TransAqua's Sewage Management Dilemma: Balancing Costs and Smell Concerns
New Brunswick's wastewater utility, TransAqua, is grappling with a complex issue that affects both the environment and residents' quality of life. The story revolves around the management of sewage byproduct, specifically the challenge of finding cost-effective alternatives to composting biosolids while addressing persistent smell complaints.
The Smell Dilemma in Moncton
Moncton, a city in New Brunswick, has been grappling with a persistent issue: the foul smell emanating from the composting facility of TransAqua's wastewater utility. This problem has been a source of concern for residents in the city's north end, leading to multiple complaints over the years. The situation escalated to the point where the Moncton council passed a motion in February 2024, demanding TransAqua take action to enclose the facility in a building or relocate it outside the city.
Exploring Costly Alternatives
TransAqua's general manager, Kevin Rice, revealed that the utility is currently analyzing various options to address the smell issue and the associated costs. These options, estimated to cost around $40 million, are crucial to avoid a 'rate shock' for residents. The utility aims to ensure that any changes in rates are well-communicated and planned, allowing for appropriate funding and mitigation strategies.
Cost-Effective Solutions
Two primary methods are under consideration. The first involves mixing lime with biosolids, which could then be utilized for agricultural purposes, with a preliminary estimate of $34 million. The second method, anaerobic digestion, utilizes microorganisms to break down the material, producing gas that can be burned. This process offers the potential to recover costs through electricity or renewable natural gas generation.
Impact Beyond Moncton
TransAqua's decision has broader implications. In 2022, the utility acquired a second composting site north of Moncton in the municipality of Five Rivers. This move has reduced smell complaints in Moncton but sparked concerns in Five Rivers. The utility is now faced with the challenge of managing waste and biosolids while balancing the needs of both locations.
Future Challenges and Population Growth
With projected population growth, both composting sites are expected to reach capacity by 2037. This highlights the urgency of finding sustainable solutions. The utility must develop a risk mitigation plan, considering the potential impact on residents and the environment.
Community and Political Response
Moncton Coun. Bryan Butler, representing the city's north end, has been vocal about addressing the smell issue. He acknowledges the utility's efforts but expresses uncertainty about the chosen solution. The utility's board will receive details next month regarding the impact on wastewater rates, and discussions with the federal government about potential funding are underway.
