The Norwesco Florida Only 525 Gallon Plastic Septic Pump Tank is a green polyethylene pump tank configured for Florida septic systems, where a dedicated pump chamber moves effluent from the treatment tank to a drainfield, mound, or dosing field. It holds 525 gallons, stands 59 inches tall, and sits on a square 64 x 64 inch footprint, so it drops into a standard excavated pit without an oversized hole. A single 20-inch lid is the only factory opening, giving you riser and access room for the pump, float tree, check valve, and discharge plumbing.
Will it work for your system?
This is the Florida-specific configuration of the Norwesco 525, so spec it for installs governed by Florida onsite-sewage rules. The single 20-inch lid (see the technical drawing on this page) is your sole service point, so the pump, floats, check valve, and discharge riser all have to stage through that one opening - lay out your rail and float tree to land inside it for future maintenance. There are no factory inlet/outlet bulkhead fittings or lid gasket listed for this configuration, so plan to field-supply your grommets, bulkheads, and seals rated for effluent service. Before you dig, confirm the chamber against your designed dose volume and pump cycle - the Tank Sizing Calculator and Tank Sizing Guide on this site walk through how working volume, drawdown, and reserve capacity stack up so the 525 matches your dosing requirement instead of guessing.
Plan for the filled weight and the empty float risk
Empty, a poly pump tank is light enough to set by hand or with a small machine, but your excavation and bedding have to be planned around two different load cases. Filled with water this tank carries roughly 4,378 pounds, so level, compacted bedding under the full 64 x 64 inch footprint keeps the lid, inlet, and outlet at design grade. The flotation risk, though, is the opposite case: an empty buried tank in Florida's high water table wants to float, and that filled-water figure does nothing to resist it. Size your anti-flotation ballast, deadmen, or backfill for the empty condition, not the loaded one. The 59-inch height is the tank body alone - confirm your bury depth and riser stack against that number plus whatever riser height you add to reach grade.
The mistake to avoid
The most common error on a septic order is assuming any tank is approved everywhere - it is not, which is exactly why this is the Florida-only version. Verify the model against your county health department's accepted-products list as part of permitting. A second guardrail: the specific-gravity rating on this model is listed as "No," meaning it is configured for effluent (septic) service and is not rated for elevated specific-gravity or chemical-storage liquids. Do not try to repurpose it as a chemical vessel - if you need chemical storage, spec a specific-gravity-rated chemical tank instead. If your project crosses into Canadian scope or you are comparing listings, our guide on Norwesco IAPMO and CSA B66 septic tank approvals covers cross-border code scope.
