Stormwater Management

What is stormwater management?

Stormwater drainage is the process of managing, controlling, and treating standing water to reduce the risk of flooding, erosion, and water pollution. 

In urban areas, where development disrupts natural drainage patterns, stormwater drainage systems are crucial for mitigating the environmental impact of excess runoff.

By slowing down, storing, or redirecting stormwater, these systems help prevent overloading sewers and waterways while improving the long-term sustainability of urban infrastructure.

When you’re planning a new development, whether it’s residential, commercial or a large infrastructure project, it’s vital that water management provisions can meet demand.

Stormwater control

Marshalls offers a wide range of stormwater control products designed to manage flow rates and volumes across various drainage schemes. From attenuation tanks to flow regulation systems, our stormwater systems are built to perform reliably, even in challenging conditions.

Each system is designed to optimise site drainage by slowing down stormwater discharge into sewers or natural watercourses, helping to manage peak flows during and after heavy rainfall.

Stormwater treatment

Treating stormwater before it enters the environment is key to reducing pollutants like oil, silt, and debris. Marshalls’ stormwater treatment systems can be integrated with filtration and separation technology to capture contaminants at the source.

Our treatment solutions play a crucial role in protecting natural watercourses and maintaining water quality in both rural and urban areas.

Why is stormwater management important?

Effective stormwater drainage systems are vital in protecting communities and critical infrastructure from the growing risk of flooding and water pollution. 

As more homes and commercial developments are built on floodplains and other high-risk areas, the land's natural ability to absorb rainwater is significantly reduced.

This increases the volume and speed of surface water runoff, placing extra pressure on drainage systems and heightening the risk of localised flooding. 

Without proper stormwater drainage solutions, roads, homes, and public spaces can quickly flood during heavy rain or when snow melts.

To address this, Marshalls offers a wide range of stormwater drainage and management systems that include attenuation and control products and solutions that support wider flood resilience strategies. These include:

• Sustainable Drainage Systems (SuDS) for stormwater control that mimic natural water processes to slow and store runoff close to where it falls.

• Rainwater management systems that collect and repurpose water for non-potable use, helping reduce demand on mains water supplies.

Together, these systems help prevent floods, improve water quality, and support developers in meeting environmental and planning targets. Investing in quality stormwater drainage is crucial for both urban and rural developments to create safer, more resilient communities.
