It’s three in the morning — low-flow time.
You’re at the Billings Wastewater Reclamation Facility, a 40 mgd (design) plant undergoing a major upgrade for nutrient removal on the fly. You and your team are about to take the existing clarifiers down, open a slide gate and transfer flow to a new basin.
