Some key components of a rainwater system:
- Course screen to filter out large debris.
- First flush device to remove the first .5-1mm of rain off the roof. This contains the highest level of contaminants and is best re-routed into your landscape rather than being stored.
- Additional gravity filtration if your rainwater is used for indoor non-potable or outdoor drip irrigation. These filters vary in mesh size and often two filters are used, one course and one finer.
- Level tank or tanks as per your design with all of your fittings planned out, you need and inlet, overflow, and an outlet. It’s important that all the connecting pipe work be carefully planned in order to look as discrete as possible, and operate effectively and safely.
- A pump will most likely be required to pressurize your water lines unless you wish to use a gravity drip irrigation set-up. It is important that all of your taps, valves, and water lines indicate that the water is not for potable use.
