The RainVault® mini system is a variation of the RainVault® model which offers a complete below ground rainwater harvesting system for storage capacities from 3,000L to 7,000L. The precast concrete system is vertically placed, with the only visible surface component being a small bolt down access chamber lid. Both systems contain an inbuilt high quality submersible Grundfos pump which is customised to suit the supply requirement of each project.
The system provides a number of benefits:
- It is fully trafficable.
- It uses proven European technology for optimising water quality.
- It has an automatic backwashing device which eliminates maintenance.
- Its design prevents vandalism and fire.
- It has a bolt-down access lid which provides the ultimate in child safety.
With a minimum service life of 100 years in most ground conditions, the RainVault® mini system complies with all relevant Australian Standards including AS3600 - Concrete Structures Code', WSA128 Buried Rainwater Tanks for Storage of Roofwater' and HB230 Rainwater Tank Design and Installation Handbook'.
