Broome County will look into taking over the Binghamton Johnson City joint sewage treatment plant.
On Thursday night, by a vote of 17 to 1, the Legislature agreed to pay an engineering firm $65,000 to conduct a study.
It wants to find out if a takeover is possible and in the county's best interests.
That study is expected to take a couple of months.
Some legislators say wastewater can best be handled by the county.
"It really is a county problem, because we've had some initiatives we've had to turn away because we didn't have the capacity. If you know, we need to put our heads together and our resources together and come up with a county wide solution that's going to put Broome County in a better position to attract and retain jobs," said legislative chairman Dan Schofield.
Schofield says the Legislature had a study done called the Hudson Report in 2002.
That report concluded there was justification for direct involvement of the county in the management of wastewater management.
