The objective of this activity is to stencil the message: Dispose no Waste, Drains to Creek, on curbs above storm drains. This activity provides a hands-on action which emphasizes the fact that storm drains are connected to creeks.
In many cities there are two
separate sewer systems, the storm sewer and the sanitary sewer. The sanitary
sewer system collects residential wastewater (from sinks, toilets, washing
machines), commercial and industrial wastewater. These wastes are collected
and delivered to the wastewater treatment plant. The storm sewer system
is made up of a network of pipes which connect gutters and storm drains
to nearby waterways. As rain and melting snow flows over streets, roofs,
and parking lots, water may collect pollutants such as litter, pesticides,
heavy metals and oil. The runoff water is then collected in the storm
sewer system and flows directly to the stream with little if no treatment.
Since both sewer systems discharge waters to the natural environment care
must be taken to prevent or minimize disposal of hazardous wastes into
