PROJECT NO. 20.01107

' /
SECTION 1: DESIGN PARAMETERS
Per DWI guidance in response to the previously submitted ER/EID for the current project:
"Please note that the Division's flow analysis shows that the peaking factor for this facility
is approximately 3.0 whereas the proposed headworks is designed using 2.5 peaking
factor. Please adjust the peak hourly flow rate throughout the ER and design the proposed
headworks for peak hourly flow of 22.5 MGD."
Design Average Daily Flow (ADF) = 7.5 MGD
Design Peak Hourly Flow (PHF) = Peaking Factor (PF) x ADF
PF = 3.0
PHF = 3.0 x 7.5 MGD = 22.5 MGD (15,625 gpm)
SECTION 2: HYDRAULIC PROFILE
The hydraulic profile for the facility has been calculated from the existing influent manhole
upstream of the new replacement headworks through the existing influent pump station. Water
surface elevations have been determined for the following two (2) conditions:
1) NPDES permitted flow with all trains in service.
2) Peak Hourly Flow with one (1) train out of service and bypass channel (w/ manual bar
rack) in service
Hydraulic profile calculations primarily include a combination of friction losses in pipes (and open
channels), minor losses in fittings and valves, and head loss through treatment units. Note that
the hydraulic profile calculations have been performed in two (2) segments:
1) Open channel flow (Headworks structure)
2) Closed conduit flow (Headworks to Influent Pump Station)
Example calculations are provided below for reference.
Minor Head Loss Calculation in 30-inch Pipe (downstream of proposed Headworks):

Minor Head Loss (Hni) = k(2)

Example: Entrance Loss, 30-inch Pipe
v = 7.09 ft/sec
k = 0.5
g = 32.2 ft/secA2
7.z 2
(H.ni) = k(v ) = 0.5 (2 x032.2) = 0.39ft

Q 1.85
Frictional Head Loss (Hf) = 10.5L (�) D-4.87
Example: 150 LF of 30-inch Pipe
L = 150 ft
Q = 15,630 gpm
C = 110
D = 30 in
q,)1.8515,630 1.85(Hf) = 10.5L D-4.87 = 10.5(150 ft) ( 110 ) (30in)-4.87
Hf = 0.97 ft
Head Loss Calculation in 36-inch Open Channel:
Frictional Head Loss (Hf) = L (l49QAnR2/3)2
Example: 25 LF, 36-inch wide open channel
L = 25 ft
Q = 22.5 MGD = 34.8 cfs
n = 0.013, concrete channel
A = 7.7 ft2= 3 ft X 2.58 ft (flume depth)
R = 0.95ft = (7.7ft2/ (3ft + 2.58ft + 2.58ft)
Qn 2 34.8 cfs x 0.013 2
(Hf) = L (1.49 A R2/3) = 25 ft(1.49 (7.7 f t) (0.95 f t)2/3) = 0.04 ft
(Hf) = 0.04 ft
Comprehensive hydraulic profile calculations are appended at the end of this report.

SECTION 3: INFLUENT SEWERS
Wastewater currently enters the plant in an existing 30-inch diameter sewer which combines flow
from various outfall gravity mains and WWTP processes. The new headworks will receive flow
from a new 36-inch influent sewer. Existing sewers will be removed and replaced with new 36-
inch sewers to allow influent to flow by gravity into the new headworks. Proposed influent sewers
will be constructed at a minimum of 0.30% grade.
Critical Elevations:
Bottom of Screening Channel = 702.9'
36-inch Influent Pipe Invert = 702.9'
Upstream Connecting MH (Invert Out) = 703.18'
Full-Pipe Flow through 36-inch Gravity Sewer at 0.30% Grade = 23.6 MGD

I = x(R8) x S

Where: V = velocity in feet,second

D = 3 ft
r = 1.5 ft

A = 7.068583471
P = 9.424777961 ft
RH = 0.75 ft
% Full = 100.0%
V = 5.168250953 ft/s
Q = 36.53221326 ft3/s
23,609,747 gpd
As indicated above, the 36-inch gravity sewer will be able to handle the 22.5 MGD peak hourly
flow.

