Using Treated Wastewater to Shrink Winooski River Ice Jam – Montpelier Officials Solution
The city of Montpelier took proactive measures on Monday to address an ice jam that formed on the Winooski River between the Taylor Street and Bailey Avenue bridges. According to a press release, Montpelier officials utilized treated wastewater to combat the ice jam and prevent potential flooding in the area.
Efficient Solution Implemented
Department of Public Works director, Kurt Motyka, confirmed the city’s utilization of a treated effluent ice melting system to address the ice jam. The system, which discharges treated wastewater from the city’s wastewater treatment facility into the Winooski River, effectively melts the ice and creates a channel for the river water to flow through.
Successful Execution
By 11 a.m. on Monday, the Winooski River gauge in the area indicated a water level of seven feet, just below the 11-foot action stage that would prompt preparations for potential flooding. However, by 1:15 p.m., the river had peaked at 9.63 feet before dropping to 7.24 feet half an hour later. This rapid decrease in water level was accompanied by the clearing of most of the ice through the city.
Preventative Measures
Montpelier’s emergency management team diligently monitored the river’s water levels and strategically placed barricades in critical areas surrounding the ice jam. Despite preparations, nearby roads and sidewalks remained open as the city did not need to close any due to the ice jam. Additionally, a long-reach excavator was on standby near the I-89 overpass in case of ice accumulation, but fortunately, it was not required as of 3 p.m.
Understanding Ice Jams
Ice jams, like the one experienced on the Winooski River, can occur when melting ice chunks collect and obstruct the water flow, leading to potential flooding upstream and downstream. Montpelier has faced similar challenges in the past, with a notable ice jam causing flooding and significant damage back in 1992.
In conclusion, Montpelier’s swift and efficient response to the ice jam highlights the city’s commitment to protecting its residents and infrastructure from natural hazards. Through innovative solutions like the treated effluent ice melting system, officials are able to effectively manage challenging situations and minimize the risk of flooding in the community.
