Subject: Constituent concern: Thames Water sewage discharge — overflow TWL00437

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 TWL00437, which public
Environment Agency data shows recording 1 spill events totalling 4 days in the last 30 days into the Tributary of Bow Brook.

Evidence on the public record:
- Last 30 days: 1 spill events totalling 4 days
- Cross-referenced flags from independent monitoring: 1 open Truth Engine discrepancies
- Location: 51.32129, -1.14956

I would like to ask:

   and monitor coverage in particular

   for Environment, Food and Rural Affairs or with Ofwat
3. What steps Parliament is taking to hold Thames Water accountable for

   the ground
