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 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.
