Stanton Bonna Manhole System supports Marks & Spencer carbon neutral plan

Marks & Spencer’s ‘Plan A’ target is to be ‘the most sustainable major retailer by 2015’. The construction of the 900,000sq ft site of their new Castle Donington Distribution Centre was no exception with processes and products fitting this ethos.

"...just what we needed to meet the developers requirements”

Stanton Bonna’s watertight manhole system fits the criteria perfectly, thanks to its significantly lower footprint when compared to traditional manholes.

Winvic Construction, who were awarded the tender, originally looked at standard manholes from two other companies but selected Stanton Bonna’s Perfect Manhole Systems due to quick, easy installation and lower carbon footprint.

Stanton Bonna supplied 18 x DN1200 and 5 x DN1500 Perfect Manhole Systems including base units, rings, watertight gaskets and slabs. In addition to this we also supplied over 70m of circular pipes, rocker pipes, spigots, sockets and bends.

Dan Barker, Senior Engineer for Winvic Construction said “The convenience of using a pre-benched system saved us significant time during installation plus the low carbon footprint of this easy, safe, quick manhole meant it was just what we needed to meet the developers requirements”.

The Perfect Manhole System can be installed in a day ensuring safety, as no working for long periods in confined spaces. It is quicker to install than traditional systems as no waiting for benching to dry and easier to fit together with the watertight gaskets.

In a study audited by independent consultants Carbon Clear, The Perfect Manhole System was found to have a 30-43% lower carbon footprint than traditional, boxed based and plastic manholes.

In the same study, concrete pipes were found to have a 35% lower carbon footprint than that of plastic pipes.
