South Africa’s growing water scarcity, unpredictable rainfall, and rising infrastructure costs have made one thing clear — sustainable water storage is no longer optional.
From farms to factories, mines to municipalities, having a reliable water supply is the backbone of productivity. Whether you’re collecting rainwater, storing municipal backup, or managing process water, the tank you choose can determine your long-term reliability and operating costs.
That’s where Flexitank Systems comes in — offering a complete range of modular steel tanks, bladder tanks, and lined reservoirs designed for Africa’s toughest environments.
Many companies make the mistake of prioritizing upfront cost over quality. But in reality, the wrong tank can cost you far more in the long run due to:
Leaks and contamination from poor sealing or cheap materials
Rust and corrosion, especially in coastal or high-humidity environments
Difficult installations and high transport costs for rigid tanks
Limited lifespan — leading to premature replacement or constant maintenance
Downtime and water loss, disrupting operations or irrigation
A professionally designed and properly installed tank system not only stores water — it protects your investment.
Best for: Industrial sites, commercial facilities, municipal storage, and fire protection.
Sectional steel tanks (also called pressed steel tanks) are made from modular galvanized steel panels bolted together on-site. This design makes them ideal for high-capacity storage (from 10,000L to over 5 million litres) and easy to transport to remote areas.
Key advantages:
Fast modular installation
Long lifespan (over 25 years with minimal maintenance)
Customizable in size and height
Suitable for ground-level or elevated applications
Compatible with PVC or butyl liners for total water integrity
💧 At Flexitank Systems, our sectional steel tanks are manufactured to SANS, ensuring durability and hygiene compliance for potable water.
Best for: Long-term agricultural and commercial storage.
Circular (or “Pi”) tanks combine the strength of corrugated steel with internal liners that protect water quality. These tanks are perfect for farms, irrigation, and rainwater harvesting systems.
Advantages:
Aesthetic and durable design
UV-resistant, corrosion-protected steel
Simple to assemble
Ideal for large-scale water harvesting
Best for: Temporary projects, agriculture, military, and emergency applications.
Bladder tanks are collapsible, flexible water tanks that can be deployed quickly and moved easily. They’re made from reinforced PVC or TPU fabric — ideal for clients needing short-to-medium-term water or fuel storage.
Benefits include:
Compact when empty — easy to transport and store
Quick setup with no heavy civil works
Cost-effective for remote or temporary use
Available in custom sizes (1,000L to 500,000L+)
🌍 FTS bladder tanks are trusted by construction, aid, and agricultural sectors across Africa for mobile and backup water storage.
Best for: Agricultural irrigation, aquaculture, and stormwater management.
PVC-lined earth dams combine cost-effective excavation with high-grade PVC liners, turning a basic earth basin into a professional, sealed reservoir.
