Our mission statement:

To research, set standards and disseminate best practice in UK siphonic drainage, from design to installation.

Siphonic drainage was first introduced in the 1960's in Scandinavia and since then has been used widely across Europe, including the UK, in the Far East, Australasia, South Africa and the USA.. Many large industrial, commercial and retail buildings are now fitted with siphonic drainage, which has clear advantages over gravity drainage.
