Rainwater harvesting is legal throughout Bergen County and New Jersey. There is no state or county prohibition on residential rain barrels. NJDEP encourages capture as a stormwater best management practice under NJAC 7:8.
New Jersey law does not restrict private rainwater collection, and Bergen County has no countywide ordinance limiting residential rain barrels or cisterns. NJDEP's Stormwater Management rules at NJAC 7:8 actively promote rainwater harvesting, rain gardens, and green infrastructure as best management practices for new development. Larger non-potable cisterns and any indoor connections must comply with the New Jersey Plumbing Code (NJAC 5:23-3.15) to prevent cross-connection with potable supply. Bergen County Soil Conservation District reviews stormwater management plans for major development. Homeowners installing simple barrels under downspouts face no permit requirement.
Improper indoor cross-connection can trigger plumbing code violations under the Uniform Construction Code, and unauthorized stormwater discharges may draw NJDEP penalties under NJSA 58:10A-10.
