  • 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

    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

    Deyà Tortella & Tirado, J. Environmental Management 92:2568–2579 · 2011 · Academic

    Demand modelverified

    To verify: CONFIRMED (browser, 2026-07-10, via secondary citations; ResearchGate page CAPTCHA-blocked): 3★=224 / 4★=285 / 5★=594 L/guest-night (also 1★/2★ = 208/247). Mallorca-specific, not Greek.

  • 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

    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

    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.

  • Urban Drainage (3rd ed.) — dry-weather-flow / wastewater return coefficient (fww ≈ 0.75–0.85; 0.85 typical)

    Butler & Davies, CRC Press · 2011 · Academic

    Demand modelverified

    To verify: CONFIRMED (browser, 2026-07-10, via secondary citations incl. Duque et al. 2022): standard sewerage-design return coefficient 0.75–0.85 (fww=0.85 common). Textbook reference; our value 0.8 is mid-range.

  • Texto Refundido de la Ley de Aguas (RDL 1/2001), Art. 25.4

    BOE · 2001 · ES · Statute

    Spain — Art. 25.4 comparableverified

    To verify: CONFIRMED (browser, 2026-07-10) from the official consolidated text: the basin-authority report "se pronunciará expresamente sobre la existencia o inexistencia de recursos suficientes" and "se entenderá desfavorable si no se emite en el plazo" (silence = unfavorable).

  • El agua y el desarrollo urbanístico: la suficiencia de recursos hídricos

    elderecho.com · 2019 · ES · Press

    Spain — Art. 25.4 comparableverified

    To verify: CONFIRMED (browser, 2026-07-10): case law treats the report as "determinante" / "materialmente vinculante"; the 2005 reform gave a missing report "sentido desfavorable."

  • Más de 90 planes de urbanismo anulados judicialmente por no justificar la disponibilidad de recursos hídricos

    J. A. Ramos Medrano, Actualidad Jurídica Ambiental n.º 67 · 3 Apr 2017 · ES · Academic

    To verify: CONFIRMED (browser, 2026-07-10): exact title match; >90 plans annulled for failing to justify water availability; AJA n.º 67, 3 Apr 2017.

Verification workflow

  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.
