Gently Flows the Sewage

I suppose we have to applaud any sign of 'transparency'. It seems odd, however, that Thames Water seem almost proud, they have created an interactive digital map of sewage discharges from their water treatment plants into rivers in that area (https://www.theguardian.com/environment/2023/jan/23/thames-waters-real-time-map-raw-sewage-discharges-rivers). There are thousands of hours of sewage discharges from Thames Water. Discharges are only supposed to happen, when treatment plants are 'overwhelmed' by extraordinary weather events. They do, however, save the private company money, that can be directed to shareholders. Residents, in the Thames area, can now track, when limpid chalk-water streams will turn brown! I suppose the shareholders might also be interested, as the changes parallel the water company profits.
