1 Ian Cleaver 8 th March 2012 AMP5 Lead Programme

2 Current NWL Performance Current Compliance Against 25µg/l : 99.8% Against 10µg/l : 99.6% NWL’s plan Short to medium term plans are for no deterioration, to remain 99% compliant across the organisation. The long term plan is to be 100% compliant by 2024, however to attain this level of compliance legislation will need to change as ownership of private side pipework remains with the customer.

3 AMP5 Lead Programme Why is NWL Replacing Lead? The health issue Lead is a cumulative poison and research has shown that exposure to it has been linked to reduced neurodevelopment in vulnerable groups. It affects the young <6yrs It affects unborn children Change in regulatory standard The current regulatory prescribed concentration or value (PCV) is set at 25µgl (measured at the customers tap). On the 25 th Dec 2013 this PCV drops to 10µg/l making compliance tougher moving forward

4 AMP5 Lead Programme The NWL response (working with the DWI). Identification of ‘hotspot’ areas against the new 10µg/l standard. Operational and enhanced water samples WQ zones and DMAs Current number of renewals on the project (north & south) 4300 Control Measures Orthophosphate dosing at treatment works. Policy Changes Renewal of communication pipes on samples >10µg/l April 2010 NWL changed its lead communication pipe renewal policy to match the upcoming 2013 change in standards.

5 AMP5 Lead Programme The NWL response (working with the DWI). Opportunistic lead replacement For the AMP5 period NWL are replacing in excess of 615km of mains across all operating areas. Communication pipes are replaced when this work is carried out. Working with Local Authorities and PCT’s Renewing lead comm. pipes when local authorities replace lead supply pipes in their housing stock. Working with PCT’s, this is an area open for discussion; how do we inform and educate our customers, without raising undue concern?
