An Illinois utility used the EVAC Filtration System to assist in the dewatering of vaults and manholes in the City of Chicago and surrounding suburbs. The EVAC System uses state-of-the-art filtration technology to remove suspended solids and light sheen from water discharge operations.
When a frac tank full of oily waste had to be emptied, the EPA used the EVAC Filtration System to dewater it. Not only were hydrocarbons captured and sediment removed, the EVAC System cost only a fraction of the use of a vacuum truck, saving thousands of dollars.
Concrete containment is a fairly common permanent solution used by utility companies to prevent a transformer oil leak from polluting the ground, and offers some obvious benefits when used for secondary containment. It is strong and durable, and requires low maintenance. It has a long life expectancy and is fire-resistant.
We all want to do our part in taking care of this wonderful, sustainable eco-system known as Earth. As Halloween approaches and a kaleidoscope of colorful leaves slip toward the ground, we are reminded that our time wandering over her landscapes will be brief, in the grand timeline of the universe, but that doesn’t mean we should be inconsiderate as we pass through. As humans, limiting or minimizing the ecological footprints we create should be something we strive to do. After all, are we not but caretakers of our great-great-great-great grandchildren’s home?
