NYC DEP Notices & Compliance

Rapid, Code-Compliant Resolution for NYC DEP 3-Day and 10-Day Notices

DEP compliance issues require immediate corrective action. A 3-Day or 10-Day Notice signals a confirmed or suspected leak, sewer defect, or service-line issue on the owner’s side of responsibility. Failure to respond can result in water shutoff, fines, and enforcement.
Lady Liberty Contracting Corp resolves DEP notices, violations, and corrective orders by identifying the issue, performing the required water or sewer work, coordinating all permits, and securing final sign-off.

Our process eliminates uncertainty, stabilizes your property, and restores compliance within required timelines.

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.

Credentials, guarantees and permits

What we can show you in writing before any work starts.

Master Plumber in-houseWork is performed under a New York City Licensed Master Plumber on staff — not subcontracted out.
10-year workmanship guaranteeEvery installation and repair is backed by our 10-year workmanship guarantee.
Certified WBEA woman-owned business, certified as a Women’s Business Enterprise.
Is Lady Liberty licensed, bonded and insured?

Yes. Lady Liberty Contracting Corp is fully licensed, bonded and insured for water main and sewer work throughout New York City. Certificates of insurance and licence details are available on request before any work begins.

Who actually performs the work — is any of it subcontracted?

The work is carried out under a New York City Licensed Master Plumber on our own staff, not subcontracted to another firm. That matters on permitted work, because the DEP and DOT filings are pulled under the licence of the plumber responsible for the job.

Do you guarantee your work?

Yes. Every installation and repair carries a 10-year workmanship guarantee. If an issue arises that relates to our work, we come back and put it right.

Do you handle the DEP and DOT permits, or is that on me?

We handle them. Permit filing, inspections and sign-off are managed in-house as part of the job, including street-opening permits and the restoration that follows.

Do you offer financing or payment plans?

Yes. Water main and sewer replacements are large, unplanned expenses, and payment options are available. See financing and flexible payment options.

What kind of work do you take on — and what don’t you?

We work on the water and sewer lines that connect a property to the city main: service line repairs and replacements, sewer laterals, excavation, DEP and DOT permitted work, and the street and sidewalk restoration afterwards. That covers residential, commercial and municipal properties across all five boroughs. We do not take on interior plumbing — in-house leaks, fixtures, heating or boiler work.

What a DEP 3-Day or 10-Day Notice actually means

A DEP notice makes you responsible for the water pipes connecting your building to the water main under the street. That section of pipe belongs to the property owner, not the city, so the repair, the permits and the inspection are all yours to arrange — and the clock on the notice is measured in business days, not calendar days.

How long do you actually have?

NoticeTime to complyIf you do not
3-Day Notice 3 business days A $1,000 fine on your next water bill, a 10-Day Notice, and shut-off of your water service
10-Day Notice 10 business days Water service is shut off when the notice is served and stays off until the repair is complete

Because the count is in business days, a notice served on a Friday runs to the following Wednesday, and public holidays push it further out. The $1,000 charge is applied once; it does not increase again at the 10-day stage.

Who is allowed to do the work?

The repair must be made by a plumber licensed by the Department of Buildings to work on pipes beneath the ground. That plumber pulls the DEP and DOT permits, coordinates the inspection, and notifies DEP when the defect is corrected — which is what triggers your water service being restored. A general indoor plumbing licence is not sufficient for work on the service line.
