Environmental standards and assurance

It's important that we set and follow the best standards in all our environmental actions and processes, so we can make sure we're doing all we can to help reduce our carbon emissions and meet our environmental goals.

Assurance programmes

Our ongoing assurance programme across our Environmental Management System helps to support colleagues across the business with issues on sites and managing their risks and compliance obligations, as well as driving efficiencies.

First line assurance is carried out by our operational teams every week. This allows timely interventions to be made and helps the teams improve on day-to-day performance. Our Standards and Assurance teams then analyse for trends and build this into focussed assurance visits and improvement activities.



Key facts

*(based on cat 1-3 pollutions submitted to OFWAT for our PR19 Fast track plan, 2010-11 there were 37.3 pollution incidents per 10,000km of sewer network, compared to 27.41 in 2018-19)

Benchmarking our environmental management system

We're determined to be an indsutry leader in everything we do. That requires constant evaluation and innovation. Part of that process involves benchmarking against other organisations, how they perform, and what we can learn from others to push ourselves further.
