	On January 10 2023, DEFRA published "[https://www.gov.uk/government/publications/sustainable-drainage-systems-review The review for implementation of Schedule 3 to The Flood and Water Management Act 2010]". This report sets out the findings of a review which recommends implementation subject to final decisions on scope, threshold and process once a full regulatory impact assessment has been completed. The assessment will look at different options and the expected costs and benefits. The government has accepted this recommendation. Defra will carry out a consultation in order to collect views on the impact assessment, national standards and statutory instruments in 2023.

		+	The [https://www.gov.uk/government/publications/national-planning-policy-framework--2 National Planning Policy Framework] (NPPF), published by the Ministry of Housing, Communities and Local Government in December 2024, states: ‘A sustainable drainage system controls surface water run off close to where it falls, combining a mixture of built and nature-based techniques to mimic natural drainage as closely as possible, and accounting for the predicted impacts of climate change. The type of system that would be appropriate will vary from small scale interventions such as permeable paving and soakaways that can be used in very small developments to larger integrated schemes in major developments.’

Sustainable urban drainage systems can provide an alternative to, or addition to, traditional drainage systems where surface water is drained directly and quickly into underground, piped drainage.

−	~~Sustainable urban drainage systems can provide an alternative to, or addition to, traditional drainage systems where surface water is drained directly and quickly into underground, piped drainage.~~	+	= Why are SUDS necessary? =

−	As population has increased, particularly in urban areas, and ‘soft’, permeable landscape has been replaced with hard surfaces, surface water runoff has reached traditional piped drainage faster and in larger quantities. This has been exacerbated by the loss of rural features that might once have slowed the passage of surface water, being replaced with large, intensively farmed fields that rapidly discharge surface water into piped drainage or waterways that make their way into urban areas.	+	As population has increased, particularly in urban areas, and ‘soft’, permeable landscape has been replaced with hard surfaces, surface water runoff has reached traditional piped drainage faster and in larger quantities. This has been exacerbated by the loss of rural features that might once have slowed the passage of surface water, being replaced with large, intensively farmed fields that rapidly discharge surface water into piped drainage or waterways that make their way into urban areas. The result has been higher peak flows and serious flooding of urban areas, pollution, damage to habitat and contamination of groundwater sources.

	Sustainable urban drainage systems aim to mimic 'natural' drainage by adopting techniques to deal with surface water runoff locally, through collection, storage, and cleaning before allowing it to be released slowly back into the environment.

	According to CIRIA, ‘SUDS techniques seek to capture, use, delay or absorb rainwater, rather than reject it as a nuisance or problem. Sustainable drainage delivers multiple benefits. As well as delivering high quality drainage whilst supporting areas to cope better with severe rainfall, SuDS can also improve the quality of life in developments and urban spaces by making them more vibrant, visually attractive, sustainable and resilient to change by improving urban air quality, regulating building temperatures, reducing noise and delivering recreation and education opportunities.’		According to CIRIA, ‘SUDS techniques seek to capture, use, delay or absorb rainwater, rather than reject it as a nuisance or problem.

	In October 2012, Schedule 3 of the Flood and Water Management Act 2010 came into force. This created the power to require the inclusion of sustainable drainage of surface water in developments that need planning approval or have drainage implications. It removed the automatic right, established by the Water Industry Act, to connect to public sewers and instead gave powers to local authorities as SUDS Approving Bodies (SABs) to approve new drainage systems and their connection to public sewers.

In addition it was announced that a threshold of 10 dwellings or more, or equivalent non-residential or mixed development will apply. See SuDS consultation for more information.
