Re: Charlotte Water — Mallard Creek WRF Trailer & Parking Improvements Phase 2
Gravity Sewer System Fast Track Application
Dear Reviewer:
On behalf of our client, Charlotte Water, Gavel & Dorn Engineering, PLLC (G&D) is pleased to
submit the following documents for review relating to the Mallard Creek WRF Trailer and Parking
Improvements Phase 2 Project:
• (1) Check for application fee in the amount of $480.00;
• (2) Copies of Fast Track Application and supporting documentation.
Charlotte Water will be constructing a new 8-inch sanitary sewer main to service construction
trailers located near the Mallard Creek Wastewater Reclamation Facility in Charlotte, NC. Total
new private sanitary sewer main to be constructed is 513 LF. The flow will discharge to a public
sewer maintained by Charlotte Water that is then directed to the Mallard Creek Wastewater
Reclamation Facility.
There will be 10 total office trailers and estimated 65 employees in the trailers. New sewer flow is
based on the assumed 65 employees. Total permitted flow will be 1625 GPD.
Please contact me at 704.724.5047 if you need any additional information for your review.
Sincerely,
GAVEL & DORN ENGINEERING, PLLC
Sean Mayo, P.E.

FLOW TRACKING ACCEPTANCE FORM (FTSE 08-13)

CHARLOTTE

Mrs. Tesha Okioga
Charlotte Water
5100 Brookshire Boulevard
Charlotte, NC 28216
SUBJECT: WATER AND SEWER FLOW ACCEPTANCE
MALLARD CREEK WRF PHASE 2 TRAILER AND PARKING IMPROVEMENTS
12330 NORTH TRYON STREET, CHARLOTTE, NC 28262
CLTWATER TRACKING# 2021936
After an analysis of the sanitary sewer associated with the proposed design of project, 2021936,
MALLARD CREEK WRF PHASE 2 TRAILER AND PARKING IMPROVEMENTS, it was determined
that there is sufficient capacity to accommodate the proposed sewer flow of 1,625 gallons per day
(65 emp x 25 gpd/emp) at the connection point(s) indicated on the submitted utility plan for
transmission to the Mallard Creek Wastewater Treatment Plant; NPDES permit number
NC0030210, for treatment. This acceptance of flow is based upon the existing capacity of the
designated publicly owned treatments works. Please see attached NCDEQ-FTSE form.
Charlotte Water (CLTWater) agrees to furnish water to the subject project. The water quality to the
subject project is regulated by the State Drinking Water Act Amendments of 1986 and The Water
Supply Management Plan, PWS ID # 0160010 on file with the Public Water Supply Section of
NCDEQ. However, CLTWater cannot guarantee a constant pressure or quality of flow.
The applicant should understand that due to the involvement of other agencies and continuing
growth of the water system, the ability to provide service for future projects cannot be guaranteed
nor reserved. Connection to the CLTWater system is accepted on a first come first served basis.
The applicant should understand that this letter is not authorization to construct or extend private
water or sewer systems, as the appropriate local or State permits are required prior to construction.
If the appropriate authorization to construct permits are not obtained construction has not started
within two (2) years of issuance of this flow acceptance, and payment for any service connections
have not been received within two (2) years of issuance of this flow acceptance letter, this flow
acceptance approval shall be rescinded, and a new flow acceptance request must be made.
The CAP analysis performed determines available capacity within the existing public gravity sewer
system. The developer is responsible for any additional private or public sewer infrastructure
required to convey flow from the proposed development to the existing public gravity sewer.
If you have any questions, please do not hesitate to contact me at [phone].

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.
