McDaniel said the costs in the projected $55-million effort could fluctuate because of the architecture and condition of the water distribution system. The estimated cost per line is $3,670, according to a city document. Of the $55 million, about $1.5 million will go toward administration and logistics, according to the city, which said personnel costs are estimated at $900,000 and operations costs are projected to be $600,000. According to the city, the bulk of the cost — $36 million — will go toward the labor and about $9.7 million will go toward the materials.
