Schedule 3 - New SuDs Legislation

Reduce surface water flood risk, pollution and alleviate the pressure on traditional systems

Understand the impact of new Sustainable Drainage System legislation on your planning
Application

New government legislation that will affect planning applications is expected to be implemented in 2024. The legislation relates to Sustainable Drainage Systems (SuDS) and will, according to the government, “reduce the risk of surface water flooding, pollution and help alleviate the pressures on our traditional drainage and sewerage systems”.

Sustainable Drainage Systems (SuDS) have long been recognised by civil engineers as an important way to manage surface water, manage flood risk, improve water quality, improve biodiversity and provide amenity benefits (the four pillars of SuDS).

Schedule 3 of the Flood and Water Management Act (2010) provides a framework for the approval and adoption of drainage systems, a sustainable drainage system approving body within unitary and county councils, and national standards on the design, construction, operation, and maintenance of sustainable drainage systems for the lifetime of the development.

Following the publication of the review, regulations and processes for the creation of sustainable drainage systems at new developments will now be devised. Implementation of the new approach is expected during 2024.

HOW WE CAN HELP

Support, Advice and SuDS Design

Our experienced team of engineers are increasingly being commissioned by local authorities to provide flood risk expertise for planning applications. This includes the technical review of the drainage and flood risk aspect of planning applications including the discharge of relevant conditions.

RAB also provide an expert technical resource to support the Lead Local Flood Authority Statutory Consultee role for both major planning applications and minor applications, including pre-application discussions, outline and full applications, reserved matters, and discharge of conditions. We can also attend online meetings with applicants when required.

RAB have a team of experienced engineers who are able to develop a SuDS network (from the master planning stage all the way through to detailed design), which meets the four pillars of SuDS and the ever more stringent targets of local authorities, following the upcoming enactment of Schedule 3.

Sustainable Drainage FAQs

As areas become increasingly developed and urbanised, the natural runoff of surface water is

restricted. Sustainable drainage systems, also known as ‘SuDS’ are the best and most

environmentally friendly way to manage surface water.

SuDS are now considered an integral part of the planning application process. This affects all

developments ranging from large commercial developments down to small residential projects. RAB have experience and expertise to help with all aspects of SuDS including:

  • Outline Drainage Strategy and Design
  • Discharge Consents and Adoption Agreements
  • Foul Sewerage Design and Foul Sewerage Adoption

Schedule 3 of the Flood and Water Management Act (2010) provides a framework for the approval
and adoption of drainage systems, a sustainable drainage system approving body within unitary and county councils, and national standards on the design, construction, operation, and maintenance of sustainable drainage systems for the lifetime of the development.

Schedule 3 of the Flood and Water Management Act 2010 was enacted in Wales 1 May 2018.
A new approach to sustainable drainage was announced by the UK government in January 2023,
following pressure from industry to act now.

The legislation relating to sustainable drainage systems (SuDS) will, according to the government,
“reduce the risk of surface water flooding, and pollution and help alleviate the pressures on our
traditional drainage and sewerage systems”.

The move follows an open letter, sent to Prime Minister Rishi Sunak in December, where industry
experts “strongly urged” him to implement Schedule 3 of the Flood and Water Management Act
2010. According to the letter to the prime minister, the SuDS part of the act was “relaxed” in 2014
and high-quality SuDS have not been made mandatory so far due to “misconceptions on cost and applicability”.
“The [SuDS] approach could have been normalised as a standard good practice many years ago.
“Please do not waste any more time; implement Schedule 3 of the Flood and Water Management
Act 2010 further to the current government review,” the letter ends.

As well as Balmforth, the letter has been signed by a large cohort of experts including Terry Fuller,
chief executive of the Chartered Institution of Water and Environmental Management, Christine
McGourty, CEO of Water UK, and Professor Jim Hall, professor of climate and environmental risks at Oxford University.

Following the publication of the review, regulations and processes for the creation of sustainable
drainage systems at new developments will now be devised. Implementation of the new approach is expected during 2024.

The Government will now give consideration to how Schedule 3 will be implemented, subject to final decisions on scope, threshold and process, while also being mindful of the cumulative impact of new regulatory burdens on the development sector. This will include a public consultation later this year, which will collect views on the impact assessment, national standards and statutory instruments.
