RE: PCN Application for NW-33 and NW-39 Permits
401 Water Quality Certification
New Raw Water Intake on the Yadkin River in Davidson County, NC
Davidson Water, Inc. WTP
M&M Project No. 26023
To Whom It May Concern:
Davidson Water, Inc. (DWI) has requested Marziano &z McGougan, P.A. to design a
new raw water intake on the existing Water Treatment Plant (WTP) site to replace
three existing intakes as the primary means for raw water supply. The existing WTP and
intakes are located on the Yadkin River immediately south of US-64 on the Davidson-
Davie County line. DWI will maintain the three existing intakes in working order to
serve as a redundant backup system.
The existing DWI WTP has a total water treatment capacity of 20.0 mgd. Since its
original construction in 1969, it has been upgraded through several construction projects
that have increased the capacity to serve the increasing customer base and service area
expansions. DWI desires to construct the new intake with additional capacity to serve
the future upgrades to this facility and potentially a new water treatment facility.
On behalf of Davidson Water, Inc., please find enclosed seven (7) copies of the plans,
permit application, and dewatering plan narrative. An application fee of $475.00 is
included. We appreciate your review of the enclosed plans and look forward to working
with you on the project. Please contact me at this office if you have any questions or need
any additional information.
Sincerely,
Joseph W. McGougan, P.E.

9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: Property adjacent to the disturbed area is built upon by the
DWI water treatment facility and raw water reservoirs. These areas were cleared over several
phases since the WTP's initial construction in 1968. Adjoining land to the north and south
have land cover that can generally be described as wooded with intermittent farmland areas
that encroach upon the WTP site.
10. Describe the overall project in detail, including the type of equipment to be used:
DWI desires to construct a new raw water intake with additional capacity to serve the future
upgrades to the WTP facility and potentially a new water treatment facility. The river bottom
has been surveyed at the proposed intake location and this information is included in the
design plans included in this submittal. This information will be used to properly dewater the
site for construction of the headwall structure via port-a-dam and coffer dam. It is anticipated
that construction will proceed as follows:
1. Construct the caisson on the top of the river bank.
2. Dewater the Yadkin River and begin construction of the headwall structure.
3. Simultaneous with the headwall construction, directionally bore the raw water mains
from inside the caisson to penetrate the headwall located within the riverbed.
4. Construct the pump station on top of the caisson structure.
5. Complete forming of the headwall structure and install the screens.
6. After final inspection and acceptance of the underwater work, flood the dewatered
portions of the work area and remove the damming equipment.
It should be noted that DWI intends to maintain their three existing intakes in working order
to serve as a redundant backup system. The contractor will install the caisson with a portable
crane, deep-excavation trackhoe, and smaller supporting equipment. Rock
blasting/excavation is anticipated during construction of this project.
11. Explain the purpose of the proposed work:
Davidson Water, Inc. (DWP has begun the design and permitting process for a new raw
water intake on the existing WTP site to replace three existing intakes as the primary means
for raw water supply. The existing DWI WTP has a total water treatment capacity of 20.0
mgd. Since its original construction in 1968, it has been upgraded through several
construction projects that have increased the capacity to serve the increasing customer base
and service area expansions. Planning for an additional upgrade to 30.0 mgd is underway
and a new raw water intake will be necessary to supply this additional capacity and replace
the aging infrastructure.

VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: Proposed impacts consist of
temporary impacts associated with the dewatering of the Yadkin River, and permanent
impacts associated with the headwall and screen structures built in the riverbed. No wetlands
are located within proximity of the caisson or dewatered areas, with exception to the river.
2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,
separately list impacts due to both structure and flooding.

