Capital Improvements Plan

1. GOAL STATEMENT
This Capital Improvements Plan is a planning tool for the Town of Benson to use for future wastewater
collection systems improvements. It serves to identify collection system improvement projects which,
upon completion, can be expected to reduce the quantity of unmetered wastewater treated at the Town's
wastewater treatment plant (WWTP) and can potentially lower the billing rates charged to the wastewater
customers in the Town. In addition, the information provided should be a benchmark reference document
by which the Town can measure progress. It will be used to help support future grant and loan
applications as the Town begins to implement the individual projects described herein. Finally, the
Capital Improvements Plan represents a vision of the Town's future and will guide local leaders and
volunteers in appropriate, planned growth to better serve the needs of its citizens. It should be noted that
this document is for the Town's wastewater collection system only. There are no projects related to the
Town's WWTP in this CIP. The Town is advised to consider completing similar documents to those
submitted herein for the WWTP, as the capacity of the plant should be expanded and as the infrastructure
at the WWTP continues to age, malfunction, and need to be replaced.

2. DESCRIPTION OF PROJECT AREA
2.1 DEMOGRAPHICS
Population data for Benson and Johnston County are tabulated below. Historical census data from 1910
to 2010 for Johnston County and the Town of Benson were obtained from the N.C. Office of State Budget
and Management and the U.S. Census Bureau. The Office of State Budget and Management makes
projections for future county population growth using U.S. Census Bureau data. The Town of Benson has
experienced a steady population increase in the last 40 years, accompanying the growth shown by
Johnston County (due to its proximity to the Raleigh -Durham area). In fact, the Town's population shows
an increase of over 15% from 2000 to 2014, mirroring (but not matching) the county's growth of over
46%. As shown, Benson has grown at an average rate of about 39 people per year over the decade ending
in 2010. The average rates of growth are projected to be 88 people per year during the decade ending in
2020. Rates are projected to increase even more in the 2020's to around 110 per year. These projections
are by NC Demographer which projects increased growth for Johnson County. The table below projects
Benson remaining the same percentage of that county.

2.2 LAND AREA CONFIGURATIONS
2.2.1 TOPOGRAPHY AND HYDROGRAPHY
The topography of the project area is generally flat to gently rolling with elevations ranging from around
200 to 300 feet above sea level. The USGS Quad maps show the blue line streams that exist within the
Town. The Town is located just north of the drainage divide between the Cape Fear river basin and the
Neuse river basin. Streams and creeks drain in the Town drain generally to the east and north into
Hannah Creek then into the Neuse River. The USGS Topographical map can be found in Appendix A of

2.2.2 SOILS
The soils that exist within the Town include Bibb sandy loam (Bb), Blanton sand (BnA), Cowarts loamy
sand (CoB & CoC), Faceville loamy sand (FaA & FaB), Fuquay San (FuA), Gilead sandy loam (GeB &
Gel)), Goldsboro sandy loam (GoA), Lynchburg sandy loam (Ly), Malboro sandy loam (MaA & MaB),
Norfolk loamy sand (NoA & NoB), Norfolk Urban land complex (NuA), Rains sandy loam (Ra), Rains
Urban land complex (RbA), Uchee loamy coarse sand (UcC), Udorthents (Ud), Varina loamy sand (VrA
& VrB), and Wagram loamy sand (WaB). The two most predominant soils are the Norfolk Urban land
complex (NuA) and the Rains Urban land complex (RbA). The description of these soils is as follows:
-Norfolk Urban land complex (NuA) is a very deep and well -drained soil. The soil is well suited to
parks, open spaces, building sites, lawns and gardens. If the soil is not protected, erosion is a
moderate hazard. These soils generally have high water tables of 4 to 6 feet that occurs in January
and February.
-Rains Urban land complex (RbA) is a poorly drained soil. The soil is suited for shopping centers,
houses, municipal buildings, parking lots, roads, and other impervious surfaces. These soils are
noted for their wetness and have water tables 0-1 foot in depth occurring in November through
April.
The wetness and high water tables contribute to the I&I that are present in the Wastewater Collection
system.
The NRCS Soils map can be found in Appendix A of the AMP.

