Highway Drainage for New Developments in Crawley
2 min readCrawleyBy AA Drainage
New estate roads need drainage built to a standard the highway authority will adopt. Getting it right avoids costly remedial work at handover.
What's involved
Highway drainage on new developments usually includes:
- Road gullies and connections
- Carrier drains and manholes
- Attenuation storage to control flow
- Outfalls with flow controls
Working to adoption standards
Roads intended for adoption must be built to the highway authority's specifications, with inspections during construction. We work closely with engineers and inspectors throughout.
Sustainable drainage
Many schemes now include sustainable drainage features to slow water down and reduce flood risk. We install the below-ground elements alongside the road build.
