Retractable structurally supported covers from Geomembrane Technologies Inc. (GTI) are a proven way to contain foul odors resulting from wastewater treatment while providing easy access to tank internals. However, an open cover can present a potential occupational health and safety risk that needs to be addressed by plant staff and their engineers.
Treatment plant staff and their engineering advisors often inquire about ways to combine the easy access of a retractable cover with the increased safety that comes with a guardrail system. GTI has developed a patented clear-span guardrail for its retractable structurally supported covers in response to these requests.
GTI’s structurally supported covers consist of a high-strength, retractable sheet of coated fabric tensioned across a low-profile aluminum arched frame that spans the tank opening. This design effectively controls odor and algae while still providing easy access for inspection and maintenance.
GTI’s clear-span guardrail aligns with the end of GTI’s retractable covers and, for most covers, spans the tank width with no vertical posts. That means the cover can be easily rolled open and closed without interference from guardrail posts. The GTI guardrail is custom-designed to withstand code loads, just like standard guardrails.
