Open top storage tanks remain a common feature across industries such as water and wastewater treatment, chemical processing, and bulk liquid storage. Often part of original site designs, they continue to perform their role without much reconsideration. However, leaving tanks exposed introduces challenges that can go unnoticed day to day.

Rainwater, debris, temperature fluctuations, and airborne contaminants can all enter the tank, gradually impacting product quality, process efficiency, and overall performance. While not always immediately visible, these effects build over time and can become significant.

As highlighted by Ben Adamson, open tanks in refineries, chemical plants, and industrial facilities may appear secure, but exposure creates real risks. Rain can dilute stored products, while dust and airborne particles increase contamination and strain on filtration systems. Wind, sunlight, and temperature changes can further affect sensitive materials, while wastewater facilities face reduced efficiency due to debris and organic matter entering tanks.

These challenges are not just theoretical. Even minor contamination or evaporation can lead to operational inefficiencies, increased maintenance, odour issues, and potential regulatory concerns—ultimately impacting costs, safety, and uptime.

To address this, many operators are turning to geodesic tank domes. These structures provide a durable barrier against environmental exposure, protecting tanks from rain, dust, and debris. Their lightweight yet strong design makes them ideal for large-diameter tanks and retrofit applications.

By covering tanks, geodesic domes help maintain product quality, reduce evaporation and odours, and improve overall operational efficiency. As Adamson suggests, protecting storage tanks is no longer just a “nice-to-have,” but a practical step toward safer, more reliable operations.
