Drainage
& SuDS
Below-ground drainage and sustainable drainage systems designed to manage surface water responsibly, from attenuation tanks to soakaways and permeable surfacing.
Drainage and SuDS contractor managing surface water responsibly
Modern planning conditions increasingly require sustainable drainage systems (SuDS) that manage surface water at source rather than simply piping it away. Lawday installs foul and surface water drainage, attenuation tanks, soakaways and permeable surfacing, working alongside consulting engineers to coordinate SuDS design with the wider site strategy.
Every installation is backed by CCTV survey and connection testing, giving clients confidence that below-ground drainage will perform for the life of the asset – from retail and education sites through to heritage-sensitive locations where surface water has to be managed without disturbing the setting.
What’s included
Foul & surface water drainage installation
Below-ground pipework, manholes and connections installed to adoptable and Building Regulations standards.
Attenuation tanks & soakaway systems
Attenuation and soakaway systems sized and installed to agreed drainage strategies, reducing discharge to greenfield rates.
SuDS design coordination
Close coordination with the project’s drainage engineer to keep SuDS features buildable and on programme.
CCTV survey & drainage connections
Pre- and post-installation CCTV survey, with connections tested and recorded for handover.
