Conjunctive Reclaimed Water
Utilization System
Lee County
In accordance with your permit minor modification request received July 1, 2011, we are
forwarding herewith Permit No. WQ0020248 dated July 27, 2011, to the City of Sanford for the
construction and continued operation of the subject wastewater treatment and conjunctive reclaimed water
utilization facilities.
The modifications to the subject permit are as follows:
• The permit description has been revised to authorize the use of reclaimed water onsite for
dust control and soil compaction during wastewater treatment plant construction activities.
• Condition IH.13. lists requirements for the use of reclaimed water for dust control and soil
compaction during construction activities.
• Condition IV.5. requires the Permittee to track the estimated monthly totals of reclaimed
water distributed for onsite construction activities.
• Attachment B (PP1 002) requires the Permittee to estimate the flow of reclaimed water used
for onsite construction activities on days when reclaimed water is distributed for this
purpose.
• Rule citations have been updated throughout the permit to reference the new 15A NCAC
02U rules that became effective June 18, 2011.
Please note that a permitted program for bulk distribution of reclaimed water for off -site users is
not being approved at this time. Approval of a permanent bulk distribution program will require a future
permit modification upon documentation of: a flow meter for continuous recording of bulk reclaimed
water distributed; a description of the certification program to be used for approving off -site users of bulk
reclaimed water; and examples of training materials to be used for off -site users of bulk reclaimed water.
