Work to the well is due to start early this year and the well will reopen by the Spring.
Stephen Weeks, Kent Wildlife Trust’s Area Manager said: “We are delighted the council was able to provide the funding to repair the well.
“We’ve been working hard to identify the problem, find suitable contractors and gather estimates since it stopped flowing just over a year ago. It’s been a complex process but we’re thankful to have the funding in place to repair the well and have it open again to the public next year.
“We rely on funding and the hours of time that our volunteers donate each year to help us restore and protect the wildlife at this special site and we’re grateful for the support shown by the local community.”
Councillor Tim Valentine, cabinet member for the environment at the council, said: “We are delighted to allocate funding from our special projects fund to fix the artesian well in Oare Marshes. This fund provides up to £1 million every year to help pay for meaningful local projects that enhance our community.”
Councillor Mike Baldock, cabinet member for planning and heritage at the council, said: “We’re pleased to support the trust in their efforts to repair this historic well. It’s an important landmark for the area and it’s essential that we do all we can to preserve our local heritage.”
