Capital cost estimates are presented using <br />an inflation factor of 3%. For comparison, Table 7 presents the estimated current replacement <br />value of the regional wastewater system. <br />Total projected capital cost for 2016 to 2040 is estimated at $5 billion. On an annual spending <br />basis, with adjustment for inflation, this equals the total level of spending from 1970 to 2015. <br />Projected capital investment by type of infrastructure is 64% interceptors and 36% treatment. <br />Investment by objective is approximately 80% for asset preservation, 10% for quality <br />improvement, and 10% for growth. These costs exclude costs associated with potential future <br />regulatory requirements, which are discussed later. <br />Capital improvements for the regional wastewater system are primarily financed by Metropolitan <br />Council wastewater bonds and Minnesota Public Facilities Authority loans. Bonds and loans <br />are repaid using wastewater fees. <br />38 <br />
