Asset Management Plan (AMP): In March 2013, the Asset Management ;Plan report was
completed ($115,000) by Kurt D. Wright, P.E. (828-245-4080). This Plan promotes
proper stewardship of municipality owned infrastructure and qualifies the Town of
Spindale for grant funds and/or low interest loans. 2012 Sanitary Sewer Replacement
Project: $ 882,000 (NCDENR Project ,No. CS370621-03) was done to replace aged lines
and reduce infiltration and inflow (I&I). The average rain event;contributes 250,000
gallons per day of I&l. We are still in the process of updating this asset 'management
plan and updating our sewer system map with any changes orlmanhQ findings. We _
have also purchased a recycling container to collect mercurytitems from town
residents to prevent any mercury items being- placed in the sewer system. The Town is
has finished (Main Street Spindale Rehab) We have replaced 885 feet of 8" sewer line
and four new manholes in this project from Main St Spindale and Nebraska St. We have
also presented to the Town of Spindale Board of Commissioners to do a rehab on our
Oak St Pump Station at 683 Thunder Rd Rutherfordton, ,NC 28139 and vas granted the
funds to do so along with grants. In 2020 We started the rehab !on our Oak St Pump
Station and work has been completed, we added two new dry pit submergible pumps
and two new control boxes, also new (PLC). We have received the funds and currently
in the process of Getting the permits to rebuild Oak St pump station and making it into
a tri-plex Submergible Station with new wet well. Oak St Pump!station project will be
breaking ground this ,year 2023 to rebuild Oak St Pump Station.
sanitary sewer System blow monitoring Stuay:
The Town of Spindale has Completed the flow monitoring study. We are currently
in the process of smoke testing and die testing in our Basins A-2 and s�ubbasins (A2-4
and A2-6) also'Basin A2-1. We are working Diligently to eliminate the inflow and
infiltration (I&I) in our system. The Town of Spindale is still in the process of smoke
and die testing currently.
Pioe Condition Assessment (PCAP)- (AIA) Study
The Town of Spindale received a (AIA) Grant for-$150,000 from" the NC Division of Water
Infrastructure under the asset inventory and assessment (AIA) Program (AIA GRANT
DWI # E-AIA-W-21-0232). The PCAP was conducted for the sanitary sewer basins
prioritized by the Town of Spindale's 2018 "Sanitary Sewer System Flow Monitoring
Study" (SSFM) In basin Al & A2. The goal of the project was to identify; sources of
inflow and infiltration (Ill) within the targeted basins of the waste water ;col lection
system and to make recommendations for remediation and repairs. Smoke testing,
Closed circuit tv (CCTV),and visual Observations of the methofds were utilized to
identify specific areas where groundwater or stormwater may be entering the sewer
system. The Town of Spindale has also received a $400,000 (AIA) grant to update the
Asset Management Plan and do more (CCTV) and Smoke Testing this grant is from NC
Division of Water Infrastructure (DWI). The Town of Spindale also applied fora
Construction Grant for $6,390,260.00 in September 2022, this will be a result of our
(AIA) Pipe Condition Assessment (PCA) of basins Al & A2.

Scope and Purpose
SDG Engineering, Inc. (SDG) has completed a sanitary aewer system flow
monitoring study for The Town of Spindale. The study, which encompassed 19 flow -
monitoring locations, was performed from April 2017 through March 20,18. The study
was funded by Asset Inventory and Assessment (AIA) grant from the N.C. Department
of Environmental Quality, Division of Water Infrastructure. The Town of ;Spindale was
Granted $142,979.68 to this project, by (AIA), also The Town of;Spindale also
contributed $7,020.42 of the cost also to make up a total of $15,0,000.00 itoward the
project. Labella Associates HACH Preferred Data Delivery Services (PDDS) were major
contributors to this project.
The goal of the study is to help the Town of Spindale reduce the unusually high
peak rain induced flows the sanitary sewer collection and conveyance system (S.S.
System) is currently experiencing.
The report hereinafter discusses the purpose,, process, and results of a nine -
month inflow and infiltration study. The study makes the following recommendations.
1. Field investigate Basin A-1 via smoke testing, dye testing, and closed circuit
television (CCTV) to determine the cause of the flow variance. 'Defficiencies
should be corrected.
2. Field investigate Basin A-2 and its subbasins (A24 and A2-6) using the same
techniques described above. A24 was major contributor, of the total inflow and
infiltration (1/1) per inch of rain observed at the wastewater treatment plant
(WWTP).
3. Purchase two flow monitors (and corresponding data viewer subscriptions) and
continue to study Mega Basin A-3 to begin isolating areas with the greatest
inflow within the Basin._
4. Reapply for another AIA grant in three years to do a follow up study to isolate
more problem areas and to check progress on previous 'rehabilitation projects.
By following these recommendations, the Town will see a reduction of inflow at the
WWTP.
