Stormwater

 

What is Stormwater?

Stormwater refers to rainwater or snowmelt that travels over impervious land surfaces as runoff. Stormwater pollution results when this runoff picks up, carries and transports various pollutants (oil, grease, chemicals, sediment, nutrients, pathogens) along streets, drains, open channels, and storm sewer systems. This runoff is eventually discharged untreated into nearby water bodies. However, in combined sewer systems, stormwater flows with sewage to a wastewater treatment plant.

In urban areas, stormwater management is especially important due to decreases in natural land cover and the expansion of impervious surfaces, such as rooftops, sidewalks and roadways. These surfaces exacerbate runoff because they change the permeability of the landscape—preventing rainwater from soaking in or infiltrating the soil. Some of the impacts of stormwater include flooding, sewer overflows, and nonpoint source pollution.

Stormwater is managed using storm sewers as well as stormwater controls, which include green infrastructure and low impact development.

Recent Stormwater Report Features

Ramping Up Erosion Control Training for Transportation Projects 
Colorado Department of Transportation's new erosion control training is complimented by a newly renovated facility for hands-on learning.
 
Innovative Financing Accelerates Stormwater Management 
Philadelphia and Washington, D.C. use innovative financing mechanisms to expand green stormwater infrastructure and meet water protection goals.
 
Monitoring and Modeling: Two Sides of a Coin 
Colorado is a headwaters state with pristine water quality from mountain streams. Low impact development (LID) is viewed as an option for maintaining those healthy waters and meeting high goals for receiving waters.
 
Moving Dirt: Challenges in LID Construction 
Use of low impact development (LID) is growing in both new developments and retrofit projects. This increase also means a growing need for contractor experience related to unique stormwater management requirements of LID.
 
Eleven Lessons Learned from Fairfax County’s Flood Response Program 
Learning from experience, Fairfax County stormwater engineers have identified 11 lessons that are important to the success of any flood response program.
 
Through the Rapids: The Rocky Ride of the Stormwater Rule 
 Seth Brown, WEF stormwater program and policy director, discusses possible reasons and implications for the national stormwater rule not moving forward.

Books 

 Green Infrastructure Implementation 
The book provides actionable information promoting the implementation of green infrastructure. Unlike most publications, which focus on technical design of individual green elements, this peer-reviewed book tackles topics related directly to the ability to implement green infrastructure
 
 Wet Weather Design and Operation in Water Resource Recovery Facilities 
This peer-reviewed publication provides water professionals with a comprehensive reference of current design and operational practices for managing the unique challenges associated with wet weather flows.
 
User-Fee-Funded Stormwater Programs   
A must-read for agencies and public works departments interested in developing charge systems for stormwater programs based on fee structures.
 
Design of Urban Stormwater Controls (MOP 23) 
Developed by WEF and ASCE, this MOP focuses on consolidating technologies under a comprehensive view of stormwater management in an attempt to foster a convergence between traditional stormwater controls and green infrastructure.
