Section 1: Introduction to the RainDrain System
Overview
The RainDrain system allows operators to continuously gravity-drain rain water from secondary contain-
ment berms without having to monitor the discharge. The RainDrain is designed as a go-no-go filtration
system that will automatically stop the flow of discharge water when it is full or when there is a large amount
of hydrocarbons present in the water being discharged.
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.
When the filtration unit reaches containment capacity, it will automatically cease to discharge all fluids.
When this occurs the filter cartridge will have to be replaced. Once that is completed, the system is ready
for normal operation.

Important Note
The amount of hydrocarbons present in the secondary containment system will determine the
frequency in which to replace the filter cartridge.

Warning
In the event of a catastrophic failure of a primary containment tank (that is secured within a
secondary containment berm and protected by the RainDrain), the subsequent spill of a significant
amount of fuel will cause the filter to shut down automatically. 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.
Important Note
The RainDrain is designed to limit discharge contamination to below 10 mg/L total extractable
hydrocarbons at an inlet contamination level of 1% or less fuel in water.
For fuel levels above 1% solution, the RainDrain will seal but some contaminants will be
discharged above 15 parts per million free oil.

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. To install a bulkhead fitting, please follow this procedure:
1. Cut a 1¼" (3.25 cm) hole in the berm wall.
2. With the rubber washer on the body, insert the fittings
body through the hole from the inside of the berm.

3. Attach locking nut and tighten firmly.
4. The installed fitting should now look like this.

Filtration Unit Installation
The filtration unit must be assembled in the following order, beginning at the berm’s bulkhead fitting:
1. Remove the ¾" (19 mm) plug and install the ¾" (19 mm) close
nipple into the bulkhead.
2. Attach the valve and sight glass assembly to the ¾" nipple in the
bulkhead.

3. Attach the black hose and filtration canister to the
sight glass assembly.
4. Install the leaf guard on the inside of the berm.
