SuDS in Sutton’s Schools

A council-led programme bringing sustainable drainage and nature-based features onto Sutton’s school grounds, to reduce surface-water flooding and support outdoor climate learning. My part was the Environment Agency’s partnership role: fortnightly progress meetings and checks with the council.

ContextWhy it mattered

Surface water is England’s most widespread flood risk: about 4.6 million properties are exposed, 43% more than the previous assessment found. London has around 3,500 schools. In July 2021 storms flooded more than 550 homes and businesses in Westminster alone. Sustainable drainage systems (SuDS) on school roofs, playgrounds and green space slow and store rain where it falls. London programmes have targeted the schools in the highest surface-water risk bands, and the Department for Education now pays up to half the cost of school SuDS.

Partners: London Borough of Sutton (lead local flood authority; programme lead); Schools in Sutton

My roleWhat I did

Flood Risk Advisor, Partnerships & Strategic Overview (PSO): fortnightly progress meetings and checks with the council

  • Held fortnightly progress meetings with the council, the programme lead.

PeopleWho it affects, and how results were shared

Who it affects

  • Pupils, staff and families at schools in surface-water risk areas
  • Neighbouring homes that share the local drainage network

How people were involved

  • Fortnightly progress meetings and checks with the council. my record
  • The council’s programme aimed to raise children’s awareness of flood risk through green education. council

What changes for them

  • School SuDS slow and store rain on site, so less water reaches the drains during storms. programme aim
  • Sendai target (d) counts disruption of basic services, including education. School grounds that flood less mean less disruption.

Public evidenceLondon has around 3,500 schools. The GLA’s Climate Resilient Schools programme prioritised 100 schools in the top 10% for surface-water flood risk.

MethodsMethods and tools

  • Sustainable drainage systems (SuDS) and nature-based solutions
  • FCERM grant-in-aid and partnership funding (2020 rules)
  • Fortnightly progress meetings and checks

OutcomeWhat happened

A council-led programme of est. >US$2m that I supported through 2023–25. The council led delivery on school sites.

TransferHow this applies internationally

ADB RRBI. Experience of a borough programme of small green–grey measures spread across many sites. RRBI promotes “green–gray flood management that combines nature-based solutions (floodplains, wetlands, sponge cities)”. Having followed such a programme, I can judge how far basin plans and tools account for these measures.

UNDRR (capacity strengthening; Sendai target (d)). Risk reduction in education facilities, paired with risk awareness for children. Sendai target (d) and para 30(c) single out schools as critical facilities. The programme combined physical risk reduction with learning.

World Bank (implementation support). Progress monitoring of a council-led, co-financed drainage programme. Regular progress meetings and checks with an implementing partner are the core of support to a project implementation unit (PIU). They feed disbursement forecasts and the Implementation Status and Results Report.

ADB project administration. Co-financing several partners in one programme. This mirrors how ADB tracks cofinancing and counterpart funds in a project administration manual.
