‘The smell wasn’t healthy’: the artist who wore 24 nappies to highlight sewage pollution – and fell ill

On the Deptford foreshore, a ghoulish figure is sinking into the Thames. Performance artist zack mennell (who writes their name in lower case) wades to their belly button as a crowd watches on. As they dip down further, their mutant costume – sewn together from 24 adult nappies – swells with water … and waste.

mennell’s work smears the personal and political across their body. The Thames performance is the finale of a project called (para)site, made in response to revelations of sewage discharge in our waterways and a reaction to the way benefit claimants are labelled as a drain on society. “OK,” mennell thought, “I’m going to be the parasite.” Their taking on of pollution was more literal than they intended; they contracted Weil’s disease from rat urine in the water.
