Civil Engineering – Drainage

Lyons O’Neill are a team of professionals with the necessary skills and experience to champion the use of SuDS within the overall design of the development from an early stage. The civil engineering team are capable of understanding the site’s particular surface water management needs and opportunities. We have the knowledge and experience in using SuDS-based solutions to influence the holistic design of a development’s drainage system.
