between the potable water and reclaimed water systems where potable water is used to
supplement a reclaimed water system.
13. Reclaimed water distribution lines shall be located 10 feet horizontally from and 18 inches below any
water line where practicable. Where these separation distances cannot be met, the piping and integrity
testing procedures shall meet water main standards in accordance with 15A NCAC 18C.
14. Reclaimed water distribution lines shall not be less than 100 feet from a well unless the piping and
integrity testing procedures meet water main standards in accordance with 15A NCAC 18C, but no
case shall they be less than 25 feet from a private well or 50 feet from a public well.
15. Reclaimed water distribution lines shall meet the separation distances to sewer lines in accordance

maximum concentration of 25 per 100 ml) or turbidity (instantaneous maximum of 10 NTU) be
exceeded, until such time that the problems associated with the treatment capability of the wastewater
treatment plant have been corrected. The wastewater in the 5-day upset basin shall be pumped back
to the treatment plant for re -treatment or treated in the 5-day upset basin prior to discharge to the two
(2) high -rate infiltration reclaimed utilization basins.
