What is a stormwater treatment area?
Stormwater treatment areas (STAs) are constructed wetlands divided into flow-through treatment cells that remove nutrients from agricultural and urban runoff water. The nutrients are consumed through plant growth, and captured by accumulation of dead plant material in a layer of sediment. STAs were introduced around the Everglades National Park in an effort to reduce …
What is the history of stormwater engineering?
Stormwater, also spelled storm water, is water that originates from precipitation (), including heavy rain and meltwater from hail and snow.Stormwater can soak into the soil and become groundwater, be stored on depressed land surface in ponds and puddles, evaporate back into the atmosphere, or contribute to surface runoff.Most runoff is conveyed directly as surface water …
Why don’t stormwater treatment facilities work?
Feb 15, 2022 · The NPDES stormwater program regulates some stormwater discharges from three potential sources: municipal separate storm sewer systems (MS4s), construction activities, and industrial activities. Operators of these sources might be required to obtain an NPDES permit before they can discharge stormwater. This permitting mechanism is designed to ...
Where does stormwater go after it is collected?
Mar 01, 2021 · When buildings, parking lots, roads and other hard surfaces are added to the landscape, the ground cannot absorb the water. Water from rain or snow storms, known as stormwater, instead flows over streets, parking lots and roofs and into a water body or storm drain. Stormwater runoff is often worsened by human activities, and can contain nitrogen and …
What stormwater means?
Stormwater is water that comes from precipitation and ice/snow melt – it either soaks into exposed soil or remains on top of impervious surfaces, like pavement or rooftops. Stormwater will eventually evaporate off of a level surface, but most often it flows as runoff to another location.
What is an STA in Florida?
Stormwater Treatment Area 1 East (STA-1E) The stormwater treatment areas are man-made wetlands designed to clean up nutrients primarily from surrounding agricultural areas before the runoff reaches the Everglades. Levees and canals ring the perimeter of the treatment areas.
Is stormwater one or two words?
one wordThe industry has generally adopted the use of “stormwater” as one word.May 22, 2020
What does stormwater runoff mean?
Stormwater runoff is generated from rain and snowmelt that flows over land or impervious surfaces, such as paved streets, parking lots, and building rooftops, and does not soak into the ground.Mar 21, 2022
How does an STA help clean pollutants out of the water?
Periphyton, which includes algae or bacteria found on or in the emergent and submerged vegetation, are another very important component of STAs that remove nutrients from the water. Typically, water is moved first through cells with emergent vegetation, then through cells with submergent vegetation.

What is stormwater and where does it originate from?
Stormwater, or rainwater runoff, is rainwater that runs off land and moves away from the area where it originally falls. In urban or built up areas, it is best defined as rain that runs off surfaces where water cannot penetrate such as roofs, driveways and roads.Jan 6, 2021
Is stormwater on word?
Stormwater as One Word That document exclusively uses stormwater as a single word, as do the other permits. The EPA website isn't so consistent, however.Oct 18, 2018
How is wastewater produced?
Wastewater is the polluted form of water generated from rainwater runoff and human activities. It is also called sewage. It is typically categorized by the manner in which it is generated—specifically, as domestic sewage, industrial sewage, or storm sewage (stormwater).
How does storm water get polluted?
Stormwater pollution results from materials and chemicals washed into the storm drains from streets, gutters, neighborhoods, industrial sites, parking lots and construction sites.Jan 4, 2022
Why does run off get polluted so easily?
Runoff is a major source of water pollution. As the water runs along a surface, it picks up litter, petroleum, chemicals, fertilizers, and other toxic substances. From California to New Jersey, beaches in the U.S. are regularly closed after heavy rainfall because of runoff that includes sewage and medical waste.Jan 21, 2011
Why are runoffs important?
A portion of the precipitation seeps into the ground to replenish Earth's groundwater. Most of it flows downhill as runoff. Runoff is extremely important in that not only does it keep rivers and lakes full of water, but it also changes the landscape by the action of erosion.Jun 6, 2018
Where does storm water come from?
Stormwater, also spelled storm water, is water that originates from rain, including snow and ice melt. Stormwater can soak into the soil (infiltrate), be stored on the land surface in ponds and puddles, evaporate, or contribute to surface runoff. Most runoff is conveyed directly to nearby streams, rivers, or other water bodies ( surface water) ...
