3 Ever 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. This lead to the Urban Sprawl Age. Some of the early incorporation of stormwater engineering is evidenced in ancient Greece. An early specific example of stormwater runoff system design is found in the archaeological recovery at Minoan Phaistos on Crete.

4 SO, WHAT S THE BIG DEAL? Runoff Volumes Increase Pollutants Increase

5 As community grow the volume of storm water discharged from that municipality as well as pollutants generated within the municipal jurisdiction.

6 Storm Water Regulations In 1969, the Cuyahoga River, Ohio caught of fire due to pollution

23 Wastewater Treatment Facility Water Well Ponding Basin 1. Rain and the water that flows over our City flows to ponding basing where it recharges our groundwater aquifer. 2. Water is pumped out of our groundwater aquifer and delivered to homes, schools and businesses. 3. Wastewater leaves buildings where it flows to the City wastewater treatment facility. The primary source of our drinking water is groundwater.
