v <br />Single-WallContainment Sumpoptions <br />For more than two decades, Xerxes single-wall containment sumps have <br />K." proven to be an effective method for providing secondary containment for <br />tank top fittings and the various tank accessories for which those fittings <br />are designed. These single-wall containment sumps have a successful track <br />record through thousands of installations in a wide variety of applications <br />and water -table conditions. Xerxes was an early pioneer in developing con- <br />tainment sumps specifically designed for use with Xerxes single-wall and <br />double-wall tanks and collars. A number of polyethylene and fiberglass <br />containment sumps designed by other manufacturers for use on Xerxes fac- <br />tory -installed collars have been introduced over the years. Some of these <br />products have since disappeared from the market or required replacement. <br />However, Xerxes containment sumps have an outstanding performance <br />record and provide customers the best overall solution for their contain- <br />ment needs. <br />Round and flat -sided models <br />The Xerxes single-wall containment sump is available in both round and <br />flat -sided models. Both the round and flat -sided sumps are designed to fit <br />a Xerxes round containment collar. For more than two decades, the <br />round, one-piece design has proven to work well in many applications <br />while still allowing for ease of installation. Some customers prefer the <br />new flat -sided, two-piece design, which allows customers to easily install <br />submersible pumps, and related piping and electrical connections from <br />outside the sump prior to final installation of the sump. Also, some cus- <br />tomers prefer flat -sided surfaces for securing watertight pipe and electri- <br />cal penetrations. The single-wall containment sump is also available in a <br />flat -bottom model that is affixed to the tank with an adapter (provided <br />by others). The flat -bottom containment sump model is typically used to <br />retrofit existing tanks. <br />Available in a round, one-piece model and a flat -sided, <br />two-piece model <br />Sump sizes <br />The single-wall containment sump comes in two diameters and a variety of <br />heights. <br />• Available in 42" and 48" diameters <br />• Available in different body heights <br />• Can be trimmed in the field after final sump elevation is set <br />• Available in deep -burial models <br />Cover options <br />Each single-wall model (round or flat -sided) has several top or cover <br />options.
