Standards
AWWA D103 Compliant Modular Water Tanks
Kolleksan can engineer factory-coated, bolted steel water tanks in line with the technical requirements of the AWWA D103 standard. Panel structure, connection components, protective coating, capacity, and on-site installation conditions are evaluated together to produce long-lasting modular water tanks.
For galvanized, coated, and stainless steel tanks, material selection is determined based on potable water, fire water, and industrial water storage needs. Systems developed specifically for the project provide safe installation and sustainable use advantages for high-capacity requirements.
AWWA D103 is an internationally recognized standard covering factory-coated, bolted carbon steel water tanks.
NFPA 22 Compliant Fire Water Tanks
Kolleksan can engineer NFPA 22-compliant fire water tanks that safely store the water reserve required for fire safety systems. Tank capacity, material selection, and site conditions are evaluated according to the project’s technical requirements.
In fire water tank design, the required water capacity, duration of use, connection points, environmental loads, and installation conditions are considered together. Galvanized, coated, or stainless steel modular water tanks manufactured by Kolleksan provide solutions for safely storing the water needed for sprinkler systems, fire hose cabinets, and hydrant lines.
Modular fire water tanks engineered in line with NFPA 22 requirements can be configured for different capacity needs, from industrial facilities to commercial buildings. Production, installation, and technical checks are managed within a single engineering process.
NFPA 22 covers the design, manufacturing, installation, and maintenance requirements for water tanks that supply fire protection systems.
TSEK 304 Criteria Conformity Certificate
Kolleksan holds the TSEK 304 Criteria Conformity Certificate. TSEK is the Criteria Conformity Certificate mark issued by the Turkish Standards Institution (TSE) for products without a Turkish Standard; the certificate shows that a product conforms to the criteria accepted by TSE and allows the use of the TSEK mark.
