A higher than normal number of complaints was made after strong smells were experienced in the town last month, which were later traced to a fault in pipes at the site.
That sparked a meeting called by the site operators, Scottish Water, and the firm contracted to run the state-of-the-art facility, Veolia Water.
Community representatives were invited to discuss the way local people are informed of any problems at the treatment works with a Scottish Water representative attending last weeks meeting of the Lossiemouth Community Council.
As a result further meetings are to take place quarterly where concerns from the community can be aired and new proposals for communicating with local people will be made.
Following the issues reported in April a temporary repair was made at the site with the promise of a permanent repair being made.
That will be carried out on Friday with a Scottish Water spokesman saying: “I would like to advise of some essential maintenance work at Lossiemouth wastewater treatment works.
”During the morning of Friday May 30, Veolia Water will be replacing a section of damaged odour ductwork within the site.
”This section was a contributory factor to a cluster of odour complaints during April this year.
”A mitigation measure to minimise offsite impact will see odorous air being diverted to an alternative treatment process.
“We anticipate that the repair work will be completed within around three hours. We would like to apologise for any inconvenience that may arise from this essential work.”
