Rainwater Harvesting Tanks for Toilet Flushing


Crane lifting equipment near a building with safety cones around.RainBank is honored to be currently building two 18,000 gallon rainwater collection tanks for the Army Corps of Engineers at Joint Base Lewis-McChord, WA. Both tanks will harvest rainwater to be used forfor wash down and toilet flushing.

Rainwater Collection a Reliable Water Supply Alternative

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.
