Installation Guide

Tank Installation Guide

Professional installation procedures for vertical storage tanks. From site preparation through commissioning, follow these guidelines for a safe and successful installation.

Pre-Installation Requirements

Essential preparations before tank delivery to ensure a smooth installation process.

📐

Site Preparation

Level, compacted surface capable of supporting full tank weight. Concrete pad recommended for tanks over 50,000 gallons. Ensure proper drainage and consider future access needs.

🚚

Access Requirements

Clear path for delivery trucks (minimum 12' wide, 14' height clearance). Crane access if required (most tanks use our lifting jack method which needs no crane). Level staging area near installation site.

🔌

Utilities & Services

Electrical service for heating systems (if applicable). Water supply connection point identified. Piping routes planned. Verify local permit requirements before starting work.

Installation Process

1

Foundation Preparation

The foundation must be level within 1/8" per 10 feet and capable of supporting the full weight of the tank plus water. Foundation type depends on tank size and soil conditions.

  • Compact sub-grade to 95% Standard Proctor
  • Install concrete ring wall or full pad per engineering specs
  • Verify level and dimensions before tank delivery
  • Allow concrete to cure minimum 7 days (28 days preferred)

Foundation specifications vary by tank size and soil conditions. Contact our engineering team for your specific requirements.

2

Tank Delivery & Unloading

Tank panels, hardware, and accessories are delivered on flatbed trucks. Inspect all components upon arrival and report any damage immediately.

  • Verify shipment against packing list
  • Inspect panels for damage during transit
  • Stage components near installation site
  • Protect panels from ground contact and weather
3

Tank Positioning & Assembly

Using our proprietary lifting jack erection method, the tank is assembled from the top down. This eliminates the need for cranes and scaffolding, improving safety and reducing installation time.

  • Begin with roof assembly at ground level
  • Lift roof and add wall panels from bottom
  • Bolt panels with specified torque values
  • Apply sealant to all joints per specifications
  • Maintain minimum clearance: 3 feet from structures, 6 feet from property lines
4

Anchoring & Securing

Proper anchoring is critical for wind and seismic loads. Anchor bolt specifications depend on tank size, wind zone, and seismic requirements.

  • Install anchor bolts per engineering drawings
  • Torque all anchors to specified values
  • Verify plumb and alignment
  • Apply corrosion protection to anchor hardware
5

Piping Connections

Connect inlet, outlet, overflow, drain, and vent piping per the engineered drawings. All connections must be properly supported and allow for thermal expansion.

  • Install inlet and outlet connections
  • Connect overflow piping with proper discharge
  • Install drain valve at tank bottom
  • Verify atmospheric vent is properly installed
  • Install fire department connections (fire protection tanks)
6

Testing & Commissioning

Fill the tank with water and inspect all joints, connections, and accessories. Document the commissioning process for compliance records.

  • Perform hydrostatic leak test
  • Inspect all bolted joints for leaks
  • Test all valves and accessories
  • Verify level indicators and alarms
  • Test heating system operation (if applicable)
  • Complete commissioning documentation
