Croydon was one of the first towns to set up its own Board of Health in 1849. The Croydon Local Board of Health improved the water supply by building a pumping station, laying new water pipes, and building new sewers. The Board continued its work until 1883 and it appears that it was largely successful; by the 1890s Croydon was said to be “the healthiest among the large towns in the Kingdom.”
The number of Local Boards of Health in the UK peaked at 721 in 1873; however, it seems that Croydon was the only one to overprint its stamps.