3. DESCRIPTION OF EXISTING WASTEWATER COLLECTION
SYSTEM
3.1 GENERAL STATUS
The Town of Benson owns and operates its wastewater collection system, receiving wastewater from
approximately 1,506 in -town sewer customers and 37 out-of-town customers. The customer breakdown is
as follows: approximately 1,296 residential customers, 242 commercial customers, 7 industrial customers,
and 12 institutional customers. The gravity sewer piping consists of 6 inch through 24 inch diameter pipe
totaling 34.97 miles in length. The sewer pipe is laid at a downward grade to allow for flow of sewage.
When piping gets uneconomically deep or cannot serve an area due to natural topography, a sewage pump
station is installed to pump the sewer to a higher elevation to be served by the gravity sewer. The
collection system currently contains 11 wastewater pumping stations.
Both the Gravity Collection sewer system and Wastewater Pumping stations are permitted as the
wastewater collection system by the NC Department of Environmental Quality. The permit number is
WQS00109 and is effective until June 30, 2023.
The Town has pursued rehabilitation of a portion of its existing sewer system to remedy its sewer
infiltration and inflow (I&1) problems. This rehabilitation occurred primarily in the late 1990's and early
2000's and consisted of cured -in -place sewer lining and manhole lining and replacement. Additionally the
main outfall lines extending from N. Honeycutt Street to the Wastewater Treatment were rehabilitated
and manholes were raised above the flood elevations. Rehab of the existing sewer and manholes did
reduce the Town's I&I problems; however, the Town is still experiencing issues with continued aging of
sewer infrastructure. These problems are detailed in the sewer system evaluation portion of the AMP.
3.1.1 WASTEWATER TREATMENT PLANT
The Town of Benson owns and operates a 1.9 MGD extended aeration type wastewater treatment plant
(WWTP). The treatment facilities consists of flow equalization lagoons, an arc bar screen, a flow meter,
grit removal, an influent screw pumping station, three (3) aeration and oxidation ditches, five (5)
clarifiers, chemical (alum) addition for phosphorus removal, a filter lift and return sludge pump station,
tertiary filters, chlorination, dechlorination, post aeration, lime storage and feed, an effluent flow
measurement with composite sampler, an aerated sludge lagoon, a lagoon effluent pump station, and a
backup generator. Sludge is discharged into a concrete aerated sludge holding basin for stabilization and
storage, prior to land application. Treated effluent is discharged to Hannah Creek, a tributary to the Neuse

River. When needed, some treated wastewater is routed to the reuse system where it is used for irrigation
at the South Johnston County High School and on the treatment plant site.
The Town's average wastewater flow from January 2016 to December 2017 was 0.95.MGD. The Town
of Benson Wastewater Treatment Facility operates under NPDES Permit No. NC 0020389, reissued and
expired April 30, 2018. The Town currently has an application on file with the Division of Water
Resources for the permit renewal.
No improvements projects to the WWTP are currently proposed; however, the Town should pursue
improvements to the WWTP in the future to address aging equipment and components. The Town may
also benefit from evaluating its future needs to ensure that the WWTP has adequate capacity for expected
future growth.
3.1.2 WASTEWATER PUMPING STATIONS
The Town of Benson currently has eleven (11) pumping stations as listed below:

3.1.3 GRAVITY SEWER COLLECTION SYSTEM
The gravity sewer system consists of approximately 34.97 miles of gravity sewer ranging from 6 inches to
24 inches in diameter. Table 3.2 shows the length of pipes of each diameter:

