Action is being taken to remove Travellers from a piece of open land in Holland-on-Sea.
The group of three caravans and vehicles turned up in Sladburys Lane opposite Happy Valley Bowls Club on Saturday evening.
The issue was reported to Tendring District Council and the duty officer visited the site on Sunday.
He was told that the group’s intention was to stay there until Easter Monday.
The officer noted issues of toilet waste being emptied into Picker’s Ditch and the Essex County Traveller Unit has been informed of the situation.
Nigel Brown, Tendring District Council’s Communications Manager, said that the unit attended Sladburys Lane and served the group with a Direction to Leave.
“The Direction to Leave gives them 24 hours to move on,” he added.
“If they do not move on then we hope that the matter will go through the courts at the end of the week to get an Order to evict them.”
