Calgary Has Some of the Hardest Water in Canada
Calgary's municipal water is sourced from the Bow and Elbow rivers and contains high levels of calcium and magnesium — typically 16–20 grains per gallon (GPG). Anything above 7 GPG is considered hard. This means your pipes, appliances, skin, and dishes are under constant stress.
Left untreated, hard water silently reduces the efficiency of your water heater by up to 30%, shortens appliance lifespan by years, and costs Calgary homeowners hundreds of dollars annually in excess detergent, energy, and premature repairs.

Signs You Need Water Treatment in Calgary
Hard water damage is often invisible until it's expensive. Recognize these signs early and protect your home.
Scale & Limescale Buildup
White crusty deposits on faucets, showerheads, kettles, and inside pipes. Hard water scale narrows your pipes over time and is expensive to fix.
Dry Skin & Brittle Hair
Hard water minerals block your skin's pores and strip natural oils. After showering you feel itchy, tight, or irritated — a common Calgary complaint.
Spotty Dishes & Cloudy Glasses
Calcium deposits leave white film on glasses, dishes, and stainless steel even after washing. A telltale sign of hard water in Calgary.
Reduced Appliance Life
Scale coats the heating elements of dishwashers, washing machines, and water heaters. This lowers efficiency by up to 30% and shortens lifespan by years.
Bad Taste or Chlorine Smell
Water that tastes metallic, smells of chlorine, or has an unpleasant earthy odor. Filtration or RO systems eliminate this completely.
High Energy Bills
Scale-coated heating elements must work harder to heat water. A water softener can cut your water heating costs by 20–30% per year.
Our Water Treatment Services in Calgary
From whole-home softeners to under-sink reverse osmosis systems, we design the right solution for your home's water chemistry and budget.
Water Softeners
Ion-exchange water softeners remove calcium and magnesium — the minerals that cause Calgary's famously hard water. The result: softer skin, spot-free dishes, longer-lasting appliances, and up to 30% savings on water heating. We supply and install top-brand softeners sized specifically for your household water usage.
- Prevents scale buildup in pipes & appliances
- Reduces soap and detergent usage by 50%
- Protects water heater, dishwasher & washer
- Whole-home treatment from the water main
Whole-Home Water Filtration
Our whole-home carbon and sediment filter systems treat every tap in your house — from the shower to the kitchen sink. Removes chlorine taste and odor, sediment, rust, and other particles present in Calgary's municipal supply. Ideal as a standalone solution or paired with a water softener.
- Chlorine & chloramine removal
- Sediment, rust & particulate filtration
- Better-tasting water from every tap
- Low maintenance — filter changes every 6–12 months
Reverse Osmosis (RO) Systems
Reverse osmosis pushes water through a semi-permeable membrane at the molecular level, removing up to 99% of all dissolved contaminants. Our under-sink RO systems provide bottled-water quality right from your kitchen tap, eliminating lead, fluoride, nitrates, pharmaceuticals, and more.
- Up to 99% contaminant removal
- Better than bottled water — at a fraction of the cost
- Under-sink installation — out of sight
- Dedicated RO faucet included
Water Testing & Assessment
Not sure what's in your water? We offer comprehensive water testing to measure hardness, pH, chlorine levels, iron content, and bacterial presence. Our licensed technicians interpret the results and recommend the right treatment system — no guesswork, no upselling. We match the solution to your actual water chemistry.
- Hardness, pH, chlorine & iron testing
- Bacterial & contamination screening
- Written report with recommendations
- Free in-home assessment available
Hot Water Tank Treatment
Scale accumulation inside water heaters is one of the leading causes of premature failure in Calgary. We flush, descale, and service your hot water tank — and can install a dedicated scale inhibitor to prevent future buildup. Pair with a water softener for maximum protection and efficiency.
- Descaling & sediment flush
- Anode rod inspection & replacement
- Scale inhibitor installation
- Pairs with water softener for best results
Water Heater & Boiler Scale Protection
Your boiler and water heater are the most vulnerable to scale damage. We install inline scale protection systems and offer periodic maintenance to keep your heating equipment operating at peak efficiency. This is especially important in Calgary, where hard water can cut water heater efficiency in half within just a few years.
- Inline polyphosphate scale inhibitors
- Boiler water chemistry testing
- Annual maintenance plans available
- Extends equipment life by 5–10 years
