SHOPPERS have been given an insight into work to repair 30 miles of water mains in Huddersfield town centre.
Yorkshire Water has begun a major programme to replace pipes dating back 150 years.
The project got under way last week, with the first phase involving roadworks in Kirkgate and Westgate.
Yorkshire Water officials were at the Kingsgate centre to explain the scheme to shoppers, traders and other town centre businesses.
The company said the improvement work - replacing old iron pipes with plastic ones - was needed to make sure drinking water continued to meet strict standards.
The work involves "pipe- bursting" - feeding new pipes through existing ones, then expanding them to break the old pipes apart.
The technique - which can be used where there are no other utility pipes or cables nearby - avoids the need to dig trenches to remove lengths of pipe and lay new ones.
Caroline Atkins, communications adviser for Yorkshire Water, said people and businesses would be regularly updated on progress.
She said it was hoped to keep disruption to a minimum.
The work would need temporary traffic lights at various times, but pedestrian access to town centre premises would not be affected, said Ms Atkins.
