BlueBarrel Rainwater Catchment Systems
Rainwater Harvesting System
This western Santa Rosa home demonstrates just how much you can do with rain barrels on a small suburban lot.
With rain catchment systems collecting from three separate downspouts on the 1,350 square foot home, an interconnected 3-barrel system, 7-barrel system, and 8-barrel system make for a total of 18 barrels and 990 gallons of water storage tucked discreetly along the sides of the house. With continual drawdown and recharge during the rainy season, the total water savings is hard to estimate, but it is much more than 990 gallons annually, especially when there are dry-stretches between rainstorms, as is typical in California.
The daisy-chained barrel systems featured on this site are a great fit for small-to-medium-sized lots. Beginners can get started with just a few barrels and add on gradually, surprising themselves with just how much high-quality water is available when you are prepared to collect it, even in drought years.
A 3-barrel system in the front waters an ornamental landscape of bunch-grasses and salvia through an automated, gravity-fed drip irrigation system.
Side & Back System
An 8-barrel system on the west side irrigates the edible garden in the back. Rainwater is also used for starting seasonal vegetables, the main focus for these suburban gardeners, and for the occasional deep watering of the fruit trees on the property.
An additional 7-barrel system on the east side provides backup water for hand watering, system recharge, and other non-potable needs.
These homeowners could certainly connect more barrels, and they plan to do so! For now, collected rainwater typically lasts them through July, and they switch to city water for the tail end of summer until it starts raining again.

Rainwater Is The Best Water
Plants do much better when irrigated with rainwater (especially potted plants!). Rainwater is free of the salts, chemicals, and heavy minerals found in other water sources, and it naturally has optimal pH balance and nitrate delivery.
Rainwater Is Abundant
You get over 600 gallons of high quality water for every single inch of rain falling on a 1,000 square foot surface. This makes rainwater harvesting a common sense water conservation technique, even in dry climates.
