Re: Recommendation to Remove the Wylie WVVTP from Service
Dear Ms. Manson:
The purpose of this letter is to recommend taking the Wylie Wastewater Treatment Plant ("WWTP")
out of service in the near future. On April 29, 2009, Joe Stankiewicz, Bnb Reeves, and Ken
Wesson from NTMWD met with Chris Holsted and Michael Sferra to discuss this step as ar? interim
measure to provide a more cost-effective approach for treatment services.
NTMWD has evaluated total flow from the cities of Wylie and Murphy and determined the Mudcly
Creek WWTP has sufficient rated capacity at 10 MGD to treat all flow from both cities. The current
average daily flow for both cities is approximately 6 MGD. At this time, approximately 5 MGD is
being treated at the Muddy Creek WWTP and 1 MGD is being treated at the Wylie WWTP. The
Texas Commission on Environmental Quality (TCEQ) discharge permit for the Muddy Creek
WWTP requires NTMWD to commence with planning for additional capacity for the cities when flow
reaches 75% of the rated plant capacity (i.e., 7.5 MGD), and to be under construction when the
plant flow reaches 90% of the rated capacity (i.e., 9.0 MGD). Based on current flow, the cities of
Wylie and Murphy would have to experience population growth of approximately 20-25% before a
ne?~ te commenc~ plan^;^g fcr ud~„i~ral c«Facity. Thc c~uas wouid 'riave to grow ~y
approximately 40-45% before construction would be required to commence for additional capacity.
Based on the current capacity of the Muddy Creek 1NWTP and thF current flows, it is the opinion of
the NTMWD staff that the Wylie WWTP can be taken out of service at this time and all flow
transferred to the Muddy Creek WWTP for treatment.
During the meeting with Mr. Holsted and Mr. Sferra, the potential value of the Wylie WWTP ana
future use as an asset was discussed. NTMWD feels that the Wylie WWTP provides continuing
value even if it is taken out of service as an interim strategic move. At some point in the future, it
may make economic sense to place the plant back in service so that the next phased expansion of
Muddy Creek WWTP can potentially be delayed. Depending on economic conditions and the
actual future growth rates of Wylie and Murphy, the 2 MGD capacity of the Wylie W~YTP could
~ delay construction of the expansion for some time period. If this strategy is adopted, the plant
equipment would still receive basic preventive maintenance tasks performed on a monthly basis so
that facilities are preserved and kept in good operating condition. With this approach, maintenance
costs associated with the plant would be minimal while still allowing the plant to resume service at
ihe appropriate future time.

By taking the Wylie plant out of service and taking into account the additional cost of treatment at
the Muddy Creek WWTP, NTMWD believes that the City of Wylie may potentially realize an overall
savings for wastewater treatment in the range of $100,000 to $200,000 annually. This action would
require that the containment basins and facilities be cleaned and debris removed.
NTMWD currently projects that sufficient budgeted funds exist in the FY 2008-09 operating budget
to cover the cost of the cleaning operation required for plant shutdown. NTMWD is currently
preparing the FY 2009 - 10 operating budget for the Wastewater System. Based on the outcome
of the April 29, 2009, discussion with Mr. Holsted and Mr. Sferra, NTMWD is planning for the Wylie
WWTP to be taken out of service in the near future and is adopting the budget measures
associated with this action. An Operating Budget for the Wylie WWTP will continue to exist that will
include costs associated with the maintenance efforts described above, as well as for the cost of
the discharge permit which will remain in place. Should the decision be made to take the plant out
of service, some off-site odors may result during the cleaning process. It is recommended that
information be disseminated to area residents, which would explain the near term and long-term
plans for the plant and the possibiliry of fugitive odors during the short time that would be required
to clean the plant. NTMWD will be willing to assist the City in developing this information.
NTMWD would appreciate written concurrence from the City of Wylie regarding the disposition of
the Wylie WWTP. Assuming that the City of Wylie agrees with the decision to remove the Wylie
~ WWTP from service as reviewed in this letter, we respectfully request your acknowledgement by
signing in the space provided below and returning a copy for our files. If you have any questions,
please contact Mr. Ken Wesson, Wastewater Systems Manager, or this office directly.
Sincerely,
