PPPs are only one of several tools available to municipalities to deliver infrastructure services in a more efficient and fiscally effective manner and the structure of a PPP used for a specific project is flexible. Each approach has different characteristics and priorities. Figure 1 shows the relationship between a few of the more common structures. For the purposes of this Municipal PPP Framework, PPP includes different approaches to private entities partnering with municipal authorities to deliver infrastructure services, with the private sector making a long-term commitment and taking significant project risks. A municipal PPP is a PPP where the government entity is a municipal or local government body and where the public asset or service is a municipal asset or service.
