Stormwater Retention Ponds
Stormwater ponds are bodies of water in commercial and residential developments that collect and store stormwater runoff. These ponds improve water quality and control water quantity. Stormwater ponds reduce pollution and prevent downstream flooding. Stormwater ponds can be attractive or can become eyesores depending on how they are managed.
The National Pollutant Discharge Elimination System (NPDES) Stormwater Program regulates stormwater discharges from three potential sources: municipal separate storm sewer systems, construction activities, and industrial activities. Most stormwater discharges are considered point sources, and operators of these sources may be required to receive an NPDES permit before they can discharge. This permitting mechanism is designed to prevent stormwater runoff from washing harmful pollutants into local surface waters such as streams, rivers, lakes or coastal waters.
Algae are present on vegetation, in the air, soil and water. Their microscopic spores are continuously introduced by wind, dust storms, rain showers, etc. into these retention ponds. Algae blooms can increase pH alkalinity to the point that discharge permit requirements are not met.
Ultrasonic units have been used effectively to aid in the control of algae blooms in stormwater ponds. The 24 V solar powered system uses renewable energy to maintain an eco-friendly, sustainable treatment program. For a free consultation, call 413-531-0393.
