This is the risk that the network or part of the network which underpins or complements the provision of the contracted services will be removed, not maintained or otherwise changed so as to prevent or frustrate the private party's ability to deliver the contracted services. This includes issues relating to the private party's access to and from the relevant government-controlled network. Where the private party relies on government inputs, complementary network risk includes risks relating to the availability and quality of the government inputs.
For example, a government agency controlling bulk water distribution may be unable to supply raw water to a public private partnership water treatment facility in the necessary quantity or quality.
