Similar to other nearby areas, Newmarket’s municipal water comes from a combination of Lake Ontario water and local groundwater. The water is treated with various chemicals to protect residents from pathogens and lead contamination. The water is also moderately to very hard. Newmarket residents need to make informed choices to ensure their home plumbing remains safe and reliable.
Newmarket's water supply
Floods in Newmarket have been more common than some other areas nearby
The 1954 Hurricane Hazel flood brought severe flooding and destruction along the Holland River. The main street was impacted.
In September 2006, heavy rainfall caused widespread flooding on Avenue Road, Lewis Drive, Amelia Street, and Park Avenue. There were evacuations and widespread damage to homes.
More recently, in April 2025, Newmarket experienced flooding on parts of Tom Taylor Trail.
On the Lake Simcoe Region Conservation Authority Floodplains Map, there are several rivers that flow through Newmarket, and some neighbourhoods are particularly at risk of floods.
We especially recommend considering sump pumps and back-up sump pumps if you happen to live in a floodplain, near a stormwater pond, or other bodies of water.
There are galvanized pipe concerns in Newmarket
Galvanized Metal Health Risks
If your home or structure in Newmarket was built before 1969, your pipes might have galvanized piping. These pipes are dipped in a zinc coating, but decades of exposure to water can cause galvanized pipes to rust and corrode. This can clog pipes, discolour water, and cause leaks.
Harris Plumbing can help you identify and resolve galvanized piping issues within your home, and replace them with copper or PEX pipes which are durable and much safer to use in the home. We also provide annual home inspections in Newmarket to ensure your plumbing systems continue to run optimally and support you and your family or business.
Water quality is decent in Newmarket.
Chlorine, Phosphorus, Fluoride, and Ammonia are added to Newmarket’s water.
Newmarket residents get water from York Region. Due to this, Newmarket residents can expect a host of chemicals common to Southern Ontario municipalities like chlorine, fluoride, ammonia, and phosphoric acid in their water.
These additives are quite safe on a daily basis to consume and use, but Harris Plumbing recommends further treatments to get the best water for your health and home.
The impacts of long-term exposure to these chemical additives are not yet conclusively known, but there are possible health concerns, particularly with by-products of chlorine and chloramines in water.
If you want to reduce exposure to potentially harmful chlorine, chloramines, and chlorine-related by-products like Trihalomethanes, Harris Plumbing can replace, install, or repair high-quality whole-home chlorine filters in Newmarket. We are also proud to source our products from a Canadian supplier.
For people with existing health conditions, water quality might matter more. When taking hot showers or bathing, chlorine gases can irritate lungs and eyes, and cause dry skin and scalp. Whether you already experience skin or lung problems, we highly recommend chlorine filtration in Newmarket.
Drinking Water in Newmarket
Pure, Safe, Drinking Water
For drinking water, Harris Plumbing recommends Reverse Osmosis filters in Newmarket for kitchen sinks and refrigerator water and ice dispensers. For us, this is an almost universal recommendation for all municipalities and townships across our operating area.
Reverse Osmosis water is the benchmark for clean drinking water because it filters a lot of what might still lurk in our water even after the municipalities have treated it. Trace heavy metals, hardness and dissolved minerals, and other impurities like sediments and dissolved gases can still exist in your tap water. For everyday life, Reverse Osmosis water means clean, great-tasting drinking water, often superior to what you find in plastic water bottles. For cocktail aficionados and those who love to entertain, Reverse Osmosis means much cleaner-tasting ice and clearer-looking ice!
We recommend Water Softeners in Newmarket
Newmarket has moderately hard water, sitting at around 8 to 15 grains per gallon on average. Similar to the water in regions around Newmarket, this is a level of hardness where soap scum can build up around bathroom and kitchen fixtures. Limescale will build up inside coveted espresso machines, dishwashers, hot water tanks, and other water-based appliances.
Hard water limits the lifespan of precious appliances, affects the taste of water, and causes extra cleaning duties to get rid of scum build up in showers, tubs, and sinks.
Harris Plumbing carries top-quality water softeners you cannot find in hardware stores. We have over 50 years of experience installing and maintaining top-quality water softeners and other water filtration devices. We can help you make an informed choice about water softeners in Newmarket.
Defend Against Sewage Back-ups with Backwater Valves in Newmarket
If your home is in a low-lying area, or if you’ve experienced sewage floods before, a backwater valve is highly recommended. Some low-lying areas in Newmarket include areas along the Holland River, Fairy Lake, Mckenzie Wetland, or other bodies of water.
Call Harris Plumbing and we will guide you through the process of getting a backwater valve installed.
