1500 Litres Super Complete Rainwater Harvesting System

The 1500 Litres Super Complete Rainwater Harvesting System is a fully integrated, UK-designed solution that allows homes and gardens to make the most of natural rainwater. Harvesting rainwater reduces household water bills, supports sustainable living and offers a chemical-free alternative to tap water for gardening, cleaning and even toilet flushing—which alone accounts for around 35% of typical household water usage. By diverting and storing rainwater, this system also helps reduce surface flooding during heavy rainfall. Manufactured from high-grade, rotationally moulded MDPE, the underground tank is exceptionally strong, durable and built to last. It features integrated lifting eyes for easier installation and is compatible with standard UK 4" (110mm) pipe fittings. Supplied as a complete package with pump, filter, fittings and pipework, this system provides a reliable, low-maintenance rainwater supply for a wide range of domestic applications.
