In this week's water and wastewater news, two men working at a lift station in Mississippi are overcome by methane gas, and 60 million gallons of untreated wastewater per day are spilling into the Missouri River
Two workers were killed after being overcome by methane gas in a wastewater lift station in Petal, Mississippi.
The city had contracted with a company to do work at the lift station, and the city’s crew was on scene for most of the day. Mayor Hal Marx told USA Today, “They told our crew they could leave and they were finishing up.”
Of the three men working for the contractor, two were discovered unconscious in the lift station. First responders pulled the men out from a depth of 15 feet, but attempts to resuscitate them failed.

Missouri River Soaking Up 60 Million Gallons of Wastewater Per Day Due to Storm
Around 60 million gallons per day of untreated wastewater are spilling into the Missouri River in Omaha, Nebraska, thanks to a power outage.
Storm damage to the electrical infrastructure near the Papillion Creek Water Resource Recovery Facility is causing the problem.
The Omaha Public Power District says it’s not sure when power will be restored to the plant, but in the meantime, the city’s public works department is telling citizens not to wade, swim or come in contact with the Missouri River miles downstream from the plant.

Unauthorized Hydrant Opening Causes 140,000-Gallon Wastewater Spill
Officials in Kalamazoo, Michigan, say an unauthorized person opened a fire hydrant to cool off during a recent heat wave, causing more than 140,000 gallons of wastewater to spill into the streets.
The sewer was plugged to prevent the release of wastewater during a nearby construction project.
City officials say up to 110 gallons of sewage were likely released along with the wastewater.
The city fixed the storm sewer and got the wastewater cleaned up later the same evening.

Mississippi City Pays Fine for Excess Cyanide
The city of Forest, Mississippi, has agreed to pay a fine of $2,000 to the state’s Department of Environmental Quality for discharging cyanide in excess of the legal limit at its wastewater treatment plant.
A regulator for the DEQ says Forest had violations in November 2014 and February 2015. Forest won’t be required to pay $5,500 of the total $7,500 fine if it meets cyanide regulations for three straight months.
The city informed the regulator that it has found the source of the problem and addressed it.
