Aqua North Carolina, Inc. (Aqua) offers the following response to the above -referenced Compliance
Evaluation Inspection performed on September 18, 2012.
"It is-recommended_that. Aqua: consider. the installation=of a grit removal' unit as: soon as possible"
Response:
In 2013,-Aqua plans to rework the splitter box and install a new bar screen. We believe
this will increase the removal of smaller material that may be currently passing through
and also improve the overall treatment processes in the WWTP.
• "It is recommended that Aqua, if not already doing so, investigate sources of I/I."
Response:
Aqua has performed previous investigations and has performed work over the years to
prevent I/I. This work has included improvements made at Lift Station #2 and #3. In
2013, Aqua will continue to investigate potential sources of I/I which will include broken
service laterals, unprotected manholes, and other potential sources.
• "It is strongly recommended that the smaller side of the facility be cleaned and rehabilitated to
offer operational flexibility."
Response:
Aqua will clean and rehabilitate the smaller side of the WWTP beginning in early 2013.

Aqua is uncertain of the reason for the "unusual rust color." However, if we can make
this determination, we will advise you.

Aqua is in the process of developing a written standard operating procedure (SOP)
specific to process control sampling at Woodlake, which should be fully implemented by
the end of 2012.
