Education and Outreach About Storm Drains Many people are not aware that storm drain systems do not treat the water that flows through them. Consequently, many towns have made storm drain marking programs a requirement, as part of their responsibilities toward meeting federal regulations regarding stormwater. Why make storm drain marking part of your community outreach? A storm drain marking event provides an excellent opportunity to publicize the need to keep pet waste, yard waste and household chemicals out of storm drains. Local residents who are involved in the marking program learn about the storm drain system and pollution prevention behaviors. Markers make residents more aware that whatever enters a storm drain goes directly to local waters, and they might be less likely to dump illegally down the drain.
