Abstract: The value of existing assets has become a factor of special interest to the asset owners as outsourcing of maintenance duties has increased. The value of water and sewer systems should be assessed in order to follow up the development of the network's long-term condition during a maintenance partnership contract and to determine the optimal renovation timing and method. Many factors affect the condition of the network, which makes the determination of the service life difficult. The use of existing value assessment methods is also essential in order to assess the systems economically. However, the value should be addressed holistically instead of determining only the economic value of the system. In this paper, we provide a comprehensive discussion on the value assessment of the water and sewer systems. A method for assessing the development of value during maintenance or renovation contract is presented.
