Learn more about retention ponds below.
I will explain how the pond works and the installation process. We will learn about the types of retention ponds and their unique benefits and disadvantages.
A retention basin, sometimes called a wet pond. The basin or stormwater management pond, is artificial in design. Vegetation surrounds the perimeter. Some ponds can contain a permanent pool of water in its design.
Retention ponds are constructed by excavating a land area to form a depression. This makes for the land area capable of holding and retaining stormwater. Often times the ponds will have a synthetic or clay soil liner for water retention. Retention ponds can have a series of outfall drains, pipes or spill ways for stormwater management.
As you learn more about retention ponds, you will better understand their importance to the Environment.
In stormwater runoff, there exists everyday pollutants from roadway, parking lots and sidewalk services. Through stormwater management, water is directed to the ponds.These soils are designed to support unique vegetation and to absorb hard surface pollutants. Retention ponds are a way to direct pollutants to a location for pollution control. This control allows for the protection of our natural resources.
The retention pond can eliminate risks associated with a large volume of stormwater run-off. With large capacity drains, stormwater is directed to the ponds. Here, water can be released back into the environment through pipes, spill ways or absorption. The release of the stormwater is determined by plans designed by Engineers. Retention pond design will determine the rate of water release as per design plans.
The vegetation inside and around the perimeter of the pond carries out filtration on the stormwater entering into the pond.
There are two types of retention, we have a wet and dry retention pond.
Also called a wet pond or simply a bio retention pond, wet retention ponds characteristically contain a permanent pool of water. They have a large depression that holds water all year round. The network of underground pipes installed direct stormwater to the pond. Any stormwater entering into the pond will replace the previous pool of water.
Dry retention ponds are best suited for areas where there are ten or more acres of available land area.
Every retention pond has a general water treatment mechanism. The retention time causes the stormwater to settle inside the pond, thereby allowing for settling and sedimentation of pollutants present in the water.
These soils are present in the pond and of design specific. Often these soils are called bioretention soils and provide for water purification. The soils cleanse the stormwater runoff through filtration.
Vegetation ensures ground stability. It is important to select a hardy vegetation of year round growth.
These soil mixes provide filtration and water treatment to stormwater. The soil mix design presents several benefits to a retention pond with the removal of impurities and contaminants. This removal process improves the quality of stormwater and provides for aquatic plant growth in the pond.
Increased community development demands for permanent structures designed to hold water flow. These structures are called retention ponds.
Retention ponds are usually 3 – 9 feet deep.
Retention ponds are known to have fish.
Retention pond water can become contaminated with dangerous bacteria.
Make sure your pond is far enough away to avoid damage to the existing home foundation.
Retention ponds maintain water throughout the year. Detention ponds hold water for short periods of time.
Maintain the earthen berm and surrounding vegetation. Reduce overgrowth and trees from the area.
Organic decay and water runoff contaminants can effect the quality of the pond water.
The bioretention pond removes contaminants and sediments from stormwater runoff. This is done with the bio mix soils and vegetation.
Stormwater ponds are bodies of water where stormwater runoff is collected.
There is no federal law that requires fencing around a pond. Check with your city, county and or state for code compliance.
Recommendations suggest a minimum of 2 times a year.

Catch basin installation might range from $2,500 to $5,000.
Severe rainfall can overwhelm retention ponds.
Bio mix soils are a rich blend of sand, silt, clay, and organic matter in varying proportions, of which sand makes up the larger part. The purpose of the sand is to provide proper drainage and prevent the overflow of surface run-off.
Maintaining your retention pond ensures it functions effectively. Regularly check for sediment buildup and remove debris from the water. Trim overgrown vegetation around the pond to prevent blockages. Inspect the pond liner and repair any damage to prevent leaks. Ensure the outfall drains and pipes are clear for proper stormwater management. Keeping up with these tasks helps maintain water quality and functionality. For ongoing maintenance, consider scheduling professional inspections.
Retention ponds serve as critical components of urban and suburban infrastructure. Their primary responsibility is to collect rainwater runoff from impervious surfaces, such as roads, parking lots, and rooftops, to prevent drainage systems from becoming overwhelmed.
Retention ponds are also an important BMP in residential stormwater management used to collect sediment runoff so that all pollutants can be treated before water is discharged back into public systems.
Understanding this, conducting regular maintenance of your retention ponds is an essential step to maintaining local infrastructure and protecting the environment.
This guide will provide an overview of retention pond maintenance, including how it works, why it’s essential, and why you should invest in regular inspections.
Retention ponds are man-made structures designed to collect excess stormwater during rainfall events. They are constructed as deep ponds that allow for a few feet of standing surface water and sediment to collect in a storage unit at the bottom of the pond.
Most are surrounded by steep banks with rocks, vegetation, or riparians designed to filter out sediment.
Aside from its primary responsibility of storing rainwater, retention ponds allow for the gradual discharge of rainwater–free of sediment–to protect rivers and streams from excess turbidity.
Having a functioning retention pond benefits local residents and construction companies in multiple ways:
While they may look like permanent structures that require little maintenance, this is actually a popular misconception.
Retention pond maintenance is an essential component of protecting your local environment both during and after construction activity has ceased.
Some essential maintenance tasks will include:
Evidence of poor maintenance will soon manifest in several different ways, including algae blooms, excessive plant growth, poor water drainage, and a foul odor. These symptoms could lead to reduced water quality and downstream pollution, which you may be liable for.
Proactive retention pond management can save you lots of money and stress down the line on expensive repairs or filtration systems. Nevertheless, some challenges exist for companies and residents, such as invasive plant species that grow out of control, expensive structural issues, and sediment buildup that becomes difficult to keep up with.
Seasonal weather, such as snow, excessive foliage, and even summer pests, can also bring a whole new set of challenges to maintenance.
Therefore, hiring a company to assist with retention pond maintenance can often be a cost-effective measure to save you money down the line.
Everybody indeed wants to get the cheapest deal possible, but forgoing professional inspection and service for DIY solutions may end up costing you in the long run.
A professional retention pond inspection will encompass several areas outside of your expertise, including:
For thorough and efficient professional retention pond maintenance and inspection, trust the experts at Valor Environmental. We offer various erosion control services designed to protect local infrastructure and ensure construction projects run smoothly.
Whether you own a residential or commercial retention pond, be sure to give us a call for all maintenance and construction needs.
Maintenance frequency varies based on factors like pond size, location, and surrounding land use. Generally, routine inspections and minor maintenance should occur quarterly, while major activities like dredging may be needed every 5-10 years.
While some tasks can be DIY, professional maintenance ensures comprehensive assessments and compliance with regulations.
Biodiversity promotes ecosystem health, resilience, and balance, contributing to a thriving pond environment.
Retention ponds collect stormwater runoff, preventing flooding and erosion while improving water quality through sediment settling.
