Since 1990, water privatization, which relates to turning over some or all of the assets of a public system to a private company, has been growing rapidly throughout the world and some in North America. Although privatization can be beneficial in some circumstances, it is important that, at the very least, government oversight is maintained to protect the public interest. There is a growing body of resources to leverage to understand the pros and cons of privatization (called a public-private partnership (PPP)).
The three most common forms of PPPs, in the order of increasing responsibilities for the private partner, are:
- A management contract, under which the private operator is only responsible for running the system, in exchange for a fee that is to some extent performance-related. Investment is financed and carried out by the public sector. The duration is typically 4–7 years.
- A lease contract, under which assets are leased to the private operator who receives a share of revenues. He thus typically bears a higher commercial risk than under a management contract. Investment is fully or mostly financed and carried out by the public sector. The duration is typically 10–15 years.
- A mixed-ownership company in which a private investor takes a minority share in a water company with full management responsibility vested in the private partner.
A concession, under which the private operator is responsible for running the entire system. Investment is mostly or fully financed and carried out by the private operator. The duration is typically 20–30 years.
