Hey there,
Just to let you both know that we issued the NWP 12 for this project (which matches the GC you all issued)
and we also issued a NWP 33 for the cofferdam.... not sure how that affects DWQ, if at all.
Hope you are doing well.

draw-down valve or spillway, etc.):
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.):
Size of watershed draining to 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.
Coffer dam (Port-a-Dam) shall be installed during a low flow or normal flow of the river and
then the retained water will be pumped out. Structure impacts are minimized due to the coffer
Page 7 of 12
dam. The structure is adjacent to the structure to be replaced and would therefore create the least
disturbance to the river.
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 March 9, 2000, 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,
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 NCWRP 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, available at
hllp://h2o.enr.state.nc.us/ncwetlands/stnngide.html.
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
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
Page 8 of 12
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at hqp://h2o.enr.state.nc.us/wrp/index.htm. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide
the following information:

1. DESCRIPTION OF EXISTING WATER SYSTEM
The Harnett County Department of Public Utilities (HCDPU) owns and operates, a water treat>nt plk.t
that can provide up to 12.0 million gallons per day of treated water to its customers that reside within its
district boundaries and, in some cases, contiguous to its boundary. This particular project will require the
construction of new, more efficient and modern raw water intake structure to replace the existing intake
structure.
2. AREA SERVED BY THE PROPOSED DISTRIBUTION SYSTEM IMPROVEMENTS
The County DPU provides water service through seven (7) water & sewer districts that encompass the
entire County boundaries. Additionally, water service is provided to Fuquay-Varina, Johnston County,

The area to be served by the proposed project remains unchanged since this project involves work at the
existing water treatment plant. The County's existing water distribution system, pumping and storage
facilities have adequate capacity to meet the needs of their existing service area to include foreseeable
growth. This project will not change operating capacities at the water treatment plant. Additionally, the
proposed raw water intake will have essentially the same hydraulic capacity as the existing raw water
intake that is to be abandoned. This is particularly true since the proposed intake will tie into the existing
raw water inlet flume to the raw water pumping station.

5. DESCRIPTION OF THE FUTURE SERVICE AREA OF THE PUBLIC WATER SYSTEM FOR 20
YEARS
Future service area includes undeveloped areas within Harnett County and areas surrounding Harnett
County. Harnett County currently serves a very large area within the State relative to water distribution.
The utility system continues to provide expansion and construction to serve customers that grow within its
service boundaries. The existing water treatment plant currently has adequate capacity to serve all of its
customers and this raw water intake replacement project will correct an operation and maintenance problem
with the river withdrawal system that has been creating efficiency problems with the raw water facilities.
6. ALTERNATIVE PLANS FOR MEETING THE WATER SUPPLY REQUIREMENTS
Harnett County obtains its raw water supply from the Cape Fear River. The Cape Fear River has provided
the raw water supply to the water treatment facility located in the Town of Lillington since the 1940's.
Groundwater is not sufficient to provide the 12 million gallons per day capacity that is required at this
facility. There are no other major tributaries with sufficient quantity or quality to provide the supply.
Harnett County is studying future plans to withdraw water from inland reservoirs that have been created by
to the extensive mining operations along the Cape Fear River. To a lesser extent County personnel are
researching the upper Little River as a supplemental raw water supply. However, for the purpose of this
project an alternative water supply is not necessary.
7. FINANCIAL CONSIDERATIONS FOR STATE LOAN AND GRANT SUPPORT
This project will be funded from local, budgeted funds of the water utility. No State loan or grant support
is required.
7A POPULATION RECORDS AND TRENDS
The year 2000 estimate of the population served by HCDPU is about 88,000. The year 2020 estimate is
about 137,000. This project will provide a new raw water intake structure to replace the existing raw water
intake structure with a new, more modern and efficient structure having the same hydraulic capacity. No
new customers will be created as a result of this project.
7B PRESENT AND ANTICIPATED FUTURE WATER DEMANDS
The year 2000 estimate of the average daily service area demand is 6.4 mgd with a peak of 9.6 mgd. The
year 2020 estimate of the average daily service area demand is 14.0 mgd. The numbers are based upon
DPU projections of water use.
7C. PRESENT AND FUTURE YIELDS OF SOURCES OF SUPPLY
The present yield of Harnett County sources of water supply is currently approved as 12.0 mgd. Harnett
County has been granted approval from the State of North Carolina to withdraw up to about 24 mgd from
the Cape Fear River. The water treatment plant can operate on a periodic basis of up to about 16.0 mgd.
Harnett County will be seeking additional approval for withdrawals in excess of 40 million gallons per day
from the Cape Fear River in the foreseeable future. The Cape Fear River average daily flow at the point of
the existing raw water intake is probably in excess of 300 million gallons per day.
8 CHARACTER OF SOURCES OF WATER SUPPLY
The Cape Fear River as previously stated, provides all of the raw water supply to the water plant. The
plant is designed and approved to use the water from the Cape Fear River. Records of the water quality are
at the water plant and at NC DENR in Raleigh, NC.