SECTION 4: PERFORATED PANEL SCREENS
The new screening facility will include two (2) mechanical influent screens, a common screenings
conveyor, and a common screenings washer/compactor. The perforated panel screens will be
installed upstream of the new vortex grit removal units, new 24-inch Parshall flume, and existing
influent pump station. The equipment will be exposed to the weather and will be fitted with heat
tracing and insulation to prevent freezing. Screenings will be discharged into a dumpster.
Design Parameters
• Type: Perforated panel screens
• Number: Two (2)
• Opening size: 6 mm (0.25 in)
• Peak flow capacity, each: 11.25 MGD
• Channel width: 4'-0"
• Screen depth, to discharge: 12' ±
• Downstream water level at PHF: 41.76 in
• Maximum head loss at PHF w/water level noted above: 6.00 in
Water levels are shown on the attached hydraulic profile. Screen head losses were taken from
design documents provided by screen manufacturer.

SECTION 5: VORTEX GRIT REMOVAL UNIT
Wastewater will flow from the screens to the grit removal system. Two (2) new grit removal units
will be provided with one (1) common grit classifier. Slide gates will split flow between the two (2)
grit removal channels.
The vortex-type grit removal units will have a capacity of 12 MGD each. The vortex unit requires
a motor-driven impeller, grit pump, washwater line, and other ancillary equipment. One (1) grit
classifier will be provided and sized to handle flow from the proposed grit unit and the future grit
unit with provisions to bypass partial flow during service interruption of one grit unit.
Design Parameters
• Type: 360° vortex units
• Number: Two (2)
• Peak flow capacity, each: 12 MGD
• Inside Diameter: 12'-0"
• Inlet Channel Width: 3'-0"
• Outlet Channel Width: 3'-0"
• Maximum Headloss: 0'-4" @ 22.5 MGD & downstream level of 3.13'
• Elevations:
o Top of wall for grit units: 710.65'
o Inlet Channel Floor: 702.9'
o Grit Chamber Inlet: 702.9
o Outlet Channel Floor: 702.9

SECTION 6: PARSHALL FLUME
An influent meter will be provided after grit removal. A 24-inch Parshall Flume will be used to
provide accurate measurements at low flows, and to minimize water levels at peak hourly flow.
Discharge equation: Q = 5.17 H 1'55 where Q = MGD and H = feet
Solving for head, H = (Q / 5.17) 0.645
Q, Flow H, Head
(MGD) (ft) (in)
2.72 (Current ADF) 0.66 7.9
7.5 (Permit Capacity) 1.27 15.3
22.5 (Design PHF) 2.58 31.0
"The ratio of downstream depth to the upstream depth, Hb/Ha, expressed as a percentage, is
referred to as the submergence ratio. Calibration tests show that the discharge of a Parshall flume
is not reduced (that is the flume is operating under free flow conditions) until the submergence
ratio exceeds the following values:
70 percent for flumes 1 to 8 feet"'
As indicated in the hydraulic profile and sheet C-202, there are no operating conditions that the
Parshall flume should become submerged; therefore, the discharge of the flume should never be
reduced.

A.(3.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 61%.
The permit holder shall perform at a minimum,quarterly monitoring using test procedures outlined in the
"North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998,or subsequent

permit limit,then multiple-concentration testing shall be performed at a minimum,in each of the two
following months as described in"North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised-February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest
concentration having no detectable impairment of reproduction or survival and the lowest concentration that
does have a detectable impairment of reproduction or survival. The definition of"detectable impairment,"
collection methods,exposure regimes,and further statistical methods are specified in the"North Carolina
Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge

October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period.The
Director may designate the most appropriate method(specific number and size of aliquots necessary,the time interval
between grab samples,etc.)on a case-by-case basis. Samples may be collected manually or automatically.Composite
samples may be obtained by the following methods:
(1) Continuous:a single,continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume:a series of grab samples collected at equal time intervals over a 24 hour period
of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection,or
(3) Variable time/constant volume:a series of grab samples of equal volume collected over a 24 hour period with
the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow
