Presenters Dustan Compton, Arlington's conservation program coordinator, and ACC board president Danny Kocurek will explain how to hook up that nice rain barrel you made or bought, how to use it when it gets full, how to deal with common problems like overfill and how to scale it up.

They will demonstrate a 55-gallon rain barrel, a 600-gallon homemade approach and a 3,000-gallon professionally installed system. They also will show how to deal with gutter debris and overflow, how to calculate how much water to expect, and how to attach devices to use your free water. All of this can be done with a few simple implements, which will be available for a little hand tool hands-on.

Refreshments will be provided, to complement the self-satisfied glow of accomplishment.