This project's purpose is to correct the problem of pumping silt contained in the raw water to the holding
reservoir.
9. PROPOSED WATER TREATMENT PROCESSES
Not applicable for this report.
10. PURCHASED WATER
HCDPU water system has reciprocal agreements for the purchase of water from the City of Dunn and
Johnston County. The Dunn agreement is for a pass-thru in their service area. The Johnston County
agreement is for emergency use for the East Central Water & Sewer District only.
12. DESIGN BASIS FOR INTAKE SYSTEM
Design calculations relative to hydraulic capacities of the new intake structure are attached to this
preliminary engineering report. The new intake structure when completed will have approximately the
same hydraulic capacity of the existing intake structure that will be abandoned. This is particularly true
since the new intake structure will tie into the existing pump station raw water inlet flume via a 60-inch
diameter pipe. The existing raw water intake can provide almost 50 million gallons per day of raw water
supply to the raw water pumping station depending upon the water level in the Cape Fear River. The raw
water is collected at the raw water pumping station and pumped to a raw water holding reservoir that has a
capacity of about 60 million gallons. The raw water reservoir was constructed and placed into operation
around 1994. Since that time, the reservoirs' capacity has been reduced in excess of 50% due to sediment
being pumped from the Cape Fear River along with the raw water. The existing intake structure accesses
the Cape Fear River through an open channel flume and has bar screens and a traveling screen that provides
catchment of large debris before entering the raw water pumping station. However, these screens do not
provide catchment of the fine silts that are carried in suspension in the Cape Fear River waters.
Additionally, fish can pass through the openings in the screens and are subject to being pumped into the
raw water reservoir. This situation has been observed and continues today.
The new raw water screen will be of a more modern and maintainable design. It will utilize a coarse screen
for initial intake of raw water from the Cape Fear River. These intakes screens will be placed at essentially
the same elevation as the existing intake flume. Once passing these screens, the raw water will enter a
concrete chamber that will contain three (3) stainless steel, fine mesh screens that are designed to filter the
fine sediments that are currently being deposited in the existing raw water reservoir. Additionally, any fish
that enter through the core screens can not be transferred into the existing raw water reservoir through the
fine screens. The fine screens will be maintained by back surging air under pressure through each screen
which will have the affect of shaking lose the sediment that has collected. The sediment will then settle to
the floor of the concrete chamber where a mechanical scrapper will move the solids into a sump. From the
sump, the solids and any small fish will be transported through an open piped air lift system back to the
Cape Fear River and just downstream of the intake. Large fish will have the option of accessing the main
channel back through the coarse screens. Velocities through the screens will be designed at less than 1.0
fps.
The construction of this project will require a coffer dam to be constructed in a small area of the Cape Fear
River. A "port-a-dam" type of dewatering system will be used to create the coffer dam. A port-a-dam was
recently used in the same area to provide a 36-inch water line crossing from the water treatment plant on
the south side of the Cape Fear River to Fuquay-Varina on the north side of the Cape Fear River. The port-
a-dam type of dewatering system has been shown to be an environmentally sound and safe method of
creating a coffer dam that will eliminate the discharge of construction silt or foreign agencies into the
water. This system has also been used to cross the Neuse River near Raleigh with great success.
After dewatering of the area enclosed by the coffer dam, the construction of the concrete intake will require
removal of existing rip rap. This rip rap was placed in the early 1990's when the original raw water intake
and pumping station were constructed. The rip rap purpose was to provide a diversion for silt coming
County of Harnett 3of 4 Marziano & Minier, PA
Raw Water Intake Structure Consulting Engineers
down the river from the intake structure. This rip rap has not worked satisfactorily as previously discussed.
In addition to removal of the rip rap it will be necessary to excavate about 6 to 7 feet into the existing river
bottom.
The structure will be formed utilizing conventional, prefabricated concrete forms for placing reinforced
concrete. All of the internal screens and piping to be placed in the concrete structure will then be installed
and a removable, reinforced aluminum top will be sealed over the screens. The removal top is necessary to
provide future access to the screens if necessary and also expedite the construction process by not requiring
forming of elevated concrete surfaces. The excavated materials and rip rap will be hauled away from the
site and legally disposed of. After the installation of the concrete structure, the water will be allowed to
return to the coffer area and the port-a-dam will be removed.
All other work associated with the intake structure will be performed outside of the stream flow of the Cape
Fear River. The construction period is expected to be of fairly short duration. It is expected that about 90
days will be required for construction within the limits of the port-a-dam area. The port-a-dam area is
shown on the design plans as approximately 0.066 acres. The footprint of the proposed intake structure that
lies within the normal water level limits of the Cape Fear River is approximately 941 square feet (0.0216
ac).
All of the construction will be supervised by Harnett County construction observation personnel and by
staff of the design engineer. All work will be in conformance with NC Department of Environment and
Natural Resources requirements applicable building codes and construction material standard
specifications.
13. MAXIMUM DAILY TREATED WATER SUPPLY AND MAXIMUM DAILY DEMAND
The year 2010 maximum daily water demand is projected at 14.3 mgd.
Basis: 9.6 mgd maximum da(20001 x 9.5 mgd projected average day
6.4 mgd average day
The existing HCDPU water plant located in Lillington, NC can currently supply up to 12.0 mgd of treated
water. Preliminary plans to expand the plant to 24 mgd are underway.
14. PRIORITIZED LIST OF INFRASTRUCTURE IMPROVEMENTS
Infrastructure improvements that are currently needed and proposed for HCDPU water distribution system
involve replacement of deteriorating DI Pipe and/or undersized PVC or ductile iron water lines. These
improvements are prioritized annually based on the amount of deterioration and the need to upgrade the
size of the existing lines for proposed extensions.
Also a comprehensive hydraulic study began in the Fall of 2003 to identify needed distribution system
improvements. These improvements will be recommended to provide necessary hydraulic capacity in the
distribution system to transport the projected water demands in the service area. These improvements will
also be prioritized annually. Harnett County is currently working on water plant pilot studies that will be
utilized to develop plans and specifications to increase the water plant capacity to 24.0 million gallons per
day and beyond.
This preliminary engineer's report submitted this 27th day of November, 2003.
