Hydrology- Stormwater Management



Managing storm water runoff traditionally has involved collecting and disposing of it away from development to minimize property damage. Cities considered storm water to be a problem during and following heavy rains but often ignored it at other times. However, as the quality of our nation’s water deteriorated, Congress passed and then amended the Clean Water Act requiring states to regulate storm water runoff under the National Pollutant Discharge Elimination System (NPDES) program. Today, storm water management requires management of both the quantity and the quality of storm water runoff, and it is an ongoing program in most municipalities.


USI is also experienced at producing storm water pollution prevention plans (SWPPP) as it is a requirement of all storm water permits. The SWPPP identifies all potential sources of pollution which may reasonably be expected to affect the qualityStormwater Picture of storm water discharges from the construction site, describes practices to be used to reduce pollutants in storm water discharges from the construction site and helps assure compliance with the terms and conditions of the permit.
