Meadow Rock Dairy Case Study: Lagoon Pumping Time Cut 52.5% in 45 Days with AWT Lagoon Bacteria

At Meadow Rock Dairy, weekly Animal Waste Treat digested a 3 to 4 ft crust, restored 95% open water, and cut lagoon pumping from 80 to 38 hours in 45 days.

The problem

Meadow Rock Dairy Farm needed to restore function to a 67,500 yd³ waste lagoon that had developed a 3 to 4 foot thick manure mat and crust across the surface, along with a persistent putrid odor. The buildup made routine pumping slow and costly and cut into storage capacity. The goal was to reduce solids, restore open water, eliminate odor, and shorten the pumping time needed to draw irrigation water from the lagoon. The trial tested whether Animal Waste Treat (AWT), a spore-forming Bacillus blend that degrades fats, proteins, and fibrous solids in livestock and dairy waste, could deliver measurable improvement within 45 days. AWT was applied weekly.

Before, during, and after

Before treatment: a 3 to 4 foot manure mat and crust covered the surface, odor was constant, and drawing irrigation water took 80 hours per cycle.
Before
Before treatment: a 3 to 4 foot manure mat and crust covered the surface, odor was constant, and drawing irrigation water took 80 hours per cycle.
After 30 days of weekly AWT, the lagoon reached 60 to 70% open water and odor had dropped sharply. Pumping fell from 80 hours to 55 hours per cycle, a 31% reduction in under half the trial window, a sign that AWT was digesting the surface crust and improving lagoon hydraulics well before day 45.

After 30 days of weekly AWT, the lagoon reached 60 to 70% open water and odor had dropped sharply. Pumping fell from 80 hours to 55 hours per cycle, a 31% reduction in under half the trial window, a sign that AWT was digesting the surface crust and improving lagoon hydraulics well before day 45.
After 45 days of weekly AWT, pumping dropped to 38 hours per cycle, 42 fewer hours and 52.5% less time per irrigation event than baseline. The lagoon reached 95% open water, odor was gone, and the scum layer, bottom sludge, and total suspended solids all improved substantially.