The first section of sewer system, which was constructed in the 1930's, served the central and northwest
section of Town, north of the railroad tracks. The sewers serving the section south of the railroad were
constructed in the 1940's. These sewers were constructed with clay pipe and masonry manholes
constructed mainly with brick. The majority of the sewer was constructed with 2 to 4 foot long segments
of vitrified clay pipe and Oakum type joints. These types of joints tend to decay away over a period of
years making the sewers susceptible to infiltration during high groundwater conditions. The newer areas
of the sewer system have been constructed with precast concrete manholes and primarily with PVC
plastic pipe. The integrity of the newer portion of the Town's system is far superior to that of the older,
although both portions of the Town's system need ongoing inspection and maintenance as they age.
In the past, the Town has pursued rehabilitation of a portion of its existing sewer system to remedy its
sewer I&I problems. It is estimated that approximately 45,000 LF of the Town's gravity lines (which
represents around 24% of the gravity lines) have been rehabilitated. This rehabilitation occurred primarily
in the late 1990's and early 2000's and consisted of cured -in -place and fold and form sewer lining;
manhole lining and replacement; point repair; and pipeline replacement. Additionally the main outfall
lines extending from N. Honeycutt Street to the Wastewater Treatment were rehabilitated, with manholes
on this outfall raised above the flood elevations. Rehab of the existing sewer and manholes helped to
reduce the Town's I&I problems; however, the Town is still experiencing issues with continued aging of
its infrastructure.
3.1.4 USER CHARGES
The Town of Benson charges its user a Base Charge and a variable charge per 1,000 gallons of use.
Customers are all charged the same rate regardless of whether they are residential, commercial, industrial,

or institutional customers. The only variance in customer rates is due to the fact that those customers
located inside town limits are charged less than those outside the town limits. Table 3.3 shows the number
of each type of customers, while Table 3.4 compares the in -town rates to the out-of-town rates:

3.2 PRESENT CONDITION
The Town has undertaken a long range planning program to evaluate their sewer system. The project
consisted of mapping the system, visually inspecting the manholes, smoke testing the gravity collection
system, inspecting selected sections of the system by CCTV, visual inspections of sewer pumping
stations, hydraulic modeling of the existing system, flow monitoring of individual drainage basins, and
infiltration and inflow analysis of the system as a whole. The detailed report on these findings can be
found in the Asset Management Plan. The general condition of the system ranges from good to fair to
poor. The newer parts of the system are good and the older parts are fair and reaching the end of their
useful life. To maintain status quo the Town should continue to improve the system, using its current
maintenance plan and any additions to its operations and maintenance as recommended by the AMP, and
should correct deficiencies on a proactive basis. Accordingly it will be necessary to prioritize the work
and schedule it over a 10 year period. The following sections detail the work recommended by the AMP
and set a 10-year planning schedule for the Town's use.

4. PROJECTS IDENTIFIED IN ASSET MANAGEMENT PLAN
4.1 SYSTEM NEEDS
In 2012 the Town began a multi -phase, multi -year project to develop a long range plan to assess its
wastewater system needs by identifying deficiencies in a systematic and comprehensive manner. An
Asset Management Plan, this CIP, and an Operation and Maintenance manual for the Town's wastewater
collection system were all created as the final phase of the project. An inventory and map of the sewer
system, a condition assessment for the manholes and piping systems (through survey, smoke testing, and
CCTV inspection), and a condition assessment for the Town's eleven sewage pumping stations were
completed, all with the purpose of identifying possible weaknesses in the system and potential locations
for improvements projects. Additionally, the capacity of the system was modeled in an effort to identify
specific areas with present capacity issues.
The capital outlay needs have been identified using the information obtained from these assessments and
are prioritized to develop a Capital Improvements Plan the Town can adopt as a guide for planning and
budgeting.
4.2 MANHOLE REHABILITATION
Inspection of each manhole within the wastewater collection system was located, opened and inspected.
Manholes were accessed of physical condition during the inventory process. Of the 634 manholes
surveyed, 199 of them had one or more notable defect. Of those, 67 had two notable defects, and of those,
19 had three notable defects. Defect types include the following:
• Corrosion;
• Cover buried;
• Damages to the channel, cover, frame, ring, or wall;
• Grease present;
• Infiltration present;
• Invert leaking;
• Misaligned frame;
• Missing material;
• Odor present;
• Service leaking;
• Subject to flooding.
Town of Benson Wastewater Collection System 8
Capital Improvements Plan
December 2018 THE WOOTEN COMPANY

