Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, if he will make it his policy to require water companies to publish information on mains water pipes they own that are made of asbestos concrete; and if he will make a statement.

Water companies are required to risk assess their water supplies from source to tap including the mains network. Any network risks identified are programmed for replacement where necessary. Although it is well known that there are impacts from inhaling dry asbestos fibres, this is distinct from, and should not be confused with, ingestion of asbestos. The World Health Organisation assessment is that there is no consistent evidence of impact on human health through drinking water.

The government will not be making policy changes to require water companies to publish information on whether mains water pipes they own are made of asbestos concrete. The responsibility for maintaining assets lies with water companies.

OFWAT are driving company investment in the water sector, for example, in the current price control period, companies are investing £44 billion in the sector. In addition, Ofwat’s regime of company performance commitments promote investment in infrastructure.

According to the Consumer Council for Water (CCWater), whilst asbestos concrete pipework is not a significant concern for the thousands of consumers with complaints and enquiries that it supports each year, having a safe and reliable supply of tap water is of paramount importance for water consumers. CCWater expects water companies to provide clear information and reassurance to any consumer who raises questions or concerns with them about this.
