Rainwater Harvesting Tanks: Why FRP Storage Tanks Are Best

Australia is a land of diverse climates, with different regions experiencing both periods of drought and abundant rainfall. With increasing water restrictions, fluctuating annual rainfall, and growing environmental concerns, harvesting rainwater has become a crucial step for households, businesses, and rural properties alike.

One of the most efficient solutions for storing harvested rainwater is Fibreglass Reinforced Plastic (FRP) storage tanks. In this blog from CSG Composites’ rainwater tank experts, we’ll explore why FRP water tanks are the best option for rainwater harvesting systems and how they outperform traditional storage methods.

What is an FRP Water Tank?

Before we go any further, let’s explain what an FRP tank is for those who don’t know. Fibre Reinforced Plastic (FRP) water tanks are lightweight, durable storage solutions made from high-quality composite materials. These tanks are designed with high-quality materials to prevent corrosion, reduce maintenance, and maintain uncontaminated water quality over decades of use.

Unlike concrete tanks that are prone to cracking and degradation over time, our Australian manufactured FRP storage tanks maintain their structural integrity in diverse conditions, from urban areas to rural properties. Their non-toxic, bacteria-resistant materials make them ideal for storing rainwater for irrigation, livestock use, crop spraying, or even domestic purposes like toilet flushing and cooling systems.

5 Reasons Why FRP is the Best for Rainwater Harvesting Tanks

1. Corrosion Resistance: FRP tanks are engineered to prevent corrosion, unlike other storage tanks. This makes them ideal for long-term water storage, ensuring the quality of rainwater remains high for various applications, including drinking water after treatment.
2. Longevity and Durability: With a 100-year design life, our FRP rainwater tanks offer unmatched durability. Whether installed as an underground water tank or an above-ground tank, they’re able to resist wear and tear from harsh Australian climates.
3. Lightweight and Easy Installation: FRP tanks are significantly lighter than traditional tanks, reducing transportation and installation costs. Their quicker installation process is particularly advantageous for properties with limited available space or specific project timelines.
4. Bacteria Resistance and Non-Toxic Material: The non-toxic materials used in producing the FRP tanks ensure that the stored water remains safe for use in irrigation and household activities. The tanks also resist bacteria growth, enhancing water quality and safety.
5. Cost-Effective Maintenance: FRP tanks require minimal maintenance compared to traditional tanks, lowering ongoing costs. Their seamless construction prevents leaks and other degrading factors to reduce the need for repairs over their extensive lifespan.

What Can Rainwater Be Used For?

Rainwater harvesting opens up a variety of practical uses for the water collected from roofs and hard surfaces. Here are some common applications for our tanks:

• Irrigation: As we mentioned above, rainwater is an excellent resource for maintaining gardens, crops, and landscaped areas, especially in regions with limited water supply.
• Livestock: On rural properties, collected rainwater can provide a consistent water supply for livestock.
• Domestic/ Residential Uses: Rainwater can be filtered and treated for household activities like washing clothes, cleaning driveways, and flushing toilets.
• Industrial Applications: Rainwater is commonly used in cooling systems and other industrial operations to conserve mains water supply.
• Emergency Supply: With a reliable rainwater harvesting system, properties can maintain a backup water supply during periods of drought or water restrictions.

By utilising rainwater, individuals and businesses can reduce their reliance on mains water, minimise costs, and support Australia’s environmental sustainability efforts.

How Do Rainwater Harvesting Systems Work?

A rainwater harvesting system collects water runoff from roof surfaces or hard standings, diverting it into storage tanks through a series of gutters, downpipes, and filters. Here’s an overview of the process:

1. Collection: Rainwater is collected from surfaces such as roofs, driveways, or other impermeable areas.
2. Filtration: Filters remove leaves, debris, and sediment, ensuring the water is clean before entering the tank.
3. Storage: The filtered water is stored in rainwater harvesting tanks, which can be installed either above ground or underground.
4. Distribution: Depending on the system’s design, the stored water is then distributed for irrigation, household use, or industrial applications.

By installing a well-designed rainwater harvesting system, property owners can maximise water usage efficiency while reducing reliance on mains water supply.

Can Rainwater Tanks Be Underground?

Yes, FRP rainwater harvesting tanks can be installed underground. In fact, underground rainwater tanks are an excellent solution for properties with limited surface space or design and aesthetic considerations.

Benefits of Underground Water Tanks:

• Space Efficiency: Underground water tanks leave above-ground areas free for landscaping, driveways, or additional infrastructure.
• Temperature Stability: Storing water below ground can help maintain a consistent temperature, reducing algae growth and preserving water quality.
• Aesthetics: By keeping storage tanks hidden, properties maintain their visual appeal while benefiting from a reliable water supply.

Our Rainwater Harvesting Tanks are particularly manufactured for underground installation due to their lightweight construction and resistance to ground pressure. Their advanced design ensures that they’ll perform effectively without the cracking or leakage issues often associated with other tanks.

What is the Life of an FRP Water Tank?

CSG Composites’ FRP water tanks boast an impressive design life of up to 50 years, making them a superior choice for long-term water storage. This longevity is attributed to their corrosion-resistant materials and robust construction, which withstand environmental and structural stressors.

Unlike concrete tanks, which may require repairs or replacement, our FRP tanks maintain their integrity with minimal maintenance. Their extended lifespan provides property owners with peace of mind, knowing their rainwater harvesting systems will remain reliable for generations to come.
