Rockville Plumbing Oversight: WSSC vs. City of Rockville
Rockville is unique because water and sewer oversight depends on the specific property location, not just the city address:
✓WSSC-served properties follow WSSC permitting, inspection, and compliance requirements.
✓ City of Rockville–served properties follow City of Rockville plumbing permits, inspections, and municipal codes.
Important: Using the wrong authority can result in failed inspections or rejected permits. Durance Plumbing routinely works with both WSSC and the City of Rockville and determines the correct governing authority before work begins.

Working Within Regulatory Guidelines
Both WSSC and the City of Rockville regulate plumbing work to protect public health and the drinking water system. Their guidelines affect many common plumbing projects, including:
✓ Permit requirements for plumbing work
✓ Inspection and approval procedures
✓ Backflow and cross-connection protection
✓ Pressure regulation and safety devices
✓ Approved materials and installation methods
Our familiarity with both regulatory systems helps prevent delays, failed inspections, and enforcement issues.

👥 WHY CHOOSE A PROPERLY LICENSED PLUMBER IN ROCKVILLE
Hiring a plumber licensed for the correct governing authority matters because:
✓
Not all plumbers are authorized to work under both WSSC and City of Rockville rules
✓
Incorrect permitting can delay or invalidate inspections
✓
Non-compliant work can result in fines or required corrections
Durance Plumbing’s dual licensing ensures your plumbing work is completed correctly and in compliance with the appropriate authority.
