Specifications at a Glance
Every figure below is pulled straight from the live product record for this exact tank — the same data on the product page, so what you read here and what you buy never disagree.
Standards & Materials
- ASTM D1998 — Standard Specification for Polyethylene Upright Storage Tanks. Governs wall-thickness and hydrostatic design for vertical rotomolded poly tanks of this class.
- FDA 21 CFR 177.1520 — Olefin polymers. The food-contact regulation the FDA-grade resin in this tank is compounded to meet.
- Specific gravity rating 1.1 — the tank is engineered for liquids up to 1.1× the density of water (water is about 8.34 lb/gal). Confirm your fluid’s SG before storage.
Installation and Setup Guide
This 3,000-gallon tank stands 93 inches tall on a broad 102-inch base, and full of water it carries roughly twelve tons. The green pigment sets it apart visually — chosen to blend into landscaping and garden settings rather than disappear behind a barn — but structurally the rules are the same as any large water tank: the foundation makes or breaks the installation.
The Pad
Build a reinforced concrete slab or a deep, compacted gravel pad sized for the full loaded weight and leveled across the wide 102-inch diameter. A broad base means a large area to keep flat, so screed it carefully and verify with a long straightedge from several angles. Place it on draining ground, clear of rocks, and slope the surrounding grade away so water never undermines the pad.
Placement and Plumbing
Leave about three feet of working clearance around the tank for fills, inspection, and service. Run the outlet in schedule 80 PVC, keep the first foot of each connection flexible to take up the polyethylene's seasonal movement, and carry every pipe on its own support. Fit an isolation valve so the tank can be shut off for maintenance without draining.
Venting
Air must move in and out as fast as water does. Install a screened vent in the lid sized to your peak fill and draw rates so the tank never pulls a vacuum on a hard pump-down. The screen keeps debris and insects out of the stored drinking water while letting the tank breathe.
Maintenance and Long-Term Care
This is a potable tank, so it gets real water maintenance. One thing to note with a green tank: green pigment lets a little more light through than black, so algae control through regular turnover and annual cleaning matters more here than on a black tank.
Inspection
- Foundation: Check the wide slab and surrounding ground for cracking or settlement several times a year, since twelve tons across a broad base will find any soft spot.
- Wall and water clarity: Walk the wall for bulging and, with the lighter green color, glance at the water clarity through the lid — any tinge of growth means it is time to clean and turn the supply over.
- Fittings and vent: Hand-snug the outlet if it has loosened and keep the vent screen clear.
Annual Sanitizing
Drain the tank yearly, flush the floor sediment, and disinfect before refilling using the potable standard — a quarter cup of unscented bleach per fifteen gallons, held two hours, then drained and rinsed until the chlorine smell is gone. Because green admits some light, consider running this cycle a touch more often if you ever notice growth.
Sun and Frost
The resin still carries molded-in UV protection, so the green wall holds up outdoors; check the sun-facing side yearly in harsh climates. In freezing weather, keep the tank turning over or drain it, as a full tank that ices can crack.
Alternatives and Comparisons
At 3,000 gallons the standout choice here is color, and green is a deliberate, landscape-friendly option.
Green vs. black: The green pigment helps the tank recede into gardens, yards, and natural settings where a stark black tank would draw the eye. The trade-off is light: black blocks sunlight most completely and gives the strongest algae suppression and UV durability, while green admits a little more light and benefits from slightly more attentive cleaning. On footprint, this tank's 102-inch base and 93-inch height sit on the broad-and-stable side, easy to fill and inspect; a taller vertical of the same volume saves ground and adds outlet pressure.

Frequently Asked Questions
How long will the 3000 Gallon Plastic Water Storage Tank - Green (102" x 93") last?
On a level, well-built base and used as a water tank within normal polyethylene temperature limits, this tank readily reaches 15 to 20 years. The resin carries molded-in UV protection for outdoor service, and the seamless shell has no joint to fail. With the green color admitting a little light, an annual drain-and-sanitize and regular turnover keep both the water and the tank in good shape.
What chemicals can I store in this tank?
It is an FDA-approved potable-water tank for drinking water, livestock, and irrigation, plus water-based liquids within its rating. It is not built for fuels, solvents, or aggressive chemicals. For chemical storage, choose a dedicated 1.5-SG liquid tank and check the product against a compatibility chart — a water tank is not the right vessel for chemistry.
Does this tank come with a warranty?
Yes. Norwesco provides a 3-year warranty for manufacturing defects in materials and workmanship under normal-use conditions. The coverage is for molded-in faults, not damage from a poor foundation, overfilling, incompatible chemicals, or impact. Save your receipt and a photo of the completed installation.
Can I install this tank underground?
No. The vertical wall is not engineered to withstand soil pressure, so burying this tank risks collapse and voids the warranty. For storing water below grade, our reinforced underground cisterns are the right choice.
Buying Considerations
Three things before this 3,000-gallon green tank ships. First, the base: a level slab or deep compacted pad better than eight and a half feet across, sized for about twelve tons full. Second, your plumbing — confirm the outlet thread and have schedule 80 fittings ready. Third, freight, the big consideration: it ships oversized on a dedicated truck and needs a forklift to set. The green color is the visual draw if you want the tank to blend into a landscaped setting. Listed at $2,420.00 before freight, quoted to your ZIP.
