Water Management Programs

The ultimate goal of a Water Management Program is to control the growth and survival of waterborne pathogens such as Legionella, and to control epidemic in the facility.

Based on our years of experience in Water Management, we have developed a program that ensures that you are not only compliant to the authoritative agencies that are checking for these programs, but are also successful in managing the potential for waterborne pathogens that can proliferate in your water systems.  A complete Water Management Program will include the following Key Components:

The Precept Water Safety Plan

  • Hazard Analysis and System ID
  • Program Policies
  • Customized Standard Operating Procedures
  • Preventative Maintenance Schedules
  • Corrective Actions
  • Process Flow Diagrams

Precept Program Verification

  • Measurement of Compliance to your Program
  • Plan Modifications
  • Upcoming task Plan

Precept Analytical Validation

  • Bacteria Analytical
  • Chemical Analytical
  • Primary Disinfection Validation
  • Secondary Disinfection Validation

Precept Environmental specializes in helping our customers develop, implement, and document all aspects of an ongoing Water Management Program that is customized for each facility.

Our programs exceed the criteria of the proposed ASHRAE Standard 188, “Prevention of Legionellosis Associated with Building Water Systems”, and also helps to meet expectations of other governing authorities such as Center for Medicare & Medicaid Services, Departments of Public Health, The Joint Commission and DNV-GL Healthcare surveys.

Waterborne Pathogens of Significance

Waterborne Pathogens of Significance

Waterborne pathogens are contaminants in water that can cause illness or disease.  The water we rely on for life can harbor bacteria, protozoa, and fungi that can cause illness when ingested, inhaled, or contacted.  Even though our municipal water supplies are treated with primary disinfectants such as chlorine, there are other factors that can contribute to the growth and survival of pathogens in the water, including flow dynamics, temperature, metallurgy, and even the presence or absence of other bacteria or Protozoa.

This is why engineered water systems, such as domestic hot water systems, industrial cooling systems, and decorative fountains are of such a concern.  Water used for daily activities such as showering, cleaning, cooling, and irrigating can present a hazard to the surrounding population, particularly to those with weakened immune systems.

In these types of engineered water systems, biofilms can form on the wetted surfaces.  A biofilm is a thin layer of organic matter that creates a complex nutrient source and environment for bacteria and protozoa to survive.  Biofilms can also isolate and protect bacteria from disinfectants.  In biofilms, bacteria have a much higher resistance to antimicrobials than if they are free in the water.  It is in these biofilms that many waterborne pathogens such as Legionella can grow and reproduce.

Program Verification

Program Validation

The Precept Management Plan is only the first step in effective pathogen control.  Equally important is the verification and documentation of results.  In order to establish program success, Precept offers a 3rd party Validation Process that is tailored to your program. We perform this in a way that measures facility compliance with your own individual plan, and offers advisement on plan adjustment for greater success, if necessary.

Our Validation Process evaluates the program success based on your desired compliance to the evaluation criteria.  It also measures your performance to goals.  Our Validation Process includes the following:

  • Onsite review of Operator's Manual and Log Sheet documentation
  • Review of any analytical results
  • Preparation for upcoming Utility Water Safety Plan tasks
  • Identification of changes to Log Sheets if necessary
  • Identification of changes to the existing Utility Water Safety Plan for improved results
  • Management Progress Report / Executive Summary of Validation results
