Commercial Uses for Rainwater Collection

The goal is to collect and treat enough rainwater to mitigate the farm’s city water usage by 100%. Currently the farm uses over 7,500 gallons monthly for watering the livestock and milking equipment wash down. With over 12,000 square feet of roof area and approximately 36 inches of annual rainfall, that’s over 269,000 of available rainwater – more than enough to supply the farm’s usage.

RainBank is pleased to see more innovative uses of rainwater collection in the Pacific Northwest. As the economy is growing again, businesses are looking for ways to save on operating costs. With large roof areas and high use operations such as the dairy, commercial customers are recognizing that a return on investment can be achieved in a realistic time frame. Their customers appreciate the “echo friendly” approach to the production of their goods and products.

RainBank is looking forward to working with Cherry Valley Dairy and supports their business approach to be the first in the area to use rainwater collection as their water source.
