2041 US Hwy 70 East Apartment Complex
McDowell County
BEA Project No. 515720
Dear Mr. Weaver:
On behalf of Ms. Beverly Lail, Brooks Engineering Associates (BEA) is submitting the enclosed
ATC application for Larry Miller associated with NPDES Permit NC0088901. This Cover
Letter is intended to provide a narrative description of the project and serve as the request for the
Authorization to Construct.
Project Description
This submittal is for a wastewater treatment system to serve an existing multi-family apartment
building located at 2041 HWY 70, Marion,NC (McDowell County PIN 1712-52-6802). The
apartment building contains eight units with two bedrooms each. The apartments have been
operating with a slowly failing septic system. The proposed system is designed for a daily
design flow of 1920 gpd domestic strength raw wastewater from the apartment building. The
design flow is based upon 120 gpd per room in accordance with 15A NCAC 02T .0114
wastewater design flow rates.
In 2008, DWQ notified the property owner that the existing septic system was failing. In 2009,
NDPES permit NC0088901 was issued for a new system that authorized a 0.002 MGD design
flow with discharge to Forsyth Creek(Stream Index 11-25, Class C, Catawba River Basin).
The following are proposed by the enclosed plans and specifications:
• A 3,000-gallon Shoaf(STB-186)precast concrete septic tank to serve as a combination
septic and EQ tank with a Zoeller duplex pump system.
• A Southern Concrete and Materials 75-gallon precast distribution box with auto-levelers
to distribute equal flow to two 1000 GPD AquaSafe Aerobic Treatment Units.
• The proposed AquaSafe units (Model AS 1000CU) are comprised of an aeration mixing
compartment, center clarifier compartment, and an attached 68-gallon UV disinfection
tank.
• Effluent from the AquaSafe units will be piped to flow meter vault for continuous
discharge measurements prior to discharging to a post-aeration cascade apparatus.
Enclosed with this Cover Letter and request for the Authorization to Construct are one set of
sealed plans, specifications, calculations, ATC application and a CD with the same documents.

1.0 SYSTEM SUMMARY& PROJECT INFORMATION
1.1 Project Summary
These specifications and accompanying engineering plans are for a wastewater treatment
system to serve an existing multi-family apartment building located at 2041 HWY 70, Marion,
NC (McDowell County PIN 1712-52-6802). The apartment building contains eight units with two
bedrooms each. The proposed system is designed for a daily design flow of 1920 gpd domestic
strength raw wastewater from the apartment building. The design flow is based upon 120 gpd
per room in accordance with 15A NCAC 02T .0114 wastewater design flow rates.
Existing Conditions
In 2008, DWQ notified the property owner that the existing septic system was failing. In 2009,
NDPES permit#NC0088901 was issued for a new system that authorized a 0.002 MGD design
flow with discharge to Forsyth Creek (Stream Index 11-25, Class C, Catawba River Basin).
Proposed Treatment System
The following are proposed by the enclosed plans and specifications:
• A 3,000-gallon Shoaf(STB-186) precast concrete septic tank to serve as a combination
septic and EQ tank with a Zoeller duplex pump system.
• A Southern Concrete and Materials 75-gallon precast distribution box with auto-levelers
to distribute equal flow to two 1000 GPD AquaSafe Aerobic Treatment Units.
• The proposed AquaSafe units (Model AS1000CU) are comprised of an aeration mixing
compartment, center clarifier compartment, and an attached 68-gallon UV disinfection
tank.
• Effluent from the AquaSafe units will be piped to flow meter vault for continuous
discharge measurements prior to discharging to a post-aeration cascade apparatus.
This wastewater treatment system is designed in accordance with current effluent limits in
NPDES Permit#NC0088901.

