How the NYC DEP Compliance Process Works

1Notice Review and Scope Identification

We read and interpret the notice, identifying required actions, deadlines, and whether the issue relates to the water service line, house sewer, or both. Crews verify responsibility (city vs owner), review site conditions, and determine whether repair or replacement is mandated.

2Permits, Approvals, and Utility Mark-Outs

Most DEP-driven corrective work requires DEP permits, DOT street/sidewalk opening permits, and full utility mark-outs (gas, electric, telecom). We coordinate every required approval to keep the project moving within DEP deadlines.

3Correction of Water Main or Sewer Defect

Once permits are cleared, our team performs the required work: Water service line repair or replacement Sewer line repair or replacement House trap replacement Disconnection for demolition Leak elimination and section replacement All repairs meet NYC plumbing code and DEP compliance criteria.

4Inspection and Verification

DEP or DOB may require inspections to confirm the work meets city standards. We schedule, host, and document all inspections to ensure smooth approval.

5Final Sign-Off and Compliance Closure

After inspection approval, we submit necessary documentation and confirm closure of the violation. Property owners receive written compliance proof for records, insurance, or future filing needs.
