In order to eliminate the need to use valuable land to accommodate the stormwater attenuation for the site, the drainage designers incorporated all of the storage requirements into large diameter, combined carrier and storage pipes beneath the road layout. In total, 179m of 1200mmØ, 21m of 1050mmØ, 353m of 900mmØ and 259m of 600mmØ have been installed.
Whilst AquaSpira pipes proved to be highly cost effective, there were additional key benefits for Taylor Wimpey.
- Programme Improvements - derived from the ease and speed of installing light weight, yet robust spigot & socket pipes. Installation speed was also accelerated due to the massive 25-30% reduction in excavation compared to that required for concrete pipes.
- Health & Safety – weighing in at just 5% of the weight of concrete pipes, handling and installing AquaSpira pipes was a much safer operation.
- Design Optimization – The minimal outside diameter of the pipe and slimline joints minimized the space required to accommodate the pipes in the road.
- Environmental – the unique, composite structure of AquaSpira pipes utilizes less raw material than any other pipe technology. Pipes also contain a proportion of recycled steel, resulting in an average 25-30% total recycled content.
- Reduced Site Deliveries and Safer & Quicker Offloading – due to an average 60% greater load utilization than for concrete pipes.
Ian Smith, Managing Director of Taylor Wimpey North West commented “To keep one step ahead of our competitors we have a keen interest in utilizing innovative products which deliver genuine efficiency and environmental improvements. We also have a responsibility to ensure and enhance Health & Safety on site. AquaSpira’s pipe system has delivered tangible benefits and we will now actively consider the use of the product when planning future developments”.