The AMP discusses the findings of the Manhole Inspection survey. The inspections identified
approximately 213 manholes that contained a defect that requires correction. The work proposed for these
manholes is included in the opinion of probable project cost. In addition, there are approximately 122
manholes that contained debris — the Town can address the debris in manholes without a contractor. In
addition, the Town indicated there are numerous manholes throughout their system that are brick
manholes whose bricks and mortar are failing. To address these manholes, a Find and Fix line item has
been added to the opinion of probable project cost.
Many of the defects noted in the cost opinion are minor repairs — add rain insert, add vented manhole
cover, or add new manhole cover. There are more significant repairs noted as well — replace or
rehabilitate the manhole, repairs to services, rims, channels, or inverts, or resetting or elevating the
manhole's rim or frame. The more significant repairs should be completed first to ensure the integrity of
the Town's wastewater system; then the minor repairs can be addressed. All of the defects noted are either
structural in nature or will correct an inflow source of I&I that is rainfall dependent. This work is
scheduled to occur in FY2018/19, FY2019/20, and FY2020/21 to allow for opportunities to obtain
funding and contracting the work. The opinion of probable project cost to complete the repairs suggested
by the survey in FY2018/19 and FY2019/2020 (major repairs) and FY2020/21 (minor repairs) is
$934,200.

4.3 WASTEWATER PUMP STATION REPAIRS
Nine of the Town's wastewater pumping stations were inspected as part of the AMP preparation (the two
new stations installed by the Town in 2017 were not inspected). The inspection evaluated the pumping
stations using the minimum design criteria currently practiced by the NCDEQ. Deficiencies from these
criteria were noted and cost estimates to bring the stations to the current design standards were prepared.
One pump station (Wall Street) will be fully replaced with a brand new station, as its age, location, and
susceptibility to flooding indicate the need to have it replaced. In the remaining older pump stations, the
primary deficiency noted was a lack of standby generators. The opinions of probable cost for West Ridge,
Lake Shore, Boardwalk, Burris, and King Circle show the addition of a standby generator. The stations
not receiving them have generators less than 15 years old that do not need replacement.
There were six pump stations that need their wet wells to be lined and/or cleaned, and there were a
number of minor maintenance items that need to be addressed at all nine older stations. Additional
maintenance items needed have been noted and costs were included for labor intensive items. The overall
opinion of probable project cost for the necessary upgrades to the Town's pump stations, as shown on
Table 4.2, is estimated to be $844,100 (project scheduled for FY2021/22). Individual project opinions can
be found in Appendix A.

