SMC (Sheet Molding Compound) panel water tanks are modular fiberglass water tanks composed of square or rectangular molded panels. These panels are assembled on-site in different configurations to achieve various tank volumes. Leading brands like GTOFRP™ offer standard and custom sizing options, making them adaptable to nearly all project requirements.
SMC water tanks are typically made from 1-meter-square panels (1000mm × 1000mm). Other common sizes include:
1000mm × 500mm
500mm × 500mm
Tanks can be configured in any combination of length × width × height using these panel dimensions. For example:
| Configuration (L × W × H) | Volume (Approx.) |
|---|---|
| 2m × 2m × 1m | 4,000 liters |
| 3m × 3m × 2m | 18,000 liters |
| 5m × 4m × 2m | 40,000 liters |
| 6m × 5m × 3m | 90,000 liters |
Note: Actual capacity may vary based on internal bracing and overflow margins.
Use the following rough estimates as a baseline:
Residential use: 150–250 liters per person per day
Office buildings: 30–50 liters per person per day
Manufacturing facilities: Varies widely; consult process engineers
Firefighting reserves: 20,000 liters or more depending on local codes
Modular tanks can be designed to fit constrained rooftops, basements, or building shafts. You can expand horizontally or vertically based on layout.
Larger tanks require a concrete base with load-bearing capacity. The site should be level and capable of supporting both the tank and water weight (1 m³ = 1 ton of water).
Ensure enough clearance (typically ≥500mm) around the tank for inspection and cleaning. GTOFRP™ tanks come with optional access hatches and ladders.
| Application Area | Suggested Tank Size | Notes |
|---|---|---|
| Household (4–6 people) | 2m × 2m × 1.5m (6,000 L) | For daily water supply and backup |
| Small hotel or office | 4m × 3m × 2m (24,000 L) | For multiple toilets, kitchens, HVAC |
| School or hospital | 5m × 4m × 2.5m (50,000 L) | Based on average occupancy and usage |
| Factory or industry | ≥6m × 5m × 3m (90,000+ L) | May require multiple tanks |
| Fire water storage | 3m × 3m × 2m (18,000 L) | Complies with many safety regulations |
GTOFRP™ offers flexible customization with the ability to:
Mix panel sizes for optimal fit
Add internal bracing for larger heights
Provide food-grade or industrial-grade resins
Support on-site design planning and dimension calculation
All tanks comply with international standards and can be adapted for high-temperature zones, seismic areas, or specific drainage configurations.
Selecting the right SMC panel water tank size ensures your water system operates efficiently and reliably. By evaluating consumption needs, space constraints, and structural requirements, you can avoid under-sizing or over-investing.
Whether you're building for a small household or a large industrial facility, GTOFRP™ offers a comprehensive range of modular FRP tanks to match every project scale with performance and reliability.
