How to install a RotoTank™ Rainwater Harvesting Tank

The specific steps for installing a rainwater harvesting tank can vary depending on factors such as the size and type of tank, the location of the installation, and local regulations. However, the general steps for installing a rainwater harvesting tank are:

  1. Choose an appropriate location for the tank, ideally near a downpipe or other source of rainwater.
  2. Level the ground where the tank will be placed.
  3. Install a base of compacted gravel or concrete to provide a stable foundation for the tank. Make sure your finished platform is 100% level, with no loose stones or sharp objects protruding.
  4. Install the tank according to the manufacturer’s instructions, making sure that all connections and fittings are secure. Do not over tighten the fittings, this may cause the internal nut to loosen, resulting in a leak. Use flexi hose and fittings, not rigid piping as this can lead to long term damage to the base fitting and tank.
  5. Install a leaf catcher and a first-flush diverter to prevent debris and pollutants from entering the tank. This can be mounted to the wall next to your tank. Empty this system after big rains, to clean the tank and prevent back flow of debris.
  6. Connect the tank to a distribution system that will allow you to use the harvested rainwater for irrigation, washing, or other non-potable uses. This can be in the form of a standard tap, or a pump interconnected to your inline house feed.
  7. If you wish to use a water pump, get the right advise on the size required for your home, the height of your property and number of taps you wish to use at any given moment will influence your requirements.
  8. Pump covers are recommended to protect your pump and electrical wires from the natural elements.
  9. We would advise a filtration system to be placed on the inline feed if you are considering using the water for drinking purposes. Alternatively boiling the water is a must.
  10. Consider installing an overflow system to prevent water overflowing in heavy rains close to your home,  the pipe should be angled away from the property, down hill if possible, preventing water flowing back towards your foundations.
  11. Depending on local regulations, you may need to obtain permits or have the installation inspected by a professional
