Managing rainwater on open-top floating roof tanks has long required operators to choose between two imperfect options. Until now, there has been no reliable way to remove accumulated storm water without introducing additional risk.

If roof drain valves are left open, rainwater drains freely from the roof during light or severe weather. However, a failure within the internal drain line can allow stored product to escape through the drain, resulting in an unintended release into the tank dike.

If roof drain valves are kept closed, operators must manually intervene during rain events. Delayed response or excessive water accumulation can compromise roof buoyancy, potentially leading to roof damage, tank wall stress, and release of stored product.

In both cases, the consequences can include environmental contamination, permit violations, regulatory scrutiny, tank damage, and extended downtime.

EnviroEye eliminates this tradeoff by automatically detecting hydrocarbons and isolating the drain before a release can occur.
