4400L Underground Rainwater Harvesting Tank with Direct Pressure Pump

Complete 4400-litre direct pressure rainwater harvesting system for residential properties, delivering harvested water on-demand to multiple points of use.

This integrated system collects and stores rainwater for domestic applications including toilet flushing, washing clothes and dishwashing. Designed for medium-sized installations such as 3–4 bedroom houses, the direct pressure method supplies water to the point of use via an automatic pump that activates when demand occurs. When tank levels drop, mains water automatically tops up the system to maintain capacity for the next rainfall.
