SPEL RainSave® – Rainwater Harvesting & Utilisation Systems

The growing demand and cost of meeting strict drinking water standards is making potable water an increasingly expensive commodity. Many applications do not require potable water and providing the rainwater harvesting and utilisation system has been properly designed and evaluated, quality water can be provided and worthwhile savings in cost.

SPEL RainSave – System and attenuation

SPEL RainSave rainwater harvesting systems are being used in large commercial properties, distribution centers, schools, colleges and large retail outlets by utilising the large roof areas and harvesting the rainwater for toilets, irrigation, vehicle washes, cleaning down operations and industrial uses.
