a. The proportion and amount of Obligated, Not Yet Tributary Daily Flow (C) accounts for

b. The rate of activation of this obligated, not yet tributary capacity is currently approximately

Steele Creek Pump Station Replacement and Relief Sewer is in design or under construction with
planned completion in Summer 2017 ; and/or
d. The following applies:
The Steele Creek Pump Station replacement project will provide a new regional facility capable of handling

expected completion in Summer 2017,
Therefore:
Given reasonably expected conditions and planning information, there is sufficient justification
to allow this flow to be permitted without a significant likelihood of over -allocating capacity in

Re: Proposed 2" Low Pressure Sanitary Sewer to serve 16408 MacGregor Lane,
Mecklenburg County, NC
CW:379-14-537
To whom it may concern,
Charlotte Water is requesting approval to extend an existing low pressure sewer system to
accommodate one new single family residential unit located off Grand Palisades Parkway
near Lake Wylie in the unincorporated part of Mecklenburg County, North Carolina. The
extension will consist of approximately 1200 LF of 2-inch pressure sewer along Grand
Palisades Parkway, Oleander Drive and through a utility easement that connects to
MacGregor Lane. The new pressure sewer will connect to an existing gravity sewer
system on Oleander Drive. The existing gravity sewer system located on Oleander Drive
drains to the Studman Branch Pump Station that is operated by Charlotte Water, formerly
known as Charlotte Mecklenburg Utilities..
This permit shall be for the 16408 MacGregor Lane parcel only. However the flow
acceptance form and design calculations have been completed with the assumption that
the 10 parcels located at MacGregor Lane will ultimately be connected to the low
pressure sewer system.
Construction of the new 2-inch Iow pressure sewer will be per CW standard
specifications which have been approved for use by NC DENR. CW will not construct
the actual wet well and pump but will provide information to the homeowner regarding
requirements for its construction. In addition, CW will inspect the wet well and pump
installation to ensure its compliance with CW standard specifications prior to allowing
connection of the service to the new 2-inch LPSS.
Installation of the pump and wet well is the responsibility of the home owner.
Maintenance of the pump and wet well will also be the responsibility of the homeowner.
Enclosed are the following documents for your review:
• (1) check for $480.00 (application fee);
• (2) copies sealed construction plans;
• (2) Project manuals (one with originals, one with copies) including the following:
o Alternative Sewer Extension Application (Form ASEA 10-14;
o Flow Tracking Acceptance Form (Form FTSE 08-13);
o I lxl7 Site Map;
o Engineering calculations;
o Customer information brochures;
• o Other required information.
