Domestic Water Disinfection

When industrial or domestic water systems become excessively contaminated, urgent and documented corrective actions may be necessary.

Background
Home→Facility Support & Disinfection Services→Domestic Water Disinfection

If this type of emergency remediation is necessary, Precept Environmental can deploy a disinfection and remediation team to discreetly and effectively reestablish control of facility systems and associated equipment.

Not all disinfection procedures are equally effective.
Insufficient protocols can sometimes cause more harm than good.

Precept advisors will help management determine what corrective action protocols may best suit the situation. All of our disinfection procedures are derived from standardized practices as prescribed by governing authorities such as ANSI, AWWA, OSHA, ASHRAE, and the CTI, and can be modified to minimize any facility downtime.

Client Confidentiality

Client confidentiality is of utmost importance to Precept and our clients. All services, results, and documentation will be property of the client, and kept proprietary by Precept Environmental.

Who We Are

After over a decade of experience in water management and chemical water treatment, Precept Environmental, Inc. was founded in 2008 by Britt Rodgers and Johanna Astaire with the goal of providing customers unbiased solutions in water management. They were dedicated to building a business that was based purely on consulting and support services, free of any ties to chemical or equipment solutions, or an in-house laboratory. By prioritizing our customers’ best interests, we have earned their trust and loyalty. These founding goals remain deeply rooted in our business model and will continue to dictate how we conduct business.

No, but you must Validate that your plan is effective, and the only way to know for certain is to actually test the water. Testing the water may be more important for healthcare facilities providing inpatient services to people with an increased risk for Legionnaires’ disease; or when there is difficulty maintaining control limits, such as disinfectant residuals, in the building water system.

Precept always recommends utilizing the culture method for Legionella bacteria, performed by a CDC Elite lab, which takes 7-14 days. Additionally, the CDC prefers this method for evaluating growth trends. Alternative testing methods that may promise quick results are often a waste of time and money, as they need to be validated against a standard method.

Legionella bacteria is difficult to grow and isolate in an environmental laboratory. Only a CDC Elite lab should be considered to ensure accurate results from your water samples. The prescribed culture time allows for slower growing Legionella species to be observed and avoid false negative results; therefore, faster results are not achievable without compromising accuracy.

The CDC Toolkit for Developing a Water Management Program lists two options for Validating a Water Management Program: 1) Environmental testing for Legionella, 2) Checking disinfectant residuals, such as chlorine, in the building water system. 
If a “quick result” test is offered, it often will need to be validated against the traditional culture method anyway, which can lead to ambiguity in how to respond to unfavorable results.

Precept recommends that there be a plan in place before testing is done. This enables the Water Safety Team to adequately prepare for any outcome. Corrective actions should be specific to your facility and performed according to your Water Management Plan. If you don't have a plan in place, Precept can assist with recommendations.
