Storm Water BMP: Understanding the Wet Pond/Retention Basin

Retention is a stormwater BMP that takes advantage of the conventional storm water basin. This collects water from the surrounding area, preventing flooding, erosion, and other types of property damage. What makes this storm water BMP unique is the ability to slowly release water from the retention area – or storm water basin – at a controlled rate. Think of this as a miniature dam system that works to prevent streams and rivers from getting overwhelmed with floodwaters and eroded.

A retention basin is a storm water BMP that takes advantage of a higher orifice, which means that it will retain a permanent pool of water throughout the year. One of the benefits of retention basins over detention basins is the treatment that can be done to water. Using retention basins for stormwater BMP provides the opportunity to reduce pollutants in the water that could damage surrounding streams and areas.

Light maintenance is required to ensure that this storm water BMP works properly. For instance, it’s crucial to ensure that the orifice isn’t blocked or clogged with debris, as this could hinder water flow out of the basin.

However, while similar to detention, it’s important to note that retention basins are a storm water BMP that result in a permanent pool of water. Don’t worry – this isn’t like a random body of floodwater. Think of it as a man-made pond. Detention basins result in the waters eventually being empty and dried in-between each storm. An orifice is used to determine the water level, and water will drain out in a detention system so that it can refill the next time a line of thunderstorms come in.

Storage and Detention Leads as Stormwater BMPs

Underground stormwater detention systems that allow detention are considered one of the most effective stormwater BMP systems available to control the flow of stormwater. Though the systems can be found beneath streets, parks, and parking lots, these stormwater BMPs can be used anywhere in residential and commercial areas alike. When it comes to stormwater BMPs, there are two considerations you want to keep in mind:

  • Cost efficiency, as the cost of managing stormwater and the installation of the BMPs themselves can become overwhelming.
  • Environmental-friendliness, as the system should maintain the highest pollutant removal rate to ensure safety for the local and regional ecology.

StormChamber by HydroLogic Solutions offers stormwater BMPs that combine both of these incredible elements into a single system. One of the most effective uses of StormChamber is utilizing it as a tool against localized flooding. By collecting excess water in a basin and regulating its release into nearby stream systems, you can ensure that downstream areas are safe from unnecessary flooding or erosion. When it comes to using a retention basin, the two options available are retention and detention.

With a detention basin, the orifice level is kept low at the bottom of the basin. This ensures that the area is emptied and dried before the next storm system comes through the area. This is also why it’s referred to as a dry basin. This stormwater BMP is effective and important for slowing floodwater runoff.

StormChamber was designed by engineers, ecologists, and biologists to ensure maximum efficiency and effectiveness. To ensure that the stormwater BMPs work at the highest removal rate possible, StormChamber incorporates an open bottom, arch-shaped, HDPE infiltration chamber that allows it to work in both permeable and non-permeable soils. These stormwater BMPs boast the ability to manage detention, conveyance, and retention on all subsurface.

Used in congruence with SedimenTrap, StormChamber ensures that the water regulated is cleansed of floodwater pollutants that could potentially harm the local ecology as it’s pumped back into surrounding streams, wetlands, and lakes.

The benefits of using StormChamber for detention include:

  • Cost efficiency, effectiveness, and ease of installation
  • The latest technology and equipment available in stormwater BMPs that achieve low impact development, LEED, and zero discharge standards
  • Ability to replenish groundwater supplies
  • Can be used with SedimenTrap to achieve higher pollutant removal rates
  • And much more!
Residential Water Reuse


  • “Because we have installed several StormChamber systems, a lot of engineers have asked for advice on competing plastic chambers. We have always recommended the StormChambers. They far exceed the competition on cost and ease and speed of installation.”

    Dean Clark General Manager, SECO, LLC, Chelton, WA
  • “Much less expensive and much quicker and easier to install than the 64″ pipe originally speced for the project.”

    Joe Szabo Owner, J&R underground contractors, Milan, MI
  • “Significantly faster and easier to install than pipe. Significantly less staging room needed and a lot fewer trucks to receive and unload.” (The equivalent of 213 LF of pipe nest on one pallet, 1,913 LF on one truck.)

    Bob Dawson Owner, Dawson Company, Woodbridge, VA
  • “We have installed several StormChamber systems because we find them to be a lot less expensive and quicker to install than the competing systems and we can install them in two layers on very confined sites.”

    Ed Shaw Shaw Construction, Reno, NV
  • “We were surprised by the ease of use of the system and greatly appreciated support provided. We are already looking forward to building our next StormChamber project!”

    “I also like that it can be cleaned by air vacuuming via inspection /cleanout ports instead of using water. Anytime you have to clean something with water, then you have to have a truck that collects the water and the sediments in it. Depending on where you can dump that, it can get much more costly as opposed to going out with a vacuum truck.”

    Steve Pandish Director of Water Resources for the engineering firm of William H. Gordon Associates in Chantilly, Virginia

    “The choice of StormChambers met the design requirements for strength in such a way that the chambers could be stacked three deep with 30 feet of cover, if needed. Strong enough to sustain the impact of 18-wheelers loaded with steel. They also were 30 percent more cost-effective than other options.”

    Dr. Paul Mankiewicz hydrologist and consultant to the City of New York on storm water and related issues and executive director of the not-for-profit Gaia Institute in the Bronx, NY
  • Double-stacked system in Tukwilla, WA

    “It was easy. There were no difficulties once the owner decided on the StormChamber system. The project is holding up to heavy traffic, pump tracks, and cranes.”

    Tom Radice Abbot Construction
  • Charles-Lemoyne Hospital, Greenfield Park, Quebec

    "We were amazed by the simplicity of this system and have appreciated the support from the Soleno team during the entire project. We are already looking forward to designing another project using the StormChamber!"