Size of watershed draining to pond:
livestock watering, irrigation, aesthetic, trout pond,
Expected pond surface area:
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
To construct a new intake with the desired capacity, temporary disturbance and permanent
structure within the Yadkin River is unavoidable. However, the dewatering_plan and proposed
construction methods will have a minimal disturbance width within the riverbed.
The river bottom has been surveyed at the proposed intake location to minimize the dewatering
area. Additionally, the raw water pump station will be mounted on top of the caisson, above the
100-year flood-plain and reducing the overall footprint of the structure on the top of the bank. As
stated in the construction methodology, simultaneous with the headwall construction, the raw
water mains will be directionally bored from inside the caisson to penetrate the headwall located
within the riverbed. This will eliminate heM disturbance of the river bank and allow the
headwall and pipeline to be constructed without excavation of the bank.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
Updated 11/1/2005

but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina (see DWQ website for most current
version.).
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions

the most recent North Carolina Division of Water Quality policy posted on our website at
http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description:
This raw water intake is designed as a superior alternative to the continued operation of the
existing intakes that supply the DWI WTP The cgpacity of the water plant to produce potable
water will not increase as a result of this project Therefore cumulative impacts cannot be
attributed to the construction of this intake. Subsequent upgrades to the WTP capacity will
require an Environmental Assessment and FONSI as acknowledged by DWI.

XV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
The sensitivity and importance of this project is paramount to the efficient operation of the
Davidson Water Inc. water treatment facility. This is the largest public utility in the U.S. with a
customer base of approximately 52,000 and a service population of 160,000 persons. The
condition of the three existing intakes should be noted as follows:
1. The pumps at each of these intakes are not capable of pumping from the river directly to
the water treatment facility headworks. Therefore, bypassing the existing raw water
reservoirs currently is not possible.
2. Flood events in the Yadkin River affect the operation of the DWI WTP. The middle and
downstream intake pump stations, as well as the, two lower reservoirs, are low enough to
be inundated during high flow events in the Yadkin River (less than the 100-year flood).
3. During the 2002 drought, extremely low water levels in the Yadkin River left two of the
three intakes with insufficient suction head. The pumps at the downstream intake
experienced an air lock and were rendered inoperable for several days. Also, the screw
pumps at the upstream intake were inoperable, leaving the middle intake as the sole
supply to the DWI water treatment facility.
The proposed raw water intake will alleviate these problems because it will be constructed at a
much lower elevation than the existing intake elevations, include a pump design that will be
capable of pumping directly to the water treatment facility, and have a capacity to serve the
future needs of the DWI service population.

Davidson Water, Inc. - Raw Water Intake Construction
Dewatering Plan June 2008
Dewatering Plan for the USACE NW-33 Permit
New Raw Water Intake Construction
Davidson Water, Inc.
Davidson County, North Carolina
Davidson Water, Inc. desires to construct a new raw water intake located on the eastern bank of the
Yadkin River, approximately 1,000 feet downstream of the US-64 bridge. The river bottom has
been surveyed at the proposed intake location and this information is included in the design plans as
part of this submittal. The survey and design plan has been submitted to a specialty contractor for
their review and comment.
According to the information provided by the specialty contractor, the port-a-dam barrier will be
installed as a three-sided barrier to retain the waters of the Yadkin River outside of the required
working area. Sandbags shall be placed along the sealing nylon apron along the length of the dam to
ensure adequate sealing of the port-a-dam to the river bottom and between the port-a-dam and the
riverbank.
It is anticipated that the dewatering of this section of the Yadkin River will encompass an area
approximately 200 feet in length with an average width of approximately 50 feet. The bottom
elevation of the port-a-dam will be approximately 632 feet-MSL, with a projected normal water
elevation of 639 feet-MSL. This allows for an approximate 3 feet of rise in the river before
overtopping could occur.
The length of time that the river will be dewatered is projected to be 45 days. This should allow
sufficient time to perform the following construction work in the riverbed:
1. Dewater the Yadkin River to expose the riverbed to the appropriate depth.
2. Excavate the riverbed to weathered bedrock, ensuring that the headwall footings will be
poured at an elevation of 627 feet-MSL.
3. Construct the headwall footings, anchored to the river bottom.
4. Poor the headwall and rough in piping.
5. Directionally bore the raw water intake pipeline through the headwall. All boring
equipment will be stationed inside the caisson installed on the riverbank.
6. Mount stainless steel intake screens to the footings and make all piping connections.
7. After final inspection and acceptance of the underwater work, flood the dewatered
portions of the work area and remove the damming equipment.
8. Length/height of the northernmost wing wall section and final riverbed profile will be
dependent upon the depth of sediment in this area. The wall can be cast in place
underwater and anchored to'the river bottom without additional dewatering.
