Bristol Airport

South West's largest airport prepares foundations for expansion


Bristol International Airport has embarked on a redevelopment and expansion programme which will see it double the floor space of the existing terminal building, build two new multi-storey car parks for 3,850 cars and a 4800m2 administration building, and create an underground fuel storage depot. As a result of the expansion it is estimated that, by 2019, overseas tourism to the South West will inject an additional £94 million into the region’s economy.


The main purpose of the project is to achieve status as the South West’s major airport through an increase in the number of passengers using the airport from 6 to 9 million by 2015, and to 12.5 million by 2030, by attracting more airlines and providing new routes and direct destinations.


The £7 million scheme to construct the extended western parking apron for aircraft, from 18 to 33 stands, commenced in 2012.


Commissioned by Volker Fitzpatrick, the main contractor, on behalf of the Airport, our brief was to supply and install surface water management and sustainable drainage systems.

How it works

New sustainable drainage systems comprising a large soakaway with a capacity of 1,665m3 have been installed in order to manage water runoff away from aircraft standing areas quickly and efficiently.


The drainage scheme has minimised the potential for groundwater pollution by surface water contaminated by aircraft fuel and de-icing chemicals.


This installation has also provided the foundation for further expansion anticipated to take place in 2016; the modular format and flexible construction of SDS GEOlight® will allow 450m3 of additional volume to be installed as the future growth of the Airport demands.

Bristol Airport was first officially opened on 31 May 1930 by HRH Prince George, becoming only the third civil airport in the country. In 1957 it was relocated to its present site since when passenger numbers have grown from 33,000 pa to over 6 million 50 years later.

What our other Customers say

SDS was instrumental in securing planning approval by designing a bespoke SuDS solution that was able to meet stringent discharge rates; through the prevention of flooding, by using source control techniques to manage the run-off from the site, any impact on the receiving watercourses is kept to an absolute minimum.
