Drinking Water for Office Uses
Boiled Tap Water
Boil tap water with the use of electric kettle or boiler
Bacteria mostly killed but contaminants remain
Bottled Water
Tap water is treated with purification and/or distillation
processes and bottled for deliveries to consumers
POU ( Point-of-Use ) Filtered Water
POU Water Filtration System removes contaminants and/or
bacteria right from the tap prior to immediate consumption
2
www.aquapura.com.hk
Boiled Tap Water
Bacteria mostly killed but contaminants, chemicals & harmful
substances would still remain
Odor and taste of water same as what it is
Would need to refill water frequently
Water scale and contaminants accumulatively deposited in
kettle and boiler tank
Studies show repeated heat-up of deposited contaminants in
kettle and boiler increases the risk of cancers

www.aquapura.com.hk
Bottled Water (1)
Types of Bottled Water
Distilled water
Purified tap water
Spring Water
Quality of Bottled Water
Defined as “food” under current regulations which are
even LOOSER than the standards of tap water
Bottled water does not necessarily offer purer water
than tap water
4
www.aquapura.com.hk
Bottled Water (2)
Impacts of Bottled Water on Environment
CO2 Emission due to transportation of bottled water to consumers
Energy required to manufacture plastic bottles
Pollution caused by improper disposal of plastic bottles
Health Impact due to Re-Use of Plastic Bottles
5
More and more Phthalate (鄰苯二甲酸酯) would leach into bottled water as the
bottles : Get aging
Exposed in direct sun-light at transportation/delivery
Cleaned in high-temperature disinfection process for re-use

POU Filtered Water (1)
Main Classes of Water Filtration Systems
(MF) Microfiltration
(UF) Ultrafiltration
(NF) Nanofiltration
(RO) Reverse Osmosis
Freshly “brewed” purified water right from the tap
Important to select reliable filtration system of premium quality from
reputed supplier
May require extra piping works prior to installation
Bottled water dispensers need to be replaced
Need to change filters regularly

How do they compare? (1)
Distilled Water
Distillation process utilizes a heat source to vaporize water
Pure / Mineral-Free / pH ≦ 7
Slowing down human body’s metabolism system because it
is slightly acidic
Acidic
Unhealthy
Mostly used in developing countries
Neutral

Neutral
pH
Alkaline
Healthy
Reverse Osmosis Water
Viable replacement option to the costly and energy-wasteful
distilled water
Recognized decontamination capabilities in water industry
Pureness close to distilled water and usually alkaline
Still having solvable micro-minerals
10
www.aquapura.com.hk
How do they compare? (2)
Nano-Filtration Filtered Water
Sufficient in removing known contaminants / chemicals / harmful substances
Still retaining mineral & ion contents of water supplies
Weak alkaline - pH value same as water supplies ( 8.5 in average )
Widely used in beverage industries

Costs Comparison ( I )
Assumptions
Working Days per Year is ( 52 weeks x 5 days ), i.e. 260 Working Days
Drinking Water Consumption per Staff per Day is 4 glasses of 250 ml each , thus
Yearly Consumption per Staff = ( 250 ml/day x 4 x 260 days ) , that is
13.75 Bottles of 5-gallon bottled water, where ( 5 gallons = 18.9 liters )
Fixed Costs are to be amortized in a 3-year period. Filtered Water is more advantageous, if the amortized
period is longer, like 4 or 5 years
Filters of Filtered Water Dispenser are to be replaced Twice ( 2 ) per Annum
Water Dispenser costs and Water costs are detailed in Appendix A
13
www.aquapura.com.hk
Costs Comparison ( II )
Calculations
Annual Fixed Costs in First 3 Years = ( Dispenser Costs ) / ( 3-year Amortized Period )
Aqua Pura Filtered Water ( RO's ) = $9,100 / 3 = HK$3,033
( NF's ) = $7,580 / 3 = HK$2,527
Watson's = [$4,050 – ( 50 x $65.9 )] / 3
* Free vouchers - 50 bottles of water
= $755 / 3 = HK$252
Bonaqua's = [$2,680 – ( 35 x $30 )] / 3
* Free vouchers - 35 bottles of water
= $1,630 / 3 = HK$543
Annual Variable Costs = ( Filter Replacement Costs ) + ( Water Costs )
Aqua Pura Filtered Water
* Tap Water costs $0.12 / 5-gallons - see Appendix A for details
( RO ) = ( $1,900 ) + ( 13.75 bottles / year x No. of Staff x $0.12 / bottle )
( NF ) = ( $1,850 ) + ( 13.75 bottles / year x No. of Staff x $0.12 / bottle )
14
www.aquapura.com.hk
Costs Comparison ( III )
Annual Variable Costs = ( Filter Replacement Costs ) + ( Water Costs )
Watson's = ( $0 ) + ( 13.75 bottles / year x No. of Staff x $65.9 / bottle )
Bonaqua's = ( $0 ) + ( 13.75 bottles / year x No. of Staff x $29.98 / bottle )
Annual Total Costs
Aqua Pura Filtered Water's
( 1st ~3rd Year ) :
( RO ) = $4,933 + $1.65 x No. of Staff
( NF ) = $4,377 + $1.65 x No. of Staff
( 4th Year & After ) :
( RO ) = $1,900 + $1.65 x No. of Staff
( NF ) = $1,850+ $1.65 x No. of Staff
Watson's
( 1st ~3rd Year ) = $252 + $906 x No. of Staff
( 4th Year & After ) = $906 x No. of Staff
Bonaqua's
( 1st ~3rd Year ) = $543 + $412 x No. of Staff
( 4th Year & After ) = $412 x No. of Staff

Appendix A
Cost of Commercial Tap Water Supply
Data from Water Services Dept. indicates that Tap Water costs $4.58 / m3 plus a sewage surcharge of $1.71 / m3,
i.e. a total of $6.29 / m3. Since 1 m3 = 1,000 liters and 5 gallons = 18.9 liters, therefore a bottle of 5-gallon tap
water costs ( $6.29 x 18.9 / 1,000 ), i.e. $0.12
