How to efficiently secure your water supply. It’s Important.

 You’ve decided to take a step to be water self-sufficient. It’s a good move. Here are some tips to get the most out of your installation.

Choosing a water tank

 Before you settle on a water tank, you need to consider three things:

  1. How much space have you got for a water tank?
  2. How much water do you need to store? Do you need enough to run your household or just enough to water your garden and top up your pool?
  3. How much water are you going to be able to collect? The larger the roof, the more water will flow into the tank.

It is best to buy the biggest water tank that budget, space and practicality allow. Remember, your tank will need to be installed on a smooth and level surface. Level paving is good enough, but you may have to build a concrete plinth at least 85mm thick or install an adequately designed tank stand.

Maintenance saves you money.

 The suitable rainwater harvesting systems are low maintenance. However, there are a few things you can do to make sure that you protect the quality of your water and extend the life of your system.


 Except for thatched roofs, all rooftops are suitable for water harvesting. Also, it is essential to clean your roof in the dry season before the rains start to protect your water quality. This prevents dust, leaves, animal excrement and dead insects from finding their way into your water supply. Then, check your roof for debris once a month during the rainy season.


Overhanging branches

 Regularly cut back any overhanging branches.


 Keep gutters free from leaves. Installing gutter mesh will make this easier.

Pre-filtration devices

 These devices need to be checked regularly to ensure that they are free from leaves and that rainwater can pass through them.

First flush diverter

 If a first flush diverter is installed, check and clean it out monthly. Ensure that the diverter is dripping out sufficiently to reset the system.

Keeping your tank clean

 Inspect the inside of your tank every three 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.
