2800 Litres Super Complete Rainwater Harvesting System

The 2800 Litres Super Complete Rainwater Harvesting System is a premium, UK-designed solution that helps households significantly reduce water bills, lower mains water consumption and support sustainable living. Harvesting rainwater is not only cost-effective but also environmentally beneficial—natural rainwater is chemical-free, making it ideal for garden irrigation, outdoor cleaning and even toilet flushing, which accounts for roughly 35% of household water usage. By diverting and storing rainwater, this system also helps reduce the risk of localised flooding during heavy rain. Manufactured from high-grade, rotationally moulded MDPE, the 2800L underground tank offers exceptional strength, durability and long-term reliability. Designed for easy installation and low maintenance, it features integrated lifting lugs and compatibility with UK standard 4" (110mm) pipe fittings. With a powerful pump, filtration system, connectors and pipework included, this system provides a complete, high-performance solution for sustainable water use around the home and garden.
