Floating Cover Systems

IEC's Floating Covers are customized for each client’s lagoon or tank size and shape.

A series of lateral floats provide pathways for gas to flow underneath to the perimeter collection pipe and on to a single collection point. The lateral floats keep the entire cover floating on the waters’ surface, and eliminate cover inflation, and exposure to wind damage.

Floating covers that inflate (without lateral floats) expose the geomembrane cover to vibration and geomembrane fatigue from wind constantly blowing over the inflated cover. This significantly reduces the life span of the cover.

Ballast weights on top of the floating cover channel rainwater and snow melt to sumps to remove all rainwater from the surface of the floating cover.

Floating cover applications:

• any type of gas collection from water basin

• keep rain & snowmelt water separate from wastewater under the cover

Floating cover advantages:

• provide a true “floating” cover, keeping the cover on the water surface avoiding damage from wind due to an inflated cover without lateral floats

• accommodate fluctuation in water level

• can be installed without interruption in basin use

• can be installed on tanks or lagoons

• eliminates rainwater pooling problems

• eliminates inflating the cover and gas ballooning

• hatches provide access under the cover for equipment

Testimonials

• "We have been working with IEC since 2006. In that time IEC has supplied and installed 10 gas covers and 5 pond liners spread out over 7 different dairies. The ponds they have worked on range in size from 52,000 Sq. Ft., to over 450,000 Sq. Ft.

  Over the years IEC has been very responsive to our changing installation needs. They have worked with us to develop access points for floating pumps, and responded quickly to requests for modifications to our lagoon systems."

• Lemna Technologies, Inc. is an engineering and equipment supply company involved with wastewater treatment projects. Lemna has contracted with Industrial & Environmental Concepts over the past 15 years to design, fabricate and install floating covers and liners for our turnkey projects and customers for a multitude of wastewater applications worldwide.

  Their staff has done an excellent job in providing Lemna with support at the design phase of our projects. We have then had Industrial & Environmental Concepts fabricate all of our floating cover materials, which were delivered on a timely basis. Lastly we have had their field crews install many of our modular covers; and all of our gas collection covers and liners.

  I have been very satisfied with Industrial & Environmental Concepts as a supplied and look forward to working with them in the future.
