The National Drainage Show returns to ExCeL London on 25–26 November 2026, bringing together professionals from across the drainage, water management, utilities, civil engineering and infrastructure sectors for two days of innovation, networking, knowledge sharing and industry debate.
The event provides a dedicated meeting place for the organisations responsible for designing, installing, maintaining and managing the drainage infrastructure that supports communities, businesses and development across the UK.
With increasing pressure on drainage networks from population growth, urban development, extreme rainfall, ageing infrastructure and the need for more sustainable water management, the National Drainage Show will showcase the latest products, technologies and services helping the industry meet these challenges.
Connecting the drainage community
The National Drainage Show brings together drainage contractors, civil engineers, consultants, local authorities, water companies, utilities, developers, infrastructure owners, manufacturers and specialist suppliers under one roof.
Visitors will have the opportunity to meet leading suppliers, discover new products and technologies, compare solutions and discuss the practical challenges facing drainage and water management projects.
The exhibition will cover a wide range of applications, including drainage systems, sewer networks, surface water management, pumping, inspection and maintenance, pipe rehabilitation, sustainable drainage systems, water management, surveying, monitoring and asset management.
By bringing together different parts of the drainage supply chain, the event provides an opportunity for professionals to develop new relationships and share experience across the industry.
Innovation and sustainable drainage
The need for resilient and sustainable drainage infrastructure has never been greater. Increasing instances of extreme rainfall and urban development are placing additional pressure on existing networks, while new approaches to water management are creating opportunities to improve resilience and reduce environmental impact.
The National Drainage Show will provide a platform for companies to demonstrate solutions designed to improve the performance, efficiency and sustainability of drainage infrastructure.
CPD-accredited seminars, including a 2-day SuDS Theatre
Visitors will be able to explore developments in areas including SuDS, smart drainage, monitoring and telemetry, sewer inspection, trenchless technology, pumping, flood mitigation, water reuse and asset management. The event includes a dedicated 2-day SuDS Theatre, populated by experts offering invaluable advice and solutions.
The show will also highlight technologies that can help infrastructure owners and operators improve maintenance, identify problems earlier and extend the working life of existing assets.
Knowledge and industry debate
Alongside the exhibition, the National Drainage Show will feature a programme of seminars, presentations and expert discussions, addressing key issues affecting the drainage and water management sectors.
Topics will include sustainable drainage, climate resilience, surface water management, sewer infrastructure, asset maintenance, construction, regulatory developments, infrastructure investment and emerging technologies.
The programme will provide visitors with an opportunity to hear from industry experts, gain practical insight and keep up to date with developments that could influence future projects and working practices.
A meeting place for decision-makers
The National Drainage Show is designed to connect suppliers with the professionals responsible for specifying, purchasing, installing and managing drainage and water management solutions.
Visitors will include decision-makers and technical professionals from local authorities, water companies, utilities, civil engineering contractors, developers, consultants, construction companies and infrastructure organisations.
