How much sewage is ending up in the Sid? part three

The government published its latest response to public concerns about ‘storm overflows’ in August – although it seems to be saying that 2020 is the baseline and that discharges will be possible until 2050:

“by 2025, water companies will have reduced overflows discharges from 2020 levels by around 25%.”  

“By 2035, water companies will have: improved all overflows discharging into or near every designated bathing water; and improved 75% of overflows discharging to high priority sites.” 

By 2050, no storm overflows will be permitted to operate outside of unusually heavy rainfall or to cause any adverse ecological harm.” 


Meanwhile, Thames Water, one of the highest culprits when it comes to ‘storm discharges’ is letting its customers know when it happens:
