Rainwater Collection a Reliable Water Supply Alternative

A metal silo against a stone wall with greenery around.According to a recent article published byARCSA(American Rainwater Catchment Systems Association), whose mission is to promote sustainable rainwater collectionpractices to help solve potable, non-potable, stormwater and energy challenges throughout the world, a well-designed, installed and maintained rainwater harvesting system can provide high-quality water for potable and non-potable, residential and commercial uses.

Below are some notable findings on rainwater collection compiled by ARCSA from the 2013 Report Card on America’s Infrastructure from the American Society of Civil Engineers, the U.S. Chamber of Commerce and the National Association of Water Companies:

“¢ 7 TRILLION gallons per day are wasted due to 240,000 water main breaks each year
“¢ Over $1 TRILLION is needed over 10 years to repair water systems

ARCSA is the premier national educational and technical rainwater harvesting organization. Decentralized onsite rain and stormwater harvesting systems can deliver a partial solution to our aging water delivery infrastructure and support new job creation.

Rainwater Collection in an Urban Setting


Row of rain barrels connected to a gutter system for water collection.Rainwater collection is becoming increasingly popular for commercial andresidential consumers in urban settings, driven largely by centralized waterunable to meet demands caused by droughts, increased population, along with supplyand demand.

Quality of water is threatened by an aging infrastructure and environmentalconcerns such as the chemical spill in West Virginia last winter. Awareness and concerns of fluorides and chlorine in municipal water supplies areadding to the interest of alternate solutions.

Increased costs to meet storm water management and GSI (green storm waterinfrastructure ) requirements for new construction of commercial andresidential projects are driving owners, designers, engineers, and architects to offset some of the costs involved with implementation.

In a recent report by “the National Resources Defense Council” eight citieswere studied for potential economic impact of rainwater collection. It is estimated the residents of these cities could save 90 million dollars eachyear by adopting simple rainwater harvesting techniques.

Water closet and laundry facilities using rainwater collection are nowbecoming integrated into designs for both commercial and residential application. According to the American Water Works Association,water closetsaccount for approximately 51% of water usage in commercial buildings and approximately 50 % water usage for water closet and laundry facilities inresidential applications.

Commercial Uses for Rainwater Collection


Cherry Valley Dairy building with a visible sign.RainBank Rainwater Systems has been retained to design and build a rainwater collection system for Cherry Valley Dairyin Duvall, WA. 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. (Click to see more aboutCherry Valley Dairyon Facebook and while you’re there, don’t forget to like RainBankon Facebook, too!)

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.
