How to stop debris from entering a water tank

If you have a water tank connected to your roof, there are a number of simple precautions you can take to ensure your rainwater is collected and stored in pristine condition.

The first line of defence is to take measures that prevent debris from entering the tank in the first place. This will have the added benefit of reducing the need and frequency of cleaning and maintenance tasks.

A first flush diverter is a simple and practical option that uses rainfall to wash away the debris that collects on the roof and in the gutters during extended dry periods before switching to allow clean water into the tank.

Other recommendations include a sieve for the inlet pipe to prevent larger objects from entering your water tank. This can also be used to trap leaves and other debris which might wash down your roof.

Making sure your tank is properly sealed is also a crucial factor to consider. Failing to properly seal the entrance to your water tank may undo the benefits of a properly screened rooftop collection system and provide easy access for debris and leaves.

Keeping debris out of your water tank is easy, as long as you have the right equipment in place to keep the quality of your water as high as possible.
