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. proven costly and disruptive. Estimates put the cost of replacing all lead pipes in the UK at between £8bn and £10bn.

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.” Pipe restoration services – UK info@piperestorationservices.co.uk www.piperestorationservices.co.uk

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.

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
