Work will begin in the New Year on a £500,000 project to connect Broughty Ferry Castle Museum to Scottish Water’s sewer network.
Upgrades will take 12 weeks and will require parts of the surrounding area to be fenced off from January 5.
The castle approach road will be closed and the nearby play park access point will be fenced off, although Broughty Ferry Castle Museum and all other entrances to the play park will remain open and accessible to the public.
The upgrade will ensure that waste from the castle and museum is taken and treated to the highest possible standard before being returned to the environment.
Scottish Water said it had arranged the works in liaison with SEPA, Dundee City Council and Leisure and Culture Dundee, which manages the castle.
Bosses hope that the timing of the works will “minimise inconvenience to members of the public”.
“Work of this nature is essential to ensure waste and sewage is treated to the highest possible standard and often requires excavations to access the sewer network,” said regional manager Ruaridh MacGregor.
“To continue meeting customer expectations it is important that we deliver investment to maintain our network.
“We do all we can to keep this to a minimum and have been liaising closely with our contractor and local partners to ensure this work is carried out with the least amount of disruption and at the most suitable time.
Chair of Leisure and Culture Dundee, Bob Duncan, said the upgrade to pipe work was “welcome”.
“This will provide a lasting improvement to the infrastructure at Broughty Castle Museum,” he said.
