4. Alternative Analysis Evaluation
a. Spray Irrigation: The applicant reviewed the Mecklenburg County soils survey for
the property. Based on the soils identified in the survey, the applicant estimates that
wastewater from only 300 homes could be treated using spray irrigation. The
applicant desires to construct 1,500 homes on the property; however, 1,500 homes
would result in 0.1 acre lots which may not be feasible (1500 home&1200 acres = —0. 1
acres per lot). Even if an on -site soil evaluation shows greater ground absorption
rates, it is highly unlikely that the lot yield will even come close to 1,500 homes.
Therefore, the applicant does not view spray irrigation as a viable alternative.
b. Subsur ,face: Refer to Spray Irrigation commentary above; however, lot yield is
anticipated to be only 150 lots.
c. Connect to regional sewer system: Municipal sewer is not immediately available to
the area at this time. A regional sewer interceptor is scheduled to be built along
Reedy Creek within the next 5 to 10 years (possibly 3 years). The regional sewer
d. Other disposal options: There are a few other wastewater treatment facilities in the
area (within 2 miles); however, the applicant has indicated that the permitted flows to
the facilities have already been allotted to other projects. In addition, it is unlikely
that any of the facilities could accept an additional 0.540 MGD. It is also unlikely
that the receiving stream could accept an additional 0.540 MGD without a significant
deterioration in water quality or alteration to the existing hydrology,
PART IV - EVALUATION AND RECOMMENDATIONS
The applicant desires to build a 1,500 home residential subdivision on the subject
property. The property is located in a rapidly expanding area of Mecklenburg County near the I-

h�Q Staff Rgport — LNPDES Permit NCO086771 AMlication) Pate 4 of 4
485 outerbelt which will soon encircle Charlotte. There are many other subdivisions and
commercial facilities under development in the area.
In order to accommodate the proposed 1,500 lots, the applicant must find away to treat
540,000 gpd of wastewater. A municipal sewer system is to be extended into the area within the
next 5- 10 years. At the time of municipal sewer availability, all of the existing wastewater
discharge facilities in the area will likely be requested by the division to connect to the regional
sewer system.
The proposed receiving stream is a small tributary to Reedy Creek (refer to the
description in Part 1, Item 10 above). The effect of a 0.540 MGD discharge to the stream would
appear to be significant. The wastewater flow should dominate base flow during drought and
even normal flow conditions. The base flow of the stream will also be diminished upon
construction of the subdivision as the increase in impervious surface area will increase storm
flow and reduce base flow in the channel. Because of these factors it appears that it would be
difficult for the stream to assimilate the proposed effluent. The stream's water quality would
likely mimic the effluent water quality.
If the treatment facility were approved, the hydrology within the channel would likely
fluctuate during the following 5 to 10 years. The flow and charmel characteristics as well as
aggradation and sedimentation rates would change with the addition of the discharge. It would
take a few years for the channel to reach a new equilibrium and aquatic organisms to adapt. It is
likely that the discharge would be removed around the time the channel reached a new
equilibrium (because of connection to regional sewer). Therefore, the channel would have to
adjust to the new hydrology and reach equilibrium again. The effects of the ongoing instability
on aquatic organisms and the overall health of the stream is difficult to predict.
Since a regional sewer system will be constructed in the area in the relativelynear future,
this Office does not recommend issuing the requested NPDES permit. According to the
application, spray irrigation appears to be a more viable interim alternative. The developer could
construct approximately 300 homes and use a spray irrigation system as an interim treatment
system. (actual soil analysis on the site and a non -discharge application would be necessary).

SECTION I
GENERAL
1.01 INTRODUCTION
Based upon the lack of availability of public sewer service, Carolina Water Service, Inc. of
NC is requesting an engineering evaluation di the provision of sewer service for the
development of a new single-family residential subdivision in eastern Mecklenburg County.
Carolina Water Service (CWS) has several water/sewer systems in operation in this area
generally referred to as the Cab Woods Service Area. The location of the proposed
development site off Harrisburg Road in Mecklenburg County is shown in Figure 1. The site
is situated outside the current boundary of the existing Cabarrus Woods Service Area. CWS
requested assistance from LandDesign Inc. in the conduct of the study to determine the most
feasible option for providing service to the site and to allow finther service to other land in
close proximity to this area.
1.02 SCOPE OF STUDY
The purpose of this study was to review potential alternatives for wastewater treatment and
disposal and to develop budget estimates for those alternatives deemed feasible, for service
specifically for the proposed site. The results of this study would also provide the basis for
service to other potential development in the area. Evaluation of potable water supply was
not a part of this study.

ALTERNATIVES FOR SERVICE
4.01 ON -SITE SETPIC/SPRAY IMGATION
A review of the existing soils on the site was conducted utilizing Mecklenburg County soils
survey and are predominately CeB2 and CeD2 soils. Based on this information and
topography and floodway evaluation, the estimated yield for the site utilizing SwuW
aSkq*#n isOMR040ts. Utilizing on -site septic does not appear to be an economically viable
alternative for the site since the
Evaluation of the site for possible spray irrigation indicates a potential yield ofJ804ftswbased
on setting aside approximately 48 acres in a dedicated disposal site. This does not allow for
area required for plant construction and wet w

4.04 CAROLINA WATER SERVICE (CWS)
Two alternatives appear possible for service by CWS: either construction of a new plant on
Reedy Creek Tributary No. 2, or conveyance of wastewater from the site to the Cab us
Woods Wastewater Treatment Plant.
The first alternative is shown as Figure 10 and depicts a new treatment plant to be located at
the extreme northwest comer of the site at the furthermost downstream point of the property
adjoining Reedy Creek Tributary No. 2. An effluent outtall approximately 1800 feet long
will be required to convey treated wastewater to the creek. All onsite wastewaters would be
collected and conveyed to the new plant site. The site would be situated to provide buffers
from adjacent property owners.
Under Alternative 2 - Option 1, wastewaters could be conveyed to the Cab Woods W`rP
via a new gravity trunk sewer down Reedy Creek Tributary No. 2 to Reedy Creek, then down
Reedy Creek to the Cambridge Pump Station. Expansion of the station and installation of a
new 12" force main to the plant would be required.
The other viable, more economically feasible option is the location of a new pump station on
the proposed development site along Reedy Creek Tributary No. 2, and installation of a force
main directly to the plant. These alternatives are depicted on Figure 11. Option I would be
prohibitively expensive due to the extensive length of trunk sewer and necessary rights of
way. Also, the Cambridge station would require a complete renovation and a new parallel
force main to the Cab us Woods Plant. Therefore, Option I has been eliminated as a
practical alternative.

EVALUATION OF ALTERNATIVES FOR SERVICE
5.01 BASIS FOR COMPARISON
After review of the various alternatives for serving the site, which would be capable of
allowing for the permitted development under the proposed zoning, three alternatives were
selected for economic comparison.
1. ` First, CScould provide sewer service by extension from the existing Cab .. as
"moods wastewater treatment plant. This option requires the construction of a 950
gpm high head pump station on site, approximately 25,500 L.F. of 12-' ch force main
d expansion of the plant.
. The second alternative would be to build plant on site with discharge
to Reedy Creek Tributary No. 2.
" The third alternative would be to extend' service to the CMUD system per their
requirements.
e alternatives were compared on the basis of capital costs, including non -construction
items such as engineering and opacity fees, and operation and maintenance costs annualized
over a 20-year design. life.