How does stormwater enter the subsurface drainage system?
Instead, the stormwater enters the subsurface drainage system by moving down through the ground.
What is the effect of stormwater pollution?
Stormwater pollution. With less vegetation and more impervious surfaces ( parking lots, roads, buildings, compacted soil ), developed areas allow less rain to infiltrate into the ground, and more runoff is generated than in the undeveloped condition.
How does soil absorb stormwater?
Most runoff is conveyed directly to nearby streams, rivers, or other water bodies ( surface water) without treatment. In natural landscapes, such as forests, soil absorbs much of the stormwater. Plants also reduce stormwater by improving infiltration, intercepting precipitation as it falls, and by taking up water through their roots.
How does stormwater affect native species?
Native species often rely on such flow regimes for spawning, juvenile development, and migration.
What is an example of urban stormwater?
An example of urban stormwater creating a sinkhole collapse is the February 25, 2002 Dishman Lane collapse in Bowling Green, Kentucky where a sinkhole suddenly dropped the road under four traveling vehicles. The nine-month repair of the Dishman Lane collapse cost a million dollars but there remains the potential for future problems.
What are the problems with unmanaged stormwater?
In developed environments, unmanaged stormwater can create two major issues: one related to the volume and timing of runoff ( flooding) and the other related to potential contaminants the water is carrying ( water pollution ).
What is the EPA's authority for stormwater?
Authorization Status for EPA's Stormwater Construction and Industrial Programs – Most states are authorized to implement the stormwater NPDES permitting program. EPA remains the permitting authority in a few states, territories, and on most land in Indian Country.
What is stormwater runoff?
Stormwater runoff is generated from rain and snowmelt events that flow over land or impervious surfaces, such as paved streets, parking lots, and building rooftops, and does not soak into the ground. The runoff picks up pollutants like trash, chemicals, oils, and dirt/sediment that can harm our rivers, streams, lakes, and coastal waters.
Why do urban areas have more stormwater?
Urban and suburban areas produce much more stormwater runoff due to the high amount of paved and hard surfaces. During periods of heavy rainfall or snowmelt, some wastewater systems are designed to occasionally overflow and discharge excess untreated sewage directly to nearby streams, rivers or other water bodies.
What is the term for the water that flows over a building?
Water from rain or snow storms, known as stormwater, instead flows over streets, parking lots and roofs and into a water body or storm drain.
Why is storm water runoff worse than normal?
Stormwater runoff is often worsened by human activities, and can contain nitrogen and phosphorus pollutants from fertilizers, pet and yard waste. Because stormwater flows over hard surfaces directly into a water body or storm drain, there is no opportunity for soil and plants or a water treatment facility to filter out pollutants.
Why does rain and snow flow over streets?
Rain and snow flow over streets, parking lots, and roofs collecting excess nutrients and pollutants before entering into a storm drain or water body. Because stormwater flows over hard surfaces directly into storm drain, there is no opportunity for soil and plants or a water treatment facility to filter out pollutants.
What are some examples of green infrastructure?
Some examples of green infrastructure techniques include rain gardens, pervious pavement, rain barrels, and green roofs. Learn more about what you can do to reduce stormwater runoff in your yard. If playback doesn't begin shortly, try restarting your device.
What is stormwater treatment?
A stormwater treatment process is the mechanism by which a stormwater treatment practice improves stormwater runoff quality, reduces runoff volume, reduces runoff peak flow, or any combination thereof. For example, a dry pond holds stormwater and releases it slowly (relative to uncontrolled conditions) to downstream receiving waters.
What is the primary treatment process for a dry pond?
The primary treatment process of a dry pond is sedimentation because most of the pollutants in stormwater that are retained by a dry pond are settled out while the stormwater runoff is held in the pond.
What is the stormwater drainage system?
All other outside drains such as the roof downpipe are connected to the stormwater drainage network. Stormwater drainage flows through outdoor drains into a pipe network and into our natural water bodies (creeks, rivers, groundwater, wetlands and the sea).
What is urban stormwater?
