Across the Riverina, the State Emergency Service (SES) responded to more than 80 calls for help.

Wagga SES duty officer Josh Hunt told The Daily Advertiser six teams of volunteers were deployed on Friday night to keep up with the demand.

The 20 volunteers that worked overnight received their final call out at around 3am.

When fresh calls came through on Saturday morning, volunteers Sandria Butler and Nathaniel Raine donned the orange uniforms and set to work.

Ms Butler has been an SES volunteer for four years, while Mr Raine has spent a decade with the teams in Wagga.

"Where there is widespread emergency, people in distress, people needing help, that's where we want to jump in and help out," Ms Butler said.

"We watch the [Bureau of Metereology] and when that flags events that are predicted might leave people needing help, that's when we're ready. That's when we try to make ourselves available."

Being volunteers, their lifesaving disaster assistance is secondary to their full-time day jobs.

As well as having a young family, Mr Raine works as a delivery driver.

For Ms Butler, her day-to-day work includes work at the Department of Primary Industries, currently in the bushfire recovery program.

"The thing is, you can't attend everything because you will have work and family commitments," Ms Butler said.

"But anything you can go to, you will go to."

Following the city's drenching of around 60mm in rain, Ms Butler, Mr Raine and the rest of the team gave up their Saturday morning to respond to call-outs in Glenfield Park, Kooringal, Lake Albert and Coolamon.

Mostly, they were assisting with roof leakages, partial home flooding and fallen trees.

But what keeps them coming back, giving up their free time and their weekends, Ms Butler said is the "friendships you make a long the way".

"I really like helping people. People are so thankful when we turn up, we haven't even started doing anything yet and they'll be thanking us just for being there," Ms Butler said.

"You use whatever skill set you have to help the community, you don't have to have a lot of time available. But when you can, you help out."
