What is stormwater management pond?
A stormwater management pond is an engineered structure intended to collect rainfall and surface runoff (stormwater) from your subdivision. Stormwater enters a series of catch basins and storm sewers, and then drains to a stormwater management pond.
How do stormwater management ponds work?
Stormwater ponds collect all of the stormwater runoff from neighbourhood streets. This flowing water can take all types of contaminants along with it, making the water quality conditions unknown. In winter, moving water and fluctuating weather conditions lead to unknown, unpredictable and dangerous ice conditions.
How deep are stormwater management ponds?
Typically these ponds are designed to have a water depth of three metres, which can rise quickly after storms.
How is stormwater managed on a construction site?
These include stormwater management products, including drain, curb and gutter guards, pipe socks, concrete filters, fuel mops, sand- and/or gravel-bags, dewatering products, sediment traps and bunds/spill containment systems (ramps, humps or channels made from impervious materials).
Can you swim in stormwater pond?
Stormwater ponds are built for drainage and esthetic purposes, she said, but no one should go in their waters for any reason — not to swim, boat, or float. These ponds differ from designated swimming ponds and lakes, because drainage ponds can have steep dropoffs and sludge at the bottom that you can sink into.
What is the purpose of stormwater?
Stormwater is rainwater or melted snow that runs off streets, lawns and other sites. When stormwater is absorbed into soil, it is filtered and ultimately replenishes aquifers or flows into streams and rivers.
Why do subdivisions have retention ponds?
While it may look like a regular water feature, a retention pond serves a much greater purpose. Growing communities are at increased risk of flooding and erosion damage from excess stormwater runoff. Retention ponds are permanent structures designed to hold water flow for a short period of time, similar to a dam.
How does construction affect water quality?
Sediment pollution from construction sites contaminates drinking water, impacts recreational waters, diminishes commercial fisheries and increases the risk of flood damage. Dirty runoff from construction sites can also carry other pollutants into waterways.
What are the control measures for stormwater runoff?
Following are some of the green infrastructure and LID practices EPA uses to reduce stormwater runoff and pollution:
- Green Roofs.
- Rain Barrels and Cisterns.
- Permeable Pavements.
- Bioretention Areas.
- Vegetated Swales/Dry Swales.
- Curb and Gutter Elimination.
- Vegetated Filter Strips.
- Sand and Organic Filters.
Are ponds a wetland?
Common names for wetlands include marshes, estuaries, mangroves, mudflats, mires, ponds, fens, swamps, deltas, coral reefs, billabongs, lagoons, shallow seas, bogs, lakes, and floodplains, to name just a few!
What are the dangers of stormwater retention ponds?
These ponds are significantly helpful in the area of stormwater management and flood control. However, these ponds can also pose a significant risk to public health, safety and welfare. A main safety concern regarding these ponds is that children are extremely attracted to them and can risk drowning or other water-related personal injures.
What is the purpose of stormwater ponds?
The purpose of stormwater ponds is to control excess stormwater runoff and improve water quality to nearby streams. When enhanced with plantings, they can be attractive and increase residential property value. They can provide habitat to attract turtles, frogs, butterflies and birds that also help improve our own quality of life.
What is storm water retention pond dredging?
What is Storm Water Retention Pond Dredging? Retention ponds are manmade ponds used to collect and clean storm water so surrounding neighborhoods don’t flood. Urban areas are especially at risk for flooding because the impervious surfaces of asphalt and concrete increase the flow rate of storm water.
What is storm water control plan?
A Stormwater Pollution Control Plan is required to ensure that Best Management Practices are used during construction and over the life of a project to minimize soil erosion and sedimentation that could result in storm water pollution.
