Modular Drainage Systems.

Solving Surface and Sub-Surface
Water Challenges in Demanding
Infrastructure Environments

Independently tested and proven in real-world applications, our modular drainage systems offer a durable, longer-lasting alternative to traditional drainage methods, increasing drainage performance, enhancing asset resilience, reducing installation disruption and supporting sustainable infrastructure delivery.

About CWM.

Advanced Drainage System Engineering

Civil Water Management Ltd specialises in advanced drainage solutions and integrated approaches to surface and sub-surface water management.

Our Modular Drainage Systems (MDS) give recycled tyre rubber a valuable new purpose within durable, long-life drainage infrastructure.

As founders of Modular Drainage System Technology, CWM brings together almost three decades of technical advancement with independent testing, hydraulic modelling, controlled trials and live project deployments.

MDS is engineered and developed by CWM, with Rosehill Group as our manufacturing partner for specialist production and materials expertise.

Modular drainage Systems

Integrated Drainage System Engineering.

Modular Drainage Systems provide integrated, high-performance drainage solutions for demanding infrastructure applications, including constrained, shallow-depth and retrofit environments, with deployment across the UK and internationally within highways, active travel, rail, civil engineering and major infrastructure projects.

Through award-winning drainage innovation focused on integrated design, high performance, long-term resilience, robust materials, reduced maintenance and greener construction methods, we unlock the approval and implementation of a holistic approach to water management.

Crucially, MDS overcomes the limitations of conventional drainage methods by significantly improving the immediacy of how water is taken in and conveyed, while reducing excavation, material use, installation impact and future intervention.

CWM deliver trusted solutions for planners, architects, drainage designers, contractors, civil engineers, environmental specialists, transport organisations, government and local authorities.

Our work has received industry recognition across transport and civil engineering, with grants and awards recognising supplier excellence, technology, sustainability and decarbonisation from the Department for Transport, Connected Places Catapult, Rail Business Awards, the Permanent Way Institution and RailTech Europe.
