Likely areas of questioning

In a three panel session, the MPs will also hear from academic and campaigner Peter Hammond, regulators Ofwat and Natural Resources Wales, before hearing from Dŵr Cymru’s Chief Executive, Chief Financial Officer and Managing Director of Wastewater Services.

Among other issues, the Committee will be interested in hearing what action Dŵr Cymru is now taking to prevent further sewage spills, whether the system of self-reporting is working appropriately and what powers regulators have in penalising water pollution events.

This is the third evidence session the Committee is holding in relation to its work on Water quality in Wales. In April, following the initial hearing, Committee Chair Stephen Crabb wrote to the Minister for Climate Change stressing the urgency that Wales’ ageing combined sewerage system must be replaced to avoid further sewage discharges.
