Southern Water has been carrying out work in a Rustington road which suffered significant flooding yesterday.
A spokesman confirmed work was underway in Overstrand Avenue in Rustington.
The spokesman said: “Our sewers there are vulnerable when there has been heavy rainfall and one part of the work has been to raise the level of sewer covers in our manholes to make them less vulnerable.
“At the same time we have repaired some damaged pipe.
“We’re also making a clean-up in the area and a road sweeper is being dispatched.
“We have visited customers including those on our Priority Services Register for vulnerable customers in the area and have been liaising with the Chairman of the private estate.”
The spokesman apologised for ‘any inconvenience or distress’ caused.
