Milk Disposal Estimator

Even if disposing milk into a wastewater processing lagoon is permitted, dumping too much milk in a day could impair lagoon functions, causing odor and water quality problems. Small-batch, multi-day discharge may lower these risks. This tool estimates the milk treatment capacity of your lagoon, and recommends the number of days it takes for the lagoon to accept all the milk.

Odors must be minimized?
Is this a lagoon processing diluted manure (approximately 2% solids)? 
Does the lagoon have cover or mechanical aeration? 
Your county VSLR (lb/ft^3/d) :                   
Number of calf:                                         
Number of heifer:                                         
Number of lactating cow:     ‌‌                        
Number of dry cow:                                    
Total daily volatile solids loading( lb/d):    
Total milk volume (gal) :                               
Operating volume (ft^3)** :                         

Minimum days required to discharge a batch of milk into a lagoon:                    

*If your county is not on the list, please enter the volatile solids loading rate (VSLR) for your county in the VSLR box (you can find the VSLR for your county here.)
**Operating volume is the sum of minimum treatment volume and waste volume.

Disclaimer: This calculator is intended to provide a general guide of minimum days required to discharge a batch of milk into a lagoon. It does not account for all variable factors, conditions, or regulations/requirements. It is the user’s responsibility to use your best judgment and to adhere to application guidelines outlined in your plan/permit according to regulatory agencies. The Texas Animal Manure Management team and the AgriLife Extension assume no responsibility for inappropriate milk/manure application. Proper application is ultimately your responsibility.
