Neighbours living on a Bilsthorpe street fear flood work further up stream could now put their homes at greater risk.
Those on Mickledale Close are worried that Rainworth Water, a stream that runs directly behind their homes, could be more prone to bursting its banks because of the work to protect Rainworth.
More than £250,000 has been invested to curb the rising waters affecting parts of Rainworth. The recently-completed work carried out by Nottinghamshire County Council will see excess water being stored in tanks during heavy rainfall, before being released downstream.
But with Rainworth Water already at risk from rising waters - sometimes leaving Mickledale Close under a foot of water and raw sewage - residents fear it will become a more regular occurrence.
Resident Don Smith said: “They’ve done this work at Rainworth, but nobody’s thought about where this water will go. If it rains excessively, they have an overflow and it will run into the stream at the bottom of our gardens.”
Harry Jenkins has lived on the street for nearly 40 years and is fighting an ongoing battle to find those who should be monitoring the waterway, with Nottinghamshire County Council and Newark and Sherwood District Council, along with Severn Trent Water denying responsibility.
“I’ve been touch with all of them and all that happens is that you get passed back and forward, and it’s getting worse,” he said. “There’s more water coming over than there used to be. “We’ve brought it to people’s attention but we’re not sure what else we can do.”
