Why Collect Rainwater?
Rainwater catchment is an eco-friendly and cost-effective method of collecting and storing rainwater for various uses such as irrigation, household needs, and even drinking water with proper filtration. This sustainable water harvesting system involves capturing rainwater from rooftops, driveways and tennis courts, filtering it to remove debris and contaminants, and storing it in water tanks for later use.
Proper installation, regular maintenance, and choosing the right system size are essential for ensuring efficient and safe operation. Rainwater harvesting is a smart solution for both residential and commercial properties looking for water security and to promote sustainability.
When connecting your catchment area to your tank, there are two main systems - Dry and Wet.
Wet System
-
A Wet System (also known as a Charged System) is an efficient rainwater harvesting solution that channels water from multiple roof downpipes into underground pipes, directing it to a storage tank or reservoir.
-
- Maximised Water Collection: Ideal for harvesting large volumes by connecting extensive roof areas.
- Flexible Tank Placement: Perfect for when your storage tank is located far from the catchment area.
Best Applications: Wet Systems are best for new construction projects where underground piping can be easily integrated, ensuring efficient water flow and minimising visible pipes.
-
If you need to harvest large amounts of rainwater or require flexible tank placement, a Wet System is an excellent choice for new builds or projects with substantial water storage needs.
Dry System
-
A Dry System efficiently collects rainwater by allowing it to flow directly from the roof to a storage tank, without storing water in the pipes. The system ensures complete drainage after each rainfall, minimising maintenance and preventing contamination.
-
- Cost-Effective: Affordable installation with minimal plumbing required, perfect for existing buildings.
- Simple Design: Reduced complexity and lower risk of blockages due to no water storage in the pipes.
Considerations: Dry Systems are ideal for short-term rainwater harvesting. For long-term use, multiple smaller tanks may be needed, especially with large or complex roofs.
-
If you're seeking an easy, low-maintenance rainwater collection method, a Dry System is an excellent choice for short-term needs. It’s a practical starting point for a more extensive rainwater solution.
Rain Heads
Aqua Harvest Solutions Rain heads are your first port of call when it comes to filtering out large debris. They are styled with angled screens that are designed to eject leaves and reduce the amount of maintenance required.
Rain heads are important for all systems. They are especially critical on wet systems and charged lines to prevent organic matter build-up in pipes, and prevent mosquitoes from entering your pipework.
First Flush Systems
After a period of no rainfall, debris accumulates on your roof. Once it begins to rain again, this debris will then wash into your system, unless you divert the first flush. Aqua Harvest Solutions First flush diverters play a vital part in any Rain Harvesting system, stopping dirty or hazardous particles and finer matter from flowing into your system, and contaminating your rainwater supply.
