Pipe Restoration Technologies, LLC, (PRT) today announced that it has been awarded US patent #8,524,320 for its innovative ePIPE® in-place lining technology, which reduces lead, from lead pipes and other in-line lead contributors from leaching into the drinking water supply. Using the ePIPE process, lead levels are reduced to below the World Health Organization’s (WHO) guidelines for lead of 10 ug/l (10ppb).

The patent, "Process for Coating the Interior Surface of Water Service Lines” was granted by the USPTO, which covers the in-place coating of lead pipes, curing the resin, in at least 1 hour and when cured reduces lead in the water supply to less than 10 ug/l (10 ppb). The process is completed to pipes “in-place” reducing the need for excessive digging or tearing up a buildings foundation or walls, as is common using conventional pipe replacement methods.

ePIPE protected pipes and fittings allow water suppliers to discontinue the use of lead inhibitors.

It is estimated that 25% of domestic dwellings in the EU have a lead pipe, either as a connection to the water main, or as part of the internal plumbing, or both, potentially putting 120 million people at risk from lead in drinking water within the EU.

An estimated 38 million properties in the US are affected by lead leaching into the water supply.

Lead is a cumulative poison, and exposure can affect nearly every system in the body. Children under 6 and pregnant women are the most susceptible to the negative health effects of lead exposure.

“With the application of our patented ePIPE technology we are contributing to a healthier delivery of drinking water especially to those most at risk to exposure to lead, children under 6 and expecting mothers”, says CEO, Larry Gillanders.

With the ePIPE product and process, water supply pipes can be restored “in-place” in a matter of a few hours per property.

“We have already completed lead reduction programs with several proactive Water Utilities and Housing Councils in the UK, and with the US Department of Defense in the United States. In all cases, after the ePIPE process, a first draw of standing water, tested at the kitchen tap for lead, was found to be in compliance with new WHO/EU guidelines”, added Larry.

Corresponding patent applications have also been filed in other countries including the European Union.
