Location / involves a tunnel and flume. The tunnel is estimated to have a first cost of $200,000 and is assumed to be permanent. Its annual upkeep costs are estimated as $500. The flume will cost $90,000, has an estimated life of 20 years, and is expected to have annual maintenance costs of $2,000. Location K involves a steel pipe line and several miles of concrete- lined earth canal. The pipeline has an estimated first cost of $70.090. an estimated life of 50 years, and an estimated annual maintenance cost of $700. The earth canal will cost $80,000 and is assumed to be permanent. During the first 5 years it is estimated that maintenance on the earth canal will be $5,000 a year; thereafter, it is estimated as $1,000 a year.
