Workers faced a race against time to erect Bewdley's flood defence barriers as more heavy rain was forecast to hit the area within the next 12 hours.
The crew waded into action ahead of the normal river levels that would trigger the installation of the temporary barriers because of that forecast.
Their action could save 62 properties - homes and businesses - that would be under threat of flooding.
And with insurance estimates that flooding could cause an estimated £30,000 per property in damage that would save a lot of cash and grief.
Environment Agency spokesman Chris Bainger said eight workers would spend around four hours erecting stanchions along a 170 metre stretch of Severnside North and slotting in aluminium panels to hold back any flooding.
Other members of the team brought the equipment from its storage depot in Kidderminster.
He said: "Over the next 12 hours heavy rain is forecast.
"The ground is already saturated so that could bring river levels, already running high and fast, up to the level where the river could flood."
After the barriers are in place the Environment Agency will man the river bank 24 hours a day to monitor the situation until the flood threat is over.
