Notes

Site is 250m upstream from Chobham Sewage Works which is currently undergoing major renovation works. The edges map shows it is currently spilling untreated sewage into this river (see screenshot)

Small (Sewage?) Pumping Station about 10m downstream
I guess this is an historic discharge site that is now pumped elsewhere, likely Chobham sewage works which is 250m downstream.
