Drinking Water & Wastewater Effluent Monitoring

Drinking Water

Protecting water at its source is a crucial first step in Muskoka’s approach to delivering safe drinking water.  When you turn on your tap, you can be confident that your drinking water is among the best protected in the world.

Monitoring Drinking Water

The District is fortunate to have clean lakes and rivers to supply drinking water to thousands of residents. Across Muskoka, residents get their drinking water from a range of sources including wells, seasonal lake-intake pipes or the District's municipal water treatment processes. 

For municipal treated water, several processes occur before the water comes out of your tap- and -it all starts with water monitoring. 

In Muskoka, water is drawn into water treatment plants from intake pipes from our local lakes or rivers. This ‘raw’ water is monitored daily for turbidity, pH, temperature, and dissolved oxygen levels to ensure that the treatment process is set appropriately. Water is also tested for microcystins, the toxin produced by blue-green algae (cyanobacteria), at the intake site four to five times a month between May and October.


Wastewater Effluent Monitoring

Wastewater treatment operators are certainly doing their part in making sure Muskoka’s waters remain as clean as possible. 

Some Muskoka residents are connected to the District’s sanitary sewer system. When toilets are flushed or sinks are drained, this water eventually enters local lakes and rivers. Before this happens, the wastewater undergoes several treatment processes removing contaminants such as phosphorus and nitrogen. Without proper treatment, these contaminants could significantly impact water quality and make it unsuitable for swimming, fishing, and other recreational activities. 

For that reason, the Ministry of the Environment, Conservation and Parks (MECP) sets phosphorus and nitrogen limits in wastewater effluent. The District is proud to be continuously under the permitted limits.  

This management of phosphorus and nitrogen in wastewater effluent means that lake water quality in the Muskoka watershed is protected and healthy to swim in, fish, play and enjoy.
