to offer added protection to power lines, street lights and clean water systems.
Polypipe CGU’s approach meant that groundworkers facilitating the development at Watnall Road could efficiently connect the new build homes and commercial units to pre-installed networks.
“Polypipe CGU’s products have been used many times by Galliford Try as we have a really strong relationship,” Jamie Missenden, Project Manager at Galliford Try, said, “we made the decision to switch the specified system from traditional materials to a plastic-based solution and, at the Watnall Road site, the specified systems have been easy to install and the technical support from the Polypipe CGU team throughout has ensured a smooth process.”
