Pollution Summary 2022

Here are all the reported sewage overflow totals for Controlled Sea in 2022. Sometimes sewage can be being dumped for months at a time.

These numbers are very slightly different from the Rivers page - This is because there is an invalid grid reference on the pollution consent - so we don't know where the CSO is. We're working on it.
