Carat Rainwater Harvesting System 2700l, 3750l, 4800l and 6500l
This system is available for inspection at the Centre for Water Saving Technology. We highly recommend inspecting this product, particularly the pump, as the main components are significantly higher quality than anything else on the market.
If you need assistance with tank sizing use our rainwater harvesting calculator here or our garden rainwater tank sizing blog here.
Four main rainwater harvesting packages are offered in four tank sizes and two lid options:
1. Garden Comfort Package for irrigation only
2. Direct Rainwater Harvesting System - the most cost effective solution. A submersible pump maintains pressure and delivers rainwater where it is required. A mains top up unit, tops up the tank if it runs low on rainwater.
3. Indirect Rainwater Harvesting System - the submersible pump tops up a header tank which drains by gravity to feed rainwater to where it is required. The header tank has a mains top up valve if rainwater runs low.
4. Eco Plus Rainwater Harvesting Package - An external pump and console draws rainwater from the tank and deliver it to where it is required. If the tank is low on rainwater a small amount of mains water is delivered to the console and the pump continues to deliver this water.
