Tyneside Water Main Cleaning

Our water mains cleaning programme of works has been ongoing now for five years and to date, we have achieved 221km of cleaning works to our mains. There are a number of pipe sections that we still need to clean, with a total length of 9.0km. We are starting this work in August 2018 and anticipate completion in the Summer 2019.
