Week 11
Water and Wastewater Systems
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
Week 11   class notes
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!
Water users
• What type of hotel uses most water?
• How much? Total or per day?
Water turns to Sewer?
• Often hotels pay sewer fees based on water
consumption. Is that correct?
– WHAT GOES IN, GOES OUT?
Water sources
• City versus remote resort
• Hooking into the town water pipeline
Week 11   class notes
Durrat Al Bahrain Desalination Plant, Bahrain
Cost: $ 30M
• Human uses: drinking, bathing, cooking,
washing
• Equipment uses: kitchen, laundry, spa, pool,
heating and cooling, landscaping
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%
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
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
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)
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
Legionnaire’s Disease
• http://www.youtube.com/watch?v=KAgA-3l3P_0
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
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
Saline Pool Water treatment
• No Chlorine
• No red eyes
• Environmentally friendly
• Great for indoor pools (no chlorine “clouds”)
Water conservation
• All teams task:
– Write a water conservation plan for our project
hotel
– Present at next week’s class
Next Class
Organization of the Maintenance Department
