Here’s the message councillors have received about Stockport’s gritting from Solutions SK (the company wholly owned by Stockport Council which does these sorts of things):
“Over the weekend we have been doing non stop gritting operations, using 440 tonnes of salt.
Due to the road surface temperatures constantly remaining below freezing and frequent heavy snow showers the laying snow and ice will be slow to melt.
From Friday we have been in constant communication with the Met Office throughout the weekend monitoring the situation.
This morning we will be carrying on gritting operations on the tertiary routes along with hand gritting teams from Highways, Cleansing and Grounds with 2 JCB’s working on the High level Roads snow removing.”

I’ve seen no evidence of gritters or any grit for that matter, I live in Gatley. Think Solutions SK are exaggerating their efforts.
ps what happened to ‘pre-emptive’ gritting?
