AWWA D103&#;97standard , the Advancing Quality and Durability with Epoxy-Coated Bolted Tanks

In the realm of water storage solutions, quality, and durability are of paramount importance. The American Water Works Association (AWWA) has long been at the forefront of setting standards to ensure the reliability and longevity of water infrastructure. Among the many standards established by AWWA, AWWA D103&#;97 is a key reference for epoxy-coated bolted steel tanks.

AWWA D103&#;97, also known as the Standard for Factory-Coated Bolted Steel Tanks for Water Storage, is a comprehensive guideline developed by AWWA to regulate the design, construction, and performance of bolted steel tanks that store potable water. The standard encompasses various aspects of tank manufacturing, including materials, coatings, structural design, and field assembly. AWWA D103&#;97 serves as a benchmark for ensuring the quality and safety of water storage tanks across North America.

Epoxy Coating: The Protective Shield

At the heart of AWWA D103&#;97 lies the requirement for epoxy coating on the interior and exterior surfaces of bolted steel tanks. Epoxy coatings are applied in a controlled factory environment and offer numerous benefits:

Corrosion Resistance: Epoxy coatings form a robust barrier that protects the steel substrate from corrosion. This is especially crucial for potable water storage tanks, where corrosion can contaminate the water supply.

Chemical Resistance: Epoxy-coated tanks are capable of withstanding exposure to a wide range of chemicals and contaminants without compromising the integrity of the tank or the water quality.

Durability: The epoxy coating enhances the tank&#;s overall durability, ensuring a long service life with minimal maintenance requirements.

Adherence to Quality Standards: AWWA D103&#;97 specifies the thickness, application process, and quality control measures for epoxy coatings, ensuring that they meet stringent standards for safety and reliability.

Key Features of Epoxy-Coated Bolted Tanks Under AWWA D103&#;97

Factory Application: AWWA D103&#;97 mandates that epoxy coatings be applied at the factory under controlled conditions. This factory application ensures uniform and high-quality coatings, eliminating variability that can occur with field-applied coatings.

Interior and Exterior Coating: Both the interior and exterior surfaces of bolted tanks must be coated with epoxy to provide comprehensive protection against corrosion and ensure the quality of stored water.

Coating Thickness: The standard specifies minimum coating thickness requirements to guarantee effective protection and longevity.

Quality Control: Rigorous quality control measures are implemented during the coating application process to verify that coatings adhere to the specified standards.

Applications and Benefits

Epoxy-coated bolted tanks built in accordance with AWWA D103&#;97 find applications in various sectors:

Municipal Water Supply: These tanks are a cornerstone of municipal water systems, storing and safeguarding potable water for communities.

Industrial Use: Industries rely on epoxy-coated bolted tanks to store process water, chemicals, and industrial liquids, ensuring a secure and contamination-free supply.

Agriculture: Farmers use these tanks to store water for irrigation, livestock, and other agricultural needs.

Fire Protection: Epoxy-coated bolted tanks serve as vital components of fire protection systems, ensuring a reliable source of water in emergencies.

Emergency Response: In disaster-prone areas, these tanks can provide a reserve of clean water for disaster relief efforts.
