bund

The most important of these [secondary containment] provisions are bunds, which are enclosures capable of holding liquids that may escape from the vessels and pipes within the bund wall.

It is pleasant to see the Chinese domestics and their families; or native ladies dressed in silks, their glossy hair held in by a broad black velvet band with a spray of pearls in front, being propelled along the bund in their hand-carts; but they are not used among Europeans, excepting after dark.
