Abstract: A sump for inhibiting leakage of liquid includes a double wall for at least part of the sump, and an interstitial space between the double wall. An indicator liquid is located in the space, and a sensor is in fluid communication with the space such that a change in the pressure or liquid level in the interstitial space causes the sensor to indicate leakage into or from the interstitial space. The double wall includes a base, a wall directed upwardly from the base of the sump, and the upwardly directed wall includes an angular portion being directed at an angle from the base greater than 90 degrees relative to the base. A remote location of that portion is connected with a substantially upright wall portion for the sump. An aperture for an electrical conduit is located in the angular portion.

The sealing flange is held against the wall by a backing ring placed against the outside wall of the box. The backing ring includes a plurality of studs extending through the wall and into the box. A compression ring with a plurality of holes is placed over the sealing flange with the studs of the backing ring extending though the holes. A plurality of nuts are threaded to the studs to hold the sealing flange firmly against the inside wall of the box. The flexible boot also includes a sleeve for providing a second seal against the outside surface of the pipeline. The sleeve is stepped with different sized openings so as to be able to receive different sizes of pipelines.
