Ecologia to Conquer Contamination with Rockwell Automation

Ecologia, a UK-based environmental contractor, faced a geographically complex remediation challenge at a large petrochemical facility in Italy. Volatile hydrocarbon contamination in shallow soils and groundwater required a multi-phase extraction system to operate continuously for approximately three years. The conventional approach would have required one or two full-time engineers stationed on-site for the entire project duration — a costly, carbon-intensive arrangement that also limited Ecologia's ability to scale its services internationally. With operations spanning UK headquarters and a remote Italian site, the lack of remote monitoring capability made timely decision-making and predictive maintenance effectively impossible without costly site visits.

Ecologia deployed three identical, self-contained treatment units — housed in 20-foot shipping containers — each equipped with an ATEX-rated HMI running Rockwell Automation FactoryTalk View SE, Allen-Bradley CompactLogix programmable automation controllers (PACs), and 3G/GPRS modems paired with WIN-911 SMS software for remote alarm annunciation. The CompactLogix PACs monitor over 40 parameters per unit — including flow rate, groundwater levels, pipe pressure, temperature, and contaminant gas concentration — and can trigger emergency shutdowns autonomously. Cougar Automation, acting as system integrator, designed the control architecture and trained Ecologia's engineers on Logix5000 development software, FactoryTalk View HMI configuration, WIN-911 alarm management, and VPN/3G remote access setup. WIN-911's intelligent escalation logic ensures that unacknowledged alerts are automatically routed to the appropriate personnel.

Remote automation eliminated the need for permanent on-site staffing across a three-year project, delivering measurable reductions in travel, subsistence, and carbon emissions. Key outcomes include:

• Site visit time reduced from ~3 days to under 1 hour for monitoring and parameter adjustments, conducted remotely from Ecologia's Kent headquarters
• Reduced operational costs by eliminating the need for resident engineers in Italy
• Lower carbon footprint through near-elimination of international travel for routine maintenance
• Faster decision-making: real-time data access allows process adjustments within minutes of an alert
• The solution also enabled Ecologia to position remote automation as a repeatable capability for future international contracts with multinational clients.

• Remote telemetry and ATEX-rated automation can make long-duration environmental remediation projects economically viable without permanent on-site staffing.
• Intelligent alarm escalation (via tools like WIN-911) is critical when operating hazardous systems across time zones — human acknowledgment must be enforced, not assumed.
• Partnering with a specialist system integrator (Cougar Automation) for both architecture design and staff training accelerated deployment and reduced knowledge gaps.
• Standardising on modular, identical control units across multiple site locations simplifies remote monitoring and reduces maintenance complexity.
• Reducing site visits is not just a cost saving — for international contracts, it is often the deciding factor in project feasibility.
