RainVault™

Product Description

RainVault™ is an underground rainwater reuse system that incorporates modular horizontal cylindrical precast concrete storage components together with specialised pre-treatment filters, calmed inlet, syphoned overflow outlet and floating intake. Submersible or above ground pumps can be used with automatic control switching from rainwater to mains water.

The water treatment train has been developed internationally over the last 15 years with the aim of ensuring an optimum water quality outcome for a range of reuse purposes.

Uses/Applications

The RainVault™ system can be designed for residential reuse or for commercial and industrial sites where large volumes of stormwater are collected from roof or hardstand catchments.

Product Benefits

• Up to 90% reduction in the use of mains water.
• Underground construction provides maximum land utilization and avoids negative visual impact.
• Robust Concrete elements will last a lifetime and allow for shallow installations under traffic loading and  provide optimum resistance to uplift forces associated with flotation in high water tables.
