Rain barrels and rain gardens are legal and encouraged in Waukesha County; there is no county ban on collecting rainwater. In the shoreland zone, rain gardens and infiltration devices count as stormwater treatment that can offset impervious-surface limits.
Wisconsin has no statute prohibiting residential rainwater harvesting, and the county does not require a permit for ordinary rain barrels. In the shoreland jurisdiction, NR 115 lets counties exclude impervious surfaces from the coverage calculation where runoff is treated by rain gardens, infiltration basins, bioswales or similar engineered systems, so harvesting/infiltration devices can actually help you meet shoreland standards. Harvested rainwater should be used for irrigation only, not drinking, and larger cisterns/plumbing tie-ins may need a state plumbing (SPS) review.
No county penalty for basic rain harvesting. Improperly plumbing a cistern into potable systems can violate Wisconsin plumbing code (SPS 382); shoreland stormwater devices must be maintained as approved.
