Urethane Stator

Moyno’s new urethane stators increase pump life for wastewater treatment plant

The City of Hamilton, Ontario’s Wastewater Treatment Plants collect both sanitary and combined sewage (wastewater). The collection system services not only the City of Hamilton, but also the surrounding areas including the towns of Dundas, Ancaster, Water Down, Glanbrook Township, and the former city of Stoney Creek. The City of Hamilton’s Woodward Avenue Wastewater Treatment Plant began operations in 1964 and today averages 108 million gallons (409 million liters) per day with a peak capacity of over 158 million gallons (600 million liters) per day.

The City of Hamilton Wastewater Treatment Plants have continuously battled with the abrasive quality of the processed water. The abrasive sludge has caused shortened life for their nitrile stators and became an issue due to the cost of continuous maintenance and replacement stators.


Moyno partnered with the City of Hamilton to test the new Urethane stators in their abrasive municipal sludge application. The successful operation of the City of Hamilton’s wastewater treatment is vital to the surrounding environment, especially the Hamilton Harbor and its ecosystem. The Windermere Basin is located in the east end of Hamilton Harbour, at the mouth of Red Hill Creek. Over the years, its ecosystem had been significantly altered and impacted by human activities.

This project transformed the degraded body of water, with limited diversity, into a healthy, diverse Great Lakes coastal wetland. The improvement plan involved creating a wetland and constructing hydraulic controls, a fish way, a power building, islands, containment dikes, and local landscaping.

Overall, this project helped create a new aquatic habitat not commonly seen on this scale. The environmental benefits will also support increased populations of healthier aquatic and bird species that live in the cleaned up Windermere basin.

The basin also enhances the landscape in an industrialized zone located in Hamilton’s east end and will provide social benefits to city residents.

“This program of work represents a large-scale project that we could not have completed without the generous support from our federal and provincial partners,” says Hamilton Mayor Bob Bratina. The mayor went on to note how the Windermere Basin project created a unique wetland area, vastly improving the habitat for local fish and wildlife. “All of these efforts contribute to our local goals for the remediation of Hamilton Harbour,” Mayor Bratina adds.


Representatives from the governments of Canada and Ontario, and the City of Hamilton have affirmed their commitment to improving the public health and quality of life.
“Investing in local infrastructure renewal will build stronger communities and improve Hamilton residents’ daily lives,” says the Honorable Jeff Leal, Minister of Rural Affairs for Ontario. “The Wastewater Treatment and Windermere Basin projects demonstrate the Ontario government’s ongoing commitment to work with our federal and municipal partners to address the province’s infrastructure priorities.”

The project will enhance the quality of life for visitors and residents in the City of Hamilton and contribute to public health improvements and the protection of the environment. The positive results of this work will also help remove Hamilton Harbor from the Area of Concern list under the Canada – U.S. Great Lakes Water Quality Agreement.


The success of the Moyno urethane stator far exceeded their expectations. The City of Hamilton has ordered five additional new urethane replacement stators for their pumps after the first urethane stator outlasted the nitrile stator by more than ten times and continued to run without failure. As the City of Hamilton continues to expand, the Moyno urethane stator will lower maintenance costs and significantly reduce down time for the city of Hamilton’s wastewater treatment operation.

“The improved wastewater treatment system and Windermere basin are major achievements,” says the Honorable Peter Kent, Minister of Environment. “Our government is proud to have invested in cleaning efforts that will help the environment, improve quality of life for Hamilton residents and that has created jobs.”

Improvements and innovations like these are key to “Building Together,” the province of Ontario’s long-term plan to repair, rebuild, and renew the province’s infrastructure. Since 2003, Ontario has invested approximately $85 billion in infrastructure. Building modern, efficient infrastructure has created or preserved close to 100,000 jobs each year, on average, making Ontario’s economy more productive and improving quality of life, now and in the future.
