Minimal disruption water main renewal technologies offer opportunities to extend the life of existing infrastructure with less cost and reduced public inconvenience compared to traditional replacement options. These renewal options cover a wide range of applications, but it is important to understand the project requirements to select an appropriate solution. This paper will provide an overview of the information required to determine which technologies can provide the best option for water main renovation. This includes the existing condition of the host pipe, the current operating conditions, and the level of service that the renovated pipe is expected to provide. In the industry, there are a number of terms used to describe liners. They can be called structural or semi-structural, or interactive or independent, depending on the classification system used. This paper reviews the terminologies, and how they correspond to each other. Understanding these concepts is a requirement in liner selection. This paper will also present brief case studies on two projects completed in 2007 in North America. The case studies deal with polyethylene liners ranging from 12 inches to 24 inches in diameter, installed using two different cross-section-modified techniques, providing interactive and independent liners.
