18" Filter Assembly Performance The RainDrain system allows rainfall and water from other sources to be discharged from the berm. The filtration unit stops all target contaminates, acting as a hydrocarbon selection unit and reducing the dis- charged water below 10 ppm hydrocarbon content.

It is still possible that a small amount of fuel will escape through the RainDrain because of the higher fuel to water discharge ratio. This discharge can be trapped in a small discharge pit filled with hydrocarbon absorbent pads.
Drain Installation To install a RainDrain, the existing berm must be equipped with a drain. If your berm already has a drain, please see the information on Filtration Unit Installation. If no drain is present, or if the drain is not at a low point, a bulkhead fitting can be installed.

The filtration unit must be assembled in the following order, beginning at the berm’s bulkhead fitting: Remove the ¾" (19 mm) plug and install the ¾" (19 mm) close nipple into the bulkhead. Attach the valve and sight glass assembly to the ¾" nipple in the bulkhead. We Engineer Solutions RainDrain Operations Manual (Version D)

• Alaska State AAC-75.075 The RainDrain is designed to produce a discharge of water that does not contain more then 10mg/L of free oil and grease as measured by the partition-gravimetric method. Independent testing has proven the Rain- Drain exceeds this performance requirement and those results are available upon request.
