The existing lot has one (1) existing 5,006 sf medical/retail building and one (1) proposed 5,154 sf medical/retail. Sewer flow to be generated by the proposed building will add 1,835 GPD.(please see the attached calculations) to the previously approved Rea Road Mixed Use Development Phase 1 Sewer Extension (WQ0022105). The sewer collection system within the project site will be provided by a series of 8 inch gravity lines owned and maintained by Union County Public Works (UCPW). The proposed sewer system will tie into existing downstream 8 inch sewer lines (Permit #WQ0031776) owned by UCPW and will be treated at McAlpine Creek WWTF (WWTF NC0024970), which is owned by Charlotte Water.

This acceptance of flow is based upon the existing capacity of the designated publicly owned treatments works. Please see attached NC DEQ FTSE form. The applicant should understand that due to the involvement of other agencies and continuing growth of the water and sewer system, the ability to provide service for future projects cannot be guaranteed nor reserved. Connection to the CLTWater and sewer 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 (2) years of issuance of this flow acceptance and payment for any service connections have not been received within (2) years of issuance of this flow acceptance letter, this flow acceptance approval shall be rescinded and a new flow acceptance request must be made.