Urban stormwater. Stormwater, or rainwater runoff, is rainwater that runs off land and moves away from the area where it originally falls. In urban or built up areas, it is best defined as rain that runs off surfaces where water cannot penetrate such as roofs, driveways and roads. It is carried away by a series of pipes known as ...
What are the pollutants that stormwater picks up?
Pollutants include litter, nutrients such as phosphate and nitrogen, metals such as zinc, copper and lead, oil and grease from roads, garden waste, bacteria and sediments .
What is considered a water system?
The definition of waters includes the stormwater system. This means that listed pollutants cannot be placed in the stormwater system or on land where they may enter the stormwater system. Failure to comply with these obligations may result in a $300 fine, an Environment Protection Order or a prosecution.
What is the EPA responsible for?
Your legal obligations. The EPA is responsible for the control of stormwater pollution through the Environment Protection Act 1993 (The Act).
Why is seagrass dying in Adelaide?
The Adelaide Coastal Waters Study found that the loss of more than 5,000 hectares of seagrass along the Adelaide metropolitan coast could be attributed to pollution some of which is due to stormwater pollution. Key recommendations: reduce the volumes of stormwater, wastewater and industrial input.
What are the obligations of the Water Quality Policy?
The policy has general obligations which every person, business and industry must comply with as well as specific obligations for particular activities. Clauses 10 and 11 of the Water Quality Policy states that a person must not discharge pollutants listed in Schedules 2 and 3 of the Policy into any waters.
What is stormwater management?
Executive Summary. Stormwater management means to manage surface runoff. It can be applied in rural areas (e.g. to harvest precipitation water), but is essential in urban areas where run-off cannot infiltrate because the surfaces are impermeable. Traditional stormwater management was mainly to drain high peak flows away.
Why is stormwater management important?
Stormwater management is essential to prevent erosion of agricultural land and flooding of inhabited urban or rural areas. Both cases can cause severe damages and contamination of the environment if sanitation facilities are flooded. This results in high costs and notably massive suffering for the local communities.
Does runoff increase stormwater drainage?
Runoff from such surfaces has a high velocity, which adds to stormwater drainage systems. This increases peak flow and overland flow volume and decreases natural groundwater flow (as no is percolation possible) and evapotranspiration.
When did the state start regulating stormwater?
As the state’s infrastructure was built, the focus was on flooding problems, not the stormwater pollution or habitat impacts. In the 1990s, the state started regulating stormwater that comes from city and county stormwater sewer systems. To help solve the pollution problem, we established a Municipal Stormwater Permit program.
How can we get ahead of stormwater pollution?
No matter the size of a community, protecting trees and soil, allowing rain to soak into the ground, mapping your stormwater infrastructure, coordinating with neighboring communities in watershed planning and restoration activities, and doing outreach and education are great ways to get ahead of stormwater pollution.
What is the Clean Water Act?
The Clean Water Act and the Washington State Pollution Control Act required the EPA and subsequently the states to develop a permit program to manage stormwater from various sources — including stormwater from cities and counties.
When was the Puget Sound water quality plan developed?
That led us to develop the first Puget Sound Water Quality Management Plan in 1988, which included a number of stormwater action items. The Clean Water Act and the Washington State Pollution ...
What impact does this project have on America?
America’s Everglades is a one-of-a-kind network of natural resources that makes up the largest subtropical wilderness east of the Mississippi River, and the largest subtropical wilderness in the United States.
What interesting obstacles or unusual circumstances did you overcome to complete the project?
The sheer size of the project is the biggest obstacle. Constant logistical adjustments and the demand for a great number personnel/equipment are daily topics of conversation to ensure production is at its highest rate possible. Round trip for onsite hauling distances can be upwards of 20 miles per trip.
What dangers and risks did you encounter, and describe any extraordinary methods used to keep workers safe?
As previously mentioned the wildlife found in the Everglades call the surrounding areas home. Bergeron must be aware of huge reptiles, massive (and sometimes venomous) snakes, and deal with thousands of different types of insects.
How did you leverage new technologies to work faster and reduce waste?
Recycling is of great importance to this project. The excavations are creating massive amounts of materials. Rather than hauling off-site and brining in new material, much of which could contain plant matter that would be injurious to the Everglades, Bergeron has developed two (2) specific recycling plans.
