Data & sources

Every figure this tool uses traces to a public source listed below. This is a manual seed dataset, refreshed periodically — nothing is scraped at report time. Each entry states exactly what a reviewer must confirm on the live page to move it from unverified to verified.

Only sources with status verifiedmay back a paid report. Seed entries are quoted with their claim and a “to verify” instruction until a reviewer confirms them.

01

Municipality capacity & drought status · 12

What each municipality's utility, region, or civil protection has said on the record — emergencies, refusals, constraints.

02

Water-demand coefficients · 5

The published figures behind the demand model — guest-night demand, pool top-up, peak-day multiplier, wastewater return.

  • Tourism and Water Use: Supply, Demand and Security — an International Review (Greek Aegean ≈450 L/guest-night; global avg 222 L/tourist/day)

    Gössling et al., Tourism Management · 2012 · Academic

    backs: Demand modelverified

    To verify · CONFIRMED (browser, 2026-07-10, via indexed text + citing reviews; ResearchGate page itself CAPTCHA-blocked): Greek Aegean ≈450 L/guest-night; global avg 222 L/tourist/day. NOTE: the ~880 L luxury figure is Majorca (UNEP 2004), NOT the Greek Aegean.

  • Hotel water consumption at a seasonal mass-tourism destination (Mallorca): 3★≈224, 4★≈285, 5★≈594 L/guest-night

  • Swimming-pool evaporative water loss and use in the Balearic Islands (avg 4.4 L/m²/day; July peak ~6.5)

    Hof et al., Water 10(12):1883 (MDPI, open access) · 2018 · Academic

    backs: Demand modelverified

    To verify · CONFIRMED (browser, 2026-07-10, MDPI open access): Balearic average 4.4 L/m²/day; July peak ~200 mm/month ≈ 6.5 L/m²/day. Our value 6 is a peak-summer top-up (between avg and July peak) — defensible but note it exceeds the annual average.

  • Design Guidelines for Drinking-Water Systems, Ch. 3 Table 3-1 (maximum-day factor 1.5 for large systems, up to 2.75 for small)

    Ontario Ministry of the Environment, Conservation and Parks · 2008 · Official

    backs: Demand modelverified

    To verify · CONFIRMED (browser, 2026-07-10): citable government engineering guideline; max-day factor 1.5 (large systems) → 2.75 (small). Our value 1.3 is a conservative mid-choice below the 1.5 upper bound; if exact URL differs, this is the guideline to cite.

Methodology

Verification workflow

How a source moves from seed to verified — and why an unconfirmed claim gets downgraded, never left standing.
  1. 1Open each source URL above from an unrestricted network.
  2. 2Confirm the exact claim in that entry's “To verify” line (figure, date, wording).
  3. 3In src/lib/crete/data.ts (or coefficients/comparables), set the source's status to "verified", fill lastChecked with today's date, and correct the date/figure if the page differs.
  4. 4If the page is gone or the figure doesn't match, downgrade the record (e.g. capacityStatus → "unknown") rather than keep a stale claim.
  5. 5Only sources with status: "verified" should back a report issued to a paying customer.

The methodology and field-by-field provenance is documented in src/lib/crete/datasources.md.
