LAS VEGAS–(BUSINESS WIRE)–Pipe Restoration Technologies, LLC (PRT), makers of the ePIPE®,
Lead-Free, Leak-Free™ and LeadSmart® product lines, announced that it
has received three Notices of Allowances from the U.S. patent office for
the company’s patent application numbers 15/254324, 15/164268 and
15/449454. These allowances cover the ePIPE process in providing methods
of placing a protective barrier coating for leak sealing protection and
lead (Pb) reduction in underground drinking water pipes.
Pipes protected with ePIPE reduce the leaching of toxic lead and copper
into drinking water to well below U.S. Environmental Protection Agency
(EPA) and World Health Organization (WHO) cut-off levels. Pipes from as
small as 1/2” in diameter can be protected in-place using the patented
ePIPE system and materials. The protection of lead
service lines (LSLs) can be completed under four hours per line and
often with no excavation on the home owner’s property.
These patent grants and allowances adds to the company’s patent
portfolio of over 20 issued patents in various countries, including the
Water Research Foundation Makes Recommendation
Water Research Foundation Report 4351 released March 2017, recommends
coating LSLs be considered an option to replacement. This study was
jointly funded by the Water Research Foundation (WRF) and the EPA.
Protecting LSLs in-place in Greater London, UK.
The ePIPE solution has been part of one of the world’s largest lead pipe
remediation programs involving some 30,000 lead water supply pipes. LSLs
run underground from the water main to the curb stop tap (valve) at each
property; that same pipe may also run to the supply tap inside a house.
ePIPE approved to US NSF Std. 61 and UK’s DWI Reg 31 (4)(a) with a 2
hour return to service.
ePIPE’s epoxy coating is one of the fastest NSF Standard 61 and DWI
Regulation 31 approved return-to-service epoxy
lining products in the world. ePIPE is engineered and patented for
protecting drinking water pipes from leaks and bringing lead leaching
into compliance to the stringent WHO’s cut off level of 10 ppb (µg/l).
About ePIPE® and LeadSmart®
The patented ePIPE process involves restoring pipes in-place, with an
application of an epoxy barrier coating resulting in a restored epoxy
lined piping system. The process provides a solution for slab leaks,
pinhole leaks, and the reduction of lead leaching from lead pipes and
lead contributors. LeadSmart is an on-site lead testing and lead
remediation service, leading to a property being LeadSmart Certified.