4.4 SEWER LINE REPLACEMENT AND REHABILITATION
4.4.1 SMOKE TESTING AND CCTV INSPECTION
Smoke Testing and CCTV of the sewers further identified defects in the gravity sewer system that require
repair. Smoke testing primarily identifies areas of smoke egress which directly connect into the sewer
lines. For example, if rainfall is puddling in an area of egress or if a catch basin shows evidence of
smoking during the smoke test, rainfall can flow directly into the sewer causing RDII. Additionally, as
the sewer line between manholes is being inspected by CCTV, defects can be identified. Examples
include holes in piping, a steel rod driven through a sewer pipe, gas lines installed through a sewer pipe,
multiple locations where the water level in the pipe sages due to the pipe settling over time, and leaky old
joints. All of these defects contribute to an increase in I&I. With the analysis completed, multiple
projects have been defined to correct these deficiencies. A detailed report on these tasks is available in
the Asset Management Plan. The projects identified are as follows:
• Replacing 8-inch gravity sewer lines with holes in the pipes (two locations);
• Replacing 8-inch gravity sewer lines prone to infiltration;
• Upsizing 6-inch gravity sewer lines to 8-inch lines, which will address capacity issues evidenced
by a significant water mark on the pipes;
• Replacing 8-inch gravity sewer lines that have become corroded and filled with debris;
• Replacing 8-inch gravity sewer that has become deformed and is prone to infiltration;
• Completing numerous point repairs to address undersized pipe, corrosion, liner issues, roots, taps,
or other objects protruding into the pipe, cracked and fractured pipes, and debris -filled pipes.
The full scope of these projects is fully explained in the CCTV inspection section of the AMP. The first
project will be completed in FY 2018/19, and entails replacing multiple segments of 8-inch gravity sewer
and completing multiple point repairs. This work, along with the work described in section 4.4.2, has an
opinion of probable project cost of $797,950. Additional projects to address the deficiencies noted above
are scheduled for FY2019/20, FY2020/21, FY2021/22, and FY2022/23. The overall opinion of probable
project cost for all work described in this section is estimated to be $1,843,300. Table 4.3 shows the
opinions of probable cost for the projects derived from CCTV inspection and smoke testing. Individual
project opinions can be found in Appendix A.
4.4.2 HYDRAULIC MODELING
Hydraulic modeling was completed on the Town's system. The hydraulic modeling was completed using
customer billing and flow data from the past three years to quantify the flow throughout the system. The
model showed one location where the pipes are nearing full capacity due to decreased diameter and slope.
Town of Benson Wastewater Collection System 13
Capital Improvements Plan
December 2018 THE WOOTEN COMPANY

These 8-inch lines should be upsized to 10-inch lines to provide more capacity and to ensure that
increased commercial and industrial development will not cause a sanitary sewer overflow. More
information regarding this project can be found in the hydraulic modeling section of the AMP. The
opinion of probable project cost of this work is estimated to be $736,700 (project scheduled to be
completed in FY2023/24). Table 4.4 shows the opinions of probable cost to address what was found in
modeling analysis.
In addition, the model confirmed the presence of capacity issues that have led to SSOs which occurred
during significant rainfall events. At the intersection of U.S. 301 and W. Martin St., manhole E001
accepts flow from an 8-inch line and a 15-inch line. The outlet pipe for this manhole is a 10-inch line that
flows into a 12-inch line before reaching the Town's 15-inch outfall line. The model indicated that the 10-
inch line is between 50-75% capacity during the Wet Weather Maximum Flow scenario. Town officials
have noted multiple significant -volume SSOs that have occurred at manhole E001 in the past 3 years,
which suggests that the 10-inch line flowing out of this manhole cannot handle the volume of flow that
reaches it during significant rainfall events. Accordingly, the Town plans to replace the existing 10-inch
and 12-inch lines with 15-inch gravity sewer. This project will be completed in FY2018-19 as part of the
Hurricane Matthew grant received by the Town (see section 4.4.1 for the remainder of the project
completed using this grant funding). The opinion of probable project cost for the entire project is
$797,950.
4.4.3 FIND AND Fix REPAIRS
As the operator of a large and aging wastewater system, the 'Town should proactively plan for unforeseen
repairs to its system, in both its collection system and at its pump stations. It is advised for the Town to
undertake a Find -and -Fix repair project every 3 years such that the Town is completing repairs to its
system as they present themselves. If problems do not present themselves, the Town can proactively
address its older sections of Town to prevent a future problem from occurring. As the extent and contents
of these projects will not be known until they are ready to be executed, a detailed opinion of probable cost
has not been developed. Rather, for budgeting purposes, a budget cost of $500,000 has been added to year
3 of the 10-year calendar, and a cost of $1,000,000 has been added to years 6 and 9 of the 10-year
calendar.

