Represent the costs to provide 1 mgd of reclaimed water a distance of 5 miles. First value is the treatment cost and the seccond value is the<br />

total system cost in $/1000 gallons. (e.g. For Metals industries: the treatment costs are estimated to range from $1.70-$3.70/1000 gallons and<br />

the total system costs are estimated to range from $3.05-$5.00/1000 gallons.<br />

2 Refer to Table 10, Section 3.4.3 <strong>for</strong> relationship of reclaimed water classification to industry categories.<br />

3 This range reflects the cost to provide water to meet the water quality requirements <strong>for</strong> all uses of water by this industry sector. An accurate<br />

comparison to an industry's existing water supply costs must account <strong>for</strong> all onsite industry treatment system annualized capital and O&M<br />

costs.<br />
