Original product specification
Originally, a 314m³ attenuation crate system had been specified.
Our solution
In order to meet the requirements of the build, we installed a single run of
1400mm diameter pipe around the building which acted as a carrier pipe, we then combined this with an
attenuation tank to collect the roof and surface water drainage.
The benefits
of our solution
- We eliminated the need for 11 manholes which were in the original specification
- We reduced the excavation by 780mm across the site
- We considerably reduced the amount of underground pipe work required
- We installed a full retention separator downstream of the attenuation tank which provided further cost savings
