IM-Series tanks for septic, pump and potable water applications from Infiltrator Water Technologies are designed to be lightweight, durable, watertight and strong. The two-piece tanks are available in a variety of sizes including the IM-540 pump tank, the large-capacity IM-1530 septic tank, and the IM-1760C potable water tank. Enabling a wide range of installation options including shallow, multiple and serial tank configurations, tanks have integral heavy-duty lids that interconnect with the TW Riser System. They have structurally reinforced access ports, reinforced structural ribbing and fiberglass support posts for added strength. Inboard lifting lugs make delivery and handling easy. No special installation, backfill or water-filling procedures are required, and tanks can be pumped dry during pumpouts. The two-piece design nests for efficient shipping and reduced freight costs. 800/221-4436; www.infiltratorwater.com.
