Petro-Plugs® are used for oil containment at this hydroelectric dam.
Petro-Plugs are used for oil containment on the deck of this hydroelectric dam. There are 79 drains that drain into the river below.
The drains have large sumps that can be cleaned; the mounting rings are attached with construction adhesive. The Petro-Plugs will then slide into the opening, twist and lock. The o-ring in the Petro-Plug provides a seal that prevents any leakage. All water and oil must flow through the Petro-Plug.
The Petro-Plug is installed in the drain.
Filter floss is the next layer to control dirt, debris and sediment.
Next is a filter mat that is replaced as needed when full of dirt.
Finally the grate is replaced. The Petro-Plug is working 24/7 to protect the drain from oil spills.
