Category Rain Barrels & Water Storage

Rain-barrel water is not necessarily safe to drink because roofs and gutters add contaminants. See what collection, treatment, testing, and maintenance require.

Use rainwater for dishes only when it is treated and verified for food-contact use. Learn why untreated roof runoff can contaminate washing and rinsing.

Home water tests can screen for coliform bacteria and sometimes E. coli, but potable-water decisions need certified laboratory testing and careful sampling.

A rain chain can replace a downspout where runoff is moderate and drainage is ready. Compare splash, wind, overflow, attachment, and wall-clearance needs.

A rain chain needs more than a hook: secure the gutter outlet, guide the falling water, limit splash, and provide drainage or a basin at ground level.

Many residential rain barrels need no permit, but state and local rules vary. Check collection limits, plumbing codes, drainage, and storage requirements.

A wooden barrel can store roof runoff for non-potable use if it is sound and watertight. Plan for fittings, overflow, insects, drying, rot, and freezing.

Pair a rain chain with a rain barrel by centering the flow over a screened inlet and planning for splash, wind, overflow, heavy rain, and secure anchoring.

Elevating a rain barrel adds spigot clearance and gravity pressure, but the stand must safely carry the full load. Size the height and support correctly.

RO removes many dissolved contaminants while UV targets microorganisms. Decide whether rainwater needs one or both by testing the source and defining its use.
