Drainage Design

Sustainable Drainage Systems (SuDS) are widely recognised as the way forward to tackle water quantity and quality within the built environment. Delivery of SuDS has become entrenched within the planning system, and should be a primary consideration for all developments. 


Our drainage services include:

  • conceptual drainage designs for master planning;
  • managing 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
