Protecting you

Description

Upgrade to a smarter, more sustainable way of using water with the Carat XL/XXL Direct rainwater harvesting system. Designed for seamless integration into your property, this system efficiently collects and utilizes rainwater, reducing dependence on mains water and lowering environmental impact.

Efficient Rainwater Collection and Usage: Rainwater is collected directly from your roof and channelled through downpipes into an underground tank, where it’s first filtered to remove debris. This ensures only clean rainwater is stored, maintaining the quality and extending the system’s life.

Smart Water Supply Management: A mains water top-up unit within the property is designed to supplement the rainwater in the underground tank when levels run low. Controlled by a float switch, this feature guarantees an adequate water supply without manual intervention.

Cost-Saving Installation: Choose the economical gravel backfill option instead of traditional concrete to reduce installation costs significantly—approximately £60 per cubic metre saved. This makes the Carat XL/XXL Direct not only an environmentally friendly choice but also a cost-effective one.

Versatile Installation Options:  The vehicle loading lid can install the system under driveways, optimizing space usage and maintaining garden aesthetics. This feature allows for flexible tank placement, ensuring it fits perfectly into your property’s layout.

Sustainable and Durable Materials: Constructed from 100% recycled plastic, the underground tank reflects our sustainability commitment without compromising durability. This eco-conscious material choice supports environmental stewardship while providing a robust, long-lasting water storage solution.

Advanced Pump Technology: The system is equipped with an automatic submersible pump that includes auto-restart and dry-run protection. It ensures efficient and reliable operation, maintains pressure, and supplies water effectively, minimizing maintenance and worry.

Choose the Carat XL/XXL Direct for a comprehensive, environmentally friendly rainwater harvesting system that saves money, maximizes space, and provides a reliable water supply for your property.
