Hogsmill River: Spates and Sewage
|View west from Blue Bridge|
Today the Hogsmill reached 1.1m at the Grange Road/Watersplash Close gauging station. This is the highest level since 2000. There is a good website to view this data relayed from gauging stations here https://flood-warning-information.service

Every part of the already hard-pressed sewage infrastructure is overtopped: leaching and leaking; pouring and pooping - a soup of raw sewage. The bankside vegetation captures that which is generally known as 'rag'. This includes the nappy liners, the wet wipes, condoms, tampons, dental floss etc.
This is additional to the daily dosage from the many misconnections polluting every outfall along it's nine mile course. see previous posts on sewage spills and dead fish and rag removal (21.2.16,19.4.16 and 2.5.16) and related Flood risk position and catchement approach (10.3.16, 19.3.16).
