When harvesting rainwater to use as a part of your sustainable gardening routine, there are a few simple steps you can take which will ensure you maintain a safe, clean, and unending supply. Collecting rainwater as it tries to escape through a downpipe is the commonest method, diverting the flow into a tank. It is always best to filter the water at this point for the following very good reasons:
- Filtration removes any leaves or other organic matter from the water, which is great for reducing the risk of disease carry-over and allowing you to use your harvested rainwater on your youngest plants, enabling truly sustainable gardening for all of your leafy friends.
- The filter will stop any algae or sludge from developing inside the tank, preventing the water from turning ‘green’ without using any sort of chemical anti-algae solution.
- Filtering will take out any large particles from the water so that it can be pumped easily and safely, making sustainable gardening easier than ever.
How does a rainwater harvesting filter work?
Firstly, rainwater is taken from the downpipe running from the roof and is channelled through the filter entrance to the sieve cartridge. Here the dirt is rinsed away and into the sewer. The cleaned water is then led through the cartridge’s outlet channel and into storage.
The 4 key cleaning steps for sustainable gardening water
- Filter the water before it is stored in the tank to get rid of any big particles. This will keep blockages to a minimum and provide water of a good enough quality to keep your plants happy and hydrated.
- The calmed inlet stops the particles that settle at the bottom of the tank getting swirled up with the rest of the water, and it keeps oxygen circulating around the tank to keep the water fresh.
- The overflow siphon skims the top layer of the water, where smaller particles like the pollen from your flowers will collect, keeping the water oxygenated.
- The floating intake collects water for your garden from the cleanest part of the tank, which lies just beneath the surface of the harvested rainwater.
