RE: Notice of Violation
NOV-2024-DV-0446
Permit No. WQCS00047
City of Sanford Collection System
Lee County
Dear Ms. Manuel:
We are in receipt of the above referenced Notice of Violation, received October 17, 2024,
which involved an overflow occurring September 16, 2024. The overflow took place
during Tropical Storm Helene and was attributed to Severe Natural Condition.
There are three projects in the area that should help this situation. (1) Little Buffalo
Rehabilitation — Upper Reach, (2) East Sanford CDBG, (3) Third St area sewer
Rehabilitation.
Little Buffalo Rehabilitation—Upper Reach.
This project is funded by a Clean Water State Revolving Fund loan of$3.8 million and
will be used to upsize the existing sewer interceptor to 18 inches. The project map,

Docusign Envelope ID:CE6D59C9-EC24-4520-B305-3D448CECE2C2
titled "Little Buffalo Interceptor Rehabilitation Project" is attached. It is expected to
upsize the line to Manhole 1960. This will increase the capacity of the interceptor
downstream of the subject location.
The project is being reviewed by the Division of Water Infrastructure. Once the City
has DWI approval, it will be bid. We expect bidding to take place in November of this
year.
East Sanford CDBG
This is a $ 2 million project that will cure-in-place line an area downstream of the subject
location. This is expected to reduce inflow and infiltration which will increase the
capacity of the existing interceptor.
Construction is currently underway with a completion date of June 2025.
Third Street area Sewer Rehabilitation
This project will cure in place line an area including the subject location. Please see the
attached exhibit labelled "Third Street Area Sewer Rehabilitation SSO/NOV". We
believe this project will decrease inflow and infiltration and increase the available
capacity of the line.
The City received a Letter of Intent to Fund from the Division of Water Infrastructure
this summer. We have started the procurement process for an engineer to assist us with
the work.
Should you have any questions, please feel free to contact me at any time.
Sincerely,
EDocuSigned by:
