Tank Covers

Defender™ Tank Cover

Environetics’ Tank Covers provide an attractive solution for enclosing new or existing tank systems. Ideally suited for odor containment and algae control applications, Environetics’ Tank Covers are built to offer a cost effective alternative to aluminum or fiberglass roofs. Our unique mechanical attachment system provides a positive seal for effective odor containment. An attractive low profile design reduces internal volume, decreasing treatment system requirements. The proven geomembrane cover material has provided decades of service in the wastewater industry. Its opaque, light blocking, characteristics virtually eliminate UV light from the tanks for effective algae control.
