Leduc takes the September 2026 Water System of the Month slot in the OpenStats civic arena. Below: how we grade the system, what the chemistry row says, where supply and treatment data come from, and which numbers are measured versus estimated. Every figure is from repo data or a cited public source — no filler stats.

Why this system matters

Leduc operates one of Canada's most distinctive municipal drinking-water systems. The City of Leduc is contracted to manage and operate the CRSWSC itself, so the same municipal staff run both regional transmission oversight and local utility service.

On the OpenStats water atlas, Leduc carries a direct-tier hardness reading and an OpenStats letter grade of C (Fair). Among 343 direct-tier cities on the atlas, Leduc ranks #277 for hardness at 117 mg/L (moderate). The Alberta average across tracked municipalities is about 176 mg/L.

Supply and treatment

Source type on the atlas: surface. Named source waters include North Saskatchewan River.

Treatment assets named in OpenStats supply research: EPCOR E.L. Smith and Rossdale plants — wholesale via CRSWSC (Capital Region Southwest Water Services Commission buys treated water from EPCOR and transmits it to Leduc and other southwest capital-region members.).

CRSWSC booster station on Highway 2 south feeds a transmission main into Leduc with laterals to Beaumont, Calmar, Leduc County, the Edmonton International Airport, and other members. Leduc operates local distribution, flushing, and backflow programs.

OpenStats score and ranking context

OpenStats grades drinking water A through D using Health Canada guideline limits on pH, lead, fluoride, chlorine, and turbidity, with a B grade when health parameters comply but hardness exceeds 180 mg/L or turbidity sits above the typical 1 NTU target. Leduc scores C on the current row: Fair.

Hardness 117 mg/L is on the atlas as a direct-tier row. That figure is 59 mg/L below the Alberta average (176 mg/L across 51 tracked municipalities).

What is measured vs estimated

OpenStats labels every parameter row. Hardness on direct-tier cities comes from a cited municipal or regional report. pH is only treated as measured when the same verified source published it. Lead, fluoride, chlorine, and turbidity on this page remain atlas seed values unless the data_source field names a municipal lab report.

For Leduc, hardness is verified from ECCC / municipal open data (seed). pH 7.5 is an atlas seed value, not quoted from the hardness study. Other health parameters in the table below are seed rows and should not be read as a current compliance certificate.

Always open the City of Leduc annual water services reports linked in the supply profile for operational compliance data.
