IEC’s baffles are designed to improve water and wastewater quality by eliminating short-circuiting and increasing detention time in ponds, lagoons, and tanks. Baffles are commonly used in municipal water and wastewater treatment facilities, industrial processes, and stormwater management systems. As experts in the field, we will recommend the correct design from the best geomembrane and materials for your specific application.

Types of Baffles

We offer a wide range of floating baffles to suit your specific needs. These baffles come in various materials, such as XR-5, HDPE and a variety of other materials. We also offer potable water grade materials for water treatment and drinking water applications that require the NSF / ANSI 61 standards.
  • Floating Baffles
  • Clearwell baffles
  • Partial and full depth Pond and Tank baffles
Each type of baffle serves a specific purpose, and our knowledgeable team can help you determine which one is best suited for your application.


Baffles direct the flow of water and wastewater, typically in a serpentine pattern.  They enhance the efficiency of water and wastewater treatment facilities by preventing short-circuiting and improving effluent quality for BOD, ammonia and TSS. They are a cost-effective solution to managing flow and ensuring optimal treatment in both industrial and municipal settings.  Our baffles are being successfully used by a wide range of clients and industries including municipal water and wastewater treatment plants, stormwater retention ponds, industrial process water, mining, refineries, and anaerobic and aerobic systems.


IEC is committed to making the installation process as smooth as possible for our clients. From site assessment and baffle selection to post-installation inspection and adjustments, we ensure that your water or wastewater baffle system meets all of the specifications and requirements. Whether you need a floating baffle curtain for your pond, lagoon, or tank, our expert technicians will ensure proper installation and optimal performance.

Frequently Asked Questions

A: Installing baffles in a wastewater treatment pond, lagoon or tank, helps improve effluent quality by controlling circulation, reducing debris flow, and enhancing the efficiency of the treatment processes. Baffles reduce the total suspended solids (TSS), by increasing hydraulic retention time (HRT), and biological oxygen demand (BOD) in the water, ultimately leading to cleaner effluent.
A: Tension members and ballast chains are essential components. Tension members provide strength and stability, ensuring that the baffles maintain their shape and position, while ballast chains help anchor the baffles to the bottom of the treatment area, keeping them in place even in areas with high water flow or current.
A: Yes, our baffles are designed to withstand a range of temperatures and weather conditions, making them suitable for use in colder climates like Minnesota and Canada. Our high-quality materials and construction ensure durability and effectiveness in various environments.
A: The size and type needed for your treatment area will depend on factors such as the area and configuration of your basin, the amount of water or wastewater flow, and the specific quality issues you’re facing. Our knowledgeable team at IEC can help you assess your needs and recommend the most suitable water or wastewater baffle options for your situation.
A: Baffles help settle solids and sediment from the water and control turbidity within the treatment area.
A: Absolutely! Our baffles are designed to be versatile and can be used in various applications, including reservoirs and other large-scale water treatment areas. Our custom sizing and construction options ensure that our baffles can meet the unique requirements of your specific project.
A: At IEC, we use a variety of high-quality materials in the construction of our baffles. Most commonly used are raw materials such as stainless steel, XR-5, and HDPE, all suitable for potable water scenarios requiring NSF / ANSI 61. The specific material used depends on the type of water, the baffles intended application, baffle length and depth.
A: Regular maintenance is generally not needed. The materials used are UV resistant for longevity and long-term effectiveness.
A: Yes, we offer custom sizing options for all of our baffles to ensure that they perfectly fit your treatment area and meet your specific needs. Simply contact IEC with your requirements, and we will be happy to provide a quote for a custom-sized water baffle.
