How to Select Best 100 Litre Water Butt Set for Your Garden

100 Litre Water Butt Set

Water conservation is a significant concern for environmentally conscious gardeners. One of the most effective ways to collect and store rainwater for garden use is by using a water butt. Specifically, a 100 litre water butt set is an excellent choice for those with medium-sized gardens, providing an ample supply of water without taking up too much space. In this comprehensive guide, we’ll explore the essential factors to consider when selecting the best 100 litre water butt set for your garden.

Why Choose a 100 Litre Water Butt Set?

A 100 litre water butt set strikes a balance between capacity and convenience. It’s large enough to collect a substantial amount of rainwater, yet compact enough to fit comfortably in most garden spaces. This capacity is ideal for watering plants, filling watering cans, or even washing garden tools.

Key Considerations When Selecting a 100 Litre Water Butt Set

1. Material Quality

The material of your water butt is crucial for durability and longevity. Common materials include:

  • Plastic: High-density polyethylene (HDPE) is a popular choice for its durability and resistance to UV rays and impact damage. It’s lightweight and easy to move.
  • Wood: Wooden water butts have a classic look and can blend seamlessly into garden aesthetics. However, they require more maintenance to prevent rot and ensure longevity.
  • Metal: Less common for water butts but very durable. Metals like galvanized steel are robust and long-lasting, though they can be prone to rust if not properly treated.

2. Design and Aesthetics

Water butts come in various shapes and designs to suit different garden styles:

  • Traditional Barrels: These have a classic look and often come with wooden finishes.
  • Slimline Designs: Ideal for smaller gardens or narrow spaces, these water butts take up less ground space.
  • Modern Styles: Some water butts have sleek, contemporary designs that can add an aesthetic touch to your garden.

Choose a design that complements your garden while also being practical in terms of placement and access.

3. Lid and Cover

A secure lid is essential to keep debris, insects, and small animals out of your water butt. Some lids are designed with child safety in mind, ensuring they can be locked to prevent accidents. Additionally, a covered water butt helps prevent algae growth by limiting light exposure.

4. Ease of Installation

Consider how easy it is to install the water butt. Most 100 litre water butt sets come with the necessary fittings and instructions, but it’s worth checking the following:

  • Gutter Diverter Kit: This is used to channel water from your downpipe into the water butt. Ensure it fits your existing guttering system.
  • Stand: Some water butts come with a stand to elevate them, making it easier to fill watering cans from the tap.

5. Maintenance Requirements

Maintaining your water butt ensures it remains functional and safe for use. Look for features that make maintenance easier:

  • Drainage Tap: A tap at the bottom makes it simple to drain the water butt completely for cleaning.
  • Removable Lid: A lid that can be easily removed will facilitate cleaning and checking the water quality.
  • Filter Systems: Some water butts come with built-in filters to prevent debris from entering and contaminating the water.

6. Price and Value

Price is always a consideration, but it should be balanced with the quality and features of the water butt. A more expensive water butt with superior materials and useful features might be a better long-term investment than a cheaper, lower-quality option.

7. Brand Reputation

Choosing a reputable brand can ensure you get a quality product with good customer support. Look for brands that offer warranties and have positive reviews from other users.

Additional Features to Look When Selecting 100 Litre Water Butt Set

While the primary function of a water butt is to collect and store rainwater, some additional features can enhance its usability and efficiency:

  • Integrated Overflow System: This prevents overflow during heavy rain, redirecting excess water away from the foundation of your house.
  • Linking Kits: These allow you to connect multiple water butts together, increasing your overall water storage capacity.
  • Child Safety Locks: Ensuring the water butt is safe in gardens where children play is crucial.

Step-by-Step Guide to Installing a 100 Litre Water Butt Set

Step 1: Choose the Location

Select a location that is close to a downpipe and convenient for accessing the water. Ensure the ground is level and stable.

Step 2: Install the Stand

If your water butt comes with a stand, assemble and position it according to the instructions. The stand elevates the butt, making it easier to fill watering cans.

Step 3: Attach the Gutter Diverter Kit

Cut a section of your downpipe where you want to install the diverter. Attach the diverter according to the manufacturer’s instructions, ensuring it’s secure and aligned properly to channel water into the water butt.

Step 4: Connect the Water Butt

Attach the hose from the diverter to the inlet on the water butt. Ensure all connections are tight and sealed to prevent leaks.

Step 5: Secure the Lid

Place the lid on the water butt and secure it. This will keep the water clean and prevent unwanted access.

Maintaining Your 100 Litre Water Butt Set

Regular maintenance will ensure your water butt remains efficient and hygienic. Here are some tips:

  • Clean the Interior: Periodically empty the water butt and clean the interior to remove any buildup of dirt or algae.
  • Check the Diverter: Ensure the diverter and hose are free from blockages and functioning correctly.
  • Inspect for Leaks: Regularly check for any signs of leaks or cracks, especially after freezing temperatures.


Selecting the best 100 litre water butt set for your garden involves considering several factors, including material quality, design, ease of installation, and maintenance requirements. By evaluating these aspects, you can choose a water butt that not only meets your practical needs but also complements your garden’s aesthetics.

Investing in a high-quality 100 litre water butt set is a step towards sustainable gardening. It allows you to conserve water, reduce your environmental footprint, and keep your garden thriving. With proper installation and maintenance, a water butt can serve you well for many years, providing a reliable source of water for all your gardening needs.
