Rainwater harvesting: actively encouraged, not just permitted

Mississippi places no state-level restriction on residential rainwater harvesting, and the state’s own Department of Environmental Quality promotes rain barrel use as part of its stormwater management guidance.

RuleMississippi
Source water Rooftop or other catchment
Permit required No, at the state level
Permitted uses Non-potable: irrigation and similar uses
State posture Actively promoted by MDEQ's stormwater guidance, not merely tolerated

Where to find it: the Mississippi Department of Environmental Quality (mdeq.ms.gov) publishes stormwater and rain barrel guidance.

Water rights: riparian with a drought-triggered proportional rule

Mississippi water law is built on riparian doctrine: landowners adjacent to a water source may make reasonable use of it, and natural uses like drinking water, livestock, and garden irrigation are generally treated as reasonable by default.

ConceptHow it works in Mississippi
Basic rule Riparian landowners may use any quantity of water so long as it doesn't interfere with other riparian landowners' rights
Drought rule During drought conditions, extraction can be restricted so all riparian owners share the reduced flow proportionally to their stream-bank ownership
Gulf Coast riparian rights Separately defined by statute (Miss. Code §49-15-9) given the coast's tidal and littoral geography

Where to find it: the Mississippi Department of Environmental Quality administers water-related permitting.

Same April 2011 outbreak, a different state's page

Mississippi’s Smithville tornado struck the same day as the Hackleburg-Phil Campbell and Rainsville EF5s covered on Alabama’s page, part of the same nationwide Super Outbreak. This page doesn’t restate that outbreak’s full national data; see Alabama’s Risks page for the broader event context.
