AWWA Leachate Storage Tanks from the Factory

An AWWA leachate storage tank is a bolted vessel built to AWWA D103-09 that holds landfill leachate at pH as low as 1, and the proven linings are Glass-Fused-to-Steel or Fusion Bonded Epoxy. Engineered by Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), each panel is holiday-tested at 1500 V and the shell is calculated to ISO 28765 for a 30-50 year containment life.

What an AWWA Leachate Tank Is

An AWWA leachate storage tank is a bolted steel vessel built to AWWA D103-09 whose lining resists landfill leachate at pH 1-14. The Glass-Fused-to-Steel version carries a 0.25-0.45 mm enamel fused at 820-930 C, while the Fusion Bonded Epoxy version carries a 250-450 um coat, both holiday-tested at 1500 V for a 30-50 year containment life.

• Code: AWWA D103-09.
• pH: 1-14 range.
• Coat: enamel or FBE.
• Life: 30-50 years.

How the Tank Resists Acid Leachate

The seal relies on a pinhole-free lining verified at 1500 V per panel and 8.8-grade bolts with gaskets that keep the acidic leachate away from bare steel. Because the enamel is inert at 6.0 Mohs hardness and the FBE resists pH 1-14, the 30-50 year shell keeps its tightness while the leachate pH swings from below 2 to alkaline. The factory test record is the proof.

• Test: 1500 V panel.
• Bolts: 8.8-grade gasket.
• pH: 1-14 tolerant.
• Hardness: 6.0 Mohs.

Key Types, Components, and Features

The family covers the GFS leachate tank and the FBE leachate tank, each with 8.8-grade bolting and a fixed or membrane roof. Core parts are the coated panels, the manways, the leachate nozzles, and the level instruments. A documented AWWA D103-09 and ISO 28765 calculation and a 1500 V holiday test are the features that qualify the tank for hazardous leachate.

• GFS: enamel lining.
• FBE: epoxy lining.
• Bolts: 8.8-grade.
• Test: 1500 V holiday.

Applications of Leachate Tanks

They serve landfill sites, transfer stations, and remediation projects where the leachate pH can fall below 2 and attack painted steel. A 30-50 year GFS or FBE tank is also used for leachate equalization and treatment buffer on the same site. The inert lining is why the same tank family covers both acidic and alkaline leachate.

• Landfill: leachate duty.
• Remediation: buffer tank.
• Equalization: treatment feed.
• Acid: pH below 2.

Technical Considerations

Technically the steel is blasted to Sa 2.5, the lining is fused or cured to 0.25-0.45 mm enamel or 250-450 um epoxy, and each panel passes a 1500 V holiday test before shipment. The shell is calculated to AWWA D103-09 and ISO 28765, the bolt torque is recorded, and an inspection package covers every step. Design life runs 30-50 years with routine gasket checks.

• Blast: Sa 2.5 anchor.
• Coat: 0.25-0.45 mm / 250-450 um.
• Test: 1500 V holiday.
• Life: 30-50 years.

How to Select an AWWA Leachate Tank

Select by matching the leachate pH (confirm below 2), the storage volume (20-60,000 m3), and the lining to a GFS or FBE tank with a documented 1500 V test and 8.8-grade bolts. Ask the supplier for the AWWA D103-09 and ISO 28765 calculation, the holiday-test record, and the reference landfills. Reject any offer that cannot show the lining thickness certificate.

• Confirm: pH below 2.
• Match: volume and lining.
• Demand: 1500 V record.
• Verify: ISO 28765 math.

Project Case Study

A verified landfill leachate project in Guangxi, China used two 3,376 m3 Glass-Fused-to-Steel (GFS) bolted tanks built in 2022 to store acidic leachate with enamel roofs. The 0.25-0.45 mm enamel coat was holiday-tested at 1500 V and the 8.8-grade bolted seams held the structure, demonstrating an AWWA D103-09 leachate tank on a real landfill.

About Shijiazhuang Zhengzhong Technology Co., Ltd.

Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) operates quality-controlled coating lines for both Glass-Fused-to-Steel and Fusion Bonded Epoxy panels, founded in 2008 and exporting to more than 100 countries. Its leachate program is documented under ISO 9001 and verified at 1500 V per panel, giving landfill operators a traceable lining certificate for pH 1-14 duty.

• Founded: 2008 in China.
• Coatings: GFS and FBE.
• QC: ISO 9001.
• Test: 1500 V per panel.

Advantages and Limitations

Advantages are the 1500 V-verified lining, the pH 1-14 tolerance, and rapid bolted erection that avoids field welding. Limitations are that the exact leachate chemistry should be confirmed and the site must provide a level foundation and secondary containment. The tank is not for bulk hydrocarbons.

• Pros: pH 1-14.
• Pros: 1500 V seal.
• Limit: confirm chemistry.
• Limit: secondary bund.

Comparison of Leachate Linings

Against painted welded steel, the GFS or FBE lining wins on 30-50 year corrosion life and a 1500 V-verified seal; against concrete it wins on speed and weight. The table contrasts the common materials for leachate duty so the choice matches the pH and the budget.

• GFS: enamel lining.
• FBE: epoxy lining.
• Welded: shorter life.
• Concrete: slow build.

Conclusion

An AWWA leachate storage tank is defined by a lining verified at 1500 V, an AWWA D103-09 shell, and a 30-50 year containment life for pH 1-14 leachate. Specify the lining, demand the holiday-test record, and the tank will hold acidic leachate without coating loss.

• Spec: AWWA D103-09.
• Verify: 1500 V test.
• Confirm: pH range.

Frequently Asked Questions (FAQ)

What is an AWWA leachate storage tank?

It is a bolted steel tank built to AWWA D103-09 with a Glass-Fused-to-Steel or Fusion Bonded Epoxy lining that resists landfill leachate at pH 1-14 for a 30-50 year life.

What pH can it handle?

The GFS enamel and the FBE epoxy both tolerate pH 1-14; always confirm the exact leachate chemistry, especially when the pH falls below 2.

What capacity is available?

Single bolted tanks range from 20 m3 to 60,000 m3, and larger leachate systems use multiple parallel tanks.

What standards apply?

The shell follows AWWA D103-09 and ISO 28765, the lining is verified at 1500 V, and the program is documented under ISO 9001.

How is it installed?

Panels are bolted on a prepared foundation by local crews under supplier supervision; no interior field welding protects the lining.

Is it suitable for landfill leachate?

Yes. Landfill and remediation leachate is a documented application; the inert lining resists the acidic, sulfide-rich stream.
