IM-Series Tanks for septic, pump and potable water applications from Infiltrator Water Technologies are lightweight, durable, watertight and strong. The two-piece design is 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. A wide-range of installation options are available, including shallow, multiple and serial tank configurations. The tanks feature integral, heavy-duty lids that interconnect with watertight click-and-lock EZ Snap Risers or the TW Riser System. They have structurally reinforced access ports, reinforced structural ribbing and fiberglass support posts to provide additional 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 tank design nests easily for efficient shipping, reducing freight costs. 800/221-4436; www.infiltratorwater.com.
