Storm Drain Kit

What is a Storm Drain Marking Kit?

Use our markers to add a pollution prevention message to your neighborhood storm drains. Kits include the markers, maps and the tools needed to attach the markers to the storm drain covers. We appreciate your concern about your neighborhood and that you are willing to assist in educating your neighbors and the public about stormwater pollution prevention. Stormwater pollution — water pollution that is carried from our yards and streets by rain runoff — is easy to prevent!

Make sure everyone in your neighborhood knows that storm drains are only for rain — not oil, not grass clippings, not leaves, not fertilizers, not litter, not pet waste. Marking storm drains is a great civic activity for scouting groups and civic organizations.

Storm Drain Marking Instructions

Thank you for providing an important community service for the city. Storm drain marking helps to educate the public on the need to prevent stormwater pollution at the source. These signs raise awareness about the connection between storm drains and receiving waters and can help to deter littering, excess fertilizer use, dumping, and other practices that contribute to stormwater pollution.

A storm drain marking kit contains enough safety vests for all on the team, plenty of adhesive tubes, a caulking gun, a wire brush, a pair of snips to open adhesive tubes, a piercing wire (to pierce inside seal on tube), a hammer and chisel (to remove old markers if needed), rags (to help keep things clean) and the storm drain signs.

Safety is the Number 1 Concern

  • Always wear the safety vests while marking the drains.
  • Marking the drains should be done in teams of at least two (2) so that one may watch for traffic. Adult supervision is necessary with children.

Clean Storm Drain Lid

  • Make sure the storm drain lid is flat, dry and free of loose debris
  • The sign should be centered on the storm drain lid about 6” to 12” from the street edge. Use the brush provided to lightly scrub the surface where the marker will be placed and sweep the loose debris away from the storm drain lid
  • Note: If old signs need to be removed, use the hammer and chisel to pry off the old signs and then follow these cleaning instructions.

Prepare Storm Drain Placards

  • If the signs have a protective backing, peel it off.


  • Prepare caulk gun by cutting about ½ of an inch off the end of adhesive tube and pierce inside seal of tube using the piercing wire. Pull back handle of glue gun, insert tube and push the handle back in.
  • On the back of the sign, place a line of adhesive around the edge about one inch in from edge. Then draw an X in the middle from one corner to the opposite corner. The adhesive line should be about a quarter of an inch thick. After applying the glue, pull back on the handle to release pressure on the adhesive (or it may continue to come out).
  • Be careful using the adhesive as it can be messy and is tough (more likely impossible) to get off of clothes and hard to get off your hands.

Apply Sign To Drain

Attaching the Sign

  • Position the sign over the storm drain lid so that the writing can be read from the street. It should be centered on the storm drain lid about 6” to 12” from the street edge.
  • Press sign firmly into place and use a rag to wipe away excess adhesive.
