Given the benefit to public health, we believe
that we have a role to play in addressing the
issue of lead supply pipes. However, we do
not propose to replace all lead pipes as we
are not legally responsible for customers’
supply pipes. This strategic response will
involve four programmes to mitigate the risks
of lead pipes replacement:
• Replacement of all communication and
lead supply pipes by Welsh Water where
higher than normal lead sample readings
have been identified (even though these
will typically still meet all the required
health standards);
• Replacement of lead supply pipes
amongst vulnerable customer groups,
through the Welsh Governments ‘Arbed’
and ‘Nest’ schemes for households with
expectant mothers and children under 6;
• Replacement of lead supply pipes by
Welsh Water when found during meter
installations; and
• Offering grants to all customers who
approach Welsh Water if they find lead
pipes.
If Welsh Government placed a requirement
on Welsh Water to replace of all lead supply
pipes, it would require a change in legislation
and would cost an estimated £650m.
