Bollin Park is a housing development in Wilmslow, Cheshire being developed by David Wilson Homes and Jones Homes that will include over 200 luxury homes. The development needed to address stormwater run-off from the site. The designers were able to attenuate all the necessary storage in over-sized pipes within the estate roads, eliminating the need for offline storage tanks and ensuring valuable land was not used for this purpose. The stormwater drainage system included 700m of 1200mm diameter AquaSpira Composite Steel Reinforced pipes that had several benefits over traditional concrete pipes including fewer deliveries to site and a 30% reduction in excavation due to the smaller diameter.

ollin Park is a housing
development in Wilmslow,
Cheshire, close to the town centre
and to open countryside. The site is being
jointly developed by David Wilson Homes
and Jones Homes and will eventually
accommodate over 200 luxury 4, 5 and 6
bedroom houses.
In common with all new housing
developments, the ever increasing
requirement to manage stormwater run-
off from the site needed to be addressed.
For this particular site, the designers were
able to attenuate all of the necessary
storage in over-sized pipes within the
estate roads, eliminating the need for
offline storage tanks, minimizing future
maintenance requirements, and perhaps
most importantly, ensuring that large
areas of valuable land did not need to be
set aside to accommodate large
underground storage tanks or ponds.
The stormwater drainage system
comprised 700m of 1200mm diameter
pipes, and due to the build plan, a
significant proportion of the pipes needed
to be installed within a very short period
of time. Having recently installed several
hundred metres of 900mm diameter
AquaSpira Composite Steel Reinforced
(CSR) pipes on a Taylor Wimpey homes
site in Preston, the civil engineering
contractor, Westbourne Civil Engineering,
had no hesitation in recommending the
use the AquaSpira pipes in place of
traditional concrete pipes.
Minimising disruption
One of the immediate benefits on site was
evident upon arrival of the first loads of
pipes. Each load contained 48m of
1200mm pipes, compared to just 15m per
load for concrete pipe, resulting in a
significant reduction in the total number of
deliveries to site from 47 down to just 15,
which in terms of minimizing disruption
was a significant benefit for all parties.
Once on site, the four packs of pipes
per load were safely offloaded in less
than 10 minutes with a fork attachment.
Pipes were then safely moved around site
in their packs, reducing the number of
movements by 80%.
Reduction in excavation
One of the main contributing factors to
the substantial reduction in programme
time was the 30% reduction in excavation
due to the much smaller outside diameter
of the pipes. The spigot & socket joints,
with integral seals and highly
recognizable bright red depth insertion
marker, enabled the pipes to be quickly
and accurately jointed, using the simple,
yet innovative Jointing Frame to safely
push the pipes home.
Whilst the operational, safety and
programme advantages the CSR pipes
are evident from sites such as this, the
opportunity for developers to achieve a
further, and potentially greater step-
change in programme and cost reduction
is achieved at the design stage.
Due to the reduced outside diameter of
CSR pipes, larger diameter pipes can be
designed and installed within a smaller
footprint. For example, a 1500mm diameter
CSR pipe can be installed within the same
footprint as a 1200mm diameter concrete
pipe, but the storage capacity increases
exponentially by over 56% from 1.13m3
to
1.77m3
. Larger pipes remain suitably light
and efficient to install, so what has been
‘impossible & impractical’ with concrete
pipe is now ‘possible & practical’ with CSR
pipe, providing an efficient method to
tackle stormwater storage.
