How does the Platin Direct Rainwater Harvesting Package work?
Rainwater is collected from the roof of the property and fed into the underground tank via the downpipes. On entry to the tank, the water passes through a filter to prevent any debris from going into the tank. With this system, there is a mains water top-up unit located within the property. This unit supplies mains water to the underground tank when the rainwater level is low.
The operation of this unit is controlled via a float switch. There is a pressure-sensitive pump located in the underground tank. When a valve or tap is opened, water will be pumped under pressure until the valve is closed, allowing the system to repressurise and turning the power off to the pump.
Why choose a Platin Direct Rainwater Harvesting Package?
- Cost-Effective Gravel Backfill: Forego the traditional concrete installations. Our gravel backfill approach can save you approximately £60 per cubic metre, reducing installation costs significantly.
- Flexible Installation with Vehicle Loading Lid: Don’t have enough garden space? No worries. The vehicle loading lid allows for the system to be installed under your driveway, maximising space usage.
- Eco-Conscious Material: The underground tank is made entirely from 100% recycled plastic, reflecting our commitment to sustainability.
- European Market Leader Quality: As a top choice in Europe, this system guarantees reliability and effectiveness in rainwater harvesting.
- Hassle-Free UK Delivery: We offer free delivery across the UK mainland, making your purchase convenient and straightforward.
- Intelligent Water Management: The system comes equipped with an automatic submersible pump, featuring automatic restart and dry-run protection. This ensures efficient and worry-free operation.
- Uninterrupted Water Supply: Unique to this system is the integrated mains water back-up. It automatically tops up the underground tank with mains water when needed, ensuring a continuous supply of water.

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.
