In 2000, total demand was approximately 5,842 million gallons, with potable water accounting for 80% and reclaimed wastewater for 16%. The report highlights a significant reliance on groundwater, often from deep and costly wells, and the critical role of wastewater reclamation in communities like Tusayan, where it meets 40% of demand. It identifies a wide disparity in conservation efforts, with Flagstaff having the most extensive program and Page lacking a serious initiative. The document concludes by proposing a Phase II forecasting methodology that uses population projections and water-use models to create baseline, moderate, and aggressive conservation scenarios.","ai_generated":true,"unit":"rmi-000963#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"In 2000, the total water demand for the study area was approximately 5,842.4 million gallons (17,930 acre-feet), consisting of 80% potable demand, 16% reclaimed wastewater, and 4% raw water.","ai_generated":true,"unit":"rmi-000963#insight-1","date_modified":"2026-10-23"},{"text":"Water demand is highly seasonal due to tourism and irrigation, with peak summer demand typically 1.5 to 2.5 times higher than winter demand; this is more extreme in Page (4 times) and Tusayan (3 times).","ai_generated":true,"unit":"rmi-000963#insight-2","date_modified":"2026-10-23"},{"text":"Groundwater is the primary source for most communities, but drilling is expensive and risky due to extreme depths, reaching over 3,000 feet in Williams, Valle, and Tusayan.","ai_generated":true,"unit":"rmi-000963#insight-3","date_modified":"2026-10-23"},{"text":"Wastewater reclamation is a significant supply source, providing 16% of total regional demand and serving as a primary supply in six communities, most notably Tusayan where it meets 40% of total demand.","ai_generated":true,"unit":"rmi-000963#insight-4","date_modified":"2026-10-23"},{"text":"Rainwater harvesting provides a notable potable supply at the Grand Canyon airport in Tusayan, meeting 6% of the community's total water demand.","ai_generated":true,"unit":"rmi-000963#insight-5","date_modified":"2026-10-23"},{"text":"Water efficiency and conservation programs vary greatly; Flagstaff has the most extensive program, while Page is noted for not having implemented a serious program despite concerns over future growth.","ai_generated":true,"unit":"rmi-000963#insight-6","date_modified":"2026-10-23"},{"text":"High water prices often act as a conservation tool by default due to the high cost of supply, but only Doney Park Water, Flagstaff, and Kachina Village have effective conservation rate structures.","ai_generated":true,"unit":"rmi-000963#insight-7","date_modified":"2026-10-23"},{"text":"The authors express reservations about the 1999 ADWR water demand estimates, noting they may underestimate 2000 demand by 10% to 24% and lack documented methodology.","ai_generated":true,"unit":"rmi-000963#insight-8","date_modified":"2026-10-23"},{"text":"The proposed Phase II forecasting methodology will use a 'per account' basis tied to population projections from the Arizona Department of Economic Security (ADES).","ai_generated":true,"unit":"rmi-000963#insight-9","date_modified":"2026-10-23"},{"text":"Phase II will develop three demand scenarios: Baseline (current efforts), Moderate conservation and alternative supply investment, and Aggressive conservation and alternative supply investment.","ai_generated":true,"unit":"rmi-000963#insight-10","date_modified":"2026-10-23"}],"climate_tags":["wastewater treatment","water efficiency","water conservation","rainwater harvesting","drought"],"geography_discussed":["Flagstaff","Page","Williams","Tusayan","Grand Canyon Village","Lake Powell"],"frame_perspective":[],"analysis_type":["demand assessment","resource evaluation","methodological proposal"]}]}
