Why do effluent ponds get crusty?

Wondering why the effluent ponds on your farm are getting crusty?


A crust on an effluent pond consists of undigested organic matter that is lighter than the liquid moving through the effluent system. Since it is lighter, the organic matter naturally floats to the surface to form a crust.

Crusted Pond

Effluent crust is particularly a problem during the summer. The organic matter can dry out quickly, leaving weeds to germinate and grow to form a thicker crust. In the past, the traditional method was to manage the crust by allowing the biology in the pond to take care of itself. To some extent this method worked, but the only effective method of managing crust in a pond is to thoroughly stir the pond with the appropriate pond stirrer.

Pond crust can be reduced with a better stone trap system or a solid separator method, but we do not recommend this approach. A solid separator method can initially remove the crust away from the pond, but it will create more work later on, leading to less efficient operations.

Stone Trap

The best method for managing effluent pond crust is to allow the effluent to enter the pond and to then stir the pond with an effective pond stirrer. At Nevada, our pond stirrers operate with high-quality performance that is reliable and safe for farmers to use with ease. With easy angle adjustment for both electric pond stirrers and PTO pond stirrers, you can stir effluent crust with minimal hassle while improving operations and saving time.
