Why Choose Rain Reserve Garden Tanks?
Rain Reserve garden rainwater tanks bring rainwater harvesting to any Kiwi backyard. Our rainwater storage tanks range from compact 625L models to popular 5700L sizes, designed to fit tight spaces while maximising your water collection potential.
Every rainwater tank includes integrated lids with strainers, BSP outlets, and simple downpipe connection options. Add our downpipe diverter for effortless installation - most homeowners have their system running in under an hour.
Choose from 11 colours to complement your home's exterior.
All tanks are BPA-free, meet AS/NZS 4020 potable water standards, and come with our 10-year no-nonsense warranty. Perfect for garden irrigation, washing cars, and reducing your water bills.
Pro Tip: Start with one tank and see how quickly it fills - you can always add more capacity later. Many customers wish they'd gone bigger from the start!
