The City of Tampa Water Department (city) currently owns and operates the David L. Tippin Water Treatment Facility (DLTWTF), which is permitted to withdraw an annual average quantity of 82 mil gal per day (mgd) and a maximum daily quantity of 120 mgd from the Hillsborough River. The overall goals of the DLTWTF are to provide safe drinking water by removing the vast majority of total organic carbon (TOC) in order to reduce formation of disinfection byproducts (DBPs), improve the aesthetic quality of the water by eliminating color, and reduce taste- and odor-causing compounds. Due to the DLTWTF’s raw water supplies, there is significant seasonal variability in water quality, specifically in regard to TOC, which has historically been as high as the low 30s (measured as mg/L).
