East Midlands Airport says it is fully aware the wind turbines at Spondon could cause disturbance to its radar system.
Severn Trent said the two 130-metre structures, in Megaloughton Lane, will not be fully operational "until later this year".
The airport and Severn Trent both said they are working together on installing new technology to get rid of the problem.
The Airport said the turbines are located in a "sensitive area" so when the turbines turn it appears as an unidentified object on the air traffic control display.
A spokesman for the airport said: "East Midlands Airport has been working alongside Severn Trent for a number of years to ensure that the turbines can operate safely.
"At present the airport is working with Severn Trent Water and a technology provider to install radar technology that will mitigate any effect that their wind turbines will have on the radar at the airport.
"Safety at East Midlands Airport is paramount and will not be compromised."
The turbines will produce 10,000 megawatts of electricity, which is the equivalent of supplying about 3,000 homes with power.
A spokesman for Severn Trent said: "This equipment is needed to maintain the safe operation of the airport when the wind turbines are operating."
