Corrosion attacks potable water systems in a variety of ways, from the leaching of substances into the water system to the corrosion of the physical assets.

Internal Corrosion in Water Distribution Systems  

The Challenge:  Release of dissolved and particulate lead and copper corrosion products in potable water piping has been a concern in the U.S for several decades.  Lead can cause damage to the brain and kidneys and can interfere with the production of red blood cells that carry oxygen to all parts of the body.  Copper is an essential nutrient but elevated levels in drinking water have been shown to cause stomach and intestinal distress.

The Focus:  Since the promulgation of the Lead and Copper Rule, and initial optimization of corrosion control, systems have faced the ongoing challenge of continuing to maintain optimal corrosion control while making necessary adjustments to treatment processes or system operations to comply with other regulatory requirements.

Corrosion of Physical Assets
The Challenge:  ACE International, a leader in the field of corrosion, estimates that the annual direct cost of metallic corrosion in the water and waste water industry is approximately $58.5 billion nationwide. Corrosion is a natural process, which converts a refined metal to a more stable form, such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually metals) by chemical reaction with their environment. As immortalized by Neil Young, “Rust Never Sleeps”.

The Focus:  Although the science and application of metallic corrosion management has improved over the past several decades, there remains a significant opportunity to mitigate corrosion damage by increasing corrosion awareness amongst decision makers; identifying and avoiding the potential for corrosion during project design; actively monitoring for corrosion during asset life, and repairing assets and mitigating against further damage when corrosion is discovered.

Agenda:

7:30AM – 8:00AM            Registration, Coffee and Pastries
