No-dig technology reduces risk of
lead in water
Specially developed ‘no-dig’ technology
reduces the risk of lead dissolving into
the water supply in older buildings
and homes by restoring – rather than
replacing – lead pipes, according to
Pipe Restoration Services.
Up to 40 per cent of properties in the
UK are supplied with water through lead
service pipes – the main contributor of
dissolved lead in drinking water. Houses
and buildings built before 1970 are most
likely to have lead pipes. The legal limit
of lead in drinking water was reduced
from 25 to 10 micrograms per litre in
2013. However, in some parts of the UK,
the new standard is still not being met.
Lead is a cumulative poison, and
children are particularly vulnerable
as it affects both their physical and
intellectual development. Traditional
solutions such as phosphate dosing
and the replacement of lead pipes have
proven costly and disruptive. Estimates
put the cost of replacing all lead pipes
in the UK at between £8bn and £10bn.
ePIPE technology from Pipe Restoration
Services minimises disruption to
existing plumbing and reduces the time
involved. The ePIPE process uses a
lining material with a short two-hour
cure time, resulting in a quick return
to normal service. Special adaptors for
internal and external stop taps provide
access to the ends of the pipe without
the need to cut into it.
The ePIPE coating goes beyond legal
lead limits after application and is
claimed to be the first lining material
and process of its kind to meet the
stringent requirements of both the Water
Regulatory Advisory Scheme (WRAS)
and the Drinking Water Inspectorate
(DWI) for use in all public water supplies.
Approval means the lining process can
be used on any water company or
privately owned water services and
internal pipework to address lead
contamination issues and repair leaks.
There is no lead in water when it leaves
the water treatment works. However,
lead can be picked up by the water
if the service pipe is made of lead,
or if internal lead pipework and lead-
based soldered pipe joints are present.
More than half of UK families with
children under 16 live in homes built
before 1970, according to research into
drinking water habits. The majority (90
per cent) of those questioned said their
children drank from the kitchen cold tap
on a daily basis, yet 34 per cent were
unaware what their pipes were made of.
Tony Hanks from Pipe Restoration
Services commented, “The problem of
lead in water has not gone away and
the recommended solutions are too
costly and disruptive. Our goal is to
tackle the issue head on and go beyond
lead compliance. We can offer property
owners a longer term, more sustainable
solution than either replacement or
dosing alone can provide.”
