Applications -Flexible Membrane Floating Covers

Floating Cover System

Floating Cover with sand tube straps.

Flexible membrane floating covers have been performing well for over 20 years.

The low initial cost and easy upkeep of a floating cover makes them a very practical choice for potable or wastewater liquid storage and a strong asset in tandem with a flexible membrane liner under the cover.

Advantages to an Enclosed System

Cleaner Water — the liquid is completely encapsulated by geomembrane, keeping it consistently cleaner.

Greater Chemical Stability — the liquid is kept more chemically stable - for potable water, this means less chlorine use.

Consider Design:

There are several different design "types", however, the most common design in use is the Defined Sump, Tensioned Plate.
Pioneered by Burke Industries (Burke/Mercer), of San Jose, CA.

How it works:

Place the cover material in the bottom of the reservoir, tank or cell and attach it to any structures.
Place sand tube weights down the center of the of the containment structure and out into the corners.
These weights will force all of the 'slack' (when the cover rises with the water) into sumps, which will also capture and help drain off rain water later.
The weights cause the cover 'plates' to be in tension forcing the rain water to the sumps as well as allowing you to walk all over the covered area.
Covered foam floats are added parallel to the weights just outboard of the sump area for safety and other places for common walkways.
Access hatches, air vents, and sump pumps are added into the design criteria as needed.

Life expectancy of this cover exceeds 20 years.

Consider Installation

Construction of a floating cover is a craft. Experience, ability and pride of workmanship are all key ingredients along with certified technical ability and a commitment to Quality Control.

Maintenance

Although overall maintenance is low, we advocate routine inspections and periodic cleaning.
(the amount of time between cleanings is dependent upon the cover's location.)
