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been received within two (2) years of issuance of this flow acceptance letter, this flow acceptance approval shall be rescinded, and a new flow acceptance request must be made.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.
