You can check when your street is cleaned https://www.wirral.gov.uk/environmental-problems/street-care-and-cleaning/street-cleaning#wgSM-4Borough Road, Birkenhead appeared to have someone round in the middle of the rain unclogging drains, there were a large number of blocked drains earlier on then clear later. I believe down towards Well Lane there was about two feet of water at one point. Looks like a large manhole cover might have blown on Kings Road around Brimstage Avenue, the road surface was raised around the manhole and a fire engine was down the drive of a house opposite.

Yeh, I'm back if that's ok. ? Missed you all.
The lady along the road from us had a manhole cover blown in her garden, which resulted in sewage everywhere. It was pretty violent here, but seemed to drain away quickly after the torrent stopped. I have never seen my garden flooded in 22 yrs, but it was the other day.
Who had their canoe out in BIrkenhead. ? Ha.

People tend to forget the thing about blown manhole covers. When I see people on tv wading through soupy floodwater, I have the horrors about someone falling down a manhole! Edit: Wheee, just noticed this is my thousandth post!

Street grids and drains are responsibility of the Council, the main pipes are the responsibility of United Utilities.
There is no resolution to sudden hard downpours, in the southern parts of the USA where they have regular hard downpours they have absolutely huge grids (I've seen 8ft X 6ft grids in roads) and massive amounts of stormwater storage and levees, the hardest rain still catches them out and roads and property flood.
You could throw a lot of money at it but are us the users prepared to pay?
Generally the priority in the UK is to protect houses over roads, which is a sensible approach.
Older district in the UK have combined surface and foul water drains which compounds the issue, we try to capture and store nearly all of that water - admittedly some companies have performed poorly in that respect where they release the water untreated. It is exceedingly rare to have foul water backing up in houses in this area.
Newer house have separate foul and surface water drainage which enables better capture of surface water in open stormwater storage. But land is expensive and using it for storm water storage needs a lot of money. In places we have massive underground tanks but they are hugely expensive to build.
Bursting roads/manholes are also reasonably rare but wherever there is higher ground near lower ground there will always be some risk. 90ft of water exerts about 40 psi pressure, on a 2ft X 2ft manhole that is roughly 11.5 tons of force, easy to contain in a downwards direction, much more difficult in an upward direction without 10 tons of counterweight for each manhole. Fortunately it acts as a release otherwise that pressure could arrive in houses.
Its not perfect but generally we are somewhere around a reasonable compromise between cost and effectiveness around here, other parts of the country have much worse problems, not helped by corruption within the industry thanks to us hiving this service out to foreign countries/companies
Of course, I believe it should be a public utility but it appears I am outvoted by capitalists - you get what you vote for.
In summary, are you prepared to pay for a better system and have a proportion of that money given away to financial gamblers?

Thanks to Cools and Mikeeb. I have been waiting for something like an interesting topic to appear, ones which can involve more members , but so far no luck.
