People are beginning the clear-up after flash flooding caused damage across the region yesterday.
In Essex there are calls for an investigation after 200 homes were flooded on Canvey Island.
More than two inches of rain fell but at the same time the pump system that takes water out into the Thames Estuary failed because of a lightning strike.
Meanwhile, Norwich was the wettest part in the UK and several homes were flooded.
Residents want to see more done so the city can cope better with flash flooding in future.
"The last few summers, they've been fairly dry.
So, they seem to have left the drains and not serviced them, but not just in this area, it seems around the city as well.
What they are now doing is reactive.
If it was preventative, maybe it would never have flooded in the first place."
Parts of Norwich saw a month's worth of rain falling in a hour on Sunday causing flash flooding in some parts of the city. Norwich was the wettest place in the UK.
Norwich airport recorded 46 mm (1.8 inches) of rain between 3pm and 4pm which is more than normally falls in three weeks.
An unofficial reading in the Carrow Road area reported 57 mm in half an hour.
The torrential downpours were isolated with some areas in the Anglia region escaping with very little rain.
