The Whanganui District Council will meet in extraordinary session next Tuesday to adopt two parts of its 2016-17 Annual Plan.
It follows last week's milestone meeting when the council finally decided to go ahead with the build of a new wastewater treatment plant for the city.
But, in clearing the way for the project to move, staff will have to make changes to supporting information for the Annual Plan as well as the consultation documents that go with it.
Those two issues have been held over from the March 9 meeting, but it's the implications of the decision to rebuild the treatment plant that need tweaking
The revisions will also need to be written into the 2015-25 10-Year Plan.