2.0 PIPING & COLLECTION
2.1 Location of Collection System
There is no collection system, only an existing 4" gravity service line from the apartment building
that will be rerouted to the new septic tank once the proposed system is ready for operation.
2.2 Sizing & Material
The service line shall be constructed of non-pressure pipe and fittings which shall be Schedule
40 PVC meeting ASTM D-3034. All non-pressurized piping shall maintain a minimum slope of
1/8-inch fall per lineal foot. Bedding and compaction shall be to a 95% Standard Proctor Test
(ASTM Standard D 698) and trenching and installation shall be consistent with ASTM D2321.
These specifications do not cover interior or initial building connections.
All pressurized lines shall be constructed of Schedule 40 PVC SDR 21 meeting ASTM D-2241
of a size as noted on the engineering plans.
2.3 Burial
Bedding and installation shall be consistent with ASTM Standard F 667. These specifications do
not cover interior or initial building connections. The following are general location and
separation guidelines:
• Typically, a 3-foot minimum cover shall be maintained on all sewer lines.
• Sewer lines may cross a water line if 18 inches clear separation is maintained,
with the sewer line passing under the water line. The sewer line shall be
constructed of ductile iron pipe and the water line shall be constructed of ferrous
material equivalent to water main standards for at least 10 feet on either side of
each crossing.
• Sewer lines may cross a storm drain if at least 12 inches of clear separation is
maintained or the sewer pipe is of ductile iron or encased in ductile iron pipe for
at least 5 feet on either side of the crossing.
• Sewer lines may cross a stream if at least three feet of stable cover can be
maintained with a horizontal boring or the sewer line is of ductile iron pipe or
encased in ductile iron pipe for at least 10 feet on either side of the crossing and
protect against the normal range of high and low water.
4

• A minimum separation of 100 ft from any well is required unless the sewer line is
constructed of pipe materials meeting water main standards. The minimum
separation shall not be less than 25 ft from a private well or 50 ft from a public
well.
Three feet minimum and ten feet maximum cover shall be provided for all sewers unless ferrous
material pipe is specified. Ferrous material pipe, or other pipe with proper bedding to develop
design supporting strength, shall be provided where sewers are subject to traffic bearing loads.
Additional protection shall be provided for sewers that cannot be placed at a depth sufficient to
prevent damage.
2.4 Steep Slope Installation
Sewers on 20 percent slopes or greater shall be anchored securely with concrete, or equal, with
the anchors spaced as follows:
a. Not greater than 36 feet center to center on grades 21% to 35%;
b. Not greater than 24 feet center to center on grades 35% to 50 %; and
c. Not greater than 16 feet center to center on grades 50% and over.
There are no steep slopes on this project.
2.5 Trenching
Trench excavation shall conform to the line, depth and dimensions shown on the plans or as
directed by the Designer. The trench shall be properly braced and shored so that workmen may
work safely and efficiently. If unstable conditions are encountered, the Designer shall be
notified in order that proper bedding materials may be selected. Trench excavation or
excavation for pipelines shall consist of excavation necessary for the construction of sewers,
conduits and other pipelines and all appurtenant facilities thereof, pipe embedment materials,
and pipe protection, insulating and sleeving in ductile iron pipe, as called for on the plans. It
shall include site preparation, backfilling and tamping of pipe trenches and around tanks and the
disposal of waste materials, all of which shall conform to the applicable provisions of these
specifications. When muck, quicksand, soft clay, swampy or other material unsuitable for
foundations or subgrade are encountered which extend beyond the limits of the excavation,
such material shall be removed and replaced with pipe foundation material as specified in the
engineering drawings. Surface drainage shall not be allowed to enter excavated areas.
5

Rock encountered in trench excavation shall be removed for the overall width of trench which
shall be as shown on the plans. It shall be removed to a minimum depth of three (3) inches
below the bottom of the pipe. Clean compacted backfill shall replace the excavated rock.
The pipe material listed above shall be installed in accordance with the manufacturer's
recommendations and the requirements of these specifications. All sewer lines shall be laid to
the line and grade shown on the plans. No deviations from line and grade shall be made, unless
they have been approved by the Designer. The pipe interior shall be kept clean before and after
laying by means approved by the Engineer. Pipe ends shall be plugged at the end of each work
day or when work is temporarily stopped. The plugs shall be watertight so that water and debris
will not enter the pipe.
All backfilling shall be done in such manner as will not disturb or injure the pipe or structure over
or against which it is being placed. Any pipe or structure injured, damaged or moved from its
proper line or grade during backfilling operations shall be opened up and repaired and then re-
backfilled as herein specified.
The Contractor shall replace all surface materials and shall restore paving, curbing, sidewalks,
gutters, shrubbery, fences, sod, and other surfaces disturbed, to a condition equal to that before
the work began, furnishing all labor and materials incidental thereto as provided elsewhere in
these specifications. The backfilling of the trench after the pipe installation and testing shall be
in accordance with the standard detail.
2.6 Testing
All gravity sewer lines shall be tested by Low Pressure Air Exfiltration Testing with the following
steps.
1. All branch fittings and ends of lateral stubs shall be securely plugged at each manhole.
All stoppers shall be adequately braced when required.
2. Air shall be slowly supplied into the plugged pipe line until the internal air pressure
reaches 4.0 pounds per square inch or 4.0 pounds per square inch greater than the
6