4.5 DECOMMISSIONING BOARDWALK AND LAKE SHORE PUMP STATIONS
Previous studies have identified the decommissioning of the Boardwalk and Lake Shore pump stations as
a potential future project to improve operational efficiency and reduce costs. These stations are currently
fully operational, and while minor maintenance issues occur periodically, no major repairs should be
expected in the foreseeable future. The stations receive wastewater from residents in the Boardwalk and
Lake Shore subdivisions and discharge the wastewater ultimately to the Town of Benson WWTP. As they
are functioning correctly, abandonment is not a matter of necessity, but rather of increasing the Town's
efficiency and increasing the system's reliability.
The Boardwalk pump station and Lake Shore pump station are located within a tenth of a mile of each
other, and the Lake Shore pump station is at a much lower elevation than the Boardwalk pump station, so
extending gravity sewer from the Boardwalk pump station to the Lake Shore pump station is feasible.
Furthermore, an existing gravity sewer line located in the existing utility easement east of W. Hale Street
is also at a lower elevation than the line entering the Lake Shore pump station. Accordingly, all of the
wastewater generated by residents currently served by both the Boardwalk and Lake Shore pump stations
can be fed into the W. Hale St. sewer line while still meeting the minimum gravity sewer slope
requirements established by the NCDEQ wastewater permitting section. Decommissioning these pump
stations removes the operation and maintenance costs that will be incurred while they are still in service.
Decommissioning the Boardwalk and Lake Shore pump stations fits into the Town's long-term plans. By
removing these stations and extending the gravity sewer lines from these stations to existing services, the
Town makes its infrastructure more efficient, and easier to maintain. Additionally, the fiscal and
manpower burden involved in maintaining these stations is removed, and the Town can more effectively
allocate its resources. The opinion of probable project cost shown below indicates the expected project
cost to complete the decommissioning of these two pump stations is approximately $1,352,200 (project
scheduled for FY2028/29). Design for these projects was completed as part of a 2016 USDA project
undertaken by the Town. However, it will need to be updated to reflect any changes in existing
conditions. Accordingly, engineering design fees are still included in this opinion.

4.6 WASTEWATER COLLECTION SYSTEM LONG RANGE MASTER PLAN
Past experiences when working with smaller towns like Benson has shown that towns similar to Benson
have benefitted from having a master collection system plan. Normally, growth in towns of Benson's size
occurs in two ways. One form of growth comes through creating a higher population density in terms of
customers per acre. New customers occupy previously platted lots and fill in vacant lots in subdivisions
and within the older parts of town. The other form of growth occurs through new residential and/or
commercial developments in which the sizing and general location of sewers will be determined by the
developer. Collector lines are typically 8 inch diameter and follow streets and roadways within the
subdivision. The collector lines then will need to connect to the Town's sewer to flow to the WWTP.
With proper planning, the Town can take advantage of the new development's plan by working together
to build a system that will meet the Town's future needs. To best meet these needs and to develop a
robust partnership with the developer(s) that may choose to build in the Town, the Town should have a
well thought out master plan available to the developer(s) at the beginning of the planning stage.
Additionally, having completed the inventory mapping of the existing system and the hydraulic analysis
of the present conditions of the system, an efficient master plan can be developed. This plan should
include projecting future growth into the system. The hydraulic model can be modified to show increased
demands from new subdivisions, other residential growth, or increased commercial/industrial growth. The
Town can then see where capacity issues are seen as growth comes to the Town. The opinion of probable
project cost to create a long-range master plan is $40,000, as shown in the 10-year calendar.

