Twin Falls County, ID Trash & Recycling: Illegal Dumping (2026)

County Code section 4-2-3(B)(1) flatly bars throwing, discarding or depositing solid waste or refuse on any premises, improved or vacant, public or private, unless that premises is an official disposal site, and separately prohibits dumping onto any roadway, street, alley, sidewalk or vacant ground, or into any canal, irrigation ditch, drainage ditch or other watercourse. It is also a chapter violation to deposit waste on someone else's property, or to allow waste to accumulate even on your own. Section 4-2-4 gives the county several enforcement tracks for a violation: it can seek voluntary compliance, issue a civil infraction citation, bring a civil action to enforce, enjoin or abate the violation, or pursue criminal prosecution.

On the criminal side, penalties escalate with repetition rather than staying flat: a first violation is an infraction with a fixed fifty-dollar penalty, a second violation within two years is a second-offense infraction carrying a fixed one-hundred-dollar penalty regardless of whether it involves the same waste as the first violation, and a third violation within two years becomes a misdemeanor punishable by up to a one-thousand-dollar fine and up to six months in jail, again regardless of whether the same waste is involved. The code also allows each day a violation continues to be charged as a separate violation, which can multiply exposure quickly for a dump site left in place.
