Water security is a critical concern for South Africa, a country facing significant water stress. According to the South African Weather Bureau, we are one of the 30 driest nations globally, South Africa receives an average annual rainfall of less than 500 mm—about 40% less than the world average.

Ensuring long-term water security is a critical challenge. This article will explore innovative strategies around bladder reservoirs from Damsak®. This versatile solution can revolutionise water management, sustainable water security, and resilience for manufacturing, engineering, farming and more.

Understanding Bladder Reservoirs

Bladder reservoirs provide flexible, efficient storage options, making them valuable tools for ensuring long-term water security. Damsak® bladder reservoirs are manufactured from polyester-reinforced potable grade polyvinyl-chloride (PVC). This material combines the strength and flexibility of polyester fibres, making it exceptionally strong, with durability and chemical resistance to many acids, salts, corrosives, bases, fats, and alcohols. It is safe for storing water for human consumption.

Benefits of Bladder Reservoirs

Unlike traditional concrete or earthen reservoirs with fixed shapes and sizes, bladder reservoirs can conform to the available space and terrain. They are easy to install.

Evaporation from surface water bodies is a significant concern, especially in arid and semi-arid regions. Bladder reservoirs address this issue by minimising direct water exposure to the atmosphere. The solid material of the bladder prevents water loss through evaporation, resulting in higher water retention efficiency. They accommodate seasonal variations and unexpected changes in demand. Compared to open concrete reservoirs, bladder reservoirs minimise surface area, reducing water loss due to evaporation.

Bladder reservoirs expand or contract based on the water volume, ensuring a reliable supply this conservation measure is crucial for long-term water security.

They are also lightweight and easy to transport, making them ideal for emergencies. Their cost-effectiveness allows for widespread adoption and scalability. Need more storage?

Integrating Bladder Reservoirs into Water Security Strategies

Despite recent rains, the country remains classified as “water short” and is moving toward a “water-stressed”, country-wide.

Bladder reservoirs offer a flexible and efficient solution for water storage. From preserving dam capacity, and acting as an emergency water supply during droughts, bladder reservoirs serve as backup water sources, ensuring continuity even when other systems are strained.

Additional Water Security Approaches Using Bladder Reservoirs

Bladder reservoirs can work alongside or replace traditional dams, for rainwater harvesting, and desalination plants to enhance existing water storage capacity. As some large dams lose storage due to sand buildup, bladder reservoirs provide an additional buffer, extending the useful life of existing dams.

Rainwater Harvesting: Bladder reservoirs can store collected rainwater from rooftops, parking lots, and open spaces in urban areas. This harvested water supplements the municipal supply and reduces stress on existing systems. They also capture excess water, preventing flooding and allowing controlled release.

Conclusion

Bladder reservoirs offer a dynamic solution for long-term water security. These reservoirs adapt to varying terrains, minimise evaporation losses, and expand or contract according to the volume of stored water. Their lightweight design, cost-effectiveness, and compatibility with existing systems make them essential tools for sustainable water management. By integrating bladder reservoirs into water security strategies, industries and companies can enhance storage capacity, extend the useful life of existing dams, and ensure continuity during emergencies.
