SUBJECT: Proposed 2" Low Pressure Sanitary Sewer to Serve Snug Harbor Road
Mecklenburg County, NC
CLTWater Project No.: DNC-60-21-194
To Whom It May Concern:
Charlotte Water is requesting approval to extend a proposed public 2-inch low pressure sewer system to serve
an existing single-family neighborhood located on Snug Harbor Road in North Carolina. The extension will
consist of approximately 1002 LF of 2-inch low pressure sanitary sewer along Snug Harbor Road. The proposed
2-inch low pressure sewer will discharge into an existing 2-inch low pressure sanitary sewer main located on
Snug Harbor Road. The existing 2-inch low-pressure sewer main was constructed in 2020 and discharges into a
gravity sewer manhole located approximately at the intersection of Snug Harbor Rd & Hawkwatch Lane. The
collection and disposal system will be owned and operated by Charlotte Water (CLTWater). This extension is
part of Charlotte Water's extension policy (Chapter 3 of the approved Charlotte Water Design Manual).
Charlotte Water has agreed to accept the flow generated by this sewer extension.
Installation and maintenance of the pump and wet well will be the responsibility of the property owner.
CLTWater will provide information to the homeowner regarding requirements for construction and will inspect
wet well and pump following installation to ensure compliance with CLTWater standard specifications prior to
connection to the new 2" LPSS.
This package includes:
• Cover Letter
• Application ASEA 04-16
• Form FTSE 10-18
• Site Maps — 2 Copies
o USGS Topographic Map (8.5"xll")
o Vicinity Map (83"xll")

RE: Charlotte -Mecklenburg Utility Department
Reduction in Wastewater Flows
Mecklenburg County
Dear Mr. Gullet -
On July 20, 1994, the Division received your wastewater flow reduction request and support
documentation concerning wastewater flows associated with the entire Charlotte -Mecklenburg Utility
Department service area. Your letter requested the Division allow the reduction of wastewater flows from
250 GPD per dwelling unit which was previously approved in accordance with Forth Carolina
Administrative Code, to 190 GPD per dwelling unit for single family residential areas and 135 GPD per
dwelling unit for multi -family residential_ areas. In support of your request, documentation was provided
from the existing Irwin, Sugar, and McAlpine Creek wastewater treatment plant service areas.
The documentation provided in support of the flow reduction request was compiled by Camp
Dresser & McKee starting in late 1990 and is currently ongoing. Data submitted to the Division was not in
strict accordance with 15A NCAC .0219(l)(3), however, in view of the submitted documentation,
adequate justification was provided in support of the wastewater flow reduction request. The work
completed by Camp Dresser & McKee consisted of tracking base wastewater flows, groundwater
infiltration, and rainfall -dependent infiltration/inflow for the Irwin, Sugar, and McAlpine Creek
wastewater treatment plant service areas. Data was collected from 106 flow monitors (both permanent and
temporary) and 14 rain gauges during November and December 1991 located along major sewer trunklines
within the study area. Existing dry -weather flows were developed for each of the three (3) wastewater
treatment plant service areas which included groundwater infiltration. The service area dry -weather flow
estimates were further broken-down into thirteen (13) drainage basins. These revised dry -weather flow
estimates were compared to land -use based flow estimates developed using existing land data for 446
Origination and Destination (O&D) planning zones as provided by the City of Charlotte's Department of
Transportation. From this comparison the revised wastewater flows were developed. Although these
numbers were developed for Irwin, Sugar, and McAlpine Creek service areas, the results would also be
applicable to txnth the Mallard Creek and McDowell Creek wastewater treatment plant service areas.
In view of the information submitted, the Division of Environmental Management will allow the
use of 190 GPD per dwelling unit for single family residential areas and 135 GPD per dwelling unit for
multi -family residential areas on all applicable non -discharge permit applications for future wastewater
collection extensions which will be made tributary to all five (5) Charlotte -Mecklenburg Utility Department
wastewater treatment facilities. This consideration applies to any applicable future projects submitted to
this Division as well as any projects which are presently under review. Wastewater flows presently
tributary to the wastewater treatment facilities can be adjusted upon negotiations between the Charlotte -
Mecklenburg Utility Department and the Division's Mooresville Regional Office.

The Division does have concerns regarding the proposed sewage flow rates with respect to
infiltration and inflow. Although the 190 GPD per dwelling unit for single family residential areas and
135 GPD per dwelling unit for multi -family residential areas are justifiable flow rates, the Charlotte -
Mecklenburg Utility Department has in essence reduced the safety factor typically associated with
infiltration and inflow. The flow rate established by the Division does allow for some infiltration and
inflow. The Division is of the opinion that proper wastewater collection system management is more
effectively and efficiently accomplished by the entity that is accountable for ensuring overall compliance
with all aspects of wastewater collection, treatment, and disposal requirements. In this view, we look
forward to continued progress by the Charlotte -Mecklenburg Utility Department to fully assume the
wastewater collection permitting program_

Subject: Variance Modification
Separation Distance from Wells
Small Diameter Pressure Lines
Dear Mr. Shearin,
The Non -Discharge Permitting Unit has completed a review of the subject variance issued
April 13, 2000. Following this review and discussions with engineers involved in projects in
Mecklenburg County, a modification to the original variance is being approved.
A variance is granted for the use of SDR 13.5 PVC pipe in lieu of Ductile Iron Pipe within the
25-ft to 100 ft. radius of private wells for pipe sizes where ferrous pipe is not available regardless of
whether one or more wells are involved. Note that the previous variance approval was for where
multiple well radii overlap, The line within the well radius must be tested to water main standards
with zero leakage and a detector tape shall be placed over the pipe. Service lines should be routed as
far as practicable from the well(s). These conditions must be included as notes on the plans each place
that this variance is exercised.
Approval of this variance is granted only for situations where there is no other feasible location
for the sewer line.
if you have any questions regarding this request, please call Bennie Goetze, Jr., P. E., at (9I 9)
733-5083, extension 375, or Marie Doklovic, P. E., at [phone] extension 371.

III. Certification Statement:
Keri Cantrell
certify to the best of my knowledge that the addition of
the volume of wastewater to be permitted in this project has been evaluated along the route to the
receiving wastewater treatment facility and that the flow from this project is not anticipated to cause any
capacity related sanitary sewer overflows or overburden any downstream pump station en route to the
receiving treatment plant under normal circumstances, given the implementation of the planned
improvements identified in the planning assessment where applicable. This analysis has been performed
in accordance with local established policies and procedures using the best available data. This
certification applies to those items listed above in Sections I and II plus all attached planning assessment
addendums for which I am the responsible party. Signature of this form certifies that the receiving
collection system or treatment works has adequate capacity to transport and treat the proposed new
wastewater.
