Backflow Testing, Certification & Repair in Rocky Hill Borough, NJ
Rocky Hill Borough is one of New Jersey’s smallest and most historically significant communities — a tiny borough of approximately 700 permanent residents on the Millstone River in southwestern Somerset County. Rocky Hill was the site of one of George Washington’s most famous overnight encampments — Washington and his generals stayed here in August 1783 while awaiting the treaty formally ending the Revolutionary War, and the Rocky Hill Tavern (still standing) served as Washington’s headquarters. The borough’s extraordinary historical significance as the last encampment of the Continental Army, its position along the Millstone River and the D&R Canal State Park corridor, and its beautifully preserved Federal-era architecture make it one of Somerset County’s most historically treasured communities.
South Jersey Backflow provides certified annual backflow testing and certification, backflow repair and rebuild service, and backflow preventer enclosures for Rocky Hill Borough property owners.

Washington's Last Encampment: Extraordinary Historic Context
Rocky Hill Borough holds the remarkable distinction of being the site of General George Washington’s last encampment before the Continental Army was disbanded — Washington’s farewell address to the New Jersey Legislature was delivered here, and the period from August to November 1783 represents the final chapter of the Revolutionary War’s military phase in America. The Rocky Hill Tavern (Washington’s headquarters during this period) and the surrounding historic streetscape are among the most significant Revolutionary War historic resources in New Jersey.
South Jersey Backflow is honored to serve this community of extraordinary historic significance. Properties in Rocky Hill Borough’s historic district — with structures dating from the 18th century — have plumbing systems updated over more than 200 years of continuous occupancy. Annual backflow certification for these historic properties is provided with the care and professionalism that these nationally significant structures deserve.
Delaware and Raritan Canal Corridor
Rocky Hill Borough borders the Delaware and Raritan Canal State Park — the historic Delaware and Raritan Canal that once carried coal and goods through Central New Jersey. The canal corridor’s ecological and historical significance makes water quality protection in this community especially meaningful. Annual certification for Rocky Hill properties contributes to protecting this living piece of New Jersey history.
