AWWA Standards For Bolted Makeup Water Storage Tanks: Understanding D103-19 And The "D153" Question

When a makeup water storage tank is specified 'to AWWA', the buyer should know exactly which AWWA standard applies, because the wrong reference creates confusion at inspection. The recognized AWWA standards for water storage are D100 (welded carbon steel), D103-19 (factory-coated bolted carbon steel tanks), D102 (coating of steel tanks), and D108 (aluminum dome roofs). This article explains what each covers, what D103-19 actually requires for a bolted tank, and - importantly - why a citation of 'AWWA D153' should be confirmed rather than assumed, because there is no AWWA 'D153' tank standard in the current published list.

AWWA's published standards for water storage are specific and named. D100-21 covers welded carbon steel tanks; D103-19 covers factory-coated bolted carbon steel tanks for water storage; D102-24 covers the coating and recoating of steel water tanks (including field work on existing tanks); and D108-19 covers aluminum dome roofs. Each has a scope, so the right reference depends on whether the tank is welded, bolted, being recoated, or getting a dome.

Citing 'AWWA' alone is not a specification; name the edition.

• D100-21 welded.
• D103-19 bolted.
• D102-24 coating.
• D108-19 dome.

A check of the current AWWA standards list shows no D153 standard for water-storage tanks (or for tanks generally). The numbers jump from D108 (domes) and D110/D115 (concrete/prestressed) to other families; D153 is not among them. Where a buyer or supplier writes 'AWWA D153', the safest move is to ask for the exact document: it may be a typographical error for D103, a standard from a different publisher mislabeled as AWWA, or a project-specific internal designation, but it is not an AWWA tank standard to specify against.

Assume nothing; confirm the document before quoting.

• No D153 in AWWA list.
• Likely typo for D103.
• Or non-AWWA ref.
• Confirm before quoting.

AWWA D103-19 sets the minimum requirements for design, fabrication, construction, inspection, and testing of new cylindrical, factory-coated, bolted carbon steel tanks at ground level. It governs the panel structure, the factory-applied coating systems (which can include GFS, FBE, galvanized, or thermoset systems), and the quality controls that make a bolted tank serviceable. For potable water, the lining must also carry NSF-61 product-specific certification. A supplier claiming 'AWWA' should show D103-19 compliance with the coating and NSF-61 evidence, not just the words.

D103-19 is the bolted-tank anchor; NSF-61 covers potable lining.

• Design + fabrication.
• Factory coating systems.
• NSF-61 for potable.
• Show evidence.

Write the standard and edition explicitly: 'AWWA D103-19' for bolted steel, 'AWWA D100-21' for welded, and 'NSF-61' for potable lining; add ISO 28765 and EN 1090 where international or EU projects demand them. Require coating thickness and holiday-test records (typically 1500 V for GFS/FBE), panel traceability, and a reference project. If a counterparty cites 'D153', ask them to confirm the document before you build it into the purchase order.

Name the edition; do not leave it open.

• Name edition in PO.
• NSF-61 potable.
• Holiday + traceability.
• Confirm any odd ref.

We have no makeup-water or data-center project in this library. The Indonesia Cilincing drinking-water tank (21,088 m3, 2024) is a real GFS water-tank delivery cited as analogous proof of building AWWA-aware bolted tanks, not a makeup or data-center delivery. The standard explanation above reflects the published AWWA list and D103-19 scope, not a specific makeup contract, and we explicitly do not claim a 'D153' standard exists.

• No makeup / DC project.
• Real coated tank 2024.
• Analogous, not claimed.
• No D153 claimed.

AWWA D103-19, Factory-Coated Bolted Carbon Steel Tanks for Water Storage - it sets design, fabrication, coating, and testing requirements for new bolted tanks.

No - a check of the current AWWA standards list shows no D153 tank standard; it is likely a typo for D103, a non-AWWA reference, or a project-specific designation, so confirm the document.

D100-21 covers welded carbon steel tanks for water storage, as distinct from the bolted-tank scope of D103-19.

Yes - where the water is potable or semi-potable, the lining must carry NSF-61 product-specific certification in addition to the structural AWWA standard.

It permits factory-applied systems including glass-fused-to-steel (GFS), fusion-bonded epoxy (FBE), galvanized, and thermoset coatings, each meeting defined performance criteria.

Not in our project library. We cite our real Indonesia drinking-water tank (21,088 m3, 2024) as analogous AWWA-aware capability, not a makeup or data-center project.

Name it explicitly with the edition, e.g. 'AWWA D103-19' and 'NSF-61', plus ISO 28765 or EN 1090 where international or EU projects require them.

Coating thickness and 1500 V holiday-test records, panel-ID traceability, and a verifiable reference project - not just the words 'AWWA compliant'.

Treat that as a red flag; require the specific edition and scope, because 'all AWWA' without an edition is not a verifiable specification.

A makeup water storage tank specified to AWWA should reference the standard that actually exists: D103-19 for factory-coated bolted carbon steel tanks, with D100-21 for welded, D102-24 for coating, and D108-19 for domes filling the rest of the picture, and NSF-61 for any potable lining. There is no AWWA 'D153' tank standard in the current list, so a buyer who sees D153 should confirm the exact document before building it into the order - it is most likely a typo for D103 or a non-AWWA reference. Center Enamel's real Indonesia Cilincing drinking-water tank (21,088 m3, 2024) shows we build AWWA-aware bolted tanks; the makeup or data-center application is analogous and not claimed. Name the edition, require the holiday-test and NSF-61 evidence, and the specification becomes verifiable instead of decorative.
