Then, Gendron hit something.
"We started digging around and we uncovered the top of it. I knew what it was. I've hit one before," he said.
It was a historic, underground cistern, put there around 1869 for fire protection.
The cistern, or reservoir, is basically an old-fashioned water hydrant. The one Gendron discovered is about 20 feet in diameter, 16 feet wide, and held 40,000 gallons of water.
After finding it, Gendron stopped work and notified Lewiston Public Works Director
"The craftsmanship of the brick work is totally amazing, especially considering the times and the tools our forefathers used," Jones wrote on Facebook after inspecting the find.
On Wednesday, Gendron showed off the cistern, uncovered and deep in the ground, to a reporter and photographer.
It's a cool piece of history, he said.
The cistern is made of red brick. It was full of water when they found it.
"It was clear," Gendron said. "You could see right to the bottom. It didn't leak."
Nearby on a sidewalk is a type of manhole cover where for some 150 years water was taken out or poured in.
"They must have filled it because there are no holes to where the water could get in from anywhere," Gendron said.
He should know.
The cistern was uncovered and the dirt around it was cleared. His crews cut a hole in the side and, after the water was drained, Gendron crawled in. With a light, he took photos of the red bricks and mortar.
"It's beautiful. It's more impressive inside than outside," he said.
Gendron joked that he's called a cistern expert.
"People who have been doing this for a long time have never seen one. I've seen three," he said.
Years ago he excavated one on
"It's always in the old parts of town," he said.
Underground cisterns were built to hold water to fight fires before running water.
"It was only in the 1870s that
Water supplies were needed because at that time fire was a serious concern, more so than today. In residential areas, buildings were constructed of wood and built close together. If a fire started, it could easily spread from one building to the next causing serious damage, Hodgkin said.
"For example, the courthouse on
A conflagration is a huge fire that destroys an extensive amount of land and property.

Laborers built the canal and underground cisterns, along with other city infrastructure. The mills were running. Irish and French Canadian immigrants were here and more were arriving every day. In those days immigrants had large families.
With buildings that could easily burn built so close together, insurance companies pressured cities to reduce the risk of fire losses, Hodgkin said.
"They said if you don't do something, insurance rates would be high," he said.
It was common practice to install underground water tanks, he said.

"I hope I don't hit another one," Gendron said.
