Tank Filtration
Tank Filtration

Having a quality water tank is only the first step of ensuring the on-going quality of the rain water you harvest and use. To ensure you have the best possible quality of water you should ensure that any debris or dirt is removed from the rainwater you harvest before it is stored in your rainwater tank. Below is a range of "before water tank" and "after water tank" filtration solutions to help you achieve this.

Before Rainwater Tank – Rain heads

If you are only going to install one water quality related accessory in your rainwater system (and we don’t recommend that), you should install a rain head with mesh on each down pipe supplying water to your tank. Quality rain heads have at least a two stage mesh (thicker followed by finer) and should incorporate at least some ability to debris to be washed or blown from the rain head in order to reduce maintenance.

Before Rainwater Tank - First flush

First flush devices divert the first rainwater from your roof to a chamber that slowly releases the dirty water over time. The beauty of a first flush device is that the capacity can be infinitely variable (determined by the chamber length and diameter) so you can adapt it to suit the amount of water you want to divert when it first rains. But like anything else in your rainwater system it requires regular cleaning to ensure that the dirty water empties and it is ready for the next rain that comes along.

Before Rainwater Tank - Whole of Roof

These filters while not cheap can often be more cost effective. Rather than installing a rain head on each downpipe a single whole of roof filter can be installed. You will need to ensure that all supply pipes for the water tank come together as one before the tank in order for the filter to operate effectively

After Rainwater tank - Filters

These are most commonly cartridge filters that are installed between the pump and the outlet. The reason they need to be after the pump is that pumps will have the power to push water through the filter (assuming your pump is appropriately sized) but they will not have sufficient suction to draw water through the filter. The cartridge will need cleaning or replacement from time to time. As it filters and removes particles from the water is will become clogs and provide greater resistance to your pump.

And remember, there is no such thing as a “no maintenance” rainwater system. If you have a swimming pool, would you consider never emptying the skimmer box or pool cleaner? Quality water into a rainwater tanks ensures you get quality water out.
