Septic tanks in fiberglass and plastic have been around for years. Experience in the field has taught manufacturers new tricks in making those tanks strong, long-lasting and leak-free. Here are some of the latest innovations in septic tanks, pump tanks and tank accessories now available to innovative installers.
Low-profile Tanks
The Dominator from Snyder Industries is a new line of low-profile septic tanks. A monolithic structural design provides high top-load strength, and a proprietary manway isolation design keeps manholes from distorting during backfill and pump-outs. The tanks require no special water-filling procedures during backfill and can be used in both septic and pump tank applications. The septic tank is available pre-plumbed with inlet and outlet tees preinstalled. The unit is available in 750-, 900-, 1,050-, 1,250- and 1,500-gallon capacities and in single or double compartments. 402/467-5221; www.snydernet.com.
Seamless Design
High-performance polyethylene septic tanks from Premier Tech Environnement have a seamless design that makes them airtight and watertight, eliminating water infiltration or leaks and minimizing odors. The easy access for inspection and servicing ensures compliance with government standards and requirements. 800/632-6356; www.ptenv.com.
Rust-resistant
Rust-resistant fiberglass septic tanks from Containment Solutions are IAPMO-approved and range from 4 to 12 feet in diameter. The tanks are manufactured using a premium resin, glass fibers and a specially treated silica that results in a composite matrix suitable for nonpotable water applications. The rib design adds strength and durability. The tanks, with single-, double- or triple-wall construction, range from 600- to 50,000-gallon capacities. 800/537-4730; www.containment solutions.com.

They are manufactured to applicable requirements of UL 1316 and ANSI/AWWA D120-02. The tanks are available in single-, double- or triple-wall models. Sizes range from 600 gallons to more than 60,000 gallons. 952/887-1890; www.xerxescorp.com.
