Smithfield Upgrades Sioux Falls Wastewater Treatment System to Reduce Nitrogen Load

July 27, 2023
Pork processor invested $45 million to replace existing system and meet more stringent permit limits on nitrates and ammonia.

Smithfield Foods announced it has built a new wastewater treatment system at its pork-processing complex in Sioux Falls, S.D., replacing an existing system with state-of-the-art processes to meet stricter limits on nitrates and ammonia levels.

The $45 million operation biologically converts ammonia-nitrogen in wastewater to nitrate-nitrogen and further removes nitrate-nitrogen from wastewater, a treatment process known as denitrification, a company release stated. Denitrification will reduce the nitrogen load to the Big Sioux River by two-thirds or more.

This is the latest in improvement efforts at the Sioux Falls facility, as the company has spent $10 million over the past several years to upgrade its wastewater system.
