Drainage Schemes

We provide drainage design services for residential projects tailored to each stage of your project —whether you’re preparing a planning application, working through technical design, or seeking validation from the Local Planning Authority (LPA).

We focus on supporting clients to achieve planning success at the same time as designing in the best measures we can for sustainability and climate change resilience.
Our designs are grounded in SuDS principles, helping reduce flood risk, protect water quality, and improve the environmental value of each site by managing surface and foul water effectively, sustainably, and in full compliance with national and local requirements.
We regularly work with: architects, planning consultant, builders, contractors and property developers.

Drainage schemes may include:

  • Drainage strategies for early-stage feasibility and outline planning applications
  • Detailed drainage designs for full planning or reserved matters and discharge of planning conditions
  • Drainage assessments, plans or statements for validation
  • Detailed drainage layout drawings for construction and building control
  • Design of foul and surface water systems – both private and adoptable drainage
  • Full hydraulic simulation and calculations
  • Manhole Schedules
  • SuDS maintenance Plans
  • CDM Designer’s Risk Assessments
  • Liaison with water companies for connection and diversion applications

Why SuDS Matter

Sustainable Drainage Systems (SuDS) help manage water in a way that mimics natural processes. Where feasible, we prioritise infiltration techniques and include features like attenuation tanks, swales, and permeable paving to:

  • improve water quality
  • reduce runoff and peak flows
  • support biodiversity and amenity
  • comply with the SuDS policies and planning expectations

All our designs are tailored to the specific characteristics of your site and based on current planning policy, Environment Agency, DEFRA, and Lead Local Flood Authorities guidance.

Our goal is to help you achieve compliance without compromising on quality or creativity.
