Water and Sewer Servicing

The Villages of Morrisburg and Iroquois are serviced by a regional water treatment plant and respective sewage treatment facilities. Sewer services are also available in the hamlet of Williamsburg.

South Dundas Water Treatment Plant

The Water Treatment Plant was operational as of June 2006 and services the Villages of Morrisburg and Iroquois. It is designed to provide capacity for a twenty year period with a capacity of over 9,000 m3 per day.

The facility uses a state of the art membrane filtration system as well as granular activated carbon contractors to eliminate any odours and taste.

Waste Water Treatment

Both of South Dundas’ Waste Water Treatment Plants are designed to serve the community for 50 years with capacity to treat additional affluent.

An 18 Million dollar project to upgrade the Iroquois Waste Water Treatment Plant was completed in July 2014. Improvements included the addition of a secondary treatment process to further reduce the impact of wastewater on the local environment as well as increase the plant’s overall capacity, efficiency and reliability.

The Morrisburg Waste Water Treatment Plant came into service in 2009 and a lagoon system serves the Village of Williamsburg.

Broadband Services

The Municipality was one of the first ever Canadian municipalities to have its village businesses fully connected by fibre optics.

Surrounding areas are serviced by wireless or satellite service with speeds of up to 10 Mbps. 10 Mbps is sufficient bandwidth to browse the internet, share large files, stream video and do video conferencing.
