Everything You Need to Know About Water Tanks & Water Storage Solutions

As the need for water conservation grows for households, farms, and businesses across Australia and beyond, the role of water tanks in managing water effectively has become increasingly important. Whether you are collecting rainwater for your garden, supplying water for livestock, or trying to reduce your dependence on city water, choosing the right water tank is a smart choice.

In this article, we will explore the benefits of water tanks, the different types available, and how to pick the best option for your needs. If you are new to water storage or are thinking about upgrading your current system, this guide will provide the information you need.

Why Invest in a Water Tank?  

Before discussing the types and features, it’s essential to understand why water tanks are a valuable investment:

1. Water Security  

During droughts, restrictions, or supply issues, having a stored supply of clean water is crucial for daily activities, especially in rural or off-grid areas.

2. Cost Savings  

Using rainwater from your tank can significantly lower your reliance on mains water and reduce your utility costs over time.

3. Environmental Impact  

Collecting rainwater and reusing greywater eases the pressure on municipal systems and promotes sustainable water use, especially in drought-prone regions.

4. Versatility  

Water tanks can serve multiple purposes:

• Drinking water (when properly filtered)
• Irrigation and garden watering
• Firefighting reserves
• Water supply for livestock
• Industrial uses

Tanks can also store bore water or recycled greywater, expanding options for areas at risk of drought. In properties with multiple dwellings or apartment complexes, communal water tanks are becoming popular as they help cut shared utility costs and boost sustainability ratings.

In commercial settings, businesses can use water tanks for cleaning, cooling systems, and processing water, which can enhance efficiency and meet environmental standards.

Practical Uses and Long-Term Benefits of Water Tanks

Beyond saving money and conserving resources, water tanks provide everyday benefits. For gardeners, rainwater supports healthier plant growth because it lacks chlorine and added chemicals. Car owners appreciate streak-free washing, and households using tank water for laundry enjoy softer water, leading to reduced detergent use and less wear on appliances.

In rural environments, water tanks can be connected to drip irrigation systems, livestock troughs, and firefighting setups, which are vital during bushfire season. Some councils even require a dedicated water supply for fire emergencies in high-risk areas.

On the commercial side, businesses in food processing, landscaping, and construction leverage tanks to cut costs. Collecting rainwater for machinery washdowns, mixing concrete, or cooling systems promotes sustainability and lessens reliance on costly main supplies.

Additionally, a reliable water storage system can add value to a property. Potential buyers often appreciate self-sufficiency, eco-friendly setups, and lower utility bills, making water tanks a solid long-term investment.

Choosing the Right Tank Size 

Water tanks come in sizes from 300 liters to over 300,000 liters. When estimating the size you need, consider:

1. Roof Area: A larger catchment allows for more rain collection
2. Rainfall: Your area’s climate affects water harvesting
3. Water Usage: Include gardens, washing, toilets, and livestock

Businesses should also consider peak demand, water recycling options, and backup needs to ensure consistent supply.

It’s wise to future-proof your choice by allowing for some extra capacity in case demand increases or you expand. Slightly overestimating is usually better than running out during critical times.

Key Features to Look for in a Water Tank 

To make the best choice, examine qualities related to durability and longevity, such as:

• UV Stabilisation: Prevents sun damage to poly tanks
• Food-Grade Materials: Safe for drinking water
• Overflow & Leaf Guards: Keeps water clean

Proper Installation:

– Ensure a stable, level base (concrete slab or compacted base)

– Allow for access to plumbing and routine checks

– Use filters and diverters for clean water collection

Maintenance Checklist:

– Clean gutters and strainers regularly

– Inspect for leaks, cracks, or contamination

– Clean inside the tank every 2 to 3 years if used for drinking water

Rainwater Harvesting: How It Works  

A typical rainwater harvesting system includes:
