Reclaimed Water Utilization System
Durham County
Dear Mr. Pearce:
In accordance with your permit application request received March 3, 2008, we are forwarding
herewith Permit Number WQ0032821 dated March 14, 2008, to Durham County for the operation of the
subject reclaimed water utilization system. This permit approves the operation of a bulk reclaimed water
fill station with approved uses limited to uses identified in Attachment: Approved Bulk Fill Reclaimed
Water Uses.
Please note that the use of the reclaimed water for vehicle washing and pressure washing for
commercial users is only acceptable provided that both the UV disinfection and chlorination systems are
installed and operated properly to disinfect the reclaimed water. If the County wishes to pursue these
uses, they must demonstrate that dual disinfection by UV and chlorination or equal is present.
Educational requirements described in Condition IH.5 shall be developed and implemented prior
to distribution of reclaimed water for each type of use. Please note that educational material shall be
developed specific to each type of use and for various types of users if necessary. Educational material
must be available for review by the Division, upon request.
This permit shall be effective from the date of issuance until February 28, 2013, and shall be
subject to the conditions and limitations as specified therein. Please pay particular attention to the
monitoring requirements in this permit. Failure to establish an adequate system for collecting and
maintaining the required operational information will result in future compliance problems. Of special
interest are the following:
Condition 11.6 — Bulk reclaimed water compliance boundary condition,
Condition 111.5 — Requirements for proper use of bulk reclaimed water,
Condition IV.5 — Record keeping requirements for bulk reclaimed water,
Condition V.2 — Requirement inspection of high bulk water users,
Attachment: Approved Bulk Fill Reclaimed Water Uses - Established approved uses and
associated requirements for reclaimed water distributed through the bulk fill
operations.

per day. The Reclaimed wastewater system shall be designed and operated with no discharge of wastes to
the surface waters, pursuant to the application received March 3, 2008 and subsequent additional
information received by the Division, and in conformity with the project plan, specifications, and other
supporting data subsequently filed and approved by the Department of Environment and Natural
Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until February 28, 2013, and shall be subject
to the following specified conditions and limitations:
I. SCHEDULES [please review the entire permit for reporting, monitoring, and other on -going activities]
