Water Butt Buyers Guide

What to consider before purchasing a water butt  

The market is flooded with these water barrels; all with heavenly promises and opaque language from the manufacturers. No doubt this can leave you confused on which “best” water butt to select – one that fit your need and budget.

Well, don’t be in a conundrum anymore. Just take the following features into consideration and select your way up to into the best water butt for collecting rainwater.

Water capacity

The size of the barrel dictates the amount of rainwater you can collect and recycle. Therefore, take into account your water needs and select accordingly.

The most common water butts are cylinders of 120 litres, but large capacity butts of up to 350 litres do exist. Their range is 100 – 350 litres. There are a few cases of big barrels holding up to 700 litres though.

Note, experts advise settling for a larger water butt especially if your budget and space allow. For it never hurts to have more stored water as with the climate change – there’s no telling the length of the drought period.

BeGreen 100L Capacity Mini Rainsaver Water Butt Kit
If you want a smaller option, BeGreen 100L Capacity Mini Rainsaver Water Butt Kit includes the Butt, Stand and Diverter should suffice. Its compact design makes it excellent for small gardens alongside which you get a decent amount of water (100L). it`s also cheaper compared to the other products.

Water butt construction

Ideally, you want to settle for a water butt that is watertight, easy to clean, durable, lightweight, and that can stand harsh weather; all of which are dictated by its material.  

Note, the most commonly used material is plastic, however, there are barrels made of wood, clay, and stone. The latter categories fall under decorative water butts category some of which are designed to be used as a garden chair.

Now each of these materials has its strengths and weaknesses. For instance, while a plastic barrel is lightweight and cheaper, there is a high chance of such a barrel cracking during winter. This is because when water freezes it expands and the plastic water butt is not elastic enough to take on the additional volume. Thus, select wisely.

Beyond science, it’s advisable to settle for eco-friendly water butts. Those made of combustible or recyclable materials to prevent environmental pollution in the form of landfills and ocean deposits.

And whatever you do, don’t overlook the lid. The lid should be as strong and sturdy as the butt to effectively stop debris, and small animals from falling into the butt and prevent algae growth.  

Rainwater Terrace Water Butt
Looking for a wonderful design? Take a look at the Rainwater Terrace 2 Tier, 134 Litre Water Butt. It comes integrated with self-watering planters alongside fast drain tube taps that serve as water level indicators too.

Shape

This affects the stability of the water butt especially when filled with water. Some barrel shapes can only be stable when installed on a firm, flat surface; otherwise, they will topple when full. That means, it is vital for you to examine the slope of the area you`ll be installing the barrel before settling on a given shape.

Also, the shape dictates the amount of space occupied by the barrel. For instance, a rounded water butt will take up more space than a rectangular-shaped barrel of equal capacity.

The most common ones are barrels of standard shapes, however, there are slimline models designed to fit into narrow spaces. You can go for wall-mounted water butts if the space available is too limiting.

Additional features

Simplicity is key.

Thus, go for butts that are easy to fit and that come equipped with everything you require to install and collect water – including clear instructions on how to go about the installation and water collection.

Also, does the barrel have a stand and a tap at the bottom as that will make it easier to access the collected water?

Again, go for the colour that blend with or in a way complements your surrounding! 

And it goes without saying that the price should be within your set budget.

It would be batter is it has a lever to open the lid and then maybe a place to attach a padlock should you need to lock it.

  4. Clean the roof and gutter regularly or use a rain-sensing mechanism that can keep the first 5 minutes rain off of the cistern especially when there has been no rain for a long time.
