Selecting the right tank for irrigation, water storage, or other liquid storage applications is an important decision that impacts efficiency, longevity and functionality.

Whether you’re storing potable water, effluent, or other industrial liquids, taking the time to understand your requirements ensures you’ll make the best choice. Here’s an in-depth guide to help you navigate the process.

1.  Understand the application

The first step in selecting a tank is understanding its intended purpose. Is it for irrigation, potable water storage, or something else entirely? Knowing the big picture will guide your choices regarding size, design and materials. For instance, potable water typically requires a roofed tank to prevent contamination, whereas irrigation water might allow for an open-top design – though a roofed option is often better to minimise algae growth and debris accumulation.

2.  Consider what the tank will hold

What your tank will store significantly affects its design and features:

• If the tank will hold potable water, a roof is essential. This prevents algae growth, keeps birds from flocking on the water’s surface, and reduces the entry of debris and insects.
• For irrigation water, either an open or roofed tank may suffice. However, roofed tanks are generally preferable as they prevent algae buildup that can clog pumps, especially if the water is being used for crops like berries that go directly to market.
• For effluent storage, an open-top tank may work, but you’ll need to consider the odour, type, stirring requirements and concentration of the effluent, as well as the proximity to neighbours.

3.  Determine the appropriate size

Tank size is a crucial consideration. Start by assessing how much volume you need during peak usage times. Consider your worst-case scenario: how quickly can your water supply be replenished through bore water or rain catchment? It’s also wise to build in a buffer for unexpected issues, such as pump breakdowns or periods of drought or no rainfall.

4.  Evaluate the location

Where you place your tank will influence its longevity and effectiveness. Look at the surrounding environment. Are there trees that could drop branches or debris onto the tank? Will birds be attracted to an open-top tank and potentially soil the water? Accessibility is another key factor – ensure there’s enough space for installation, maintenance and connections to the end-use. Additionally, if you can locate the tank in a position that allows for gravity-fed distribution, you’ll save on energy costs.

5.  Plan for the future

When choosing a tank, think long-term. What will your needs look like in 5, 10, or even 25 years? If you plan to expand your household or acquire more land for irrigation, your water demands may increase. Tanks like KlipTanks are designed to last for 25 years, so consider whether the tank you choose today will meet your future needs. Also, check if the tank can be relocated should your setup change.

6.  Adhere to regulations

Compliance with local and national regulations is non-negotiable. Research any laws governing tank placement, the type of contents it can hold as well as safety standards. This step ensures you avoid fines or the need for costly modifications later.

7.  Assess space and shape requirements

The space available for your tank will determine its size and shape. Most tanks are round, but square or rectangular options exist for tighter spaces. If ground space is limited, a taller tank might reduce the footprint, but you’ll need to verify that height regulations allow it. Ensure there’s adequate room around the tank for installation and maintenance and prepare the ground appropriately to support the tank’s weight.

8.  Account for environmental conditions

Environmental factors can have a significant impact on your tank’s performance and lifespan. For example, tanks in coastal areas should be corrosion-resistant due to salt exposure. High-UV regions require materials that can withstand prolonged sun exposure. If you’re in an area with heavy snowfall, the tank must have adequate snow-loading capacity. Additionally, consider whether the tank can withstand extreme weather like floods and high winds.

9.  Review warranty and service options

Before purchasing, check the tank’s warranty. Understand what is covered, for how long, and whether after sales service, support and parts are available if needed. Some tanks allow for easy self-servicing of parts, while others might require professional maintenance.

10.  Understand maintenance requirements

Every tank requires maintenance, so it’s important to know what’s involved. Determine how much of the upkeep you can handle yourself and whether a service contract is available for peace of mind. Regular maintenance can extend your tank’s lifespan and ensure optimal performance.

11.  Calculate the costs

Budgeting is a key part of tank selection. Consider the following costs:

• The price of the tank itself
• Installation costs and ground preparation
• Additional expenses for pumps, fittings and other necessary components

It’s also important to think about the tank’s projected lifespan and factor in maintenance costs to get a complete picture of the overall investment.

12.  Select the right materials

The materials used in tank construction should align with your needs and environment. For example, plastic or steel tanks each have unique benefits. Consider whether ground contact, salt spray, or other environmental factors will affect the tank’s durability. Additionally, check the quality of components and materials used right down to quality of screws and bolts.

13.  Sustainability

Sustainability is an important consideration for many buyers. Look for tanks made from recycled materials or those that can be recycled at the end of their life. Consider whether a concrete base is necessary, as this can significantly increase the tank’s carbon footprint.

14.  Decide between flat-packed or pre-assembled tanks

The choice between flat-packed and pre-assembled tanks often depends on logistical factors. Flat-packed tanks are easier to transport and manoeuvre into tight spaces. Pre-assembled tanks, however, may require cranes or Hiabs for installation, which could add to the cost and complexity. Evaluate which option best suits your site and budget.

By carefully considering these factors, you can choose the ideal tank to meet your needs today and in the future. From effluent and irrigation through to potable water storage, the right tank ensures efficiency, reliability, and peace of mind for years to come.
