Sudbury Waste Water Treatment Facilities

There are 9 Waste Water Treatment Facilities (WWTF), 3 sewage lagoons and several lift stations located within the Vermilion River Watershed?  5 of these WWTF are upstream of the public water intake facility just below Cascade Falls, on the Vermilion River.   This public water intake services 13,000 people in Lively, Walden, Copper Cliff and Whitefish.

The City of Sudbury was listed in the 2009 EcoJustice Report, “Flushing Out the Truth – Sewage Dumping in Ontario”, as the 4th highest in Ontario for releasing untreated and under-treated sewage into the environment.   The map below shows all the WWTF & Sewage Lagoons located within the Vermilion River Watershed.

A Public Forum was held in the Fall of 2009, with the purpose of raising an awareness of the challenges, and to look for solutions.   Since then, the City of Sudbury WWT have worked diligently to minimize the number of by-passes, and has introduced a new by-law to make it illegal for eves trough downspouts to be hooked into the public sewer system.  The City is also conducting smoke testing to find all those illegal hook-ups.   The problem is aggravated when heavy rain events occur, and these illegal hook-ups cause sewers to be overwhelmed.  To avoid back-ups into residence basements, the effluent must be bypassed into the environment.  It will take time to find all the hook-ups, however, the City is continuing to make progress in improving the system.

Rainy days are anything but cleansing for Ontario’s waterways and Great Lakes — these fresh water resources double as sewage dumps when municipal systems are overburdened.  For more information on this topic, you can visit the EcoJustice.

National Sewage Report Card III

Ecojustice’s work on sewage has brought national attention to the issue of sewage dumping and poor treatment, most notably our leading series of national sewage report cards.  For more information on this topic, you can visit EcoJustice.

The Lower Vermilion Source Water Quality Program is a 3 year study to characterize the lower Vermilion River to identify all negative inputs and outputs affecting water quality, and to ultimately recommend a course of action to protect and restore water quality on the Vermilion River system.
