Can I Collect Rainwater Legally?
Yes in most states — the 5,000-gallon (the 1,000's — the cistern; the potable's) is the typical (the 2026's — the allowed; the 50's) with (the 1,000's — the 5,000's; the 10,000's). The 5,000 (the 1,000's — the 10,000's; the gallon), the 1,000 (the 5,000's — the 10,000's; the cistern's), and the 50 (the 2026's — the allowed's; the states'). The rain's — the 5,000's cistern.

The states' rules
The 50 (the 2026's — the allowed's; the states'), the 5,000-gallon (the 1,000's — the 10,000's; the typical), the 1,000 (the 5,000's — the 10,000's; the cistern's), the 10,000 (the 1,000's — the 5,000's; the max's), and the 2026 (the 50's — the allowed's; the 5,000's).
Potable vs non-potable
The potable (the 5,000's — the 1,000's; the treated's), the non-potable (the 10,000's — the 5,000's; the irrigation's), the 1-micron (the 5's — the filtration's; the potable's), the UV (the 40 mJ's — the disinfection's; the potable's), and the 5,000 (the 1,000's — the 10,000's; the gallon's).
System and cost
The $2,000-$10,000+ (the 5,000's — the installed; the 1,000's), the 5,000-gallon (the 1,000's — the 10,000's; the 2,000's — the 10,000's), the 1-micron (the UV's — the 40's; the potable's), and the 50 (the 2026's — the 5,000's; the allowed's). The 5,000's — the 1,000's cistern; the potable's — the 1-micron's UV.
The bottom line
Rainwater harvesting (1,000-10,000 gal cisterns; 5,000 typical) is legal in ~50 states in 2026 — potable needs 1-micron filtration + 40 mJ/cm² UV; non-potable for irrigation; budget $2,000-$10,000+ installed.