average back pressure of any ground water that may submerge the pipe. At least two
minutes shall be allowed for temperature stabilization before proceeding further.
3. Calculate the pressure drop as the number of minutes for the air pressure within the
pipeline to drop from a stabilized pressure of 3.5 to 2.5 psig.
4. The time allowed for mixed pipe sizes of varying lengths should be calculated as
described in ASTM C828-76T.
5. The following times are for one pipe size only:
Pipe Size (inches) Time, T Allowable Air Loss, Q
(sec/100 ft) (ft3/min)
4 36 2.0
6 42 2.0
8 72 2.0
10 90 2.5
12 108 3.0
15 126 4.0
18 144 5.0
21 180 5.5
24 216 6.0
27 252 6.5
6. The pipe line shall be considered acceptable if the time interval for the 1.0 psi pressure
drop is not less than the holding time listed in the above table.
7. If the test fails, the Contractor will be required to locate the cause of the failure, make
necessary repairs, and repeat all testing of the line until the test is passed.
For pressure sewer lines the following Hydrostatic Testing Procedure shall be utilized.
1. As a minimum, all sewer force mains shall be tested in accordance with the Hydrostatic
Testing Requirements of AWWA C600.
7

2. After pipe has been laid and backfilled, all newly laid pipe or any valve section thereof
shall be subject to a hydrostatic pressure of not less than 150 psi or 1-1/2 times the
working pressure, whichever is greater. The duration of the pressure test shall be two
hours. Each valve section of the pipe shall be slowly filled with water. All air shall be
expelled from the pipe while the pipe is being filled and before the application of the
specified test pressure. Taps may be required at points of highest elevation. These
taps are to be tightly plugged after completion of the test.
3. The test pressure shall be applied by means of a pump connected to the pipe in a
manner satisfactory to the Project Engineer. The pump, pump connections, gauges,
and all necessary apparatus and labor shall be furnished by the Contractor. The
Contractor shall calibrate the gauges in the presence of the Design Engineer.
4. A test shall be made only after a part or all of the backfilling has been completed and
at least 36 hours after the last concrete thrust block has been cast with high-early
strength cement or at least seven (7) days after the last thrust block has been cast
using standard cement.
5. Any cracked or defective pipes, fittings, or valves discovered during hydrostatic
pressure tests shall be removed and replaced with sound material and the test
repeated until satisfactory to the Design Engineer. No payment shall be made for the
removal and replacement of defective pipes and appurtenances.
6. Leakage shall be defined as the quantity of water that must be supplied into the newly
laid pipe, or any valved section thereof, to maintain pressure within 5 psi of the
specified test pressure. Leakage shall not be measured by a drop in pressure in a test
section over a period of time.
7. Allowable leakage shall not exceed the following U.S. gallons per hour reported in
Table 1:

If the pipeline under test contains sections of various diameters, the allowable leakage will
be the sum of the computed leakage for each size.
Alternatively, no pipe installation will be accepted if the leakage is greater than that
determined by the following formula:
In inch-pound units,
L = SD,F
133,200
Where:
L = allowable leakage, in gallons per hour
S = length of pipe tested, in feet
D = nominal diameter of the pipe, in inches
P = average test pressure during the leakage test, in pounds per square inch
(gauge)
The Contractor shall notify the Project Engineer when the work is ready for testing, and all testing
shall be done in the presence of a representative of Brooks Engineering. All labor, equipment,
water, and materials, including meters and gauges, shall be furnished by the Contractor at his
own expense.

2.7 Valving
Valving shall be consistent with material types and sizes of piping as shown on the Engineering
Plans. All high points in pressure distribution lines should have air release valves and low
points ("bellies") should have pressure cleanouts. Sufficient isolation should be incorporated to
allow for line maintenance without having to shut down the entire distribution system.
