At Green Shredder, we believe in working with nature, not against it. A garden thrives when it has what it needs: rich soil, plenty of sunlight, and a steady supply of water. But water can be unpredictable. Some seasons bring too much, others not enough. A water storage tank helps take control of that unpredictability, making sure your plants always have what they need without relying entirely on mains supply.
Collecting rainwater isn’t a new idea. For generations, gardeners have used barrels and underground wells to store water for dry spells. Today, modern water storage tanks offer a more efficient way to do the same. They help reduce reliance on treated tap water, cut utility bills, and make the most of natural resources. Whether you’re watering flower beds, filling a pond, or keeping a vegetable patch healthy, storing rainwater is one of the simplest ways to practice sustainable gardening.
Different gardens need different amounts of water. A small space with a few raised beds might only need a compact 75-Litre Water Tank, while a larger garden with fruit trees and multiple flower beds might benefit from a 500-Litre Water Tank. For those managing larger-scale irrigation, something like the 1250L Water Tank can store enough water to keep plants hydrated through long dry spells.
Installing a water storage tank is easier than most people think. The first step is choosing a location. A flat, stable surface close to a gutter downpipe is ideal. This allows rainwater to flow directly from the roof into the tank. Most tanks come with an inlet for this purpose, and adding a filter helps keep out leaves and debris. Once in place, a tap or hose connection makes it easy to access the water when needed. Regular maintenance is simple—check for debris, clean filters occasionally, and make sure there are no leaks.
The benefits go beyond the garden. By using stored rainwater, you reduce the demand on local water supplies. Tap water is treated with chemicals like chlorine, which plants don’t need. Rainwater, on the other hand, is naturally soft and free from additives. This makes it better for delicate flowers, fruiting plants, and even soil health. It also helps prevent runoff, which can wash away topsoil and nutrients during heavy rains.
For those who want a compact solution, the 85-Litre Water Tank is a great choice. It fits neatly into smaller spaces, perfect for patios or balconies. If space allows, stepping up to a 250-Litre Upright Tank provides more capacity without taking up much room. Those managing multiple garden zones or larger properties might prefer the 800-Litre Water Tank, ensuring a steady supply for watering, cleaning tools, or even filling livestock troughs.
Sustainable gardening isn’t just about water storage – it’s about using resources wisely. Pairing a water tank with mulch helps keep moisture in the soil, reducing how often plants need to be watered. Choosing native plants that thrive in local conditions cuts down on water use. Collecting kitchen scraps for compost creates nutrient-rich soil that holds moisture better. Each small step makes a difference, and together they create a garden that works in harmony with the environment.
Many people ask if stored rainwater is safe for edible plants. The answer is yes, with a little care. If collecting from a roof, it’s best to use a filter to remove any debris. Letting the first flush of rainwater run off before collecting helps, too. For those who want extra reassurance, boiling the water before use or using it at the base of plants rather than on leaves is a simple precaution.
Another common question is how long water can be stored. As long as the tank is covered to prevent algae growth and kept clean, rainwater can be stored for months without issue. A well-maintained tank provides a reliable backup during dry periods, keeping a garden healthy without the worry of restrictions or high water bills.
At Green Shredder, we’ve selected a range of home water tanks to suit different needs. Whether it’s a compact 125-Litre Water Tank for a small garden or a high-capacity 350-Litre Water Tank for more demanding use, every model is built for durability and ease of use. Investing in one means taking a step toward smarter, more sustainable gardening.
Gardening is about patience, care, and working with nature. A water storage tank is one of the best ways to do that. It saves money, conserves resources, and keeps plants thriving even when the weather doesn’t cooperate. Whether you’re growing vegetables, tending flowers, or simply keeping your outdoor space green, stored rainwater is a reliable, eco-friendly solution.
