The Snyder Industries 500 gallon low profile septic tank delivers 500 gallons of single-compartment holding capacity in a footprint built to fit where standard upright septic tanks won't. At 42 inches tall on a 48 x 97 inch footprint, this green polyethylene tank slides into low-clearance installs, shallow burial setups, and tight side-yard runs where vertical height is the constraint. It ships preplumbed with the outlet already integrated, so you spend less time fitting it on site.
Will it work for your install
This is a one-compartment low profile septic tank, and here is what's plumbed from the factory: a 4-inch outlet, a sealed lid, and a 20-inch manway opening. The manway is the working entry point for inspection, service, and pump-out, so plan your access grade around it. Full of water this tank carries roughly 4,170 pounds, so your pad, bedding, and any anchoring need to account for that loaded weight, not the empty shell. Before you dig, confirm three hard numbers against your site: the 48 x 97 inch footprint, the 42-inch height, and the factory-set outlet and manway orientation shown on the technical drawing on this page. If you are sizing capacity against household or system flow, the Tank Sizing Calculator and Tank Sizing Guide walk you through matching gallons to your application.
The mistake to avoid
Low profile septic tanks live and die by the install. Because the tank is wide and short rather than tall, it presents more surface area to buoyant forces if your water table is high, and it can shift or float during a heavy rain event before backfill is settled if it is set empty. Fill it as you backfill, and confirm your local approval before you commit, septic approvals are jurisdiction-specific and not all codes treat low profile or polyethylene tanks the same way. If you are crossing into Canada or comparing US plumbing-code scope, our guide on septic tank approvals (IAPMO and CSA B66) lays out where those approvals do and don't carry across the border.
Freight
That ~4,170-pound loaded weight is also the number that drives freight class, so it pays to get a real quote early, use the Freight Cost Estimator for a number to your ZIP. This tank ships LTL freight, quoted live, and it's produced at Snyder plants in Chowchilla, CA, Marked Tree, AR, and Philippi, WV; we ship from the location nearest you to keep freight down. You can also call us at 866-418-1777 and we'll quote it for you. If you're planning a multi-tank septic or holding setup, the guide on multi-tank manifold design covers header and common-drain layout for two-, four-, and eight-tank systems.
