Water Supply and Usage

41th Annual Conference and Technology Exhibition

July 25-29, 2004


Presented By:

  • Tom Muratore, Executive Vice President, H2O Applied Technologies
  • Bob Loranger, Director, Facilities, TUFTS-New England Medical Center

Water, Water, Everywhere

  • Source Assessment
  • Treatment
  • Distribution
  • Conservation – Reduce Requirements

Source Assessment

  • Clean – know where your supply comes from
  • Quality – know the chemistry of the water
  • Reliable

– city based

- non-potable well



  • Potable: Chlorine, Chlorine Dioxide, Softener
  • Plant
    • Boiler
    • Cooling Tower
  • Hi-Purity – DI/Reverse Osmosis

- Central Sterile, OR, Research, Dialysis



  • Emergency – Are Plans in Place?
  • Disaster Preparation – Alternate supply,

domestic support, 18-24 hr backup

  • Mitigation
  • Recovery – know how systems will react when water supply comes back

Water Conservation

  • Facility Type Assessment
  • Benchmark Facility
  • Mass Balance
  • Conservation Plan

Water Balance: Hospitals & Research Facilities

Domestic: 25%

(10 million gals/yr)

Non-Domestic: 75%

(30 million gals/yr)

Cooling Towers


Food Services (Kitchen)

Operating Room

Sterile Processing (Autoclaves)

Radiology (Film Proc)

Analytical Labs

Pure Water Systems (RO/Stills)

Medical Air/Vacuum





Typical Water Saving Opportunity = A 25% Reduction


Why Water Conservation?

  • Wide range of water-using equipment in hospitals
  • Relatively easy to improve equipment efficiency
  • Excellent savings

What Water Conservation Is NOT

  • “Black Box”
  • Off-the-shelf solution
  • Limited to bathrooms

What Is Water Conservation?

  • Reduce, Reuse, Recycle, Replace
    • Reduceflow or frequency
    • Replace with water-efficient models
    • Reuse once-through water
  • Proven method to reduce operating expenses
    • Most solutions based on:
      • Simple engineering principles
      • Existing equipment specs/plumbing code
      • Off-the-shelf retrofits
engineered products systems
Engineered Products & Systems

Water Reuse

Reverse Osmosis Units


Water for Injection

Air Handling Unit Condensate

Domestic Water Reduction




Water Supply/System Use Analysis

Cooling Towers

Condenser Water

Chilled Water

Non-Potable Supply


Steam System

Non-Domestic Water Reduction

Central Sterile Equipment

Vacuum Pumps/Air Compressors

Radiology Equipment

Radiation Oncology

Operating Room Equipment

Ambulatory Surgery

Food Service Area

Refrigeration Equipment

Bio Reactors

Analytical/Lab Equipment

Instrument Washers

Cage/Cart Washers


Boiler Blowdown


Ways to Reduce Water Usage







  • H2O Applied Technologies has conducted engineering audits at hundreds of Healthcare facilities, resulting in a comprehensive Benchmarking study
  • The study with data from over 250 hospitals was presented at the 39th Annual ASHE Conference & Technology Exhibition, July 2002
  • This standard is used to show facilities where their water use should be, based on size and shape, and what opportunities exists to bring them in line with ‘best practices’ in water conservation.
  • This study is available upon request from H2O Applied Technologies

Water Use Profile Impact on Best Practice Factors

  • Type of Facility ( Specialty)

-Major Teaching with Research

- Major Teaching Hospital

- City Based General Hospital

- Community Based General

  • Regional Weather Impact
  • Local Steam, Chilled Water
  • Demographics
conservation opportunities
Conservation Opportunities
  • Domestic
    • Replace 3.5 gpf with 1.6 gpf in HT Areas
    • Reduce sink flow
    • Repair leaky fixtures
    • Waterless Urinals
    • Replace old shower heads
  • Process Equipment
    • Replace water cooled equipment
    • Use alternate source of water for cooling
    • Recover waste water and reuse
    • Make water using equipment more efficient
conservation opportunities1
Conservation Opportunities
  • Plant Operations
    • Install non-potable well
    • Reuse CT/Boiler Blowdown
    • Zero Landscaping
    • Recover condensate and reuse
    • Eliminate water-cooled equipment
  • Reduce Consumption by 30%
    • Benchmark
    • Set Goal
    • Develop WCM Plan
    • Implement Plan

Why Water Conservation?

  • Wide range of water-using equipment in hospitals
  • Relatively easy to improve equipment efficiency
  • Excellent savings
facility manager s perspective
Facility Manager’s Perspective

Motivation -- what is our incentive?

Understanding -- where is water used?

Who cares?

Who has the time?

Where do we get the funds to implement?

facility manager s perspective motivation
Facility Manager’s Perspective: Motivation

A painless way to reduce usage and costs

-- no staff reductions

-- no reduction in material/service

Sustainable Savings

Third party can do the work – Facility Manager can take the credit

No need to divert staff from more important things

facility manager s perspective understanding
Facility Manager’s Perspective: Understanding:
  • Where is the Opportunity?
    • The “no brainers” showers, toilets, faucets - been there, done that
    • Toilets, etc don’t excite the CFO
    • Process equipment
  • Who controls the equipment?
  • How can we effect change?
  • No matter what your location, water rates are increasing and supplies becoming an issue
facility manager s perspective who cares
Facility Manager’s Perspective: Who Cares?

Answer: No one.

New Question: How do we get the CFO to care?

New Answer: 40% ROI or

operating expense reduction without a capital investment

facility manager s perspective who has the time
Facility Manager’s Perspective: Who has the Time?

My staff is too busy complying with the new Environment of Care standards and continuing operations.


Let someone else do the work

(corollary: it’s ok to let other people make money if your facility benefits, too)

facility manager s perspective where do we get the funds
Facility Manager’s Perspective: Where Do We Get the Funds?

Capital Dollars are scarce and must compete against program

Operating budgets are getting cut

Off-balance sheet financing (i.e. pay back installed conservation measures from savings)

creative new funding approach
Creative NEW Funding Approach
  • Utility Expense Reduction Program
  • Requires NO Capital
  • Treated as an Operating Expense
  • 5-Year Program
  • Savings Fund Program
  • M&V Every Year
