Cherwell District Council and South Northamptonshire Council are now sharing environmental services, reducing the number of senior managers and saving £200,000 a year.
The new shared management structure follows the implementation of shared environmental services late last year, which included covered bring banks, bin deliveries, bulky waste and commercial waste.
Cherwell's lead member for clean and green issues, Cllr Nigel Morris, said: ‘We've gone a long way down the road of sharing structures and services between the two councils. But we can do more - so it makes sense to combine our waste collection operations in a move that will see overall savings for the two council of more than £200k a year.’
The structure has resulted in the reduction of five management posts - two through voluntary redundancy and three by not replacing vacant posts.
