The EZsnap Riser from Infiltrator Water Technologies is an easy-to-assemble, watertight riser system for septic tanks, pump tanks and cisterns. The modular sections and click-and-lock technology allow riser height to be customized for any installation and create a watertight gasket-to-gasket seal. Made from polypropylene, the risers can be used with either concrete or plastic tanks and are available in 2-, 6-, and 12-inch sections with a 24-inch diameter that can be nested for efficient transportation. The slip-resistant lids are fastened using stainless steel screws and can withstand a wheel load comparable to the weight of a full-size pickup truck. The system also includes a safety lid that provides secondary protection if a primary riser lid is damaged or removed. 800-221-4436; www.infiltratorwater.com.
