About drainage strategy (suds)
A drainage strategy sets out how rainwater and foul water from a new development will be dealt with, usually favouring sustainable drainage systems (SuDS) that slow water down and let it soak away rather than sending it straight to a sewer. Councils often ask for one with applications for new homes, and it can also come up as a planning condition.
Getting signed off in England
In England, your council’s building control team or a registered building control approver checks the work. They issue a completion or final certificate once they have the reports they need, such as the as-built SAP, EPC, air test and any sound or ventilation test results.
