Rainwater Harvesting

We Tried It: 7 Steps To Rainwater Harvesting Using A JoJo Tank

Rainwater harvesting is a simple and effective way to collect and store rainwater for later use.


  • As South Africa continues to face challenges related to water scarcity and climate change, rainwater harvesting has emerged as a sustainable solution to address the growing demand for water.
  • By collecting and using rainwater, we can reduce our dependence on traditional water sources and conserve water resources for future use.
  • Whether you are looking to save money on your water bill, reduce your environmental footprint, or simply have a water back-up, rainwater harvesting is an excellent option to consider.

Right now, the dry Winter months seem like a long way away, but water limitations from June to August are a reality for many gardens and households in greater Sandton. Much like curbing load-shedding, installing a rainwater harvesting solution to keep gardens watered or adapting this for household use, is becoming an essential feature that will also enhance the value of your residence. Whilst this might seem like a very involved and costly project, it’s actually much easier and cost effective than you might think.


Putting it to the test, The Sandton Times set out to install a JoJo tank, a brand of water storage tanks that have become a household name in South Africa. These tanks are popular due to their durability, affordability, and versatility. They are commonly used to store water in both residential and commercial settings, and are especially useful in areas where access to a reliable water supply is limited.


Available in a range of colours and aesthetically designed to integrate into any environment, JoJo tanks are a popular water storage solution and come in various sizes, made from high-quality, durable materials that can withstand harsh weather conditions.


Using an accredited installer, the process took 2-weeks (to allow for the tank foundation to dry and set properly) and the final results have been a game changer in keeping the garden well-hydrated. In this post, we’ll go over the steps in the JoJo tank installation process, be it for a home or garden:


Step 1: Choosing the Location
The first step to installing a JoJo tank is to choose the location. You’ll want to find a spot that is level and stable. The ground should be compacted and free of any rocks or debris. The location should also be close to a downspout or a source of water. Make sure to check local regulations, body corporate rules and obtain any necessary permits before installing the tank. It’s best for the JoJo tank to be situated in the garden and connected to a downward gutter pipe to efficiently funnel rainwater into the JoJo tank.


Step 2: Preparing The Base
The base is an essential part of the installation process. The base provides a stable surface for the tank and helps to distribute the weight evenly – when selecting space for the tank, factor in the space for the base. For smaller tanks, you can use a concrete slab or pavers as a base. For larger tanks, you may need to excavate the area and pour a concrete pad.


Step 3: Installing The Tank
Once the base is ready, and this could take up to a week to dry and set, it’s time to install the tank. Depending on the size of the tank, a few people might need to lift and position the tank. Place the tank on the base and make sure it’s level. Use a spirit level to check the tank in all directions. Select a suitable colour for the environment it will be living in!

Step 4: Connecting The Inlet
The inlet is the part of the tank that connects to the downspout from the gutter or source of water. This connects the inlet to the tank using a PVC pipe and fittings. Make sure the connection is tight, aligned and secure. If the tank is going to be used for rainwater harvesting, a first-flush diverter will be part of the setup to remove any debris or pollutants from the water.


Step 5: Connecting The Overflow
The overflow is another important part of the tank. The overflow ensures that excess water flows out of the tank and away from the foundation of your home or property. The overflow will be connected to the tank using a PVC pipe and fittings. Make sure the connection is tight and secure. A leaf strainer will also be part of this installation to prevent leaves and debris from entering the overflow.


Step 6: Connecting The Outlet
The outlet is the part of the tank that connects to a tap or irrigation system. This will be connected using a PVC pipe and fittings. Make sure the connection is tight and secure. You may want to include a filter to remove any sediment or debris from the water. In addition to the above, it is also good to look at getting a gage so you’ll be able to see how much water is in the tank at any time as well as getting the additional pump option, which will provide solid water pressure to the water coming out of the tank, ensuring good water distribution.


Step 7: Testing The Tank
Once the tank is installed and all the connections are made, it’s time to test the tank. Fill the tank with water and check for any leaks or drips. If you notice any leaks, tighten the connections or replace any questionable parts. It’s important to check the tank periodically for leaks and to make sure the connections are secure.


Testing the tank for leaks and drips is an important final step to ensure that your JoJo tank is functioning correctly. Overall, installing a JoJo tank is an uncomplicated and effective way to store water on your property. With an experienced installer, you can have your JoJo tank up and running in no-time, who will choose a level and stable location, prepare a solid base, and connect the inlet, overflow, and outlet properly. Alternatively, you could always give the installation a try yourself!
