What it is
A SuDS scheme and drainage strategy manage surface water runoff sustainably, controlling discharge rates and volumes to protect people, property and watercourses.
When you need it
Required to discharge drainage conditions on most new developments, and to support planning wherever surface water is a consideration.
What you get
What's included
Greenfield/brownfield runoff rate calculations
SuDS management train design (permeable paving, attenuation, infiltration)
Discharge hierarchy assessment and outfall strategy
Drainage strategy report for LLFA/council sign-off
Infiltration testing and right-sized attenuation often remove the need for the oversized storage a default design assumes — real savings on concrete, land-take and maintenance.

FAQs
Frequently asked
What is a drainage strategy?
A document showing how surface water will be managed on your site — how much runs off, where it goes, and how it's controlled — to satisfy the Lead Local Flood Authority.
How can SuDS save money?
By using infiltration testing and right-sized attenuation we often reduce the storage volume and land-take a template design would assume, cutting concrete and groundworks.
