The Bittell Reservoirs (grid reference SP017748) are located in Worcestershire between Barnt Green to the south and the Birmingham district of Longbridge to the north. They consist of the Upper (Upper Bittell) and Lower (Lower Bittell) reservoir. They were built to feed the Worcester and Birmingham Canal, which was finished in the 1790s, however, the reservoir was not completed until 1837. The 'Upper' reservoir is to ensure that the level of the canal is kept sufficiently high, even in times of drought. The 'Lower' reservoir(s) are compensatory reservoirs to ensure that the local area does not become parched in dry times.
