In 1988, some members of the Select Society of Sanitary Sludge Shovelers (5S), who were also members of the Institution of Water and Environmental Management (IWEM; chartered in 1995, now CIWEM), founded the Guild of Water Conservators.
Its petition for livery was granted by the Court of Aldermen with effect from 2000.
The supporters of the Company's coat of arms consist of a beaver and an otter.
Each of them is holding a golden shovel to recognise the part played by the British chapter of the 5S (whose badge is a golden shovel) in the formation of the guild.
