Custom Storm Drain & MS4 Marking Stencils
Custom Storm Drain & MS4 No-Dumping Stencils
Reusable municipal stencil systems for no-dumping messages, watershed names, receiving-water information, logos and numbered storm-drain identification programs.
Built from the project requirement—not a generic template
Municipal stormwater programs can involve hundreds or thousands of drains, catch basins and inlets. The exact message is usually controlled by the permittee’s stormwater management program, outreach plan or local standard—not by one nationwide stencil phrase. That variability makes this an ideal bulk RFQ application.
Strong buyers for this application
- Cities, counties and public works departments
- Universities, hospitals, prisons and other non-traditional MS4 operators
- Watershed groups and environmental outreach contractors
- Civil, pavement and municipal maintenance contractors
What to include with an RFQ
- Exact approved wording and language
- Logo, watershed or receiving-water artwork
- Drain, curb or pavement dimensions and surface photos
- Quantity of drains, crews and expected reuse
- Permit, SWMP detail or purchasing specification if available
Stencil construction options
Metal is a strong choice for municipal crews expecting repeated use and cleanup. Mylar can conform more easily to curved curbs or uneven areas. Large programs may use several identical stencils so multiple crews can work at once.
Send the specification and let us lay it out
A useful quote starts with the exact message and total program scale. We can provide a layout proof, suggest panel dimensions and quote duplicate crew kits, phased delivery or replacement stencils.

Existing listings are useful when their sheet sizes fit the job. Large, repeated, multipart or specification-controlled markings should come through the RFQ path.
Questions before ordering
Is storm-drain stenciling federally required everywhere?
No. EPA requires many MS4 operators to implement stormwater programs, but the individual permittee’s plan or local requirement controls whether stenciling is used and what it says.
Can every drain have a different number?
Yes. We can discuss interchangeable character sections, separate number stencils or complete drain-ID schedules.
Can you duplicate a city-approved design?
Yes, when you supply the approved artwork or drawing and authorization to reproduce it.
