New homes in a flood-hit Devon village have not been fitted with flood prevention measures by a developer, a council has said.
East Devon District Council said water collection tanks had been a condition of the planning permission as Wainhomes builds 50 homes in Feniton.
It said it was a "serious omission" and was considering enforcement action against the developer.
Wainhomes is yet to comment. The village has been flooded several times.
Resident Martin Smith said: "A tremendous downpour which lasted a very short time was enough to flood a number of houses."
Flood warden Jayne Blackmore said: "It's horrendous, every time we have heavy rain we are on tenterhooks, we don't sleep, it's very, very stressful."
The council said it had contacted the company verbally and in writing to "correct the omission as a matter of urgency".
It said: "The homes should not have been occupied until this condition had been fulfilled.
"Whilst the homes themselves may not be at risk, there is a very real danger that Wainhomes' failure to do this work could make the village more vulnerable to flooding as a result of the absence of the attenuation tanks."
