Allan Water Is Very Hard — Here's What It Costs You Each Year

Why Is Allan Water So Hard?

Allan doesn’t draw its water from a local well or aquifer. The town is supplied through the SaskWater Saskatoon East Potable Water Supply System, which means the tap water in Allan actually starts its journey in the South Saskatchewan River, treated at the City of Saskatoon’s water plant. That’s surface water, plain and simple, and it explains a lot about why your water measures at 10.53 GPG, which puts it right at the “very hard” threshold.

Here’s the geology in plain terms. The South Saskatchewan River doesn’t start in a pristine mountain spring. It gathers its flow from the Rocky Mountains and the vast prairie drainage basin of southern Alberta and Saskatchewan, and on its long run east it cuts through and over some seriously mineral-rich ground. The river’s watershed is dominated by limestone, dolomite, and shale formations, along with glacial till left behind by the last ice age. Rain and snowmelt percolate through that terrain, and as the water moves, it dissolves calcium and magnesium carbonate right out of the rock. That’s the whole story of hardness: calcium and magnesium ions dissolved into the water. The longer the water stays in contact with those mineral deposits, and the more ground it covers, the more of those ions it picks up.

The South Saskatchewan is a big, slow-moving prairie river by the time it reaches Saskatoon. It’s not like a mountain stream tumbling over granite, which is relatively inert. This river has spent weeks, sometimes months, soaking up dissolved minerals from the limestone-heavy soils and the clay-rich glacial deposits of the northern plains. By the time Saskatoon pulls it from the river, treats it, and sends it down the pipeline to Allan, the water is already carrying a heavy load of dissolved calcium and magnesium. Treatment at the plant typically addresses turbidity, pathogens, and disinfection, but hardness is not something municipalities remove. It’s not a health concern, so it stays in the water all the way to your tap. That’s why Allan’s water sits at 10.53 GPG, firmly in the very hard category, and it’s also why you’re likely seeing scale on faucets and film on glassware. You’re not imagining it. The water is genuinely loaded with minerals, and it’s a direct result of the river’s long journey through mineral-rich prairie geology.

How Allan Compares to Nearby Cities

Because Allan is tied into the Saskatoon East PWSS, its water quality is essentially identical to what comes out of the taps in Saskatoon itself. The water is treated at the same plant and pumped through the same regional system. So when you fill a glass in Allan, you’re drinking the same mineral profile as someone in Saskatoon’s east side. That means if you’ve ever noticed hard-water spots on dishes at a relative’s place in Saskatoon, you know exactly what Allan’s water is like. Same source, same hardness, same scale buildup.

Other communities in the region that are also served by SaskWater’s Saskatoon East system, such as those in the surrounding rural municipalities, draw from that same treated South Saskatchewan River supply. They’re all in the same boat. The hardness doesn’t vary much between one town and the next because it’s all coming from the same treatment plant and the same river. The mineral content is set upstream, before the water ever reaches the distribution system.

That said, not every town in the area shares this situation. Some smaller communities in central Saskatchewan still rely on local groundwater wells, and those can be a different story entirely. Groundwater in this part of the province often comes from deeper aquifers, which can be either harder or softer than the river water, depending on the specific geological formation they tap into. Some wells draw from sandstone aquifers that produce moderately hard water, while others hit zones with much higher mineral content. But for Allan specifically, the comparison is straightforward: your water is Saskatoon’s river water, and it’s very hard because the South Saskatchewan River picks up calcium and magnesium from the limestone and glacial deposits it flows through. If you’re comparing notes with a neighbor in a town on a different supply, the difference comes down to source, not treatment. Surface water from the river is what Allan gets, and that’s what makes the hardness what it is.

How does Allan stack up against the rest of Saskatchewan? It's very hard at 10.53 GPG — White City, Edenwold, and Emerald Park sit nearby with different numbers. See the full hardest-water ranking for context.
