The claims,
in their own words.

UN Sustainable Development Goal 6 reads, in full: “Ensure availability and sustainable management of water and sanitation for all.” Its eight targets cover access to safe drinking water and sanitation, water quality, efficient use, ecosystem protection, and community participation in governance. There is no enforcement mechanism, no transfer of authority to the UN, and no legal obligation on Canadian municipalities. Canada implements SDG 6 through existing federal, provincial, and municipal programs — the Government of Canada’s headline national target under SDG 6 is resolving long-term drinking-water advisories on First Nations reserves, not metering Calgary lawns.

Calgary’s authority over its water system comes from Alberta’s Water Act and the Municipal Government Act, not from the UN. The Water Efficiency Plan is a local document approved by Calgary City Council, addressing local infrastructure (leak reduction, meter replacement, peak-day management). Framing it as “global centralised control” requires ignoring how Canadian water governance actually works.

The 150 L/p/d figure in the plan is the residential target by 2040. The City’s most recent published open-data series shows single-family residential use around 213–243 L/p/d (2010–2017). The headline reduction target in the plan is a 20%reduction in city-wide per-capita demand by 2040, not 50%. The “300” figure in the claim matches neither the residential nor the city-wide baseline (city-wide total per-capita was 356 L/p/d in 2023, per the City of Calgary engagement page).

The figure is roughly correct: Calgary’s Bow River licence allocation is around 460,000 ML/yr (per CBC reporting on Alberta water-licence data, Mar 2024), and recent withdrawals are around 200,000 ML/yr — about 43%. But the implication that unused-licence headroom means the Plan is unnecessary is wrong. A licence cap is the legal upper bound; it is not the volume the river can sustainably yield in low-flow years. The Plan’s operational cap (233,000 ML/yr) is set well below licence specifically to stay within river-ecology limits during droughts. See the withdrawals chart for both reference levels.

The 22% figure is from the City’s own published data — see the sector-shares chart. But the figure is non-revenue water, not exclusively physical pipe leaks. NRW includes meter undercounting and authorised-but-unbilled use (firefighting, mains flushing) as well as real losses. The Plan’s leak-specific target is Infrastructure Leakage Index 3.0 by 2030; the meter-replacement target (100% advanced metering by 2031) addresses the apparent-loss portion. Citing the City’s self-reported diagnostic as an argument against the plan that proposes to fix it is the opposite of what it implies.

The directional claim understates the actual reduction: withdrawals per resident fell from 616 L/p/d in 1997 to 389 L/p/d in 2023 — about 37% across 26 years, while population almost doubled. See the per-capita chart and the withdrawals + population overlay. But the “voluntary effort” framing is wrong: the 2005 Water Efficiency Plan included mandatory measures (universal metering, rate structures, regulations) alongside education. The reduction came from a coordinated programme, not goodwill alone.

The dollar figure is essentially correct: CD2026-0150 Attachment 8 puts Advanced Meter Infrastructure at $161M (capital, 2027–2030). But the framing as the headline cost is wrong. The Plan’s 2027–2030 envelope is $354M–$420M total; the largest single line is $179M for the Accelerated Water Loss Program (pipe replacement, leak detection, copper-lead service replacement). See the budget chart. “Surveillance” is editorial framing of standard utility metering — advanced meters detect undercounting and customer-side leaks, both of which the Plan separately targets.

The petition contains no quantitative claims about water use or the plan. The implicit framing — that infrastructure failures and the Water Efficiency Plan are competing priorities — is contradicted by the plan itself, which directs spending toward leak reduction and meter replacement. See the 22% leakage share on the sector-shares chart.
