Water Quality in Oshawa, Ontario

The municipal drinking water in the city of Oshawa is treated according to Canadian standards, but the tap water is still too hard for many residents. The chlorine levels may also vary according to where you live, which is why several Oshawa homes and businesses have water purification systems or drinking systems installed. 

Some places may also opt for additional filtration due to an old plumbing system. Understanding the water quality challenges in Oshawa helps you effectively address the concerns in your water.

Where Does Tap Water in Oshawa Come From?

The municipal or tap water in Oshawa comes mainly from Lake Ontario and is treated by the municipal system serving the whole Durham Region. The regional water treatment facilities disinfect the water and distribute it to the city’s businesses, facilities, and homes. 

The treated tap water in Oshawa does meet the set standards by Health Canada and the Ontario Ministry of the Environment, Conservation and Parks. However, that water also lies in the ‘moderately hard to hard’ category, with an average of 7.3 grains per gallon. These hardness levels can alter the taste of water and also cause scale buildup in pipes, dishwashers, water heaters, washing machines, and other water-using appliances. 

The chlorine usage can also be problematic, as many Oshawa residents complain of a chlorine smell and taste in their tap water.   Water quality here may also change due to seasonal fluctuations. Warmer months may cause higher organic matter levels in the lake, which in turn affects the taste and smell of treated tap water. If you’re in an older area, the plumbing infrastructure might be more susceptible to sediment or metal contamination.

Learning about Oshawa’s water quality can be unsettling, and it is natural to be concerned about your tap water. Instead of relying on guesswork, find out exactly what’s in your water with WaterMart’s FREE professional test. Additionally, they also provide customized solutions to address the identified issues.

FAQs About Water Filter Systems

Check out common questions we get below.

Chlorine is commonly added to municipal water supplies in Durham Region to disinfect the water and eliminate harmful bacteria. Depending on how close your home is to the treatment facility and the amount used during treatment, you may sometimes notice a stronger chlorine smell or taste. Installing a carbon filter or a multi-stage reverse osmosis system can effectively remove chlorine and improve the taste and smell of your tap water.

No, home water filtration systems simply connect to the current water line in your home and don’t increase water usage by any significant amount. There might be some wastewater from RO systems, but the modern models from WaterMart are efficient enough to get you long-term savings on appliance repairs and bottled water purchases. These savings will more than cover any increase in expenses.

The water hardness of Oshawa’s water is around 125 mg/L or 7.3 GPG, which is similar to the neighboring towns of Whitby and Ajax in the Durham Region. However, it differs from the water hardness in Toronto, which also serves regions like Scarborough. The Oshawa water hardness falls in the moderately hard to hard categories, which makes water softeners and water filter systems an important addition for most residences.

Oshawa residents most commonly complain about the taste of chlorine and metallic elements in their water. They can remove such issues by using activated carbon filters or a more comprehensive treatment like a multi-stage RO system. The RO system removes traces of metals, chemicals, and dissolved solids as well as debris and particles in the water supply to get cleaner, fresher results. Get a free Watermart water test to determine what’s causing the unpleasant taste in your water.

Certain water filter systems, like faucet-mount or countertop models, are suitable for DIY installations. For a whole-house system, however, professional installation is the right choice to make sure that you have secure connections, optimal function, no leaks, and warranty coverage. You can contact WaterMart to get professional water filter installation anywhere in Oshawa. Most home-based installationss take a maximum of 2 to 4 hours.

Yes, WaterMart provides complimentary water testing for Oshawa homeowners and residents. Our test checks the water hardness, chlorine levels, TDS (Total Dissolved Solids) levels, and other traces that are specific to the Durham region water. The test results will be accompanied by a customized system recommendation with no strings or obligations attached. Book the free water test online or call us to schedule an appointment.