5.2 SCHEDULING OF COLLECTION SYSTEM NEEDS
The Town has undertaken a long range planning program to evaluate the existing conditions of its sewer
collection system. The project consisted of mapping the system, visually inspecting the manholes, smoke
testing the gravity collection system, inspecting selected sections of the system with CCTV cameras,
visual inspections of sewer pumping stations, flow monitoring and infiltration and inflow analysis of the
system as a whole, and hydraulic modeling of the existing system. The detailed report on these findings
can be found in the Asset Management Plan. The general condition of the system ranges from good to
fair to poor. The newer parts of the system are good, while the older parts are in fair condition and are
reaching the end of their useful life. To maintain status quo the Town should continue to improve the
system, using its current maintenance plan and any additions to its operations and maintenance schedule
as recommended by the AMP, and should correct deficiencies on a proactive basis. Accordingly it will be
necessary to prioritize the work and schedule it over a 10 year period.
The projects have been scheduled based on their priority ranking. The table below indicates the proposed
schedule. Annual smoke testing and cleaning of the sewers, Capital Outlay reserves, and a triennial Find -
and Fix Capital Repairs project are included in addition to the projects identified in the AMP to show a
complete picture of the overall annual costs suggested for future planning. All unit costs in each opinion
of probable project cost were created with 2019 bid pricing; however, all of these projects will not be bid
in 2019. Accordingly, a 3% per year inflationary figure has been added to each project, depending on the
year the project is scheduled to bid.

6. FUNDING PROGRAMS
The Town of Benson will continue to improve its Wastewater Collection system as funding becomes
available. The Town plans to pursue this funding as it becomes available to fund its capital improvement
needs. Below is a list of different potential funding sources that may be able to assist the Town in
reaching these goals. These funding agencies have different submission deadlines for applications for
funding; accordingly, it is important that these submittal deadlines are taken into account when planning
the project timeline. A combination of these agencies can be used to help the Town's complete the
projects described in the AMP and those that present themselves in the future.
• The United States Department of Agriculture (USDA) can provide loans with 40 year terms and
low interest rates. USDA has a Rural Development branch which funds rural communities with
populations of less than 10,000 people. Often the funds can be awarded in loans and grants to
further assist the town in the project financing. The Town of Benson may qualify for grant
funding through USDA, as its 2016 Median Household Income (MHI) of $30,918 is well below
the N.C. average of $48,256 (according to the 2016 Local Government Unit Parameters — updated
2/2018). This MHI value also affects the interest rate available for payback on a loan from
USDA. Other factors, such as sewer rates and fund balance, could affect the amount of grant
money the Town is eligible for and ultimately receives. USDA accepts loan and grant
applications on a rolling basis.
• The Town of Benson is also eligible for Community Development Block Grant (CDBG) funds,
due to its rate of Low to Moderate Income (LMI) households of 79.54%. This grant source will
fund wastewater infrastructure projects such as those listed herein. The maximum grant available
through this program is $2,000,000. CDBG grant application deadlines are in the fall of each
year.
• The Division of Water Infrastructure section of the North Carolina Department of Environmental
Quality has loan and grant programs specifically for sewer. The Town would be eligible for
Clean Water State Revolving Fund (CWSRF) funds, a low interest loan for local government
units. This funding program would help with any of the wastewater collection projects described
in this document. Loan terms are typically 20 years, with low interest rates available. This
funding source has two application deadlines — one occurs in the spring of each year, and one
occurs in the fall of each year.
• The Golden LEAF Foundation provides grant funds for rural and/or economically distressed
towns. These funds are designed for projects that build economic opportunities in towns like
Town of Benson Wastewater Collection System 25
Capital Improvements Plan
December 2018 THEW001ENCOMPANY

Benson. The Town could use these funds in any of the projects described above. Like USDA,
Golden Leaf applications are accepted on a rolling basis.
Should loan grant funds be unavailable or inadequate for the projects the Town wishes to pursue, it is
possible for the Town to use local funds or obtain a private loan. In this case, the Town should give
careful consideration to adjusting water and sewer rates so that in addition to maintaining sufficient cash
flow for routine operation and maintenance, sufficient funds are set aside for purposes of undertaking the
necessary capital improvement projects.
