Rainwater Tanks vs. Cartage Tanks: Understanding Their Unique Purposes

When it comes to water storage solutions, not all tanks serve the same function. Rainwater tanks and cartage tanks are two of the most prevalent kinds that you may come across. While both are designed to store water, their purposes, design features, and ideal applications are quite different. Knowing the distinctions can help you choose the right option based on your needs.

What Are Rainwater Tanks?

Rainwater tanks are installed at homes, farms, or commercial sites to collect and store rainwater, usually from roof catchment systems. This stored water can be used for a variety of purposes—gardening, washing, flushing toilets, and even for drinking if properly filtered. They come in various sizes and materials like polyethylene, steel, or concrete, depending on storage requirements and environmental conditions.

Key features of rainwater tanks:

• Fixed installation: Typically set up at a permanent location.
  
• Connection to guttering systems: Collects water from roof runoff.
  
• Available in large capacities: Ideal for long-term water storage.
  
• Can be used in water-saving systems: Especially valuable in areas with water restrictions.
  

What Are Cartage Tanks?

Cartage tanks, on the other hand, are designed for water transportation rather than long-term storage. These are often used on the back of utes, trailers, or trucks to carry water to remote locations, construction sites, or farms. They're built for mobility and are usually made from durable polyethylene to withstand movement and rough handling.

Key features of cartage tanks:

• Portable: Designed for easy transport.
  
• Compact and rugged: Built to handle tough conditions.
  
• Suitable for multiple liquids: Some models are made to carry not just water, but also chemicals or diesel.
  
• Used for temporary supply: Perfect when you need water on-site but don’t have fixed access.
  

If your goal is to harvest and store rainwater at your home or property, a rainwater tank is the way to go. It’s a long-term investment that helps reduce your dependence on mains water and can lead to significant savings over time.

However, if you’re involved in farming, construction, or any activity that requires moving water from one place to another, a cartage tank offers the flexibility and durability needed for the job.
