SAB Drainage Design and Application Service for Developers

SAB Drainage Deisgn and approvals have been a statutory requirement in Wales since 2019. This means that all development, with an area greater than 100m2, will require a SAB Approval. Compliance with the full range of published standards are mandatory, regardless of any planning approvals or conditions set by the LPA.

CES Consulting can support you, through the SAB application process from strategy, design through to application and approval. We have been helping Developers, Architects and Planning Consultants gain SAB approvals since 2019 and have a 100% sucess rate.

All Surface Water Drainage for applicable development must be designed and built in accordance with Statutory SuDS Standards published by Welsh Ministers. SAB/SuDS schemes must be approved by the SuDS Approving Body (SAB), before construction work begins.

The application process can often take more than seven weeks and early engagement is highly recommended.

Drainage Design Approach

Core principles under the new arrangements as contained within the amended Flood and Water Management Act 2010 are:

Surface Water is to be managed on or as close to the surface and source of the runoff as possible.
Ensure pollution is prevented at source, not to rely on the drainage system to treat it.
Protect people from increased flood risk, and the environment from ecological changes in flow rates, patterns and sediment movement caused by the development.
Use a Management Train in series across a site rather than a single “end of pipe” feature, such as a pond, to serve the whole development.
The Sustainable Drainage Systems should perform safely, reliably and effectively over the design life of the development. They must consider the need for reasonable levels of maintenance.
Avoid the need for pumping where possible.
The drainage system should be affordable, considering both construction and long-term maintenance costs and the additional environmental and social benefits afforded by the system.

CES can advise on the best form of SuDS/SAB strategy on a development by development basis.
