Fully Integrated Water Storage Solution
A combination of rainwater harvesting and municipal backup, our Fully Integrated System is the most sophisticated in the range. The tank is filled with a pre-determined level of municipal water that serves as a permanent backup, while offering the added benefit of harvesting rainwater. The water is then filtered, sterilised and utilised as a full domestic water supply.
Fully Integrated System Benefits
- Uninterrupted/pressured water supply
- Water is filtered and sterilised
- Water can be utilised for full domestic supply
- Reduces reliance on regulated water Saves water
There are three pre-filtration options to improve the quality of the water entering the tank:
3a. Mesh/tank screen (beneath lid)
3b. Rainhead i.e. Leaf Eater
3c. First Flush Diverter
5. Pipes for Rainwater Harvesting – 3 x 110 mm SV pipes
For more detail, refer to the Rainwater Harvesting Components section here.
6. Pipes for Municipal Backup
For more detail, refer to the Municipal Backup Components section here.
7a. 110 mm
7b. Sizes according to pipes
8. Gate Valves
To isolate components and manage the system.
9. Non-return Valves
To ensure no back pressure to the main supply.
10. Float Valve
To control the fill height of the tank (pay careful attention to the height for best results and to ensure that the tank is level).
To improve the quality of water in the tank. The water needs to be filtered and sterilised in order to be utilised for full domestic supply.
Each installation will vary, based on the unique setup and your personal preference. We recommend using a plumber/professional installer, as the system needs to tie into the building’s main water supply line.
In order to prolong your system’s life, reduce the potential for damages and ensure you enjoy maximum benefits, there are some things that you should undertake regularly:
Your rooftop should be cleaned regularly to avoid contamination of the runoff. Dust, leaves, animal excrement and dead insects accumulate on the roof during dry weather. It is therefore important to make sure that the roof is cleaned before the rainy season starts, followed by a monthly check to keep it clean.
2. Overhanging branches
Ensure that branches overhanging the roof are regularly trimmed back.
Ensure that gutters are free from leaves. It is a good idea to consider installing gutter mesh.
Regularly check the pre-filtration device(s) to ensure that it is free from leaves and that rainwater is able pass through.
5. First Flush Diverter
If a First Flush Diverter is installed, check and clean it out on a monthly basis. Ensure that the diverter is dripping out sufficiently in order to reset the system.
6. Keeping your tank clean
Inspect the inside of your tank every 3 months to make sure that leaf litter has not built up at the bottom of the tank. A properly designed system should not allow leaves and other material to enter the tank.
7. Water Quality
Remember that water collected from your roof will not be clean. If you intend to use the rainwater for drinking purposes, consult an installer with experience in installing water filtration systems. For irrigation purposes, however, this water is ideal.
If any filters are installed before or after the pressure pump and/or water tank, please ensure that they are cleaned and/or replaced as per the installer and manufacturer recommendations.
If a UV-light is installed, make sure to replace the globe as per the manufacturer recommendations.
1. Pre Installation
A. Choose a tank
Tank size required for Fully Integrated System = rainwater harvesting calculation + municipal backup calculation.
Calculation for rainwater harvesting:
|ROOF P/M2||TANK SIZE|
|50 - 100||750L - 2200L|
|200 - 400||2500L - 10 000L|
Calculation for municipal backup.
Size of tank = litres p/day x total days backup required.
i.e. 4 x people (600 litres) x 3 days = 1800 litres
B. Tank placement
This will depend on available space, as well as access to suitable guttering/downpipes and the main incoming water supply line.
Tanks must be installed on a sound, level and smooth surface. Level paving will suffice, or a properly designed tank stand. Alternatively, a plinth needs to be built, ideally with a concrete surface bed at least 85mm thick.
D. Recommended Base Sizes
It is recommended that the foundation should be at least 100mm wider than diameter of tank.
1. Base/concrete plinth
Ensure that your tank is installed on a suitable base. The base must be sound, level, smooth, free of any protrusions and at least 100mm wider than the base of the tank (refer to pre-installation).
2. Select pre-filtration
Next, select your desired pre-filtration option(s). This will vary according to preference and the intended use of the water.
3. Install pre-filtration
Install your desired pre-filtration option(s). For detailed instructions, refer to steps 3 to 4 on the Rainwater Harvesting Installation section here.
4. Cut a hole into the lid of the tank
Cut a hole of 110.5mm in the middle of the lid and fit the pipe through the hole, stopping before it reaches the mesh/tank screen.
5. Plumber instructions
For detailed instructions, refer to steps 2 to 5 on the Municipal Backup Installation section here.
6. Install filtration
Install the desired filtration and sterilisation unit between the pump and the house.

Wow, JoJo Tanks you rock! I just spoke to the most friendly, polite, knowledgeable and most helpful customer service lady at your call centre called Lesedi, and she provided all the information I needed about your JoJo Tanks and where to find them. Thank you guys!
On behalf of Rainbow Warriors SA, The Bonecrusher Crew and The Stray Cat Gang, we would like to thank JoJo Tanks for their life-saving donation of a 5000lt water tank to the Rainbow Warriors animal shelter in Hibberdene, Kwazulu-Natal.
For the past five years the Lower South Coast has had severe water problems. This year we were hardest hit and had to endure 16 straight days without a drop of water. As a shelter this becomes a major crisis, as water is like gold to us. Our dogs and cats drink between 80 and 100lt per day, our kennels are washed and scrubbed down each day in order to prevent various diseases that are spread from animal to animal and animal to human.
Unless you have had to face a water crisis day after day, knowing that so many lives depend on you for water, you will never understand just how much this has meant to us.
Thank you once again,
Terence (Tee) Olivier - Rainbow Warriors SA
