Geo²: Land Remediation Case Study
Facing a high profile project with zero room for delay, Geo² chose Meson to deliver a fast, reliable control solution that kept everything on schedule.
PART ONE
Deadlines are at risk
Geo², an environmental remediation company, secured a significant contract with a high profile client to provide a ground remediation solution for a major project.
Due to the tight project timeline, there was a significant risk to project milestones, financial commitment, and shipping deadlines, so it was important that teams involved could hit the ground running and establish a plan quickly.
To stay on track, Geo² needed an electrical partner and a solution that would align with their timeline and meet its growing requirements as this was a significant project to everyone involved. Confident in its ability to deliver on time, and keep the project moving forward, Geo² turned to Meson.
What Had Been Previously Installed
Meson’s first step was to conduct a design meeting with Geo²’s technical team to fully understand the project requirements. During this process, it became clear that the previous system had limitations, and the project presented a valuable opportunity to overcome to improve upon these in the new design.
The inherited system was based on outdated technology and originally designed for a small-scale, single purpose setup. It lacked the modularity, efficiency, and performance required for a project of this scale. Space constraints and legacy components meant that modification was limited, and the system had no provision for future expansion.

PART TWO
Fast and adaptable solutions
The solution that Meson designed was compact and efficient to maximise the space while ensuring high performance with a modular design that allows for easy expansion. This optimised design reduced the amount of cabling required, which cut down assembly time and potential quality issues.
To further reduce the risk of downtime, Meson used the highest quality, reliable components from Siemens with specialist automation software to design a suitable system.
The new control system featured remote monitoring and support to allow for real-time diagnostics and reduce the need for onsite visits while the software on the interface (HMI) flags key data for better oversite.
The remote monitoring software flags and real-time checks the efficiency of the system by tracking metrics such as valve positions, pressure levels, pump speeds, fault and alarm status as well as trend data analysis. By tracking these metrics, it allows the user to check for issues and ensure that the system is running efficiently and reduce the need to attend site as frequently.
The Clever Stuff
The system integrates several remediation processes into a single, coordinated control platform. This includes dual DPVE systems driven by high-vacuum liquid ring pumps for shallow soil treatment, pneumatic borehole pumps controlling groundwater within deeper bedrock, and a side-channel blower system managing vapour extraction from newly exposed pore spaces.
Our control solution was engineered to manage low-level VOC removal while maintaining stable, continuous operation across all treatment stages.
Resilience and uptime were central to the design. The control system manages duty/standby vacuum pump operation with automatic changeover to reduce the risk of downtime, alongside full system interlocking and fault handling. Remote monitoring functionality provides live performance data and automated alerts, allowing operators to respond quickly to any abnormal conditions.
To support long-term reliability, the controls also coordinate auxiliary plant including vapour cooling via a chiller and heat exchanger ahead of carbon treatment, a salt-free water descaling system to protect pumps, and chlorine dosing to mitigate biological fouling.
The result is a robust, remotely monitored remediation control system designed to operate safely, efficiently, and reliably in a demanding environmental application.

Meson go above and beyond
As well as providing a vastly improved system, the team travelled from Yorkshire to the EU to be on-site to assist with the commissioning of the system and, to make sure that the project rapidly progressed, the team worked 12-hour days.
The result of all this hard work was that the whole electrical process, manufacturing installation and commissioning were completed on time meaning that key deadlines were hit, and the project could continue unhindered.
