For small low risk developments the information identified will be sufficient for the Drainage Assessment. Once you have all the required information this can be uploaded to the tool. On completion, a full drainage assessment will be emailed to you and will be suitable for submission with your application.
If your site doesn't meet the requirements for this web form to generate a SWDA then the validation checklist can be sent to your drainage professional to design a suitable surface water drainage solution.
Please note that the SWDA must include all the required testing, calculations and plans in a single PDF document.
