Between 2010 and 2015 Southern Water illegally dumped sewage into our rivers and sea 6971 times. With human waste flowing into the sea around Brighton regularly, our sewage system has not improved since Victorian times - it has deteriorated.

Using printing techniques that were discovered in the 1800s (whilst Brighton’s first sewers were being built), This Septic Isle features prints that have been developed using the salt type method, using dirty seawater collected from the beaches around Brighton.

Looking at both the private company responsible for our sewage problem and the activists trying to fix it, This Septic Isle explores the UK’s relationship with the sea and how it got so dirty.
