Whilst Australia is the driest inhabited continent, we have abundant rainwater along the coast where the majority of our population is concentrated. WaterGroup helps harness this valuable resource. We are leaders in the field of commercial and industrial rainwater harvesting, and regularly present papers on the subject at industry conferences.

Before embarking on any stormwater or rainwater harvesting project, be sure to check our Resources section for our international Guidelines on the Design of Large Rain and Stormwater Harvesting Systems.

Recently, we assisted Woolworths install a 1,000,000L system - one of the world's largest projects of its kind - at their Minchinbury and Wyong sites.

RainHarD, our rainwater harvesting design model, helps us design a system tailor-made for your demands and location, including innovative features such as peak flow diverters - removing the need for tank overflows.

Contact us for a FREE assessment of your site with RainHarD or StormHarD, our stormwater harvesting design model. This is available to all customers looking at storm or rainwater harvesting from collection areas >1,000m2.
