Since humans began living in concentrated village or urban settings, stormwater runoff has been an issue. During the Bronze Age , housing took a more concentrated form, and impervious surfaces emerged as a factor in the design of early human settlements. Some of the early incorporation of stormwater engineering is evidenced in Ancient Greece. A specific example of an early stormwater runoff system design is found in the archaeological recovery at Minoan Phaistos on Crete.

This water is referred to as stormwater or stormwater runoff. Stormwater runoff has been identified as the number one cause of pollution to rivers and streams, the source of our drinking water. In areas with combined sewers, a single pipe carries both stormwater from streets, houses, and businesses as well as waste water from houses and businesses to a water treatment plant. During dry weather, the combined sewer system and wastewater treatment plants have the capacity to transport and treat all the wastewater entering the system, but when there is a lot of rain or snowmelt, the combined runoff and sewage may overwhelm the system, filling the pipes faster than our treatment plants can clean it, and overflowing into our rivers and streams. Waterways where a combined sewer outfall is overflowing, or has overflowed in the last 24 hours, are unsafe for any type of recreation.
Why is stormwater pollution a concern? It is of concern for two main issues: one related to the volume and timing of runoff water and the other related to potential contaminants that the water is carrying from human and animal activities. These contaminants are picked up as water from a storm or garden hoses and sprinklers drain from streets, parking lots and lawns and enter the system through our catch basins and storm drains. From there, they are transferred straight to rivers and streams untreated.
Anything that is dumped or dropped on the ground or in the gutter contributes to stormwater pollution. Much of it is not biodegradable and is harmful to marine life and cleanliness of our water that we swim in and drink. Is stormwater treated before it reaches the river? Stormwater systems flow directly into the rivers, lakes and streams. The cost of treating stormwater would be so high that it would exceed available resources. Is there a difference between a storm drain and a sewer drain? They are two completely separate drainage systems. The sewer system takes all household wastewater from toilets, showers and sinks and routes it through your plumbing system and directs it to a treatment plant. The storm drain is intended to route rainwater quickly off the streets during a heavy storm.Contact Us. Stormwater Pollution.
