In January 2017, Ian McAulay met with Ofwat to discuss the issues we were facing, after the Environment Agency started an investigation into a small number of our wastewater treatment sites.
In June 2017, our regulator Ofwat started an investigation into possible breaches of licence conditions and our statutory reporting obligations relating to the management and operation of our wastewater treatment works.
We immediately started our own internal review and discovered a problem with sampling processes at some of our sites which meant that we needed to restate our wastewater performance for the period 2010–17. The findings of our own review have been shared with our regulators.
In October 2019, Ofwat’s investigation resulted in a notice to take enforcement action against us.
