Storage Tank Construction Process:
Project Initiation
- Identifying client requirements: capacity, water type, installation location, and the standards to be met.
- Conducting initial site surveys and project condition evaluations.
- Establishing project frameworks and timelines from the outset.
Engineering Design & Calculation
- Collecting comprehensive technical and environmental data.
- Creating technical designs in accordance with API 650, AWWA, or local regulations.
- Conducting dimension calculations, plate thickness analysis, and structural assessments (water load, wind, earthquake).
- Preparing working drawings (shop and fabrication drawings) for fabrication and construction.
- Obtaining design approvals from clients or supervising consultants.
Procurement
- Vendor selection based on quality, material certification, lead time, and cost.
- Procuring primary materials (steel plate, stainless steel, fiberglass, etc.), accessories (nozzle, manhole, instrumentation, etc.), and fabrication/welding equipment.
- Receipt and inspection of materials at the workshop or project site.
Fabrication and Construction
- Fabrication:
- Cutting and shaping steel plates (cutting, rolling)
- Welding tank components by certified professionals, adhering to QA/QC procedures
- Assembly in the workshop or on-site, following established methods and welding sequences.
- Field Assembly/Erection:
- Lifting, aligning, and welding tank components at the project site.
- Installation of accessories (nozzles, instrumentation, ladders, railings, etc.).
- Testing & Quality Control:
- Visual inspections and Non-Destructive Testing (NDT) of welding joints.
- Hydrostatic testing (leak and strength test using high-pressure water).
- Inspection and verification of dimensions, thickness, and anti-corrosion systems (coating, cathodic protection).
Commissioning & Documentation
- Commissioning: Trial operation of all systems (filling/emptying, instruments, safety systems).
- Documentation: Preparation of as-built drawings, Manufacture Data Report (MDR), operation and maintenance manuals, and tank test certificates.
- Training: Operational training for owner’s staff.
Handover & Final Acceptance
Formal handover of the storage tank to the project owner along with all legal documentation, after-sales warranty, and support services.
Competitive Advantages
- Certified materials All primary materials used—such as steel plates, structural supports, and complementary components like valves—are sourced from verified vendors and always accompanied by official material test certificates. This guarantees complete traceability and full compliance with applicable standards such as API, ASME, SNI, and AWWA including requirements set forth by API 650 or ASME Section VIII.
- Advanced fabrication technology and facilities The workshop is equipped with machinery for cutting, forming, and welding, and further supported by digital systems for design and project management. Quality Assurance/Quality Control (QA/QC) protocols are implemented to ensure that every tank produced meets safety and operational standards. The use of non-destructive testing (NDT), hydrotesting, and modern inspection tools—including drone documentation for hard-to-reach areas—further guarantees product integrity and enhances overall safety.
- Compliance with international safety standards (API, ASME, SNI)
API (American Petroleum Institute): API 650 governs the design, fabrication, installation, and inspection of welded steel storage tanks for petroleum and other liquids. This standard is globally recognized for above-ground tanks, encompassing requirements for materials, design methodology, corrosion protection, and testing. For periodic maintenance and repairs, API 653 is also referenced.
ASME (American Society of Mechanical Engineers): ASME Section VIII establishes the design and construction codes for pressure vessels, which also includes spherical and high-pressure tanks. Adherence to this standard ensures safety for both normal and extreme operating conditions.
SNI (Indonesian National Standard): In Indonesia, SNI 03-1746-1989 regulates the planning of above-ground oil storage tanks, while SNI 13-3501-2002 sets forth requirements for fuel storage facility construction, including fire safety, environmental, and civil aspects. These SNI standards align with API and ASME to form the legal and technical foundation for industrial tank fabrication in Indonesia.
AWWA D100 is a standard issued by the American Water Works Association (AWWA) governing the design, construction, and testing of welded steel tanks for water storage.

PT. Tri Daya Maxima is ready to serve Water Storage Tank fabrication services of various sizes and capacities according to client needs. The water tank itself functions as a container for storing water. Water tanks used to provide water storage are used in many applications, for example storage for drinking water, irrigated agriculture, fire fighting, both for crops and livestock, chemical manufacturing, food preparation and many other uses. Water tank parameters include the general design of the tank and the choice of construction materials. Various materials are used to make the water tank: plastic (polyethylene, polypropylene), fiberglass, concrete, stone, steel (welded or bolted, carbon, or stainless).
