Increasing EPA regulations, insurance providers and industry developments (LEED) are demanding tighter pollution controls in the area of groundwater quality. In areas of environment concern and/or when handling particularly noxious chemicals a fail-safe double containment drainage system may be necessary.

There are several double contained pipe systems and small catch basins available. These systems do not offer the collection and catchment performance benefits of using a trench drain system. Aquaducts’ double contained trench system is two fiberglass trench drains assembled inside one another with a space where any leaks will collect.

Aquaduct offer a double contained trench system with several leak detection options:

	Leak detection ports - allows visual detection, positioned at various low points around the system.
	Leak sensors - the trench can be adapted to incorporate an electronic sensor system.

Should a leak occur, because the entire trench is accessible from ground level a full repair is usually possible without removal of the system. Trench sections up to 40 feet are common with double containment trenches as joints are easier to seal in the factory, however field joints are almost always required and Aquaduct’s field service technician will be available on site to seal these joints to guarantee a fail-safe system.
