Storage

Storage

AWWA water storage standards cover the D100 series, which governs the materials used in water storage tanks, including steel, aluminum, concrete, plastic, fiberglass, and geomembrane materials. In addition, multiple types of sacrificial cathodes are discussed to extend the lifetime of these tanks.

AWWA D100-2021

Welded Carbon Steel Tanks for Water Storage

The purpose of this standard is to provide minimum requirements for the design, construction, inspection, and testing of new welded carbon steel tanks for the storage of water at atmospheric pressure.

AWWA D102-2024

AWWA D102-24 Coating Steel Water-Storage Tanks

The purpose of this standard is to provide the minimum requirements for coating steel water-storage tanks, including materials, coating systems, surface preparation, application, and inspection and testing.

AWWA D103-2019

Factory-Coated Bolted Carbon Steel Tanks for Water Storage

The purpose of this standard is to provide minimum requirements for the design, construction, inspection, and testing of new cylindrical, factory-coated, bolted carbon steel tanks for the storage of water. This standard is only applicable to tanks with a base elevation substantially at ground level.

AWWA D104-2023

Automatically Controlled, Impressed-Current Cathodic Protection for the Interior Submerged Surfaces of Steel Water Storage Tanks

The purpose of this standard is to provide the minimum requirements for automatically controlled, impressed-current cathodic protection for the interior submerged surfaces of steel water storage tanks, including design, system components, quality of work, and installation.

AWWA D106-2024

Sacrificial Anode Cathodic Protection Systems for the Interior Submerged Surfaces of Steel Water Storage Tanks

The purpose of this standard is to provide the minimum requirements for sacrificial anode cathodic protection systems for the interior submerged surfaces of steel water storage tanks, including design, system components, quality of work, installation, operation, and maintenance.

AWWA D107-2016

Composite Elevated Tanks for Water Storag

This standard describes the design, construction, inspection, and testing of composite elevated tanks that use a welded steel tank for watertight containment and a single pedestal concrete support structure.

AWWA D108-2019

Aluminum Dome Roofs for Water Storage Facilities

This standard establishes minimum criteria for the design, fabrication, and erection of structurally supported aluminum dome roofs. Aluminum dome roofs can be used on any size tank erected in accordance with AWWA standards. When this standard is specified, in the case of conflict between this standard and any other standard, the requirements of this standard shall govern.

AWWA D110-2025

Wire- and Strand-Wound Circular Prestressed Concrete Water Tanks

The intent of this standard is to provide minimum requirements for the design, construction, inspection, and maintenance of wire- and strand-wound circular prestressed-concrete water tanks with the following four types of core walls: • Type I—Cast-in-place concrete with vertical prestressed reinforcement • Type II—Shotcrete with a steel diaphragm • Type III—Precast concrete with a steel diaphragm • Type IV—Cast-in-place concrete with a steel diaphragm

AWWA D115-2024

Tendon-Prestressed Concrete Water Tanks

This standard describes current and recommended practice for the design, construction, and field observations of concrete tanks using internal tendons for prestressing. This standard applies to containment structures for use with potable water, raw water, or wastewater.

AWWA D120-19 (R2025)

Thermosetting Fiberglass-Reinforced Plastic Tanks

The purpose of this standard is to provide purchasers, manufacturers, and suppliers with the minimum requirements for thermosetting FRP tanks, including material and design.

AWWA D121-2024

Bolted Aboveground Thermosetting Fiberglass-Reinforced Plastic Panel-Type Tanks for Water Storage

The purpose of this standard is to provide minimum requirements for the design, manufacture, construction, and inspection of bolted aboveground thermosetting FRP panel-type (BATFRPP) tanks for the storage of water.

AWWA D130-2011 (R2019)

Geomembrane Materials for Potable Water Applications

This standard pertains to geomembrane materials supplied in sheet form for lining, covering, or lining and covering potable water reservoirs. The successful application of this standard is dependent on an appropriate site evaluation, design, material selection, construction, as well as operations and maintenance. This standard includes requirements for material properties, fabrication, and installation.
