Yorkshire Water has invested £1.2m to reduce the risk of sewer flooding to more than a dozen homes in Mirfield.
Engineering specialists Barhale WPS will build a five-metre deep tank capable of holding about 400,000 litres of storm water.
It will hold water until it is safe to be released back into the sewerage system.
The tank will be under a car park behind the Co-op supermarket in Old Bank Road.
A new sewage pumping station will also be built near the tank in Old Bank Road and Sunny Bank Avenue.
Sections on both roads will be closed while it is installed.
Yorkshire Water project manager Liam Saddler said: “We understand that projects of this scale will cause some disruption to our customers but regular sewer flooding has occurred in the area and it is extremely important that we reduce the risk of it happening in the future.
“We would like to apologise for any inconvenience caused to residents, businesses and road-users. Please be assured we’ll do everything we can to keep disruption to a minimum.”
The work starts on Monday July 7 and will last eight weeks.
To raise awareness of the project, Yorkshire Water will hold an event on Thursday July 3 at Mirfield Community Centre, from 4.30pm to 7pm.
