The Snyder Industries 300 Gallon Septic Pump Tank is a 300-gallon grey polyethylene tank built for the dosing and effluent-handling side of an onsite system, where wastewater collects before a pump lifts it to a drainfield, mound, or downstream treatment stage. It stands 53 inches tall on a compact 48.5 by 48.5 inch footprint, so it drops into a tight excavation while still holding a full working volume. Filled with water it weighs about 2,502 pounds - the number you need before you size the pad, the backfill, and the equipment that will set it.
Will it work for your install?
This is a pump tank, not a primary septic tank, so it is meant to receive effluent and house a pump, floats, and the associated controls rather than to handle raw solids settling. The vertical 53-inch height and square 48.5-inch footprint give you head room for a pump basin and float tree inside the access opening, but plan your excavation for the full 53-inch tank height plus the riser and lid stack-up that sit on top of it - underestimating that vertical clearance is the most common reason a septic install has to be dug back up. Fitting and access details matter here too: inlet, outlet, and access-opening sizes are not published in this listing, so confirm them from the technical drawing on this page or by phone before you match a pump, floats, and pipe to the tank. If you are still working out whether 300 gallons matches your dosing volume and reserve capacity, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide before you commit.
The mistake to avoid
This tank carries a specific-gravity rating of "No," meaning it is not assigned a contents specific-gravity rating for chemical or high-density liquid service. Treat it as a wastewater and effluent pump tank, not a chemical storage tank - there is no higher-SG version of this unit, and it should not be pressed into chemical duty. Septic and pump-tank installs are also code-driven: approvals, burial depth, and venting vary by jurisdiction, and an unapproved tank or wrong configuration is an expensive thing to dig back up. Before you buy, verify local acceptance, and if you are installing across the border or comparing approval scopes, read our guide on Norwesco IAPMO and CSA B66 septic tank approvals.

Freight and how to order
This 300 gallon Snyder septic pump tank ships LTL freight, quoted live to your ZIP from the nearest Snyder plant that stocks it - Chowchilla, CA; Marked Tree, AR; or Philippi, WV. Because stock location drives the LTL number more than anything else, confirm which plant actually has your unit before you trust an estimate. Keep that 2,502-pound full-water weight in mind not just for the pad but for rating the crane, excavator, or straps that will set the tank. Get an exact freight number for your address with our Freight Cost Estimator, or call us at 866-418-1777 and we will confirm the closest shipping point, lead time, and the right pump-tank configuration for your system.
