Subject: Constituent concern: Thames Water sewage discharge — overflow TWL00139

Dear [your MP — WriteToThem will fill this in],

I am writing as your constituent to raise concern about ongoing sewage discharges
from Thames Water in our area.

A specific recent example is storm overflow TWL00139, which public
Environment Agency data shows the most recent record from public Environment Agency data into the River Wandle.
