GTI’s structurally supported covers are the perfect fit for wastewater treatment plants worldwide. The covers consist of a high-strength, retractable sheet of coated fabric tensioned across a low-profile aluminum arched frame that spans the tank opening.

GTI’s retractable covers effectively control odor while still providing easy access for inspection, sampling and maintenance. The airtight design reliably captures odorous offgases, yet disconnects and retracts easily, simplifying plant operations.

The covers are extremely durable and can yield significant cost savings. Each cover is custom-designed to meet the unique needs of the plant, and includes options for built-in walkways, hatches and guardrails.
