The Sustainable Drainage Systems (SuDS) Schedule 3 Post Implementation Review for the Welsh Government reviews the implementation of Schedule 3 of the Flood and Water Management Act 2010
Sustainable Drainage Systems are highly regarded as an effective mechanism for surface water management and risk-informed sustainable development. Sustainable drainage systems (SuDS) can be highly effective in managing urban water quantity and quality. In cities and towns, they are used to slow the flow of water, capture and store water, and depollute water by mimicking the way that nature manages water, to reduce the risk of flooding and pollution.
The report finds that all partners and stakeholders recognised the benefits and positive outcomes of Schedule 3 and that the issues in its implementation revolved solely around the delivery process and procedure. 17 common themes were identified and grouped into 4 categories:
- Governance and resource
- Consistency
- Technical requirements
- Affordability and enforcement
The report sets out long- and short-term recommendations, some of which include changes to legislation and standards, alongside supporting guidance and tools.
Whilst the report is focused only on implementation in Wales for the Welsh Government, the findings will be of interest to stakeholders in England where implementation is anticipated to begin in 2024. However, it is worth noting that there are fundamental differences in the legislative context and ‘ways of working’ between England and Wales and lessons learnt may not be directly transferable.
