Legionella, water quality and performance monitoring for cooling towers, protecting public health, system efficiency and regulatory compliance.
Cooling towers are a well-documented source of Legionella bacteria and scale-forming deposits when water treatment and monitoring are not properly managed. Green Vertex delivers a complete cooling tower monitoring program — combining water quality testing, Legionella culture and PCR analysis, and system performance checks — to protect building occupants, maintain equipment efficiency and satisfy regulatory and insurance requirements across Saudi Arabia and the GCC.
Poorly maintained cooling towers create ideal conditions for bacterial growth and scale build-up, both of which carry real health and operational cost. Our technicians combine routine water sampling with performance checks on drift eliminators, biocide dosing and heat exchange efficiency, giving facility managers a single program that covers both public health compliance and mechanical reliability.

Routine and event-based Legionella pneumophila testing using culture and PCR methods. Results are benchmarked against recognized action levels to trigger timely remedial response.
Testing of pH, conductivity, biocide residual, total dissolved solids and other key water chemistry parameters. Keeps treatment dosing within the optimal operating range.
Site risk assessments identifying conditions that favor Legionella growth and scale formation. Findings feed directly into your water safety plan and control scheme.
Independent verification that biocide dosing and scale/corrosion inhibitor programs are performing as designed. Confirms chemical treatment is actually controlling risk, not just being applied.
Assessment of cooling tower thermal performance, drift loss and water consumption. Identifies opportunities to improve efficiency and reduce water use.
Development of site-specific water safety plans and control schemes for cooling water systems. Provides a documented, auditable framework for ongoing management.
Review the site, facility or project and confirm objectives and applicable regulatory requirements.
Develop a project-specific methodology, schedule and quality assurance plan.
Mobilize qualified specialists and calibrated equipment to site or to the desk-based study.
Carry out field work, testing, sampling or engineering review in line with the agreed plan.
Validate raw data and results through structured QA/QC checks.
Interpret findings against applicable standards, limits and benchmarks.
Discuss preliminary findings with your team and refine conclusions where needed.
Prepare a clear, regulator-ready report with findings, evidence and recommendations.
Support implementation of recommendations and respond to regulator or client queries.
