    1. 1. Hospitality Facilities Design and Planning Week 11 Water and Wastewater Systems
    2. 2. Program today • 4:00-5:15 Jason Lisai – Sugarbush Resort • 5:30-6:00 Water and Wastewater Systems • 6:00-6:45PM Project update from all teams
    3. 3. Uses of water in a hotel • Drinking • Sanitary use • Cleaning • Cooking • Laundry • Pools, hot tubs • Landscaping • Fire Safety • Etc etc etc – you get the point!
    4. 4. Water users • What type of hotel uses most water? • How much? Total or per day?
    5. 5. Water turns to Sewer? • Often hotels pay sewer fees based on water consumption. Is that correct? – WHAT GOES IN, GOES OUT?
    6. 6. Water sources • City versus remote resort • Hooking into the town water pipeline
    7. 7. Durrat Al Bahrain Desalination Plant, Bahrain Cost: $ 30M
    8. 8. • Human uses: drinking, bathing, cooking, washing • Equipment uses: kitchen, laundry, spa, pool, heating and cooling, landscaping
    9. 9. Water use reduction • Laundry: example AQUARECYCLE – 1,200 room Hilton in Houston, Texas monthly water use down to 157,000 gallons from 630,000 or a drop of 75%
    10. 10. Commercial – TU 21-60 (WSC 3, 5, 6): Consumption is no longer included with the basic charge. The volume charges are applied to all usage. Rate Meter Size (Inches) Basic Water Charge Basic Sewer Charge Basic Charge (0 consumption) 5/8 $4.51 $7.93 3/4 $4.65 $7.93 1 $5.59 $8.33 1.5 $8.46 $9.66 2 $9.96 $10.06 3 $26.36 $18.02 4 $35.93 $20.41 6 $61.58 $29.17 8 $160.79 $70.84 10 $160.79 $86.10 Volume Charge All + $3.56 per 1,000 gallons + $5.04 per 1,000 gallons
    11. 11. Houston Hilton Example • $3.56/1000 gallons water cost • $5.04/1000 gallons sewer cost • Savings: – 473 x $3.56 water = $1,700 – 473 x $5.04 sewer = $2,400 – Total per month: $4,100 or almost $50,000 per year
    12. 12. Wastewater – two kinds: Storm = • Rain water removal • Goes into local streams Sanitary = • Waste product from the hotel • Goes into wastewater treatment facility (some properties have own)
    13. 13. Water Quality • Drinking water: Some systems in Vermont using well or spring water -> regulations: testing – Primary concern: contamination (too close to septic system) or fertilizers, pesticides, etc. – Secondary: hard water: use of water softeners
    14. 14. Legionnaire’s Disease • http://www.youtube.com/watch?v=KAgA-3l3P_0
    15. 15. Hot Water • Uses: – Heating of building – Guest use – Laundry, kitchen, etc. – Importance of mixing valves and limiting temperature http://www.tap-water-burn.com/pamphlet/abstract.htm
    16. 16. Swimming Pools • Complicated • Balance between water temperature and acidity/alkalinety (pH balance) • Common treatments: chlorine and more often ozone, ionization and other chemicals • Better: saline treatment
    17. 17. Saline Pool Water treatment • No Chlorine • No red eyes • Environmentally friendly • Great for indoor pools (no chlorine “clouds”)
    18. 18. Water conservation • All teams task: – Write a water conservation plan for our project hotel – Present at next week’s class
    19. 19. Next Class Organization of the Maintenance Department
