An update on Coronavirus

Our teams have remained committed to supplying essential water and wastewater services during the pandemic. We care about keeping people safe, so we’ve made some changes to the way we work.

Some activities may take a little longer than before. We’re doing extra checks to protect our people before we start groundworks. Some of our colleagues are also still working from home. We’re grateful for your patience and support. You can help us by only chasing up applications if you really need to.
