The fifteenth series of The Bill, a British television drama, consisted of 87 episodes, broadcast between 7 January and 31 December 1999. The series saw a notable change as female officers were no longer introduced by the W acronym in ranking, with the last mention of this when Liz Rawton was introduced as a WDC in Follow Through. By the following episode, Walking on Water, female characters were simply introduced as PC/DC etc. On 5 June 2013, The Bill Series 15 Part 1 & 2 and The Bill Series 15 Part 3 & 4 DVD sets were released (in Australia).
