Filtered Rainwater Harvesting for Gardening
There are a few simple steps you can take when harvesting rainwater to use as a part of your sustainable gardening routine which will ensure you keep your supply safe, clean, and constant. Harvesting rainwater as it travels through a downpipe is achieved by diverting the flow halfway down from the pipe into a tank. It is considered best to filter the water before it travels from the filter into the tank itself:
- Filtering the water will remove any leaves or other organic matter from the water, which is great for reducing the risk of disease carry-over and allow harvested rainwater to be used on even the least mature plants, enabling truly sustainable gardening for the entire garden.
- Filtration will prevent any algae or sludge from growing within the tank, avoiding the water turning ‘green’ without having to resort to chemical anti-algae solutions.
- Filtering the water will take out any large particles so that it is easily and safely pumped, making sustainable gardening easier than ever.
How does rainwater filtering work?
As rainwater is travels down the downpipe running from the roof, it channeled through the filter entrance to the sieve cartridge where the dirt is then rinsed away into the sewer. The clean water is then taken via the cartridge’s outlet channel into storage.
- Filter the water before storing in the tank to remove the larger particles. This keeps blockages down and provides a good enough quality of water for keeping your plants in good health.
- The calmed inlet prevents the particles settling at the bottom of the tank getting mixed up with the rest of the water, and it keeps oxygen circulating around the tank so that the water remains fresh.
- The overflow siphon skims the top layer of the water, where small particles such as pollen will collect, to keep the water oxygenated.
- The floating intake takes water from the cleanest part of the tank, which is just beneath the surface of the water.
