When it comes to water storage, one size doesn’t fit all. Selecting the right water tank size is a crucial decision that impacts water availability, cost, and overall satisfaction. In this buyer’s guide, we’ll walk you through the process of choosing the perfect water tank size to meet your specific needs. Whether you’re a homeowner, farmer, or business owner, getting the size right ensures a reliable and cost-effective water supply.

Understanding Your Water Needs

To begin, you must have a clear understanding of your water requirements. Consider factors such as daily water usage, seasonal fluctuations, and any unique needs you might have. Whether it’s for household use, agriculture, or industrial purposes, your water demands should drive your choice of tank size.

Before delving into size considerations, it’s essential to choose a reputable supplier. Great Northern Tanks, a well-known brand in the industry, offers a range of high-quality water storage solutions. Their expertise and commitment to customer satisfaction make them a dependable choice for your water tank needs.

Calculating Water Usage

Estimating your water consumption is the foundation of choosing the right tank size. Start by tracking your daily usage, including drinking, bathing, cooking, and other household or business-related activities. Additionally, consider seasonal variations in water needs, such as increased usage for irrigation during the summer months.

Selecting the Tank Size

Once you have a clear picture of your water requirements, it’s time to choose the appropriate tank size. Great Northern Tanks provides options to suit various needs:

Small-Scale Tanks for Residential Use

For homeowners and smaller-scale users, Great Northern Tanks offers compact yet efficient tanks. These are perfect for meeting daily household water needs while minimizing space requirements.

Medium-Scale Tanks for Farms and Small Businesses

Agricultural operations and small businesses benefit from medium-sized tanks. These tanks strike a balance between capacity and space, providing ample water storage without overwhelming your property.

Large-Scale Tanks for Industrial and Commercial Use

Industrial and commercial enterprises often require substantial water reserves. Great Northern Tanks’ large-scale tanks are designed to meet the demands of such operations, ensuring a consistent water supply.

Space and Location Considerations

Beyond size, consider where you’ll place your water tank. Ensure you have enough space for the tank and any necessary infrastructure. The tank’s location can affect efficiency and accessibility.

Material Choices: Colorbond vs. Aluzinc

Great Northern Tanks offers tanks in two materials, each with its unique benefits:

  • Colorbond: Known for its durability and aesthetic appeal, Colorbond tanks are a popular choice for those seeking both functionality and visual appeal.
  • Aluzinc: If corrosion resistance is a priority, Aluzinc tanks are an excellent option, especially in harsh environments.

Budget Considerations

Budget plays a crucial role in selecting a water tank size. Great Northern Tanks offers competitive pricing, and understanding your budget constraints helps narrow down your options.

Installation and Maintenance

Consider the installation process and ongoing maintenance requirements when choosing a tank size. Smaller tanks are often easier to install, while larger tanks may require more complex setups. Additionally, all tanks require regular maintenance to ensure optimal performance and longevity.


In the world of water storage, size matters. Choosing the right water tank size is a decision that shouldn’t be taken lightly.
