The Snyder Industries 500 Gallon Plastic Septic Pump Tank (SKU SII-PT2S) is a 500-gallon black polyethylene tank built for the pump-chamber side of a septic system, where effluent collects before a pump moves it on to the drainfield, mound, or downhill distribution point. Dig specs at a glance: a 60 x 60-inch square footprint, 63 inches tall, and roughly 4,170 pounds when filled to capacity with water. That loaded figure - not the much lighter empty handling weight - is the number to plan excavation, bedding, and anti-flotation ballast around, because a buried tank spends its working life full.
Will it work for your install?
This is a polyethylene pump tank, not a treatment or distribution component, so it earns its place as a dosing or pump chamber sized at 500 gallons. The 60 x 60-inch base and 63-inch height give you a compact square setup that drops into a standard excavation. The pump, floats, and alarm controls - plus the inlet and outlet penetrations - are set by your approved plan and confirmed on site, so they determine your real working volume rather than the nominal 500 gallons. Run the numbers with the Tank Sizing Calculator and the Tank Sizing Guide to confirm 500 gallons matches your pump cycle, reserve, and alarm volumes before you commit to a hole this size.
Approvals and code: confirm before you bury
Septic approvals are jurisdiction-specific, and a tank accepted in one state or province may need a different listing across a code boundary. Before installing, verify this tank against your local plumbing and onsite-wastewater code. Two reads worth your time: Norwesco IAPMO and CSA B66 Septic Tank Approvals for how cross-border scope works, and our Norwesco vs Snyder Industries manufacturer comparison if you are weighing build differences between the two makers. The broader manufacturer comparison buyer guide covers the wider field.
The mistake to avoid
The common error on a pump tank is treating it as a standalone septic tank. This is a pump or dosing chamber sized at 500 gallons; it is one stage in a designed system, and the pump, floats, and alarm controls determine your real working volume. Match it to a pump-tank role on an approved plan rather than back-filling a design around the tank you happen to have, and size your bedding and ballast around the 4,170-pound loaded weight so a buried, water-filled tank holds its place.
This tank ships LTL freight from the nearest Snyder plant to you - Chowchilla, CA; Marked Tree, AR; or Philippi, WV. That west, mid-south, and east coverage usually means a shorter LTL lane and a friendlier number for most ZIPs, since freight is quoted live to your destination.
