Step into the future of sustainable living with the Platin AA Silentio Rainwater Harvesting System, a pinnacle of innovation from GRAF, the European market leader. This advanced system is designed to fulfil your non-potable water household needs, from toilets and washing machines to garden irrigation and outdoor cleaning.
How It Works:
- Rainwater Collection: Rainwater is efficiently captured from your roof, travelling through downpipes to the underground tank.
- Advanced Filtration: As the water enters the tank, it passes through an award-winning filter, ensuring debris-free storage.
- Efficient Water Management: The system includes a pump and control unit within your property that smartly draws water from the tank on demand.
- Mains Water Integration: When rainwater levels are low, the system seamlessly switches to mains water, stored in a cistern under the pump, ensuring uninterrupted water supply.
- Maximised Rainwater Usage: The unique design prevents mains water from topping up the underground tank, maximising rainwater harvesting.
- Digital Level Indicator: A digital indicator in the tank ensures precise monitoring and control of water levels.

It's essential to inform your local water authority before starting any work. According to the Water Supply (Water Fittings) Regulations, installing systems like rainwater harvesting is considered a "material change of use" of your premises. This means you must notify your water undertaker in advance and obtain their consent before beginning the installation.
To notify your local water authority, you'll need to provide details such as your name and address, a description of the proposed work, and specifics about the location and intended use of the premises. Many water undertakers have their own notification forms available on their websites. It's important to use these forms, especially when submitting electronically.
By following these steps, you help ensure that your rainwater harvesting system is installed safely and in compliance with regulations, protecting both your water supply and the broader public system. For any further guidance, please click here.
