HOSPITALS COST SAVING-
WATER EFFICIENCY
Hospitals are realizing water-utility costs savings by reducing water consumption. In
some cases, water-efficiency measures also reduce energy costs. Savings generally result from a combination of Behavioral
And Technological solutions.
Decrease consumption
Reduce energy cost
Water use per capita ranges from 40
gallons per day to 350 gallons per day,
depending on such factors as
• Geographical Location;
• Services Provided;
• Size, Age, And Type Of Buildings;
• And Water-use Equipment And
Practices.

Getting started....
• Establishing a Comprehensive Water Management Program
• It involves the participation of the local utility and a wide variety of stakeholders, both inside and outside of the hospital.
• Decision-makers must be particularly sensitive to issues of infection control and the potential for contamination of portable water supplies.

Water Conservation Programs
Hospitals that have conducted
successful water use reduction
programs have been able to
reduce water use by
approximately 20 to 30%.
![Page 12: Impact of water cost in hospitals by D Gurbir Singh](https://reader034.vdocuments.net/reader034/viewer/2022051301/5a6d45987f8b9ae5418b519f/html5/thumbnails/12.jpg)
AREAS OF SAVINGS
1. Small behavioral adjustments
2. Operations and maintenance
fixes that can result in major
savings.
3. Older buildings typically
squander a tremendous amount
of sanitary water(For example,
one leaking toilet alone can
waste more than 50 gallons of
water every day; one dripping
faucet or showerhead can waste
up to 1,000 gallons per week.)
4. Hospitals can realize significant
savings by upgrading toilet,
shower, and faucet
technologies.
5. The HVAC system
• Consuming less hot water
reduces the energy needed to
heat water in boilers.
• Reducing the cooling load on a
system with a cooling tower
decreases the need for
heat rejection.
• Optimizing the controls for a
chilled water plant can save
both water and energy.

Implementation of Water
Conservation Changes
Audit current water use.
Identify water
conservation
opportunities
Determine cost
of opportunities and potential return
on investme
nt
Prioritize water
conservation
opportunities.
Develop a
phased plan that fits your budget.
Obtain funding(revise plan, if
necessary).
Implement plan.
Measure and
document
success.

Water Conservation
Opportunities
The Basics
• EMPLOYEE AWARENESS
•
• INCREASE PATIENT AND VISITOR AWARENESS
• LOCATE AND CORRECT DRIPS, LEAKS, AND UNNECESSARY FLOWS in bathrooms, laundry, kitchen, labs, etc.
• REPAIR/ADJUST FLUSH MECHANISMS on toilets so that they work as designed.
• IRRIGATE GROUNDS AND WASH VEHICLES LESS OFTEN.

Taski Fresh Clean Urinal Systems
* These Taski Fresh and Clean Urinal screens requires no flushings and one
screen costs Rs 250/ and lasts for 4 weeks thus saving lots of water.

Process Equipment
• General. As appliances andequipment wear out, replace with aircooled or water-saving models.
• Steam traps.
• Sterilization equipment. – Install steam condensate temping
systems
– Replace water-induced vacuumdevices on sterilizers with electricpumps
• Film processors.
• Refrigeration equipment.
![Page 20: Impact of water cost in hospitals by D Gurbir Singh](https://reader034.vdocuments.net/reader034/viewer/2022051301/5a6d45987f8b9ae5418b519f/html5/thumbnails/20.jpg)
Water Reuse
• Radiation therapy linear accelerator(creates high-energy radiation to treat cancers). Water can be taken from the reject side of the linear accelerator heat exchangers and pumped to the facility’s cooling towers and reused for evaporative cooling.
• Reverse osmosis (RO). Reject water produced in the RO process can be reclaimed for non-miscellaneous potable water use or in the cooling towers.

Water Supply/Systems
• Water pressure. Install pressure-reducing valves where system pressure is higher than 60 psi.
• Cooling towers. – Reduce excessive blow down. Operate cooling towers near
manufacturer recommended level of total dissolved solids (TDS).
– Consider using ozone as a cooling tower treatment to reduce water used for make-up.
• Boiler. Return steam condensate to boiler for reuse.
• Sprinklers. – Minimize water use for irrigation (e.g., adjust repair sprinklers,
install wet weather shutoff and/or soil moisture controllers).
– Investigate sources of used water.

Kitchen
• Dish washing.
– Wash full loads only.
• Other.
– Turn off the continuous flow used to clean the
drain trays of the coffee/soda beverage island
(only clean the trays as needed).

Laundry
• Washers.
– Reprogram machines to eliminate additional
rinse cycles, if possible and not restricted by
the health department.
– Wash full loads only or reduce water levels to
minimize water required per load of washing.
