Slimline Rainwater Harvesting Systems (800 Litres - 4,000 Litres)

Compare slimline rainwater storage options from 800 to 4000 litres, including an 800 litre tank-only model and complete systems with pumps and filters. The range covers 800, 1600, 2400, 3200 and 4000 litre system capacities, giving you a choice of storage volumes for the available installation space.
Start with the space available for the tank or tanks, the roof collection area and the amount of stored rainwater you expect to use. Then check the selected system’s dimensions, pump specification, filter capacity and supplied connections. A larger storage volume should be assessed alongside practical access, installation and maintenance requirements.
The tank-only option suits projects where pumping and filtration are being specified separately. Complete kits bring these components together, but the exact contents vary by product. Read the individual listing before ordering and confirm that the system is suitable for the intended non-potable application.
We also supply 1500 litre utility tank systems and rainwater filters and tank accessories. Contact our team if you need help comparing configurations.
