A 525 gallon green septic pump tank approved for Florida installs
The Norwesco 525 gallon septic pump tank, part number 44830, is the Florida-only version of Norwesco's larger buried pump chamber: a round green polyethylene tank 64 inches in diameter and 59 inches tall, weighing 174 lb empty. It sits after the septic tank and holds effluent for a submersible pump that sends it on to a drainfield, a mound or a drip field, with room for timed dosing and a real emergency reserve above the high float. Access is a 20 inch gasketed manway on top. Norwesco rates it to 130 F, lists its state septic approval as Florida, and backs it with a 3 year warranty. Norwesco's drawing is linked on this page under Technical Drawing. Full of water it holds about 4380 lb.

Where a 525 gallon pump tank fits
This is the pump tank for a larger home, a duplex, a small commercial system or any design where the engineer wants timed doses with hours of storage behind them: a drip field, a mound with equal distribution, or a treatment unit that must not be surged. The extra volume over the smaller pump tanks is mostly reserve, which is what keeps an alarm from becoming a backup when the power is out or the pump is waiting on a part. At 59 inches tall it still sets in a modest hole, and the 64 inch diameter is a one-day excavation with a compact machine. A pump tank stores and sends; it does not treat, so the dose and the cycle come from the county approval. For total system volume, use the tank sizing calculator and tank sizing guide. Our piece on how Norwesco's septic approvals are scoped explains how a state-specific listing differs from a national one.
What to check before you buy
- The state. Norwesco lists this model's septic approval as Florida only. Outside Florida, order the 500 gallon septic pump tank, which shares this footprint in a different shell.
- The manway. One 20 inch gasketed manway on top for the pump, the floats and the discharge line. Plan a riser to grade so the pump can be pulled without a shovel.
- Inlet and outlet. None are factory installed. The installer cuts the inlet and the discharge where the site needs them, with the seals the county requires. Tell us the pipe sizes and we will confirm what to add to the order.
- Temperature. Rated to 130 F, well above household effluent.
- Burial. Follow Norwesco's installation instructions for bedding and backfill, with water in the tank as you backfill. Keep it clear of drives and vehicle paths unless an engineered cover is in the design. A buried tank that is pumped empty in wet ground wants to float; keep water in it or follow the anti-flotation detail on the design.

Shipping and receiving
The tank ships LTL under NMFC 156600-02 from Norwesco's Griffin, Georgia plant, 64 by 64 by 59 inches on the pallet at 174 lb. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP. At 174 lb it comes off the truck with two people, a liftgate or a forklift; tell us which you have. Check 44830 against the bill of lading, look over the manway lip and the wall for transit damage, and keep the tank out of the sun until it goes in the ground.
