Underground Water Tanks

Description

Underground galvanized water tanks are engineered storage solutions designed for clients who require long-term, secure, and space-efficient water storage below the surface. These tanks are built using high-grade galvanized steel sheets that are corrosion-resistant, pressure-tolerant, and structurally reinforced to withstand underground conditions such as soil pressure, fluctuating moisture levels, and environmental shifts.

They are ideal for residential compounds, commercial properties, industrial facilities, farms, hotels, hospitals, schools, and municipal water systems where discreet and protected water storage is required without occupying surface land.

1. Key Features of Underground Galvanized Water Tanks

1.1 Heavy-Duty Galvanized Steel Construction

These tanks are fabricated using hot-dip galvanized steel sheets that offer excellent resistance to:

• Moisture and groundwater

• Subsoil corrosion

• Chemical exposure

• Bacterial contamination

The galvanizing process forms a zinc coating that protects the steel from environmental degradation, ensuring long service life.

1.2 Underground Installation Design

The tanks are engineered for subsurface installation and reinforced to handle:

• Vertical soil load

• Lateral soil pressure

• Ground movement

• Buoyancy resistance (where groundwater levels fluctuate)

Structural ribs and stiffeners are integrated to prevent deformation.

1.3 Leak-Proof, Sealed Construction

All seams are fully welded or bolted with gasket reinforcement to ensure zero leakage. Internal sealants (food-grade) can be applied for added water purity.

1.4 Customizable Capacities

Depending on client needs, underground galvanized tanks can be fabricated in a wide range:

• 5,000 litres

• 10,000 litres

• 20,000 litres

• 30,000 litres

• 50,000 litres

• 100,000 litres and above

Shape options include cylindrical, rectangular, and segmented modular tanks.

1.5 Space-Efficient

Since installation is underground, you preserve:

• Parking space

• Walkways

• Gardens

• Usable yard or compound area

Perfect for urban locations with limited land.

3. Advantages of Underground Galvanized Water Tanks

3.1 Long-Term Durability

The zinc coating provides decades of rust protection, making the tank suitable for underground exposure.

3.2 Hidden and Secure

Because they remain buried, the tanks are protected from:

• Vandalism

• Harsh weather

• Accidental damage

• UV degradation

3.3 Excellent for Limited Space

Surface area remains functional for daily activities such as parking or landscaping.

3.4 Easy to Install and Maintain

The tanks are delivered ready for installation, requiring:

• Excavation

• Base preparation (compacted sand or concrete)

• Tank placement

• Backfilling

Maintenance is minimal due to corrosion protection.

3.5 Hygienic Water Storage

Optional internal linings ensure safe storage for:

• Domestic water

• Drinking water

• Industrial process water

• Fire suppression systems

4. Applications

Underground galvanized steel tanks are used in:

• Residential water supply

• Commercial and industrial water storage

• Borehole storage systems

• Rainwater harvesting

• Firefighting reserves

• Irrigation systems

• Municipal facilities

• Farm settlements

• Hotels and real estate developments
