Rain barrel systems from Sustain Dane

Rain barrels are a new take on an old design in which cisterns were used to capture the rain hitting and running off the roof of a building. In Madison, Wisconsin (located in Dane County) rain barrel sales constitute one of the programs of Sustain Dane, a non-profit community-focused organization. Since 2006, Sustain Dane has sold more than 1200 of the 55 gallon rain barrels according to the organization’s Web site.

The use of rain barrels results in a number of positive outcomes:

- water is captured for use where the homeowner needs it
- rain water, rather than chlorinated and fluoridated potable water, is used to support landscaping

- reduced demand for potable water saves money and reduces pumping and treatment costs
- less storm water runoff, carrying pollutants and fertilizers, finds its way to the local watershed


Last week, two rain barrel systems – one single and one tandem – were installed at the home of my brother Jaime, who lives in the Dudgeon - Monroe neighborhood of Madison. Jaime purchased the systems for $216 and spent $10 for the cement blocks that serve as the base for the barrels. Jaime also contracted for installation of the systems for an additional $136.


Residents of Madison use an average of 68.6 gallons per person per day at home, according to the City of Madison Water Utility. Residents pay $1.30 per 1000 gallons of water used. So, the decision to install the systems is driven by the positive outcomes cited above rather than by a return on the investment.

While installation is straightforward, requiring only a handful of common tools, there are clear advantages to having someone with experience install the systems. A do-it-yourselfer could install the two systems in less than a day. An experienced installer required 3 hours to complete the job.

Douglas, the installer, arrived at the house driving a van from Community Car, Madison’s car sharing program. He is shown holding a system diverter in the accompanying image. During my 10 years in the solar energy industry in Southern California, I witnessed thousands of solar pool and water heating system installations. With that experience providing perspective, I came away impressed by the clean, efficient and professional installation of the systems.

The 55 gallon barrels, fabricated of recycled food grade plastic, fill quickly even during a relatively light rain. The key component in the rain barrel system is the diverter. Ingeniously designed, it directs water pouring from a downspout into the rain barrel. When the barrel is full, the water is diverted back into the downspout.

The diverter traps debris to keep it out of the barrels; the debris is easily cleared via a removable door on the diverter. Other recommended maintenance includes keeping the gutters clean, occasionally cleaning the barrels with an environmentally safe product and winterizing the system by capping the water input ports on top of each barrel.

Jaime chose to connect soaker hoses to the barrel hose bibs. The soaker hoses utilize the captured water to irrigate about half of the landscaping around his home.

The rain barrels, pictured above, are rather obvious additions to the property due to their size and color (they’re also available in blue). The barrels could be screened with landscaping or other methods, painted, or left in their environmentally chic original look.

Sustain Dane does not ship rain barrel systems because it would not be sustainable to do so. However, they offer a locator at http://www.rainfordane.com/ to help you find suppliers in your area. Check it out.

In addition to the rain barrel project, Sustain Dane encourages citizen involvement in a variety of ways and promotes awareness and understanding of Madison as an eco-municipality. In that context, the organization appears to have embraced The Natural Step framework. I recently discovered that Oshkosh, Wisconsin has also embraced The Natural Step. Look for a post on the subject in the near future.


Post script. In response to this post, I received a comment suggesting that rain barrels would provide a habitat for mosquitos. Paraphrasing from rainfordane.com, the rain barrels are mosquito proof because they are sealed. Let me know if you have had experience in this regard.

Scott with Sustain Dane here. Enjoyed your considered analysis of our RainReserve system. One thing to note is that we do in fact ship the diverter kits nationwide--they come with all the parts needed, even the hole saw for drilling the barrel. You use the barrel locator on the web site to find a barrel.
Regarding installation, I would be surprised if a homeowner required more than about 2 hours to install a single barrel system, even with no experience. Note that the 3 hours quoted was for 2 systems, and even a rookie will be faster on the second with a bit of experience behind him/her.

Hope Jaime enjoys the system!
