Approval standards
National Statutory Standards for Sustainable Drainage Systems
A drainage system must meet certain standards for the SAB to approve and adopt it.
If the standards aren't met, the application will be refused. So, it's a good idea to talk to the SAB early and get pre-application advice.
Read the full standards document on the Welsh Government website.
