5000 Litres Super Complete Rainwater Harvesting System

The 5000 Litres Super Complete Rainwater Harvesting System is a fully integrated, UK-manufactured solution designed to help homeowners dramatically reduce mains water usage, lower water bills and embrace sustainable living. Rainwater is naturally soft and chemical-free, making it superior for garden irrigation, outdoor cleaning and even toilet flushing—which accounts for around 35% of household water consumption. Harvesting rainwater also helps reduce the risk of surface flooding during heavy downpours by diverting excess water into secure underground storage. Made from premium tank-grade MDPE, the 5000L tank is rotationally moulded for outstanding strength and durability, complete with integrated lifting lugs for easy installation and compatibility with UK-standard 4" (110mm) pipe fittings. This complete kit includes everything required for efficient water collection, filtration, pumping and delivery, making it ideal for both home and garden use.
