Lease 

In a lease structure, the government grants a leasehold interest in some or all of the assets (usually the entire existing system) with the requirement that the private firm will operate and maintain them pursuant to a lease agreement. The private firm charges the utility an agreedupon amount for providing the service. Investments in new or expanded facilities would still be the responsibility of the public owner of the assets, while the private lessee would be responsible for repairs and rehabilitation as needed of the leased property. Meter reading, revenue billing and collection may be contracted to the private firm, but rate setting and responsibility for overall financial results would still be the purview of the public owner. In some cases, incentive payment plans with the private lessee may be used to try to improve financial results. In the U.S. it is not unusual for convention centers, sports facilities and entertainment venues to be operated in this manner.
