Earlier this year, the Safford, Ariz., city council asked Severn Trent Services, the company that had been operating its wastewater treatment facility for the previous six months, to report on their work. What the Council and the city’s 9,000 residents received were 146,452 reasons why the public-private partnership had been a significant benefit to the southeastern Arizona city.
Jeremy Samuels, the Severn Trent Services on-site plant manager, reported that the company’s operation of the facility will save $146,452 during the first year of operation compared to the city running the system on its own. That equals approximately $12,200 per month.
In 2007, Safford had initiated a search for an outside partner to operate the plant. According to Jay Howe, the city’s public works/utilities director, there was a need for professional maintenance and operation of the wastewater treatment plant to address the plant’s future capacity needs. He added that there had been ongoing preventive maintenance issues that had not been addressed because of inadequate city staffing. He described the plant as “the City’s most precious and important asset.”
Dana Kaas, Severn Trent Services’ vice president of operating services, noted that most small- to mid-sized municipalities don’t have the financial wherewithal or experience to match the resources of a company that specializes in water and wastewater management. “Municipalities in the United States have been outsourcing the operation of publicly owned wastewater facilities to private companies for more than 30 years,” Kaas said. “Today, it is estimated that between 2,400 and 2,600 publicly owned water and wastewater facilities are operated by private firms.”
During his presentation, Samuels went over the major objectives his company accomplished since it began running the facility. He said a number of improvements have been made, including the repair of malfunctioning equipment, the creation of a safer work environment and streamlining the plant to work as efficiently as possible. The company also made major clean-up and maintenance changes, keeping it compliant with the Arizona Department of Environmental Quality (ADEQ).
As part of their contractual agreement with the City, Severn Trent Services assumes all the plant’s liability issues. This includes the financial responsibility for paying fines if plant effluents do not meet ADEQ standards or if plant workers incur any injuries. To date, there have been no fines levied.
The Safford wastewater treatment plant processes between 850,000 to 950,000 gallons per day. According to Howe, the plant was designed to accommodate two million gallons per day and was engineered with the ability to double its capacity with minimal plant upgrades. He said that by having Severn Trent Services operate the plant, the City will be able to increase the plant’s wastewater processing capability without any plant upgrades or additions.
“With the addition of Severn Trent Service’s operational expertise, we should be able to get another 500,000, 600,000, 700,000 gallons out of the plant to increase the capacity without any new investment,” Howe said.
According to Kaas, “Cities and industrial clients rely on private partners to protect their utility investment and ensure regulatory compliance. Our professional operations personnel help improve process control while reducing administrative and operational costs. Our brief tenure at Safford demonstrates public-private partnerships do work.”
