Local actor and musician GK Reginold rides in a small craft through flooded neighborhoods, aiming to deliver essential supplies to those in urgent circumstances.
Many families, Mr Reginold says, have gone without help for days, isolated by the South Asian island nation's worst natural catastrophe in memory.
Cyclone Ditwah lashed the country last week, causing widespread destruction that killed more than 400 people, with hundreds unaccounted for and destroyed 20,000 homes.
But the flooding has also inspired a rise in volunteerism, as people face what the president has described as the "most challenging natural disaster" in its history.
"My primary motivation for getting involved, is to at least ensure they get one meal," he shares. "And I was deeply gratified that I was able to do that."
More than one million people have been affected by the disaster and a national emergency has been declared.
The military has sent helicopters for rescue operations, while relief assistance is arriving from foreign governments and aid groups.
But it will be a long journey to recovery for Sri Lanka, which has seen its fair share of difficulties in recent years.
In a Colombo suburb, individuals who demonstrated in 2022 are now operating a makeshift kitchen that produces meals.
The demonstrations from three years ago were fuelled by a severe economic downturn that caused shortages of fuel, food and medicine. Widespread frustration erupted and led to a leadership shift. Now, that civic energy is being channelled toward cyclone relief.
"Some volunteers came after work, some rotated shifts and some even used vacation time to be there," one organizer explains.
"We mobilized our network as soon as we heard what was happening last Thursday," he says.
The organizer also considers the kitchen as an "extension" of his community service in 2016, when torrential rain and floods affected hundreds across the country.
Volunteers have gathered hundreds of requests for help, sent the information to authorities, and organized the distribution of food.
"Every request we made, we got an overwhelming amount in response from the community," he notes.
A flurry of activity is also happening on the internet, where netizens have created a shared list to direct donations and volunteers.
Another volunteer-backed website helps supporters find relief camps and see what is most needed in those areas.
Local businesses have launched donation drives, while local television channels have initiated an campaign to provide food and basic necessities like soap and toothbrushes.
Amid criticism over the handling of preparations, the president has urged citizens to "put aside all political differences" and "come together to restore the nation".
Critics have claimed authorities of ignoring forecasts, which they say worsened the disaster's effects.
Recently, opposition lawmakers staged a walkout in parliament, arguing that the ruling party was trying to restrict debate on the disaster.
On the ground, however, there remains a sense of unity as people begin the cleanup after the floods.
"In the end, the satisfaction of helping someone else to save lives makes that exhaustion fade," one volunteer wrote after working long hours at aid centers.
"Disasters are not new to us. But, the compassion and size of our hearts is greater than the destruction that occurs during a disaster."
