    The 10News article, above, cites a lowball cost of reused water for the Orange County Water District that is in need of a critical review. The water in question is 70.000 acre feet per year of treated, reused water that is injected into their aquifer, half of which is used as a salinity barrier, and half for aquifer recharge. Granted that the determination of water cost is complicated in such a system, allowance for treatment, delivery, injection, recovery and distribution should be included.

    The San Diego County Water Authority staff reported on “Unit Cost of New Local Water Supply Alternatives” at the Authority’s board meeting on September 15, 2010.The report attributes to the Orange County reuse program a cost of $887 per acre foot plus recovery cost of $412/AF = $1299 (2010 dollars). It is not clear whether the additional costs of final treatment and delivery are included in this number.

    The City of San Diego potable reuse program, also cited in the Authority’s report, is much more expensive, as well as containing a much different (and problematic?) reservoir sequestration plan.
