A Technician using a hydrant

To deliver high-quality drinking water to you, 24/7, we have to keep our systems in tip-top condition. To achieve this we carry out a variety of maintenance jobs.

Mains water flushing

One of these is to periodically flush some of our water mains, particularly if we believe natural iron sediments have built up inside them.

To find out if we’re planning to flush the mains in your street, check out our maintenance and improvements section In Your Area.
