Nitrate Neutrality Solutions
Our cyclic activated sludge technology removes nitrates from wastewater, enabling housing developments to meet regulatory requirements. The compact, odourless systems operate with total nitrate values below 10mg/l, offering above/below ground installation options. With 400+ global installations since the 1960s, this proven solution provides cost-effective, low-maintenance treatment for developments of 100+ units while ensuring compliance with UK watercourse discharge regulations.
EPC Projects
We deliver full lifecycle EPC projects across energy, water, and nuclear sectors. Our in-house capabilities cover design, manufacturing, commissioning, and project management. By integrating process, mechanical, electrical, and automation engineering with early client engagement, we optimise whole-life solutions. Our 65-year track record includes major capital projects completed on time and budget, supported by multidisciplinary teams ensuring constructability and operational efficiency.
Offsite Manufacture
Our offsite manufacturing facilities produce precision-engineered modules for rapid deployment. This approach reduces on-site construction time by up to 40% while maintaining quality control. We specialise in prefabricated systems for water treatment plants, mechanical packages, and control systems. The method enhances safety through reduced site personnel and improves project predictability through factory-controlled production environments.
Automation Systems
We design and implement custom automation solutions for process optimisation. Our MEICA expertise covers instrumentation, control panels, and SCADA systems integration. The solutions enhance operational efficiency through real-time monitoring and data analytics. We provide turnkey automation packages from concept design to commissioning, ensuring compliance with industry standards and seamless integration with existing infrastructure.
Nuclear Engineering
We deliver nuclear sector projects with specialist expertise in safety-critical systems and regulatory compliance. Our services include reactor support systems, waste management solutions, and facility upgrades. We maintain rigorous quality assurance protocols and collaborate with strategic partners to provide innovative engineering for new build and decommissioning projects across the nuclear lifecycle.
