Stormwater Management Is a Must for Urban Communities

Stormwater Management is needed for runoff as water generated from precipitation, rain and snowmelt events flows over land or paved surfaces and does not absorb into the ground. As the excess runoff flows, it accumulates debris, chemicals, sediment or other pollutants that could adversely affect water quality. The federal Clean Water Act, Safe Drinking Water Act, and Endangered Species Act requires cities to manage stormwater runoff to protect water quality in rivers and streams, protect watershed health, and protect groundwater as a drinking water resource.

The primary method to control stormwater discharges is the use of Stormwater Management practices (BMPs). Most stormwater discharges are considered point sources and require coverage under a state NPDES (National Pollutant Discharge Elimination System)permit authorized by the EPA.

EPA Stormwater Management Guidelines

A highly recommended Stormwater Management Program is the the EPA Storm Water Management Model (SWMM) which is a dynamic rainfall-runoff simulation model used for single event or long-term simulation of runoff quantity and quality from primarily urban areas. The runoff component of SWMM operates on a collection of sub-catchment areas that receive precipitation and generate runoff and pollutant loads. The routing portion of SWMM transports this runoff through a system of pipes, channels, storage/treatment devices, pumps, and regulators. SWMM tracks the quantity and quality of runoff generated within each sub catchment, and the flow rate, flow depth, and quality of water in each pipe and channel during a simulation period comprised of multiple time steps.  Consider using grey water recycling with a Rainwater Harvesting System!

Residential Storm or Rainwater Management

The landowner or homeowner can do their own part in Stormwater Management byminimizing runoff from their property, such as:

• Use permeable paving surfaces such as wood decks, bricks, and concrete lattice to allow water to soak into the ground. Where possible, direct runoff from paved surfaces across vegetated areas.
• Allow "thick" vegetation or "buffer strips" to grow alongside waterways to filter and slow runoff and soak up pollutants.
• Plant trees, shrubs, and groundcover. They will absorb up to fourteen times more rainwater than a grass lawn and they don't require fertilizer.
