Drainage Design

The Flood and Water Management Act is putting into place Sustainable Drainage System (SuDS) Approval Bodies (SABs) to approve drainage proposals for new development. Our drainage consultants work with developers to make best use of your site and gain SAB approval. Our drainage services include:

  • conceptual drainage designs for master planning;
  • arrange permeability tests to assess the viability of infiltration techniques;
  • detailed SuDS design in accordance with the SuDS manual;
  • greenfield and pre/post-development runoff calculations to gain SUR 1 credits for the Code for Sustainable Homes or BREEAM assessment;
  • use of the latest industry standard drainage design software ensuring compliance with Sewers for Adoption;
  • obtaining consents and approvals from local authorities, water companies and the Environment Agency for the construction of outlet structures and discharge of foul and surface water; and
  • drainage problem investigations, solutions and expert witness services
