See ... City of Tallahassee v. Elliott, 326 So.2d 256 (Fla. 1st DCA 1975), cert, denied, 344 So.2d 324 (Fla.1977) (maintenance of drainage system).” Trianon, 468 So.2d at 920-21; accord Avallone v. Board of County Comm’rs of Citrus County, 493 So.2d 1002 (Fla.1986). Therefore, having undertaken to operate the sewer system, the City owed a duty to maintain the pumps in a non-negligent manner. See, e.g., City of New Smyrna Beach Utilities Comm’n v. McWhorter, 418 So.2d 261 (Fla.1982) (<HOLDING>); see Bray v. City of Winter Garden, 40 So.2d
