Wastewater Management Systems

Marshalls’ wastewater management systems are made from reliable, precast concrete and are suitable for modern infrastructure and drainage challenges.

Engineered to ensure performance and speed our products help manage wastewater efficiently across domestic, commercial, and industrial developments.

Whether you're facing sewer overflow issues, managing combined drainage, or require specialised sumps and chambers, our offsite-manufactured systems are designed to save time, minimise disruption, and ensure long-term reliability. Additionally, we can support your upcoming AMP8 (Asset Management Period 8) projects.

What are wastewater management systems?

Wastewater management involves collecting, treating, and safely disposing of wastewater from homes, businesses, and industrial sites. Effective systems are crucial for maintaining hygiene, preventing environmental contamination, and supporting modern infrastructure.

Marshalls’ wastewater range includes precast concrete modular tanks, wall panels, circular chamber systems, valve chambers, wet well chambers, and combined sewer overflow units. 

These systems are specifically designed to streamline installation and reduce on-site labour, minimising downtime while maintaining performance and compliance.

By using precast concrete components, you benefit from reduced land use, shorter construction times, and increased control over build quality.

What are the different types of wastewater management products?

Our range of wastewater management products includes a full range of offsite wastewater solutions, including:

Combined pump and valve chambers

These utilise our caisson shaft system and are available in 3000mm, 3660mm, and 4000mm diameters, depending on the valve and pipework requirements.
